Server and Client Requirements. The computing model for thin client networking means that the horsepower is concentrated on the server end, not the client end. Because the server will be supporting dozens of people maybe hundreds this is not the time to skimp on power. Server Hardware. The notion of using a bigger server so that you can skimp on client side hardware isnt new. Thats all a file server is a computer running a big, fast hard disk so that you dont have to buy big, fast hard disks for everyone in the office. RDS servers are designed on a similar principle if most of the processing takes place in a single location, you can concentrate the hardware resources needed to support that processing in a single location and worry less about power on the client end. Use a Powerful RD Session Host Server. Since an RD Session Host server will be serving applications or full desktops to clients, youll need to purchase or build a powerful server. Processing power and RAM are the most important resources. Depending on the types and number sessions youre supporting, you may also want to consider boosting disk access and network bandwidth. On the surface, calculating the needs seems straightforward. Just follow these steps Calculate the resources needed for the operating system. Calculate the resources needed for a small number of sessions such as five. Download Naruto Ova 8 Sub Indo Film. Multiply the resources needed for your sessions based on the total number of sessions you plan to support. If you planned to support 1. Add the total session resources needed for sessions to the resources needed for the operating system. Although this seems like simple math, it never seems to work out that way. Synergy is often hard to predict. Synergy where the whole is greater than the sum of its parts often results in something unexpected. Additionally, if the deployment is successful and users are happy with what they can do, they may end up using it much more than you anticipated. You dont need to tell this to the budget people, but its best to add a buffer for the unknowns and to plan for expansion. Additionally, you should do some independent research on Remote Desktop Services, starting with Microsoft. Core Hardware Resources. For the purposes of running an efficient RD Session Host server, the bare minimum required to run Server 2. R2 wont cut it. Although there are no hard and fast specifications for an RDS server, some general guidelines for server sizing follow Processor Faster is better to a point. More important than a fast processor is one with enough cache so that it doesnt have to reach out to the slower system memory for code and data. Faced with a choice between more cache and more speed, go with more cache. Most RDS servers these days have multiple processors, and these processors have multiple cores. Although only multithreaded applications will actually use more than one processor at a time, if there are multiple processors, then threads needing execution can line up at both. Memory RDS servers tend to be memory bound, not processor bound. Get high speed, error correcting memory get plenty of it and be prepared to add more as you add more users or applications to the RDS server. The amount of memory youll need depends on the applications that people use, the number of concurrent sessions, and the memory demands of the files opened in those sessions computer aided design CAD programs will stress the system more than, say, Notepad. Thankfully, the 6. GB limit. Start your calculations with at least 8. GB of RAM for the server, and start adding based on the of number of users and memory required by the applications theyll run on the server. Windows Server 2. R2 will support up to 2. TB of RAM. Disk Consider Serial Computer System Interface SCSI disks on an RDS server if at all possible. A SCSI disk controller can multitask among all the devices in the SCSI chain. Most people believe that SCSI performs much better both Serial Advanced Technology Attachment SATA and Enhanced Integrated Drive Electronics EIDE disks, though some people are starting to find that high end SATA solutions perform better than low end SCSI solutions. Disk performance is an important capability in any server, especially so in an RDS server. Additionally, consider a Redundant Array of Inexpensive Disks RAID solution to increase the performance andor fault tolerance of the drives. For a high end RDS server, a RAID 10 solution provides both performance gains and redundancy. Network On a busy RDS server, consider load balancing high speed network cards, which can assign multiple NICs to the same IP address and thus split the load of network traffic. Another alternative is a multihomed server with one NIC dedicated to RDS session traffic. As far as network speed goes, sending application output and client side input back and forth requires little bandwidth, but client print jobs sent to mapped printers can take quite a bit of bandwidth. Mapped drives may also increase the load by making it possible to copy files back and forth across the RDP connection. Using the Performance Monitor. The Performance Monitor discussed in Chapter 1. RDS sessions are stressing the server. Server load should scale closely with the number of people using the server therefore, as long as you pick a representative group of about five people, you should be able to extrapolate your needs for larger groups. The key objects and counters for measuring general server stress introduced in that chapter will help you size your RDS servers. But a couple of Performance Monitor objects are worth examining to give you detailed information for your RDS server. Performance Monitor Objects Still Called Terminal Services. Although the name of Terminal Services has changed to Remote Desktop Services in Windows Server 2. R2, its still called Terminal Services in Performance Monitor. It might look like a typo, but the two objects are called Terminal Services and Terminal Services Session. First, the Terminal Services object has counters representing the number of active sessions sessions where the user has connected to the RD Session Host server and successfully logged on, inactive sessions where the user is still logged onto the RDS server but has stopped using the session, and the total combined. Besides simply monitoring activity, you could use this to alert you when the number of active session reaches a certain threshold. Say you wanted to know when a server hosts more than 1. You could do this with a data collector set. Chapter 1. 7 discussed data collector sets in more depth, but its possible to set up a simple user defined data collector set with an alert.
