IT Brand Pulse industry brief describing a new approach to configuring virtual networks for virtual machines...layering hypervisor-based virtual networking services on top of hardware based virtual networking services. The result is more efficient management and lower costs.
As organizations deploy converged infrastructure environments, entry costs play a significant role in hardware selection. Choosing a solution that provides easy upgrade paths when increased performance and capacity are necessary is another important factor. However, as our analysis demonstrates, it is equally important to consider the future costs associated with those upgrades. Selecting hardware based solely on initial acquisition costs can lead to substantially higher costs for future bandwidth increases.
We compare the total list pricing for each tier of the Cisco UCS solution and the IBM Flex System solution to highlight the differences in the cost of bandwidth between each environment. Not only does the Cisco UCS solution have a 22.3 percent lower initial investment cost, but the costs to increase bandwidth above the baseline configuration are significantly lower than doing so on the IBM Flex System.
Fault tolerance performance and scalability comparison: NEC hardware-based FT...Principled Technologies
Being able to rely on your server solution to deliver uncompromising levels of performance across a large number of VMs and to maintain these levels during an outage is a very appealing prospect. NEC Express5800/R320d-M4 servers with hardware-based fault tolerance can let you do just this.
In our datacenter, the hardware-based NEC solution with eight VMs achieved more than 2.4 times the performance of the software-based solution using VMware vSphere and recovered from a service interruption without downtime or performance loss. In addition, the hardware-based NEC solution did not require a dedicated 10-Gigabit network infrastructure to provide fault tolerance to the VMs. These advantages make the NEC Express5800/R320d-M4 server an excellent option for those businesses that don’t want to choose between strong performance and fault tolerance.

Wide Area Network Design
An enterprise network is a diverse and large network connecting most major points in a company, business or other organization. An enterprise differs from a WAN in that it is privately owned and maintained. There are a variety of WAN technologies to meet the different needs of businesses and many ways to scale the network. An enterprise must subscribe to a WAN service provider to use WAN carrier network services (Paquet, 2013).
In designing of the WAN portion of the network, the first step is to understand the specific network characteristics of the various locations from a Wide Area Network point of view and to then analyze and decide how to implement WAN connectivity at each location. The proposed WAN has specified both possible leased line as well as point to point radio connectivity between sites (Zhang, 2005). It is recommended that the wide area network connection between remote offices should be a point to point radio link. The Plant facility in one location has the capability of using satellite communications or other leased lines for this deployment. Also, for high availability it is recommended that all locations also have site to site redundant links over the Internet through the use of (virtual private network) VPN connectivity. VPN technology will enable organization to create private networks over the public Internet infrastructure that will maintain security and confidentiality. We will use VPNs to provide a virtual WAN infrastructure that connects branch offices to all or portions of their corporate network.
Different applications require varying amounts of network bandwidth the bandwidth required between these sites is dependent upon several factors that include amount of traffic (which varies depending upon the number of users connected to the network), number of hosts, number of network users, protocol being used, potential applications deployed on the network and the network design. For offices with lower bandwidth requirements the most recommended Frame Relay connection should provide no less than 768Kbps while locations with a larger bandwidth requirement will need point to point T1 connections (around 1.54Mbps). To determine which type of connection is appropriate at each location, a list of the approximate number of users and hosts at each site along with the applications they use will be we put in consideration when coming up with the equation for properly determining bandwidth requirements for the network. The required bandwidth in this case will be measured by first determining the amount of space available to transfer data. So for the T1 connections we need to divide 1.54Mbps by 8 to get the number of bytes per second available on the WAN connection. Therefore, a T1 connection will support 192 Mbps. Next, we will determine the amount of bandwidth needed for each application, which.
Industry Brief: Streamlining Server Connectivity: It Starts at the TopIT Brand Pulse
An overview of how virtual I/O has emerged to efficiently deliver more I/O bandwidth by virtualizing physical links, and supporting multiple I/O protocols in each Virtual I/O system.
virtualization is the solution to the under utilization problem. And the essence of virtualization is an abstraction layer of software called the Hypervisor.
TECHNICAL WHITE PAPER: NetBackup Appliances WAN OptimizationSymantec
In a world of ever increasing data flow as well as globalization of data centers the effectiveness and utilization of the networks connecting sites is of the highest importance to end users. Even with network enhancement and improvement, the ability of the infrastructure to keep pace with the flow of data has proved not to be in lockstep. To optimize the flow of data verses increasing the pipe that is flows along is seen as critical to keeping operations running and costs minimal. This paper discusses the new WAN Optimization technology that has been introduced in the NetBackup 5220 and 5020 appliances.
This document outlines the WAN Optimization feature enhancements introduced on the NetBackup 5220 and NetBackup 5020 and applies to:
• NetBackup 5220 & 5230 appliances with version N2.5 and above installed
• NetBackup 5020 & 5030 appliances with version D1.4.2 and above installed

