Why server is needed in smb

  1. 1. WHY IS SERVER SO ESSENTIAL FOR THE GROWTH OF SMALLAND MEDIUM BUSINESSES?SMB Current Scenario of Small and Medium Sized BusinessesIn the present Challenging Time it’s not easy trying to operate a small to medium-sizedbusiness (SMB). The economy is still struggling, competition is fierce, and already-stretchedbudgets must be cut even further to weather the storm. As a consequence, small tomedium-size businesses (SMBs) are re-evaluating where and how they spend money, howthey drive revenues. In the process they neglect the importance of how IT supports thesegoals.Many small and medium businesses (SMBs) don’t have a dedicated IT department. At best,they have maybe one or two people who handle IT. Yet, their IT demands are similar tomany large enterprises. Business even for SMBs is a 24/7 proposition. Many employeeswant 24/7 access to e-mail, files, and applications. And that need for around-the-clockavailability is also being driven by the global extent of the Internet – any company with aWeb site and a product or service to sell online must have be able to accommodateCustomers on their time frame. These contrary conditions that are being faced by manySMBs —little or no IT staff and growing IT demands—mean that they need reliable ITequipment that is easy to manage. Unfortunately, as the economy has worsened, SMBshave fallen behind in adoption of IT solutions that have the potential to cut costs andposition their companies for growth.Based on user surveys, the IT Effectiveness Index1 found that nearly one in four SMBsreceived a “failing grade” in IT effectiveness. These companies reported a high level ofdowntime, a lack of security, and the absence of disaster recovery programs. About 37percent of SMBs received a “C” grade, which indicates they are just barely getting by.JAIDEEP KUMAR Page 1+91-9559523999/
  2. 2. Where is the real Problem?Almost every startup business uses computers. And as your new business grows, addingDesktop, Laptops, PDAs and other communication or data devices is almost inevitable.Before you know it, you may reach a point where your computing infrastructure seemsdisorganized.Whether you know it or not, the minute you add a second computer to the original one youused to start a business, you’ve created a “peer-to-peer” computing environment in whichseparate machines perform many of the same computing functions in a decentralized way.It is surprising that the majority of companies never bother implementing a client/serverbased network. Instead they just continued adding on workstations to their old peer-to-peernetwork.Peer-to-peer networks dont provide you with much in the way of security and resourcesharing. PCs networked in a peer-to-peer fashion are adequate when you only have a fewusers on the network, but once you have more than 5 or 6 users on your network, then youreally start facing the problem. You’ll notice you’re getting tired of the lack of datacoordination among your employees and the huge inefficiencies that that implies. You’ll wishyou could pull up that important file from your Agra based office while you’re road-warrioring your way through sales calls in Lucknow. You’ll reel from the occasionaldisastrous loss of data that hasn’t been backed up and the frustrations of everyone on yourteam in trying to recover.“It boils down to the pain points that a small business might be facing.”What can we do?If that sounds familiar, it may be time for you to purchase a “server” – one machine thatcan “serve” the information needs of all of your computers from a central source, ensuringthat all of your employees and all of your applications are working in sweet concert insteadof haphazard isolation. For several thousands to a few lacks Rupees, a server instantlyprovides many benefits that make the investment more than worthwhile.A server is a single computer whose purpose is to be the master administrator and router ofall of your company’s computing needs. Any type of software or data that benefits fromJAIDEEP KUMAR Page 2+91-9559523999/
  3. 3. coordination and protection is stored on - and dispensed by - the server to your othercomputers, which become networked together because they’re all tied into the server. Itsoperation requires specific server software, such as Microsoft’s Small Business Server 2008.Customer data can be updated by anyone on a computer linked to your company’s server,and when they access it, they can be sure it’s up to date. Your team can update and shareWord documents, PowerPoint presentations, or Excel spreadsheets in the same way using aserver. No matter where you are physically, your computer can communicate not only withthe “home office”, but with individual employees through your server. To keep out threatsand unwanted emails, you can apply anti-virus or anti-spam software via the server and itwill clean and protect the data flowing