SC933 NAS Build
Well I had a SuperMicro SC933T server hanging around doing nothing so I thought I would use the case for a NAS build.
15 SAS/SATA hot swappable drive bays are located along the front of the case.
4 large cooling fans are located just behind the drive bays and there are also 2 fans on the back of the case.
The mother board in the unit has 2 single core AMD cpu’s and 8gb of ram.
The problem was the existing mother board only had PCIX slots and I needed PCIE slots (the unit was slow as well).
The server was equiped with an LSI MegaRaid controller (8 port) that only supported up to 2Tb SATA-II drives.
Way to small for a NAS…
So I removed the existing mother board and went looking for a new Mother board and CPU.
I ended up going with an Asus A88X-Pro.
It had enough PCIE slots to do the job.
32Gb of G.SKILL Ripjaws X Series 8GB 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) RAM was also installed.
The new mother board could only control 3 fan (plus the CPU fan) and with out the mother board controling the fan speed the unit was way to lound.
I plugged the mother boards fan connectors to the two back fans and one of the big fans behind the hard drive bays.
To slow down the other 3 fans I used some Zalman ZM-MC1 Multi-connector fan adapters that ran the remaining 3 fans behind the drive bays at 5 vdc.
This quieted the case down a lot (and later proved to provide ample cooling).
For a new raid card I went with a LSI MegaRAID SAS 9260CV-8i.
This is a great controller and supports SAS as well as SATA-III drives as well as using SSD’s to cache for the regular hard drives.
It also has the addon CacheCade board installed.
I used the 6 SATA-III ports on the mother board to connect to the next 6 open drive bays.
This left 1 unconnected drive bay.
I also installed a StarTech PEXESAT322I PCI-Express SATA III (6.0Gb/s) 2 Int/2 Ext SATA Controller Card.
This is connected to a StarTech eSATA 8-Bay Hot-Swap 2.5/3.5-Inch SATA III Hard Drive Enclosure.
The mother board has a 1Gb ethernet port built in but was not going to do, so I installed a Chelsio S320E 10GB 2 Port PCI-E Fibre Channel Card in the unit.
This allows for a fast fibre 10Gb connection to my Switch.
Here are some shots of the completed NAS unit.
The new mother board dropped right into place.
I set up 2-1Tb SATA drives in a Raid-1 for the OS and 4-6Tb SATA drives in a Raid-60 for the main storage.
I have to 250gb SSD’s acting as a Cache for the Raid-6 array (CacheCade). It really speeds up the array.
A few spare SATA drives in a Logical Volume are used as a local back up.
I also back every thing to the external hard drive enclosure.
My data should be safe as houses.
Ok what to install for an OS?
Of course I thought about running FreeNAS but as I have had great luck with Ubuntu Linux so I went with the 64bit Ubuntu Server distribution.
No ZFS but oh well I can always upgrade.
