Yah, RAID10.

- Two nodes with 4 WD 3TB RED

- One node with 2 WD 3TB reds and 6 * 600MB SAS Velocirtprs

High Endurance High Speed SSD's for SLOG devices on each node. Std SSD's 
don't cut it, I've run through a lot of them. ZFS/Gluster/VM Hosting 
generates an extraordinary amount of writes. And the quoted write speeds 
for most SSD's are for *compressible* data, their performance goes to 
shit when you write pre-compressed data to them, which I have activated 
for ZFS.