to and from all of your computers.And you can use your server as the Company’s IT-Security gateway, setting it to regulatevarious levels of access to your data and your computers for people both inside and outsidethe company. Some entrepreneurs even use their servers to host their websites; but ifyou’ve got a decent amount of traffic to your site, that’s probably something you want tocontract out to a specialist.You can actually purchase a low-end server for as little as Rs. 50,000. But, typically, youcan expect to pay from Rs. 90,000 to Rs. 120,000.00 for a server that will meet the needsof a startup with one to dozens of employees, including the server software needed to runthe server.According to PC World, SMBs can and should use servers for centralized file management,printer sharing, shared storage, automated backup, Web site design, communications, andeven Web hosting. Today’s powerful and expandable servers enable SMBs to create a solidand versatile computing infrastructure, and this leads to benefits such as:Server Benefits#1 File and Network securityThe most important role of a file server is the network security it provides. By creatingindividual user and group accounts, rights can be assigned to the data stored on thenetwork preventing unauthorized users from accessing materials they shouldnt be viewing.JAIDEEP KUMAR Page 3+91-9559523999/
  4. 4. For example, the sales team doesn’t need access to employee personal records whichshould only be accessible by HR.#2 Increase reliability; decreased workflow interruptionsMany servers are equipped with redundant power supplies. With a secondary power supplyrunning in tandem, the loss of one of the power supplies doesnt affect normal systemoperations. The same goes for a servers storage system. Unlike an average desktop PC thatuses a single hard drive, a server will typically use multiple hard drives working ina RAID configuration to prevent data loss or an interruption in workflow. In addition, manyservers are also equipped with Hot Plug hard drives and power supplies. These Hot Plugcomponents allow you to replace faulty hardware without interrupting the entire office. Inaddition, since all employee data is being stored on the network, if a users workstation failsmid-workday, employees can access the same files from another workstation.#3 Centralized data storage and shared resourcesWith a network server, all of the users on the network can make use of various networkresources right from their desks, increasing efficiently. Some of these resources include thefollowing:- Centralized data storage (RAID Array)- Network Attached Storage (NAS) Devices- CD/DVD Towers- Printers and Fax servers#4 Virus ManagementOne of the greatest threats to your network is the possibility of infection from viruses,spyware and spam. So having good, updated, anti-virus software installed on your systemsis a necessity. In an office of 10 people or less, systems can be maintained individually.Anything more than that, though, can become a real burden. In those circumstances, ananti-virus package that combines workstation and server virus protection into a singlesolution makes more sense.JAIDEEP KUMAR Page 4+91-9559523999/
  5. 5. #5 Centralized BackupAll businesses should backup their data on a regular basis. By having all of your companyand employee data stored in one location, backups can be performed reliably and quickly.So youll never need to worry about what data is stored on what workstation as you do in apeer-to-peer network. Today, almost any media type can be used for backup purposes. Inaddition to the traditional tape drive, HP RDX Storage, CDs, DVDs, removal storage andeven Network Attached Storage (NAS) devices are acceptable. Your choice of media willdepend on your specific backup requirements. Depending on your budget and your dataretention needs, any of these would be an acceptable solution. Make sure you have at leasta scheduled weekly backup, although a daily would be better.Why Entry Level Server is better than High End Desktop?Does your business have more than 5 employees? If your answer is “Yes,” then yourbusiness should be using a server network. If you dont already have a server in yourbusiness, youre probably already using a desktop system as a server of sorts. Maybe itcontrols some files or printers that you can share with other PCs, but there are keydifferences between servers and desktops, and many good reasons to invest in a server foryour small business. Many people are under the misconception that a server is no differentfrom a typical desktop PC. This couldnt be further from the truth. While almost any PC thatmeets the minimum hardware requirements can run the server operating system, thatdoesnt make it a true server. The technologies behind them are engineered for differentpurposes. First and foremost, you need to understand these key differences betweenservers and desktop computers.A desktop system is optimized to run a user-friendly operating system, desktopapplications, and facilitate other desktop oriented tasks. Even if the desktop had similarprocessor speeds, memory and storage capacity, it still isnt a replacement for a real server.The technologies behind them are engineered for different purposes. A server is engineeredto manage, store, send and process data, 24 hours a day, 7 days a week, 356 days a year.For these reasons, servers need to be far more reliable than their desktop counterparts. InJAIDEEP KUMAR Page 5+91-9559523999/
