Re: [WIRELESS-LAN] WCS- virtualized?
Lee, I should have added that with are WCS on ESX that I rarely see the CPU Util above 1%, Disk i/o is low, as is the memory footprint. Looks like the only load comes when running reports. My Cisco SE commented that it was the best performing WCS he had come across. Of course, the ESX box is dual quad-core 3GHz with 8GB RAM, but again, the load from WCS is almost non-existent.

Re: [WIRELESS-LAN] WCS- virtualized?
Although we have but 400 LWAPP's and 4 4400 controllers; we've had our production WCS in an ESX Virtual Environment for over a year. No problems have surfaced, and I'd call that successful. The virtual world is the way to go - maybe. Phil On Dec 19, 2008, at 6:52 AM, Lee H Badman wrote: I am experimenting with WCS in an ESX virtual environment.
