emuhack Posted March 11, 2020 Share Posted March 11, 2020 I have a Poweredge Blade Server and want to make it my VM and Docker Unraid Machine, currently windows server 2012 with hyper-V (my other machine is in my signature) - The machine in my signature is going to be PLEX and storage machine. I don't really need storage in the new machine. I read that a SSD array is not "recommended" or "supported" - has anybody had an experience with that or tested? I was thinking of keeping 2x of the 512gb 10k drives for data array with parity, and 2-3 SSD drives for a cache pool for VM storage and Docker Storage. I would do 4-5 SSD's if it was OK to do that, but like I have read its not supported. I just want to have SSD speed for the entire system, I will use CA/Backup for Data retention of the dockers. Just looking for anybody who has a similar system and what they did and or give me some insight. Thanks! Quote Link to comment
JorgeB Posted March 12, 2020 Share Posted March 12, 2020 It's fine to use SSDs in the array, at least for most of them, I remember an old Kingston model that would give a few sync errors after a power cycle, but it's the only one I know about, the main issue currently is that the SSDs in the array can't be trimmed, so they might lose some write performance/endurance, also I recommended using a faster SSD for parity, I've been using a small SSD array for some time and it's working well for now, don't notice any performance issues even without trim, I use regular SSDs for data devices and a NVMe device for parity.

testdasi Posted March 12, 2020 Share Posted March 12, 2020 I'm running a mixed SSD + HDD array and there's no issue to speak of. (I do know array SSD can't be trimmed but then I don't do aggressive write activities on array drives. I have dedicated unassigned devices for write heavy stuff). Quote Link to comment