  6. 6. order to accomplish this, servers offer a variety of features not typically found in a desktopPC.So lets look at some of those differences. On the surface, they seem very similar. Bothhave a CPU, RAM, and hard drives for storage. Servers, however, are designed withheavy-duty back-end tasks in mind, and arent well equipped to run normal desktopworkloads, such as graphics-intensive applications. Servers excel at running servicessupporting those desktop applications, such as databases.Superiority of Server over Desktop PC:1. Performance- Can process data faster and more efficiently2. Scalability - to meet current, as well as future needs3. Reliability - Redundant & Hot Plug Components4. Manageability-Reduced Administration, More Secure & Long term cost saving#1. Performance -Can process data faster and more efficientlyThe CPU in an entry-level server isnt all that different from a midlevel desktop, but doesdiffer in some ways, such as it is packed with new and enhanced technologies as well, suchas an integrated memory controller, a three-level cache hierarchy, Intel® Hyper-ThreadingTechnology, Intel® Turbo Boost Technology, and Dynamic Power Management.Like modern desktop systems, server CPUs can have multiple cores, although theygenerally make better use of multiple cores than desktop systems will. Multiple-core CPUsare basically a single CPU that contains two or more processing cores. In essence, it’s likehaving several CPUs on a single chip. Using multi-core CPUs can greatly increase theprocessing power of the system and lengthen the usable life of your server. Someentry-level servers, such as an Intel Xeon E3-1220, also have a Quad-core CPUs. For anoffice of 10-40 users, this is generally sufficient. Be aware, though, that a few extra Rupeesinvested now in on a higher-powered server -- say a dual-socket server can be greatlybeneficial as your business grows. Overestimating your needs now might be your best bet.To put it simply, CPU CACHE is a small, dedicated pool of RAM that the CPU can use to storefrequently requested data. If the cache is larger, the CPU appears faster because it canJAIDEEP KUMAR Page 6+91-9559523999/
  7. 7. store more data in the cache for faster recall. Server CPUs generally have larger and morevaried caches than desktop systems for just this reason.INTEL TURBO BOOST TECHNOLOGY gives an administrator the option to manually orautomatically turn off individual cores and run the remaining cores faster than their nominalfrequency (if there is power and thermal headroom to do so). This provides the flexibility torun in an energy-conserving mode during normal times, while allowing the servers tothrottle up during peak workloads. Dynamic Power Management works hand-in-hand withIntel Turbo Boost Technology to automatically optimize the performance and power use ofthe processor, chipset, and memory based on business requirements.In essence, Dynamic Power Management allows the New Intel Xeon processor to providegreater performance using the same amount of power as previous-generation Intelprocessors, or achieve performance equivalent to previous-generation processors using lesspower.Servers also generally have very FAST RAM, which is quite important for performance. Sinceservers are running many different tasks simultaneously, fast RAM and a fast system busare crucial to maintain smooth operation. ECC, or error‐correcting, RAM is also a feature ofmost server-class systems. ECC helps protect the integrity of the data stored in RAM duringnormal processing. It costs a bit more than non-ECC RAM, but in a server system, it’sgenerally a requirement.The disks in servers are also generally different than those in desktops. Theres more tohard drive than just size -- the speed at which the platters within the drive spin can greatlyaffect performance of the entire server. Hard drives running at 10,000 RPM can deliver datafaster than slower drives running at 5,400 RPM, especially under load. There are severaldifferent types of hard drives as well, such as SATA and SAS drives. For most entry-levelservers, 7,200 RPM SATA drives configured in a RAID1 or RAID 0 arrays will be sufficient.For higher performance, you may want to consider SAS drives. Generally,higher-performance disks are necessary only if the server will be running heavierapplications, such as a large database.For connecting to the network, most servers have at least one GIGABIT NETWORKINTERFACE (the piece of hardware that talks to the network). These interfaces are differentthan the network cards in desktops since they perform certain network functions byJAIDEEP KUMAR Page 7+91-9559523999/
