A couple of constant VMs running, but I spin up test VMs fairly frequently to test things out and play with new setups. I'm not looking for killer performance, after all it's an AMD Penom II X4 server! The CPU is actually quite enough for my needs, it's the disk that's starting to get old and crufty. So instead of just getting a bunch of 2Tb disks, maybe it's time to get fewer large disks in RAID1 paired with 500Gb SSDs (for boot/OS and lvmcache) to get the system booting. I'm more concerned with durability and resiliency, than I am with absolute disk space and performance. Which is why I'm looking at fewer spindles. Does this clarify things?
