RE: Virtualization of airwave
Ryan, We were actually encouraged to run our new Airwave implementation as a VM, so I don't think Aruba has reservations about it being in a virtual environment. That being said, we run 250 devices, we have allocated 2 virtual sockets, with 2 cores per socket, 16Gb of RAM (Aruba recommended). Memory usage stats show usage is 10-20%. The CPU stats for this VM run gernerall around 7.5% with peaks to 15-20%. Disk throughput is about 500-1000KBps with one peak to 2500 KBps. WE have had this running since May. It performs really well. This VM runs on a cluster with Intel E5-2690 @2.90GHz processors. The hosts are dual socket only with these 8 core processors. The back end storage is a Compellent array (with iSCSI connections to the VM hosts) that will auto-tier depending on the demand. So a high end Netapp will be more than enough to support the Airwave demands.

Re: Virtualization of airwave
I've been running amp in a vm for several years... ~900 APs, 7 controllers (cisco environment). No issues what so ever. 4 cpus, 8192 MB ram. Processors in the esx hosts are X5690s, 3.47 Ghz.

RE: Virtualization of airwave
We have an airwave installation that is on the smaller side, only 120 AP's and 1 controller. It runs great in VMware, though. 2 virtual CPU's (Xeon E5620) and 8GB RAM as well. For us, it seems to hold steady at 20% CPU utilization/1Ghz in use and around 1.6GB memory used, with the usual spikes when things get busy. No complaints about it whatsoever. -Patrick Patrick Mauretti Sr. Network Admin Massasoit Community College 1 Massasoit Blvd Brockton, MA 02302 508-588-9100 x1660 On the internet, nobody knows you're a dog.