  8. 8. themselves, relieving the servers CPU to handle more complex tasks. The end result is thatthey can push more data under load than normal network interfaces. If multiple interfacesare in the server, they can even be bonded together to provide greater bandwidth.For the most part, servers in small-business settings are designed to run a large number ofdifferent services and applications to support a small number of users. Products likeMicrosofts Small Business Server are designed to do just that. They offer many differentfunctions that can run on a single dedicated server, but they can support only a relativelysmall number of users. In many small business environments, this is all thats necessary.And theres one more bit of good news: These days, entry‐level servers are available fornearly the same cost as midlevel desktops, making them a natural for small businesses.#2. Scalability - to meet current, as well as future needsWhile a high-end personal computer may meet the existing needs of a smaller business,theres a high probability that it wont be able to keep up as the company expands and itsnetwork needs increase.Servers are designed with scalability in mind, so as your business grows your server willhave little trouble supporting increases of data, users and network traffic. Some Serversare Dual Processor and some multi Processor capable so that if required it can be upgraded,reducing the extra cost incurred in purchasing new hardware. The Memory and Storagespace can also be dramatically increased to withstand the future expandability requirement.It is possible due to the more numbers of DIMM Slots and RAID Technology which is missingin any Desktop & Laptop. Network Interface can also be added due to availability of morenumbers of PCI Slots present on the Server enabling it the number of user expansion.Servers are designed to meet a wide array of needs and accommodate nearly any numberof users. While a servers flexibility and scalability are two of its biggest selling points, thedownside to this is that it makes it extremely difficult to provide a simple, precise answer tothe question of how much memory and storage space will be needed when implementing anew server. Each case needs to be researched based on a number of factors, most notably:- How will the server be used- How many users will the server need to accommodate, both now and in the future- The types of demands users will be placing on the server, both now and in the futureJAIDEEP KUMAR Page 8+91-9559523999/
  9. 9. The correlation between the number of users a server will be supporting and the amount ofmemory needed is very high. As a result, the amount of memory in a server directlyimpacts the number of concurrent users that it can support, as well as the number ofapplications the users can concurrently use to interact with the server. An importantconsideration, though, is the maximum amount of RAM the servers operating system canutilize. As an example, the standard editions of Windows Server, including Windows Server2008, can only support a maximum of 4 GB of RAM, whereas the enterprise and datacentereditions can scale from 32 GB up to 2 TB, depending on the specific version of WindowsServer used.When it comes to storage space, many organizations initially gauge their servers amount ofstorage based on the number of users the server is expected to accommodate, but thecorrelation between storage space and users isnt as high as the memory side of theequation. A more important gauge of how much storage is needed involves the types ofdemands users are expected to place on the server. What your users will be accessing onthe server and working with will determine how much memory and storage you can expecteach user to need.In terms of storage, disk quotas can be applied to track and control each individual usersdisk space, helping to prevent the server from filling to capacity without warning. Quotascan also be applied on a per-user basis if some users have needs that necessitate additionalstorage space. As an example, if a file server has a limit of 250 MB per user but you findthat some users need to exceed that limit, these users can be provided with higher limits(500 MB or 1 GB, for example). The key is to set quotas that will allow you to accommodateyour initial number of users and their needs while retaining enough unused storage space toaccommodate user growth or evolving data storage needs. And as mentioned earlier,additional storage space and memory can be added to a server fairly easily andinexpensively in most cases without needing to replace the server.#3. Reliability - Redundant & Hot Plug ComponentRedundancy is particularly important for storage, where RAID (redundant array ofinexpensive disks) is typically utilized to keep a server up and running even if a hard driveJAIDEEP KUMAR Page 9+91-9559523999/
