HW & SW Requirements for new DCS system
While commissioning a new DCS system, on what basis the Server is chosen. I mean type of Server(Tower, Rack type). What Should be the minimum hardware requirement for a machine to be functionally working as Server and what should be the hardware requirements
for a Workstation?
AC800M PM856 controller (1 ÇI854 & 5 CI801, Each CI801 having 10 DI/DO/AI/AO)
Non Critical Application
As of now we have proposed 1ACS+ 2 Workstation
64 bit Windows 2008 R2 Server- For Server & Windows 7 for Workstation
800xA5.1 Rev D
Pls Suggest how to choose the correct Hardware and correct/suggest any software changes. I'm eager to know on what basis they are selected. I know that on order, ABB will take care of the above said doubts, but I would like to know personally
Thanks in advance

Virtualize it !!!
Buying individual servers for connectivity, aspect etc has become pointless and expensive. You can save a significant money and give yourself much more flexibility by running redundant virtual servers. You only need to buy 2 physical machines which you can easily expand with disks and memory as required if your system turns out not to be powerfull enough.
The PC hardware requirements for clients have always been relatively light. 4 GB memory will run fine. xA software is typically not limited by the CPU. The 2 things you need for good performance of an xA system is fast disks in the servers and a gigabit network backbone. ( I havent seen a site running SSD's yet, but im willing to bet they would work very well on history and the aspect servers which as re quite disk intensive )
4 Gb memory is also enough for the servers. 800xA is not really a 64 bit application and many components cannot make use of the full memory yet - this will almost certainly change in version 6. But if your servers are virtualized, adding more memory from the pool takes a couple of minutes.
Any future expansions will also likely be much easier if you install xA on win 64 bit. There is no upgrade path from win 32 to win 64 without reintalling the OS entirely, so use win64 even if you are not currently using more than 4GB of memory.
The detailed specs of what is required for each version are in the product guides and the installation manuals. These change occasionally and you need to read them and make decisions based on the latest info. But using virtual machines with VMware will save you time, effort and money. IMHO you would be mad not to.
Your order will be validated using an "800xA wizard". This is an internal and tech partner tool that validates all your components and bill of materials. It will check all of your AC800 controller and IO rquirements etc. (Its a pretty good tool)
There are documents available as for example:(3bua000500_o_en_system_800xa_5.1__5.0__4.1_third_party_software)
which recommend tested hardware (server, PCs, etc) and also recommend what are the different needs according to different types of nodes (AS, CS, IM, etc)
I would suggest you have a look into these documents which I guess clearly give a clear idea of what are the minimum HW requirements.
Virtualization is also supported, but regarding the new strategy of windows 8.1 (with regard to server roles) I think the answer to virtualize is not always so obvious and the right decision, it implies more IT knowledge and also other IT challenges.
Hence, according to your needs yo can define your minimum HW requirements and then decide if you wish to virtualize or not as 800xA supports this option aswell.
