Slides of SNMP (Simple network management protocol)Shahrukh Ali Khan
SNMP is a protocol for remotely managing and monitoring devices on a network. It allows network administrators to manage nodes by retrieving and setting configuration parameters like IP addresses, counters, and software versions. SNMP uses agents running on devices which collect data and send it to managing nodes upon request or autonomously via traps. It operates over UDP on ports 161 and 162 using a simple request-response model.
The DNS name resolution process involves a DNS server checking its local cache, hosts file, and forwarding the request to higher-level DNS servers if the address is not found. As a last resort, the root hints file is used to forward the request to a root DNS server, which will then direct the request to a top-level domain server that can provide the IP address. DNS translates hostnames to IP addresses through a hierarchical system of root, top-level, and authoritative DNS servers.
The document discusses the Domain Name System (DNS), which translates domain names to IP addresses. It has three main components: the name space that defines the domain name structure, resolvers that extract information from name servers, and name servers that store information about the domain name structure. The DNS uses a hierarchical and distributed database to map domain names to IP addresses across a network like the internet.
RISC and CISC architectures evolved from different philosophies for optimizing computer performance given the constraints of early computing technologies.

Advanced Storytelling Concepts for MarketersEd Shimp
Every marketer knows you’re supposed to tell a story, but do you know how to tell a story? Do you know why you’re supposed to tell a story? Do you even truly know what a story is? While many marketing presentations emphasize the value of mythic storytelling, the nuts and bolts of actually constructing a story are never explored.
The goal of marketing may be to achieve specific KPIs that drive sales, which is very objective, but the top of the marketing funnel requires a softer approach. In our data-driven results-oriented fast-paced world, marketers must quantify results, but those results will never be achieved unless prospects are first approached with humanity.
There is a common misunderstanding that the so-called “soft skills” of marketing such as language and art are unmeasurable and subjective, but while the objective measures of market research are merely 100 years old, the rules of aesthetics have been perfected over the last 2,500 years.
Great story construction is a skill that requires significant knowledge and practice. This presentation will be a review of the ancient art of story construction.
We will discuss:
• Rhetoric – The art of effective communication
• The Socratic Method – You cannot teach, but you can persuade people to learn
• Plato’s Cave – You sell products, but you market ideas
• Aristotle’s Six Dramatic Elements – The secret recipe for marketing stories
This is for senior marketers who are tasked with creating effective narratives or guiding others in the process. By the end of the session, attendees will have gained the knowledge needed to work storytelling into all phases of the buyer’s journey.
We’ve entered a new era in digital. Search and AI are colliding, in more ways than one. And they all have major implications for marketers.
• SEOs now use AI to optimize content.
• Google now uses AI to generate answers.
• Users are skipping search completely. They can now use AI to get answers. So AI has changed everything …or maybe not. Our audience hasn’t changed. Their information needs haven’t changed. Their perception of quality hasn’t changed. In reality, the most important things haven’t changed at all. In this session, you’ll learn the impact of AI. And you’ll learn ways that AI can make us better at the classic challenges: getting discovered, connecting through content and staying top of mind with the people who matter most. We’ll use timely tools to rebuild timeless foundations. We’ll do better basics, but with the most advanced techniques. Andy will share a set of frameworks, prompts and techniques for better digital basics, using the latest tools of today. And in the end, Andy will consider - in a brief glimpse - what might be the biggest change of all, and how to expand your footprint in the new digital landscape.

ABSTRACT
A blade
server is
a
stripped
down server
computer with
a modular
design optimized to minimize the use of physical space and energy. Whereas a
standard mount server can function with (at least) a power cord and network
cable, blade servers have many components removed to save space, minimize
power consumption and other considerations, while still having all the
functional components to be considered a computer. A blade enclosure, which
can hold multiple blade servers, provides services such as power, cooling,
networking, various interconnects and management. Together, blades and the
blade enclosure form the blade system. (Different blade providers have differing
principles regarding what to include in the blade itself, and in the blade system
altogether.)
In a standard server-rack configuration, 1U (one rack unit, 19" [48 cm] wide
and 1.75" [4.45 cm] tall) defines the minimum possible size of any equipment.
The principal benefit and justification of blade computing relates to lifting this
restriction so as to reduce size requirements. The most common computer
rack form-factor is 42U high, which limits the number of discrete computer
devices directly mountable in a rack to 42 components. Blades do not have this
limitation; a
s of 2009, densities of up to 128 discrete servers per rack are achievable with
blade systems.

