Virtualization – use SLC exchange on the VM host as RAM replacement is wise?

I have some old servers running virtual machines, but they are limited to 16GB RAM, which limits the number of VMs I can run and the options for RDS.

< p>I added two Intel 311s RAID1 arrays: 20GB SLC SSDs and configured them as swaps on the host. I hope that I can now over-allocate the available memory to VMs more confidently.

to So far, it has done a good job in testing, but before I research further, I would like to ask, have I missed any major reasons why this would be a bad idea?

I might have mentioned that several virtual machines are used very intermittently, but I cannot reduce the memory when they are active, which is needed.

No, it is not a good substitute for real RAM. SSD drives are an order of magnitude slower than RAM…but you know :).

Under limited memory conditions, the drive’s write endurance also has problems.

If the solution seems to work well in the test, then try to use it… but know that it is correct The method is to equip the system with the necessary amount of RAM. If your system cannot accommodate this much RAM, then it is time to upgrade to modern hardware.
