I have a few oldish servers running virtual machines but they are limited to 16GB RAM and that limits the number of VMs I can run and the options for RDS.
I've added a RAID1 array of two Intel 311s: 20GB SLC SSDs, and configured them as swap on the host, in the hope that I can now more confidently over-allocate the available memory to the VMs.
So far so good in testing, but before I go any further I want to ask whether I'm missing any big reason why this is going to be a bad idea?
I should perhaps have mentioned that several of the VMs are used very intermittently but I can't reduce the memory they have as when they are active, it is needed.