1. INTRODUCTION
With the high cost of data center floor space and current advances in technology, new
installations with denser cabinets that require more power and cooling continues to be
the trend. Besides the challenges that new installations present, equipment cabinet
upgrades can also be a problem as the existing power and cooling currently provided
may not support the new cabinet configuration.

High density applications like cluster server configurations have in some cases pushed
the kW power demands as high as 40 kW per cabinet. The required power depends on
the equipment, how dense the cabinet is and whether redundancy is required. This has
led to new and innovative solutions for providing cabinet level power utilizing CDU’s

(Cabinet distribution Units).Distributed server architectures based upon "blades" are
rapidly emerging in the data centers of corporations and Internet service providers.
Historically, servers only assumed the form factor of a re-purposed desktop computer or
rack-mountable appliance. These servers utilized high-quality components and leverage
additional memory and hard disk capacity. Now server form factors are evolving into
single PC cards that can be plugged into a chassis as a single module. Bladed servers
stack numerous independent lower-end servers within a single chassis. Chassis can
accept anywhere from eight to 24 blades. Each blade is an independent system with its
own memory, processor and network connection. Due to their compact size, multiple
blade servers can be placed in a single server rack or enclosure, allowing numerous
systems to share electricity and HVAC resources. Gartner Dataquest predicts that
worldwide server blade shipments will increase from 84,410 units in 2002 to more than
one million in 2006. The IT research firm anticipates that revenue from server blades
will reach at least $1.2 billion during this time period. Blades are thus becoming the one
major segment of the server market that is experiencing escalating growth. The
popularity and fast growth of the blade server can be attributed to cost-savings that the
device accrues to its users, especially hosting firms and service providers. Because
more than 250 blade servers can be effectively placed into a single rack, it is possible
for hosting firms with data center operations to quadruple their hosting capacity with
the devices. By comparison, most of today's low-end servers have only a single
computer in one enclosure, allowing only one 42 systems to fit in an industry-standard
rack. Because blade servers are small, consume less power and generate less heat than
an average server, they are emerging as an ever-popular option for niche Web hosting
services. With the cost of data center space at approximately $300 per square foot and
with energy costs increasing throughout continental North America due to deregulation,

blade servers have become the de facto standard for increasing data center profitability.
The systems are typically used as Web servers and caching servers that deliver Web
pages to Internet browsers, SSL servers for encrypted communication, and streaming
servers for audio and video transmissions. Most hosting companies and service
providers appreciate the devices because they are easy to install and employ dedicated
software that improves their administration, performance and reliability. The devices
are also increasingly being utilized as firewall devices and to increase capacity in
corporate data centers. Blade severs are excellent devices for hosting companies with
large existing data center deployments who want to capitalize upon existing PCI
expansion space. The inclusion of a single blade allows a hosting company to double its
computing power or hosting offering, utilizing the same amount of physical space. The
main disadvantage concerning PCI-based blade servers is that the processors are usually
not as robust as traditional high-end servers. This factor limits the use of the server to
functions such as low-end Web hosting. While blade severs have the capacity to serve
streaming video and other demanding applications, often the emerging technology is
used for back up or storage purposes. Lower-end models usually depend on server or
operating system virtualization, causing the server to run much slower than traditional
equipment. It is thus incumbent upon a reseller to determine whether a hosting company
is utilizing blade servers for mission-critical deployments and whether those servers can
accommodate demanding applications. Resellers who operate their own equipment
might want to consider utilizing blade servers as an effective technology to add firewall
or other security specific capacities to their collocated equipment.

2. HISTORY
Developers placed complete microcomputers on cards and packaged them in
standard 19-inch racks in the 1970s soon after the introduction of 8-bit microprocessors.
This architecture operated in the industrial process control industry as an alternative
to minicomputer control-systems. Early models stored programs in EPROM and were
limited to a single function with a small real-time executive.
The VME bus architecture (ca. 1981) defined a computer interface which included
implementation of a board-level computer installed in a chassis backplane with multiple
slots for pluggable boards to provide I/O, memory, or additional computing. The PCI
Industrial Computer Manufacturers Group PICMG developed a chassis/blade structure
for the then emerging Peripheral Component Interconnect bus PCI which is
called Compact PCI. Common among these chassis based computers was the fact that
the entire chassis was a single system. While a chassis might include multiple
computing elements to provide the desired level of performance and redundancy, there
was always one board in charge, one master board coordinating the operation of the
entire system.
PICMG expanded the Compact PCI specification with the use of standard Ethernet
connectivity between boards across the backplane. The PICMG 2.16 Compact PCI
Packet Switching Backplane specification was adopted in Sept 2001 (PICMG
specifications). This provided the first open architecture for a multi-server chassis.
PICMG followed with the larger and more feature-rich Advanced TCA specification
targeting the telecom industry's need for a high availability and dense computing
platform with extended product life (10+ years). While Advanced TCA system and

