Lots of compute and disk, at 125 watts idle!
- Supermicro 7046A-3 (this is a very quiet chassis! Purchased at Newegg for $924)
- Intel Xeon E5620 Westmere-EP 2.40GHz (Purchased at Newegg for $389)
- 12GB DDR3 ECC RAM (3 @4GB), Unbuffered (Kingston, $199 from Newegg)
- 6 @ 1TB 7200rpm SATA drives (5 Samsung Spinpoint F3, 1 Hitachi, $59 each from Microcenter on sale, purchased prior to this build)
- 2 @ 320GB Seagate 7200rpm SATA drives (purchased a few years ago, sitting in a pile in my garage)
- 1 USB key (boot)
- DroboElite for bulk iSCSI storage
Operating System: VMware ESXi 5.0
- FreeBSD 8.2 (primary NAS device, see below)
- Windows 2008 R2 (used for VSphere Client, misc)
- Linux (VMware VMCA) (off for now)
- Linux LAMP server (running this site)
When I added the physical drives in the order that I wanted them (i.e. 4 data pool drives imported from a FreeBSD system all physically contiguous), the LSI controller didn’t map them in the same order. So I get a different numbering than the left-to-right ordering of the drives in the drive bay.
6 drives PCI passthrough via the embedded LSI SAS controller, and an additional 2 320GB used over SATA bus by ESXi for datastores ds1 and ds2.
The system uses 160W (measured at the outlet) when all 8 drives are spinning (but idle). I currently use a spindown daemon to spin down the 6 passthrough drives when they aren’t busy. This means the 4 in the data pool (which is our home NAS primarily) are spun down most of the time. The 2 in the Time Machine backup pool spin down at night, but are up much of the evening due to 5 Macs in our house using it for backups. It uses 122-127W when all but 2 drives have spun down.
