Slow Snap Server 4200
 
I have a client who is running a Snap Server 4200 with 1 TB of disk space. He has 30 or 40 users accessing it and many users are reporting slow access. It could be a network issue, but I've already checked out a couple of other things and I think that it's the Snap Server.

I'm having trouble getting in and troubleshooting it -- I can log into the admin console, but it's difficult to tell how heavy disk access is. Does anybody have any suggestions?

Thanks,

Josh

You may have lost a drive and runing in degeraded mode. First, once you connect to the admin, bring up the log. Logs are located under the monitor section. I assume that the front panel is not showing a failed drive. Under the storage section you can check on drive status, usage.

I've already looked through the log files - no significant error messages. I'm pretty sure that it's not a degraded drive in the RAID disk set.

What I would really like to do is get some disk statistics to determine how heavily the drives are being used. Perhaps some of the file-sharing burden needs to be moved to another system, but first I need to determine if over-utilization is the problem.

Also, I've noticed that some swap space is being used on the system (I am monitoring via SNMP). The client has 1 GB of RAM on the system -- can more be added and would there be a benefit in doing so?

Thanks,

Josh

You can add some ram to the 4200. I bumped my 4500 up to 1 gig. What I noticed is that it buffers then data more during writes.

Mine I this installed and just matched it so their would be no conflict.
512 Infineon DDR 266 PC2100 CL2 ECC REG

Is most of the access read or writes (slower)?