boards typically sell for higher prices than blade servers, Advanced TCA suppliers
claim that low operating-expenses and total-cost-of-ownership can make Advanced
TCA-based solutions a cost-effective alternative for many building blocks of the next
generation telecom network.
The first commercialized blade server architecture was invented by Christopher
Hipp and David Kirkeby and their US 6411506was assigned to Houston-based RLX
Technologies. RLX, which consisted of mostly former Compaq Computer Corp
employees, including Hipp and Kirkeby, shipped the first commercial blade server in
2001 and were acquired by Hewlett Packard (HP) in 2005.
In February 2006, Blade.org was established to increase the number of blade platform
solutions available for customers and to accelerate the process of bringing them to
market. It is a collaborative organization and developer community focused on
accelerating the development and adoption of IBM blade server platforms.
The name blade server appeared when a card included the processor, memory, I/O and
non-volatile program storage (flash memory or small hard(s)). This allowed
manufacturers to package a complete server, with its operating system and applications,
on a single card / board / blade. These blades could then operate independently within a
common chassis, doing the work of multiple separate server boxes more efficiently. In
addition to the most obvious benefit of this packaging (less space-consumption),
additional efficiency benefits have become clear in power, cooling, management, and
networking due to the pooling or sharing of common infrastructure to supports the
entire chassis, rather than providing each of these on a per server box basis.

3. FEATURES
Essentially, blade servers are a card on the server: a single motherboard that contains a
complete computer system, including processors, memory, network connections and
related electronic devices. If you insert a number of blade server rack or cabinet in the
plane, then the rack or cabinet infrastructure can be shared, at the same time with
redundant features. Recognized the advantages of blade servers have two, one to
overcome the shortcomings of the cluster server chip, and the other is optimized to
achieve the cabinet.
Then choose the main blade server for several reasons to consider the following:
1.Lower Hardware Costs
Server with the traditional difference is that each blade server rack and does not need a
separate infrastructure, relatively low-cost blade servers. Multiple systems through the
sharing of power and cooling equipment, management of hardware and cabling systems
can greatly reduce the cost of each server.
2. Simplified Deployment and Maintenance
The deployment of multiple servers is a time-consuming and resource-intensive

process. Administrators need to be installed on each server rack for power and network
cabling,
and to install the software. In high-density environment, in particular the deployment of
wiring is a headache in one of the problems. The use of blade servers, administrators
only need to be installed on the rack and wiring, no need to separate the blade server
routing. The addition of new computer resources or just insert a new blade server, just
like now to add a hard drive as easy. Because blade servers can share a number of
redundant power supply, so to minimize the wiring of the rack. In addition, the built-in
converter to Ethernet data and management networks, and even integrated with KVM
connection.
The use of automated software tools, administrators can operate through a network; we
can quickly and easily install the software to one or more blade servers. Upon
completion of the blade server software installed, the administrator will be able to use
remote management tools to conduct a comprehensive management.
3. To Maximize the Use of Data Center Space
According to the design and the different suppliers, blade servers can make the server
than the current density of rack-optimized 1U system increased 100% to 8000%.
4. To Reduce Power Consumption
Blade servers in order to reduce power consumption, the majority of suppliers will be in

some blade servers use low-power processor. Even if the blade server does not use lowpower processors, the power consumption is less than "comprehensive" server, blade
server power consumption because fewer components. In addition, suppliers can afford
to use high-efficiency power supply costs, because power will be shared across multiple
servers. In addition, blade servers as a result of lower power consumption, they produce
less heat, thus reducing the power consumption of the cooling system.
At present, such high-density blade server market prospects brought about by foreign
countries has been IBM, HP, SUN and DELL and other manufacturers of the value,
they have announced the launch of its own blade servers. Domestic dawn, Lenovo, and
other companies have also launched a wave of their respective products, as a result of
the overall performance of blade servers more performance, so blade servers will be
more business users of all ages.

