I am trying to spec out a server machine to run VMWare ESX/ESXi to host about 3-4 VM's. They will likely be hosting VM's running IIS, Apache and BIND. We don't have a huge budget for this and to a certain degree this is an experiment in virtualization. If it works, we will apply this solution to the rest of our data center.
I am concerned about performance when using RAID technology across VM's on the same box. Does anyone have any advice/experiences they can share either in favor of RAID or opposed to it with multiple VM's (Hopefully we can avoid a general anti/pro-RAID argument). If your experience results in recommending against RAID in this case, how do you handle redundancy/availability? Thanks!
