Wow! 6 scanners for 4.4 TB of data! isn't that an overkill. We have a 960c cluster with ~7 TB of CIFS data, but just 2 scanners and no issues so far. However we did see those kinds of drop off when we were running the older verison of VScan, i think it was 6.x. After upgrading to 7 we haven't seen any disconnections. One change we did though was on the auto updates. We set it to be done during the weekends at night when the system is almost idle (at least the CIFS side). We did see issues when the autoupdate ran during the weekdays. -G

The basics:

• F940c systems (one cluster)
• ONTAP 6.5.2
• ~4.4 TB of data (90% CIFS)
• McAfee VirusScan 7.1 for NetApps
• 6 x scanner systems (4 x PowerEdge 650SC, 2 x Precision 420)
• All scanners scan both filers
• All GbE, all systems & filers on same subnet

We've been having a small problem with our McAfee virus scanners lately; they all periodically drop off-line causing much havoc with our pagers. Suggestions from McAfee are that the scanners become too busy and when that happens, they drop off line and reset themselves. However, performance indicators on the scanners don't indicate any problems: CPUs almost idle, no disk I/O, very little network activity. From a filer stand-point, they're practically idle: CPU time averages less than 20%, network and disk I/O is minimal.

I'd like to hear how some of you have your McAfee environments configured and what (if any) issues you've had similar to this one. As usual, much thanks in advance!
