I have a whitebox home lab computer. I've been slowly learning about VM's and ESXi. I'm now trying to learn the disk system aspects.
From what I've gathered, you can run about 3 or 4 VM's in an ESXi box before you start suffering from disk i/o bottlenecks. I understand that you can alleviate this by buying a card with "write-through" capabilities. But then there are things like battery backups to think about, etc.
Given my home lab budget, i may have to buy something on fleabay. Can someone recommend a *specific* card model, along with any specific features to look for (battery backup), etc.?
Thanks in advance.