4.TYPES
Since blade enclosures provide a standard method for delivering basic services to
computer devices, other types of devices can also utilize blade enclosures. Blades
providing switching, routing, storage, SAN and fiber-channel access can slot into the
enclosure to provide these services to all members of the enclosure.
Blade vs. Rack mount
Blade servers are outgrowing at a faster rate than traditional rack mount servers. A
recent Gartner study found that blade servers are the fastest growing segment of the
server market. One reason is simply because blades are easy to configure and manage.
Using a blade can be as easy as using an expansion card — only this "expansion card"
comes with one to four processors, memory and disk storage. Blades are considered to
be hot-swappable, which means you can add new blades or remove existing ones while
the system is powered on. Traditionally, blade servers have been deployed in data
centers and large enterprise environments, but the small business is looking at blades
for the same reason enterprise has previously: They take up less floor space than
traditional rack mount servers, they require less power and fewer IT management
resources are required than with a rack mount. Blade servers are scalable to any
physical infrastructure.
It is important to remember that blades are not suited to all applications and cannot
replace a large-scale server in all instances. There is an also proprietary interest at stake.
An HP blade, for example, cannot be plugged into an IBM blade chassis. As a result,
third-party vendor blades have to be designed for specific branded chassis.

Virtualization & Common Blade Server Computing Environments
Virtualization is another area of computing that has been a driving force behind blades.
Virtualization involves emulating multiple servers on one hardware platform. Running
multiple operating systems on a single computer or storage virtualization where you
have the amalgamation of multiple network storage devices into what appears to be a
single storage unit are examples of virtualization. With a blade server you have the
option to combine blades with virtualization software to consolidate workloads, each
running on its own instance of the OS (using the same or a different OS). With blades,
separate operating systems and applications can co-exist on one server and users of the
system are able to access more memory and processing power as their workload
demands it.
Blades are frequently deployed in data centers and high-performance computing
environments (a branch of computer science that concentrates on developing
supercomputers and software to run on supercomputers.), and can serve as
application servers, databases, e-mail or Web servers, and more. Large data centers
and telecommunications service providers benefit from the use of blades as they
provide the means for a large business to respond quickly to changes in business
conditions. High-traffic Web sites are another example of where blades can help — if
you plan to host an online event, broadcast events live or something of that nature
blades are a perfect solution as they allow you to quickly add memory and processing
power to compensate for unusually high traffic to the Web site.
Overall, where a business or group would use several different servers for different
applications, it makes sense to combine the multiple servers into one blade server to
make for better manageability. Blades are often viewed as a solution for large

vendors market specific blade solutions and packages to the SMB.

5. ADVANTAGES AND DISADVANTAGE
ADVANTAGES
Condensed, high-density...
Blade servers allow more processing power in less space which simplifies cabling,
storage, and maintenance. Blades are often used for grid computing. The advantage of
blade servers is not only that one "cabinet" houses multiple servers that share power
source and other components, but also from the consolidation of related resources, such
as storage and networking equipment, into a smaller architecture than would be the case
with a farm of regular servers.
Load balancing and failover...
Like most clustering applications, another advantage of blade servers is that blade
servers can be managed to include load balancing and failover capabilities. This can be
done with a farm of regular servers as well, but since blade servers share much simpler
and slimmer infrastructure and often come designed for this task from the manufacturer,
load balancing and failover management tends to be easier with blades.
In case any hardware failure is found on a server blade or the chassis itself, selfdiagnostics function automatically starts and the faulty area can be identified by the
indicator display per server blade.
Dept. of Computer Engg.

MTI Thrissur
19. Seminar 2013-14
BLADE SERVER
Power consumption & power management...
A blade server most importantly reduces power consumption and improves power
management. Consolidating power supplies into the blade chassis reduces the number
of separate power supplies needed and also reduces the power requirements per server.
Because individual server blades are stripped to bare minimum and do not have other
features found in conventional servers such as keyboard, graphic cards, and others, that
employ less devices that need to be powered. This reduces overall power consumption.
One blade server with 16 server blades uses much less power than 16 individual fullsize servers.
Lower management cost...
Another big advantage over traditional servers. Blade servers often come with a single
interface that is used to manage all individual servers within chassis. Server
consolidation and resource centralization also simplifies server deployment,
management, and administration.
Dept. of Computer Engg.

