recently installed ESXi (free) for home use testing/study. ESXi boots from USB stick.
i have 2 SSD's for storage, one 1TB for VMs and one 64GB for host cache.
how much cache does the host require? i ask because i'd like to use part of the host cache disk to put a dir on it to store ISOs of OS's i want to install on the 1TB drive and test.