Impact of network quality deterioration on user’s perceived operability and l...IJCNCJournal
The remote desktop environment (Virtual Desktop Infrastructure) is attracting interest as a way to
strengthen security and support mobile access ortelework. To realize the remote desktop environments, a remote desktop protocol is required to transfer information via a network about the user’s operations made on the keyboard and mouse on a terminal to the remote server. The growing popularity of remote desktop environments makes it important to determine the factors that govern the user’s perceived operability with a remote desktop protocol. It is also necessary important to find out the conditions for a wide- area live migration of virtual machines, to use resources efficiently in the remote desktop environments.
This paper examines the impact of network quality deterioration (long network delay, high packet loss,
small downlink bandwidth) on a user’s perceived operability in remote desktop environments, assuming
RDP, PCoIP and ICA as remote desktop protocol. Next, this paper studies the impact of network quality on
the performance of a live-migration of virtual machines in remote desktop environments.

2. Heterogeneous Workloads
Virtualization Comes of Age
The maturation of virtualization platforms, highlighted by the
recent releases of VMware vSphere 5.1 and Windows Server 2012
Hyper-V, has sharpened the focus of data center management on
increasing virtual machine (VM) density and virtualizing Tier-1
application workloads to maximize their virtualization ROI.
The average number of VMs per
server in my environment:
This technology examines the ability of Cisco UCS and HP
BladeSystems to provide useable I/O bandwidth and I/O flexibility
that are needed to support the growth of VM density and
heterogeneous workloads.
VM Density Driving Need for Useable I/O Bandwidth
IT Brand Pulse surveys indicate that IT pros project VM density will
almost double from 13 VMs/server to 24 VMs/server within the
next 24 months—driving a need for more useable
I/O bandwidth.
Heterogeneous Workloads Driving Need for Flexibility
More VMs/server means more diversity in the applications the
server I/O system must support. This drives the need for flexibility
in how blade server I/O bandwidth and policies are provisioned to
different applications.
What I need most to increase
the density of VMs per physical
servers is more:
Converged Infrastructures Demand I/O Flexibility
The convergence of compute, storage and networking into a
shared resource pool is gaining acceptance and deployment in
enterprise data centers. By definition, this sharing of resources by
multiple applications and lines of business is also driving the need
to have a flexible, high throughput and low latency blade
enclosure I/O.
41.1%
41.1% of IT professionals surveyed said “server virtualization” was the
application most driving the adoption of 10GbE in their data center.

3. Anatomy of Blade Server Chassis I/O
Application Performance Depends on a Healthy Network
Every blade server chassis has an entire network embedded inside to carry east-west traffic between servers,
and north-south traffic to top-of-rack, end-of-row, and core switches upstream. The I/O performance of
heterogeneous applications running on virtualized blade servers can differ significantly based on:
The ability of some blade server networks to scale without over-subscription

4. Useable I/O Bandwidth
Oversubscription Reduces Available Bandwidth
Oversubscription occurs when the I/O capacity of the adapter ports connected to a switch port exceeds the
capacity of the switch port. The oversubscription ratio is the sum of the capacity of the adapter ports divided
by the capacity of the switch port.
Oversubscription also results from the imbalance between outgoing bandwidth and incoming bandwidth
available from a blade server chassis to top-of-rack, end-of-row and core switches. Severe oversubscription
reduces useable bandwidth, increases network latency, slows user response time, and makes it difficult to
deliver deterministic application performance.
Blade server designers maximize useable bandwidth and minimize oversubscription. Not all blade server
architectures are optimized for these considerations.
Multi-Tiered Networks Increase Applications Latency
As data traverses a network fabric, each network tier in the path adds delays, negatively impacting
applications performance. As a result, designers also architect for minimal tiering to reduce these latencies.
Cisco UCS Hierarchical Network Architecture
The Cisco UCS design supports 8 blade servers per chassis and defaults to a hierarchical, multi-tiered, “northsouth” networking architecture in Cisco’s preferred End Host Mode. This mode is enabled by creating a
logical system where server-to-server traffic for hosts in the same fabric, travels outside the chassis to the
Fabric Interconnect.
This mode requires two fabric interconnects and two fabric extenders — with each extender providing up to
160Gb/s of total bandwidth for on active-active configuration. A fully loaded blade with a VIC 1240 quad-port
10GbE adapter plus a quad-port mezzanine extender requires 80Gb/s for a total of 640Gb/s with an 8 blade
enclosure—resulting in up to 4:1 oversubscription and reduced available bandwidth.
Oversubscription is exacerbated when the servers are on different fabrics, requiring server-to-server traffic to
travel north of the Fabric interconnects to the end of row aggregation switch. This architecture prevents
network loops but also prevents server-to-server traffic flow between interconnects, instead forcing it to
travel all the way to the end of row switch—resulting in the fabric interconnects become a north-south
bottleneck and up to 10:1 oversubscription, significantly limiting useable I/O bandwidth.
Oversubscription
Document # APP2013011 v16 August, 2013
The ratio of the switching bandwidth to the aggregate
bandwidth of all ingress (incoming) ports. High ratios
can result in latency and reduce scalability.

