Continue to use SLOG if all the drives are SSD?

[Pointeo13]

I'm replacing all 24 disks that are 600GB 15K Seagate drives for 24 ScanDisk 960GB SSD that are used for my VMware storage. I assume I would want to keep my current SLOG for the low latency and Supercapacitor?

It depends. Is your SLOG lower latency than your all SSD pool?

 

[Pointeo13]

SLOG is 200GB Intel® SSD DC S3700 (Mirrored 2x)
Latency - Read 50 µs
Latency - Write 65 µs

Vs.

(24x) SanDisk SADSSDHII960
960GB Ultra II Internal Solid State Drive
I don't see the Latency info

I suppose I'll have to do testing with and without, so if it's lower latency with the SanDisk then it's ok to go without SLOG?

It's always OK to not use a SLOG. It just might be slow during sync writes (waiting for the pool to write).

Wanted to make sure, I want to prevent any type of corruption for my vm's since it's all done with sync writes through iscsi, I do backup everything to four other devices, separate storage array, QNAP NAS, crashplan and to tape, so I'm pretty safe, but always willing to do anything i can to prevent it all together.