MTI Thrissur
20. Seminar 2013-14
BLADE SERVER
Hardware configuration management, operation status monitoring, and fault monitoring
are centrally controlled, thus reducing the system administrator’s burden. Administrator
can be notified of an error by such means as e-mail in a timely manner
Network and other cabling...
Imagine that you have 16 individual stand-alone servers. Each of them needs to be
connected to the network which calls for yards or even miles of cabling. Blade servers
simplify cabling requirements and reduce wiring by a great percentage. Power cabling,
operator wiring (keyboard, mouse, etc.) and communications cabling (Ethernet, SAN
connections, and cluster connection) are greatly reduced as well.
Flexibility, modularity, and ease of upgrading...
Modern blade servers are designed in a way that it is possible to take out and add in
server blades while the system is up and running with just a minor configuration in the
admin interface. New processor, communications, storage and interconnect technology
can be implemented in blades that install into existing equipment with no or minimal
disruption to the functionality of the whole system. You can expand or reconfigure the
system without stopping your jobs other than those related to the server blade subject to
upgrade or replacement.
Modules can mix in the same blade server chassis. Server blades within a chassis do not
necessarily need to be identical. Depending on the particular type of your chassis, one
server blade can have for example Intel Xeon and the other Intel Itanium. You can have
one server blade with Windows and another one with Linux.
Dept. of Computer Engg.
20
MTI Thrissur
21. Seminar 2013-14
BLADE SERVER
Deployment and scalability...
The same applies for adding new server blades into the system. Once a blade server
chassis has been installed, additional servers can be added by simply sliding them into
additional bays while the system as a whole is up and running.
Blades can be scaled up as needed by just simply adding a new server blade. It is
certainly easier to deploy additional server blade than a new stand-alone server.
Disaster management...
Even though the purpose of packing server blades into a single chassis is to share
servicing resources, chassis can be configured with redundant power modules for
failover.
DISADVANTAGES
As with anything, benefits do not come for free. Blades also include some
disadvantages.
Expensive configuration...
Although plugging in a new server blade into the blade server is easy once the system is
running, initial configuration can be labor-intensive and expensive in complex
application environments. This disadvantage comes with the fact that blade servers are
specialized computing equipment and their configuration and administration often
requires training provided by the vendor which may not be cheap unless you have a
special free-training deal with the vendor.
Dept. of Computer Engg.
21
MTI Thrissur
22. Seminar 2013-14
BLADE SERVER
Expensive tool, i.e. economies of scale...
If you do not fill the blade chassis with server blades, you are not fully utilizing it. It
does not make much sense to purchase a blade chassis for $5,000 and then run the
whole system with just 2 server blades in it. Blade chassis are often made to hold 14 or
16 server blades.
The general rule of thumb is that blade servers are not suitable and economical for
applications requiring less than 5-10 servers. Applications requiring less than 5-10
server blades (10-20 CPUs) are best devoted to standalone server systems.
Vendor-lock...
Blade systems vary between manufacturers. Once you spend $50,000 on a blade server
from a particular vendor, it is not always easy to switch to another vendor because of
servicing agreements and also because a competitor is unlikely going to have the same
expertise in your equipment as your vendor.
You could theoretically use your server blades in competitor's blade chassis, but
practically blade chassis are not standardized. It is unlikely that IBM would get together
with Dell and HP to share chassis. Chassis is what makes their products unique. Server
blades are often designed to only run in the company's own chassis.
Business case...
Blade servers are not the best solution for everything. If you have a very large
transaction processing application requiring high read/write ratios, then you may run
Dept. of Computer Engg.
22
MTI Thrissur
23. Seminar 2013-14
BLADE SERVER
into bottle neck with your bus speeds, memory limitations, disk access, and network
I/O. Email and Web serving are situations where blade computing suits well.
Heating and cooling...
One often forgotten disadvantage is HVAC. While individual stand-alone servers can
be distributed throughout the building and may not necessarily need special
accommodations for cooling, blade servers being very powerful these days produce
massive amounts of heat per square foot. If untreated, this could melt them down. When
purchasing blade servers, it is important to keep in mind that additional resources will
be needed also for HVAC.
6. APPLICATIONS
As blade servers pack increasingly more punch into smaller form-factors, their use is
spreading beyond data center applications. The integration of newer technologies makes
blades attractive for high-performance computing purposes such as distributed
computing, rendering/imaging and data analysis.
Blade servers have gained ground over the past few years as an efficient, condensed
computing solution in large data center implementations. They are widely used as
replacements for pizza box servers and large rack mounts (Figure 1).

