After more than 5 years, I am retiring the server and putting in a new one. The new one is based on the ITX form factor so it is much smaller and cooler. Specifications as follows:
Fractal Design Node 304 Mini-ITX Case (Black)
Asus P8H77-I Intel Skt1155 Mini-ITX mainboard
2 x Kingston 8GB 1600 DDR3 Value Rams
Seasonic G-450 450W Modular 80+ Gold
6 x Western Digital 3TB Green
Sonnet Tempo SATA E2P
Installation of Ubuntu Server 12.04 LTS is uneventful and it is quite speedy. ZFS on linux is now a robust solution and boy is it a nice filesystem. Getting a raidz1 ZFS filesystem on the 6 3TB was a breeze and performance was good. Bonnie++ showed ~250 MB/s for reads and ~220 MB/s for writes which is more than good enough for me since my networking is limited to 1Gbps. To the main machine, a 4bay and a 8way Hotway enclosures were connected via eSATA. 6 x 1TB and 6 x 2TB drives were installed in them. Performance on the external enclosures were limited to about 100 MB/s due to the nature of the addon card (1x PCIe).
An 8 hour mprime went well and a copy of the previous data to the new drives was also alright so the system appears to be stable. The entire move took almost a week with testing and migration of the data taking up most of the time.
The old server to be retired is shown below. It will be missed.
