I have turned my attention to using a slog for my array. It's not that I really need one, things seem to be running reasonably well so far, but I am interested to see just how much of a difference I can make by adding it.
Here's what my setup currently looks like:
I am using a Debian 8 VM with ZoL and have created a RaidZ2 array consisting of 8 x 3TB HGST Ultrastars. I have created 3 ZVols on the array, one for my Plex server's media (7TB), and a couple for my Windows domain (4TB & 1.5TB). All 3 ZVols are being accessed via iscsi, because it's easy, from the other VM's. I am not currently using nfs for an ESXi VM datastore, or was planning to, but I may in the future with another array. The array total is 21.8 TB or thereabouts. The VM datastore resides on a 250GB Samsung 850Evo and ESXi boots from a USB pen drive. I have not set sync=always yet, but rather left it as standard/ inherited until I have a way to move the zil away from the array.
I only have space in the chassis for mSATA devices, unless I go metal bashing, and would love to find something with power loss protection. So far I have looked for Intel 320/ 730 in mSATA but coming up empty. Is there anything else available for reasonable money?