  10. 10. crashes, as well as for power, where backup power sources are utilized to keep a serveroperational even if the main power supply goes down. These components and otherhardware in a server can typically be replaced with minimal or no disruption withoutshutting down the Server to users with Hot Plug Component.By adding a server even an entry level server to your network, you can benefit greatly fromthese features, especially considering the data protection available in a RAID array. One ofthe major hardware differences between servers and Desktop is the disk subsystem. Whiledesktops have a single hard drive, servers generally have several hard drives configured toappear as a single disk. This is called RAID, or Redundant Array of Inexpensive Disks. RAIDis widely used to protect servers from individual disk failures, critical when your business isat stake. If a drive in a RAID array fails, it does not mean that the data contained on thatdrive is lost, since other drives in the array still contain the data. There are multiple levelsof RAID, but for entry-level servers, RAID levels 1 and 5 are the most common.RAID level 1 is a simple mirror of two hard drives. The data stored on a RAID 1 array existson both drives at all times. If one drive fails, the other drive still has a complete copy of thedata, and the server can continue to function. RAID 5 is more complex, involving at leastthree drives, and the setup can survive the failure of any one drive. Either option willprotect against failures, but RAID 5 delivers more available disk space than RAID 1 and isfaster as well. This data protection is crucial to a server, and any server you add should beequipped with a RAID controller and a RAID array. Make sure a hardware-based RAIDcontroller is in the server as well, not just a software-based one -- software-based RAIDworks, but can be more problematic for the uninitiated, since there isn’t a dedicatedcontroller managing the hard drives. If you’re using software RAID only, you may run intodifficulty in the event of a disk failure, especially if you’re not an expert at software RAIDrecovery procedures.Another feature of most servers is REDUNDANT POWER SUPPLIES. This means that theserver has at least two power supplies that both draw power during normal operation. If onepower supply fails, or power is cut to that supply, the server continues to function. Not allservers have this feature, but some offer the option of adding another power supply lateron. As with any computer, you should add a UPS (Uninterruptible Power Supply) to protectyour server from power surges and outages.JAIDEEP KUMAR Page 10+91-9559523999/
  11. 11. Some entry-level servers offer Hot-Plug hard drives and Power Supply, while others do not.Hot-Plug drives enable a hard drive & Power Supply to be replaced without shutting theserver down or even opening the case. If a disk fails or any of the Power Supply fails it canbe pulled out of the running server and replaced. When the disk is replaced, the RAIDcontroller will then rebuild the RAID array to ensure that the data is protected. If the serverdoes not have hot-Plug component, then the server must be shutdown, opened, and thefailed component is replaced inside the system.#4. Manageability-Reduced Administration, More Secure & Long term cost savingWhen you’re setting up the Servers, Server’s Onboard Administrator software deliversmanagement features that simplify server configuration, health and performancemonitoring, power and thermal control, and remote administration. It also includes SSLsecurity, detailed server status updates, event logs for investigating and remediatingincidents, alert forwarding to ensure that the right person learns of specific events, virtualindicators, diagnostics, and power capping to ensure that thresholds are not exceeded.Onboard Administrator functions without additional software and can be accessed locally orremotely, supporting in-house or off-site management seamlessly.With Insight Control, your business will enjoy a 12-fold increase in server deploymentspeed, a 77 percent reduction in unplanned downtime, reduced administrative expenseswith remote management capabilities, and the ability to increase capacity and expand theserver without causing additional headache or delay. Further, those who want a helpinghand can turn to HP Insight Remote Support, which enhances HP SIM’s event-monitoringcapabilities by sending automatic hardware event notification securely to HP. In manycases, this can help companies avoid or fix problems before they escalate into failures,which is a tremendous benefit for a number of reasons. First, your computing systems aremore reliable and less prone to unplanned downtime. Second, this tight monitoring andcontrol is provided by HP, which relieves a significant amount of the maintenance burdenfrom an already-stretched SMB IT staff. Remote support reduces IT overhead and thussaves time and money. This remote support is free with a valid warranty HP Care Pack.An integrated health monitor ensures that your server is running optimally and helpsprevent problems before they disrupt service. Insight Control detects, analyzes, andJAIDEEP KUMAR Page 11+91-9559523999/
