• Monitor VMware ESX Server Performance for free - VM Monitor - Free tool to monitor VMware ESX. To use VM Monitor, you need to have SNMP enabled in ESX Server (sorry, ESXi server doesn’t yet support sending performance statistics via SNMP, thus, VM Monitor is not compatible with it at this time)
• Allowing root SSH access to ESX host

RAID Controllers

SRCSAS144E should work. More info:

If you do get an intel controller (besides the ones below) make sure that when you build your volume, to enable the Read Policy to 'Adaptive Read Ahead' and the Write Policy to Write Back. uncheck the box to force it 'write through' if the battery is missing (to force it write back). this will provice you insane performance by using the cache on the controller. Be sure to have a UPS or get a compatible battery backup unit.

SRCSASLS4I should work... link one | link two - looks like it will use the driver megaraid_sas version 3.0.21.11vmw
