Upgraded a 3 year old Dual Quadcore 12 bay SuperMicro box over this past weekend. Added 64GB RAM, added a LSI SAS 9211-8i HBA next to an existing SuperMicro SATA Card. The bottom shelf of the chassis is SATA (4) wide. Bay 1 & 2 are controlled by the on-board SATA controller while 3 & 4 are PCI SuperMicro Controller. The LSI HBA handles it's half (4) bays - each side.

PURPOSE: Fast ISCSI SAN for my Xen Environment

I placed (4) Intel S3700 SSD's in 2.5 HS Trays on the bottom shelf. Bay 1 & 3 are considered (System OS ie rpool - recently added mirror by below output). Bay 2 is "datapool1" ZIL. My budget at the time only allowed (4) 600GB WD SAS Drives.

Here is my ZFS Layout. Any advice or criticism?
