I'll do the same as I did with the other two storage chassis, install fan controllers and line the entire thing with SilverStone Sound Dampening Acoustic Foam. That does wonders, especially for the Netgear 10G switch, it was crazy loud before installing the Acoustic Foam.
Just curios, which drives did you buy?Wanted to give an update, I destroyed my Raidz2 for the VMware Storage, added six more 300GB SAS drives (for total of 24 drives) and made 12 vdev with each vdev being mirrored.
I also installed second LSI card, took my two Intel x25-e 64GB SSD drives, added them to the new pool in a mirror and put the log/zil onto it. Since I’m using iscsi I went ahead and used the command zfs set sync=always on the pool. The reason I did this was because my storage controller 10G nic failed after two years, which caused a couple domain controllers to corrupt, wasn’t a big deal, restored from backups and everything was fine again (I do backups twice a day.) I have purchase a second 10G switch and now have two 10G nic’s installed in the storage controller, this way I can go back to sync=disabled if I want.
I’m also excited to say I have bought another storage array, the Supermicro SuperChassis CSE-847E16-R1K28LPB which has 36 HDD bays. I did this because last week I officially filled the entire first Supermicro storage chassis 24 bay all with 300GB SAS drives and the second Supermicro storage chassis 24 bay all with 3TB drives. Need more room to expand. :D
(And if possibly from where)
I have a vendor that hooks me up with the drives, I buy the "Seagate Cheetah 15K.7 ST3300657SS 300GB 15000 RPM" before that I would just buy used ones off ebay, which I have had very good luck with
$32.88 each from this guy:

Well, luck is something we try to avoid here in the forum, don't we? [emoji12]
The best test for backups is their dust-resistance
Another Update, When I installed the two Intel x25-e 64GB SSD in a mirror for the slog, so I could enable sync writes for my vm's over iscsi, the performance was pretty good. Just for fun, I disabled sync write, deleted the mirror, removed the two Intel drives and added added two 120GB Mushkin Enhanced ECO2 just to see what the performance was like and of course it was TERRIBLE lol, the latency went through the roof. I only did this because I wanted to see how bad it could get. Today my two 200GB Intel S3700 SSD drives arrived to replace the old X25-e and wow performance is so much better then the X25-e for SLOG, I am very happy with the upgrade and almost feels like sync writes have been disabled.