5. Applications Latency
Cisco UCS Network Architecture Latency
The scenarios described also illustrate the additional network tiers elements built into the UCS architecture
which can result in increasing total latency with a commensurate reduction in applications performance and
unpredictable applications behavior. A calculation of network latency is examined in greater detail later in
this report.

6. HP ProLiant Gen8 Blade Server
The Ultimate in Useable Bandwidth
HP ProLiant Gen8 blade servers offer the flexibility of network architectures optimized for server-to-server
“east-west” traffic or “north-south” traffic in/outbound from the blade enclosure. This is accomplished via
configuration options for the HP FlexFabric server network adapters and HP Virtual Connect FlexFabric
modules.
If the application places demands for server-to-server “east-west” traffic within the enclosure, an activestandby configuration is utilized with the upstream network switch connected to a single port on each HP
Virtual Connect FlexFabric module. However, if the application demands predominantly server-to-core
“north-south” traffic, an active-active configuration enables two uplink ports on the network switch,
increasing overall bandwidth and reducing oversubscription.
A c7000 enclosure with 16 blades, each with two 10GbE FlexFabric adapters and two mezzanine 10GbE
adapters requires 960Gb/sec total bandwidth. The enclosure’s available internal mid plane bandwidth of
7.2Tb/sec, about 7x the required bandwidth – results in zero oversubscription for east-west traffic flow.
For traditional north-south traffic, HP Virtual Connect FlexFabric modules with 16 downlink and 8 uplink ports
results in 2:1 oversubscription, similar or lower than Cisco’s, depending on configurations.
The 7.2 Tb/s useable bandwidth between device bays and interconnect bays allows server-to-server traffic to stay
within a single c7000 enclosure

Network Latency Comparison
The HP Virtual Connect FlexFabric architecture flexibly supports both single and separate fabric traffic pattern
implementations. However, configurations architected with separate fabrics address the enterprise
requirements for resiliency through redundancy.
The HP solution delivers lower latencies for both configurations, based on the calculations from
specifications provided by HP and Cisco.

8. I/O Flexibility
Support for Only One Network Wire Reduces I/O Flexibility
Based on IT Brand Pulse surveys, 40% of IT organizations are not converging with FCoE. For the 40% of IT
professionals who have been too busy to look at FCoE, or who say they have no plans to converge their LANs
and SANs, parallel Ethernet and Fibre Channel infrastructure will be deployed.
The modular design of blade servers make them inherently flexible. But not all blade server platforms are
equal when it comes to hosting multiple heterogeneous virtualized workloads and delivering I/O flexibility.
While some blade server designs accommodate Ethernet and native Fibre Channel connectivity, the Cisco
UCS design only supports Ethernet connectivity.
Wanted: Parallel Ethernet & Fibre Channel Networks
in 2013, the prevalent data center network architecture remains a parallel network architecture, including a mix of specialized NIC, iSCSI, and
Fibre Channel host adapters, as well as Ethernet and Fibre Channel switched fabrics. Cisco UCS blade servers support only Ethernet
connectivity. Adoption of FCoE technology is required to access installed Fibre Channel resources.

10. Fibre Channel without Switches
Direct Attached Storage Reduces CAPEX and OPEX
Complementing the HP ProLiant blade server’s flexibility of Fibre Channel (FC) connectivity capability, HP’s
Flat SAN technology enables enterprise class direct attached storage to HP 3PAR Storage Systems without
requiring a Storage Area Network (SAN) fabric. This scalable solution provides connectivity for up to 192 FC
ports and 192 Petabytes of storage capacity. Benefits of this architecture include:
Reduced CAPEX on SAN fabric switches and associated software licenses
Reduced ongoing management and support OPEX of multiple touch points
Latency reduction of up to 55% by removing the fabric switching layer
Up to 2.5x faster Fibre Channel storage provisioning
These benefits accrue while maintaining the flexibility to simultaneously include fabric-attached storage for
traditional SAN connectivity from the same Virtual Connect module.
