Thanks, Ed! This is exactly the kind of feedback the Dept. needs to know.
You said, "...four to six users per system with this hardware." Don't forget, "this hardware," has 2 x dual-core 64-bit processors, so effectively it's like having 4 single processors. You still think this is under-powered for a university lab where the work shouldn't get near as detailed as in a manufacturing environment? I'm just asking you to rethink the scenario, since I realize you're probably used to a real world scenario.
Is there any Sun server you would recommend for the job? I hear what you are suggesting--multiple servers with a few users each, or everyone running on a dedicated workstation. Those are great suggestions, if it weren't for the budget constraints that a small school has to survive and compete within.
We do want to hear what you have to say--we just have to find a workable medium, and we value your experience in helping guide us in the best possible solution within our limitations.
Thank you!
Best regards,
John Ellard

==============
Although it says 2x73GB drives, I was told that a single (approx.) 250GB drive was discussed with the Sun rep. The purchaser of the system asked about purchasing an external HDD for backups--he does not want to rely on the network's nightly backups alone. I suggested a 2nd 250GB drive with both drives deployed using RAID 1 mirroring to address the purchaser's backup concerns.
This server is being considered for purchase in an environment with 33 Cadence products installed and a max of 20 remote Xwindow clients at any time (and each client could be running more than 1 tool at a time).
My main concern is 8GB RAM, since reading in the IC5141 documentation the strong recommendation of a 2GB swap space, just for that 1 product. Do you think a strong recommendation for 16GB RAM is justified with these requirements?
I would appreciate any comments, thanks!
Even with the maximum RAM of 16GB, it is going to perform poorly with 20
users. Advise them they need to watch the swap rate and may need to buy
another system, or three. I'd not want more than four to six users per
system with this hardware.
A better configuration might be twenty single processor workstations and
a file server. Connect them together on a fast subnet to minimize
traffic.
