At work I have three IBM HS22V blade servers that have 2 SSD (60GB) in raid-1. At the moment ESXi 5.0u2 is installed onto the SSD, but I'm going to reinstall ESXi onto USB keys to completly free the SSD.
I want to enable Host Cache on local SSD. Should I keep it as raid-1 (maybe have to tag the raid-disk as SSD), or should I run it as seperate SSDs and use one as Host Cache and find another use for the other?
This is a production environment so right on top of my head I would go for raid-1 for redundancy, but I'm not sure what would happen if the SSD which hosts the Host Cache would die.. Would the ESXi host crash (what I think), or not?