  12. 12. explains hardware bottlenecks on HP ProLiant servers, notifies admins if a bottleneck seemsto be building, and debugs performance issues. It logs data and provides a playback tool tohelp IT staff visualize incidents as they happened, which helps in after-hours problem-solving. Insight Control also pinpoints the exact component that is causing performanceissues, with an explanation of the issues, so you can repair or replace accurately and extendthe life of your server.While you can certainly expect a higher up-front cost when investing in a server as opposedto utilizing an existing high-end desktop, over the long run youre likely to see a lower totalcost of ownership with a server for several reasons. First, with your server serving as acentral resource controller there will be fewer components to have to support in terms ofadministration and maintenance. Additionally, with servers being designed to allow manyusers to share applications and connections to the Internet and wide area networks (WANs),a high-end server can reduce the need for duplication of hardware as well as additionalcomputers in many cases.Beyond the purchase price, an SMB solution appropriate for today’s business environmentmust also have a low operating cost. Here, there are two areas that must be addressed toachieve the best results. First, the solution must be easy to manage. Over the life of aserver, the cost for a person’s time and labor needed for server administration andmanagement can be substantial. In most cases, the management costs dwarf the purchaseprice of the server itself. The easier a server is to manage, the lower this cost will be. Betterstill, servers with built-in monitoring tools can help detect potential problems before theyimpact a server’s availability or performance. For instance, noting that storage space ispreciously low, and IT manager might offload some files to an archival storage systembefore an application gets an error message when writing data to a server disk drive.Without this ability to detect potential problems before they occur, a server might crash andsomeone would have to spend possibly many hours troubleshooting to figure out why aserver has crashed. With a solid management and monitoring system in place, a managerwould have the luxury of taking preventive measures to ward off downtime. A secondoperational cost area that requires attention today is the consumption of electricity. Eachgeneration of IT equipment, in general, and servers, in particular, has consumed more andmore power.JAIDEEP KUMAR Page 12+91-9559523999/
  13. 13. RACK VS. TOWEREntry-level servers are generally available in either a rack-mount or tower form. If this is thefirst server for the company, you probably won’t have a suitable server rack already inplace, and for a single server, adding that rack may not be cost- effective. Thus, a towerserver is likely to be the best option.Many tower servers can later be converted to rack-mount servers with the appropriateconversion kit, so if your infrastructure grows to the point where a rack is required, yourexisting investment can be modified to fit your needs.A tower server is generally only slightly larger than a regular desktop system, and can beplaced under a desk or in an area that has little traffic. Make sure that there’s adequateventilation and climate control wherever you place the server. Though it’s a good idea toalso have a monitor, keyboard, and mouse hooked up to the server, doesn’t be tempted touse the server as a desktop system.Wrapping It UpFor the small business owner, adding a server to your network doesn’t need to be adaunting task.Stress on your computing infrastructure is usually a blessing that comes from growth. Andto make sure nothing gets in the way of that growth, you’ll likely want to buy a server. Itmight be one of the best things you can do right now to streamline your operations and setthe stage for future success. Servers are the unsung heroes of the corporate computingenvironment, working behind the scenes to help get the maximum benefit from the personalcomputers that people should implement.For any consultant regarding your IT Infrastructure Designing, Optimization or up-gradation you can kindly contact the undersigned.JAIDEEP KUMAR Page 13+91-9559523999/
