Re: Please see System Specs inside and comment. Thank You! :)

Thanks for the quick response!

Let me see if I understand you correctly. Are you saying they need to purchase 20 licenses and run a licensed copy on each workstation and just use the server to store the data files (drawings and such) from Cadence?

The environment is the Electrical Engineering Lab on a small university campus. The professor purchased Cadence to install on a Sun server and have from 1 to 20 students access it at a time from Windows workstations in the lab. Are you saying that's an unrealistic expectation or goal?! If it is, it's critical I tell him now BEFORE he purchases that Sun Server 4200.

Thanks, Edward!

==============

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.
