I need to choose the specs for a server to support DOORS. Currently, we have a Dell PowerEdge 750, 2.4 GHz, 512 Mb of RAM, and a 40 GB Sata Hard drive. Do you guys think that this server is powerful enough to support 9 clients right now and possible more clients in the future or should I scrap this server and buy a more capable machine.

Hi, Derrick.

I think, this configuration is powerful enough (yet).
For our DOORS 5.2 database we use a dual Intel P2-200 MHz (!), 512MB, RAID5-80GB for about 15 users (there are ~5 power users).
By the way, this computer was used as a file server, a (extranet) web server, a mail server .. ok, that does it.

For the DOORS 7.1 database we use a (simple) AMD Athlon 1,6 GHz, 512MB, RAID1-40GB system.
There are also about 15 users online.

But now... we get an HP ProLiant (2x 3,6Ghz Xeon, 4GB, RAID5-270GB) - great!
We are planning to connect about 30-50 users online to this database server (with DOORS 5.2 / 7.1 and (of course) DOORS 8).

Anyway, in all cases the local area network could be the bottleneck. The main work is done on client side (of DOORS).

Dirk.

Hi guys,  I think you need to look at what you are doing with the tool more closely when choosing the servers.  I have a Citrix farm of 12 HP DL380G4's running which are highly specified in terms of memory and CPU, and they support 20 - 25 people per machine concurrently.  Sounds heavy but we get only reasonable response as the users insist on embedding lareg OLE's and carrying lots of history, which loads the machines up.  So please consider how your users will be working.

As Dirk said the bottleneck will be the volumn of data traffic on the network, not the speed in which that data is processed. Get a faster server, good. Get a faster network, great.

The main advantage to deploying Citrix (usually as a farm of several servers) is that the Citrix farm is 'close' meaning 'fast' to the DOORS server. Screen shot updates from Citrix to the client machines (acting as dumb terminals) is a LOT less than the normal data trafic between DOORS server and client. Years ago I did some crude tests on DOORS v4 and concluded that for normal modules the screen shots were 1/6th as much traffic as the data; a whole lot less when modules were highly linked to other modules. The other main benefit is you can more easily control the installation of a few Citrix DOORS clients rather than a potentially unlimited number of DOORS clients on the variouls folks desktop computers.

In fact I'm now arguing for mandatory Citrix access to DOORS and disallowing normal Client access.