The advantages inherent in blade server technology include smaller form-factors,
denser computing, expandability, hot-swap capabilities, flexible and fail-safe
architecture, reduced downtime, increased redundancy, simplified server management,
easier hardware and software integration, and lower heat dissipation and power
requirements. These improvements over traditional data center servers provide for a
massive increase in deployable resource density and an overall reduction in long-term
costs.
Each blade in a chassis is typically a self-contained server. Data center consolidation,
advanced communications and remote management of servers required to run 24/7 are
just a few of the reasons for large-scale deployments. These deployments are becoming
more popular for telecom, telephone and cellular carriers, insurance companies, tax
preparers, state and local government agencies and educational institutions, among
others.
Although blade servers have a long way to go before they are the standard deployed
technology throughout the data center, they are beginning to appear in less traditional
implementations such as high-performance computing (HPC).

POWER SELECTION AND DISTRIBUTION FOR HIGH DENSITY CABINETS
There are many different circuit combinations that can be used to provide power to today’s
densely populated cabinets. Today’s total power requirements for rack mounted devices,
per cabinet, can be as low as a 2-3 kW’s but may exceed 40kW depending on the
application, whether redundant power is required and of course, the devices that are
installed within the cabinet. Many servers today are designed to take a large range of input
voltage from 120V to 208V. Typically smaller servers that may or may not be rack
mountable require 120 V. Most of today’s larger high density servers, such as blade
servers require 208V power. While the floor space required achieving a constant level of
computing and storage capacity has shrunk, the energy efficiency of the equipment has not
increased at the same rate. As a result, the power consumed and the heat dissipated has
increased significantly within the cabinet foot print. With increased power consumption (a
trend that is likely to continue) comes important decisions that must be made with regards
to cabinet level power requirements and selecting the proper CDU (Cabinet Distribution
Unit). Tough choices like what power is brought down to the cabinet level such as 120V
15 or 20A, 208V 20 or 30A, 208V 30A 3-Phase or even 208V 60A 3-Phase are important
decisions that affect costs, performance and the ability to provide for future expansion.
The number of power drops that must be run to each cabinet greatly affects the cost and
whether or not there is sufficient power available for current needs and expansion. This is
especially true in critical applications where redundant power is necessary. Each power
drop run to a cabinet costs $500 to $1,500 or more; as well as having other consequences
such as the number of CDU’s required or whether or not cable management is a problem.

8. FUTURE SCOPE
Only time will tell if future capacity demands will continue to increase power
consumption and cooling levels to higher and higher levels. Current ASHRAE
projections certainly predict that they will. Other technologies such as virtualization,
dual core processors, and new more efficient processor designs along with current and
future software solutions will ultimately determine the outcome.
Blades help enable virtualization. Virtualization allows data centers to tune resources
dynamically to business needs—as they change. Virtualization in the modular computing
paradigm decouples resources from any particular need: resources are seen as pools that can
be reconfigured and redeployed according to demand. Blade modularity plus virtualization
tools allow IT departments to step away from traditional data Center approaches and make
resources more pliable to changes in business activities and needs, while reducing
management burden. Resources can be dynamically optimized and adapted for any
application. Virtualization tools will enable automated redeployment of servers, operating
systems and application software and allow reconfiguration of switches on the fly, based on
data center policies, business planning and strategy and system monitors, threshold triggers
and control mechanisms. And it will happen without an administrator visiting the
equipment. For example, retail stores or airlines running special Web-only sales events
can automatically redeploy underutilized resources to the front-end Web services to
maintain service levels to customers. Also, if sales or service demands unexpectedly
increase; policy-driven, blades-based modular data center can shift resources in minutes
instead of hours to accommodate the loads while administrator is working on some other
critical initiative.

9. CONCLUSION
It is clear that by close review of the application and it’s power requirements decisions
can be made that will allow for future expansion, denser cabinets, greatly reduced costs (in
many cases), power redundancy (if required) and will optimize cable and CDU
requirements. It is only through making the power requirements a priority at the beginning
of the project rather than an afterthought that these goals are achieved. This has become
especially important with today’s higher power demands and the ever increasing push for
lower costs, greater efficiencies and improved uptime availability.
