Trying to get a better understanding of primocache. Uncertain how it interacts with VMware guests. I’m using a 1TB ssd to L2 cache my hdds, among them a 10TB hdd that holds my virtual machines.

All my VMs use a fixed hdd size of 100gb.

If I load one does it essentially write 100gb to my ssd and as such if I load 5 of them half my L2 is used up?

No, PrimoCache only caches disk sector data that were read. VM may only reads a small portion of data within a 100GB vm file, then only that portion of data will be cached.

When cache space is full, PrimoCache will replace the old data by new cached data according to cache replacement algorithm.
