Purchasing a Web Service Server for Business Web Services

jwilder · 2010-04-02

We are currently connecting our web site to NAV via web services (3 tier). We are in the process of pruchasing a server that will house the Service Tier Service (the machne running the Web Service Service). In regards to Processor, Memory and Drives where should we spend most of our money?

My guess is the drives (they will be SAS drives) are less important but the processor and memory are much more important. Obviously if this were our Database Server drives would be equally if not more important.

We are thinking of a Dell PowerEdge R610 2 quad core processors (E5520 2.26gb) with 12GB memory. We will install Windows Server 2008 64bit.

Remember we could have up to 40 connections from our website hitting this at once (though unlikely). We also may have a few other internal apps running periodically through web serveces. Will this suffice?

The service tier hardly uses any harddrive, unless you include virtual memory.
The service tier is very cpu incentive and uses max of 4 gig of ram.
I suggest to use two service tiers on same box and use round robin method to connect to the service tiers so that connection are evenly spread between the two services tiers.

Service tier has a 4gb limit? Even on a 64bit operating system?

Yes. The service tier is compiled in 32 bits. in 64 bit OS it runs on WOW

One more question. Are we better getting a server with 2 - 2.30ghz processors or one 2.8ghz? Do NAV Web Services take advantage of multiple processors?

Is the 2.8 ghz processor a multicore processor?

I suggest to ask that for the vendor. There are many processors with varied amount of cache that is shared differently.

Both processors are quad core.

If understand it correctly you want to know which one would be better.

2 - 2.30ghz Quad processors or one 2.8ghz Quad Processor?

I would go with 2 2.3 ghz Quad processor. Main reason, you have more processors and it will be able to handle more users. Each connection could run on separate thread (core).
The bottleneck won't be the CPU for each of those connections.
