Just as an update. I installed the second Adaptec 31605 today, filling all 16 ports with 8x WD Greens, 6x Hitachi 2TB, and 2x Hitachi 1TB drives. There is an additional 1.5TB Seagate 7200.11 being used as an OS drive. That’s 27.5TiB raw capacity.
Here’s a view of all the drives currently in The Big WHS. Note, I may have killed yet another WD Green. A single SMART error so I’m making quadruple sure that something isn’t wrong.
Tomorrow I will start creating the arrays and just start copying as much as I can to see if I can break things. The WHS Virtual Machine seems to be very stable in Hyper-V.
Along other fronts, the old WHS is down to a single Adaptec 31605 with 10x 1.5TB and 2x 1.0TB Seagate 7200.11’s. Available space is getting pretty low on there:
That 400GB is enough for 3 weeks… so if the new WHS doesn’t prove stable, then I’ll have to add drives to the old WHS.
Finally, on the hardware front, a few developments:
- I spontaneously purchased another Antec TruePower Quattro 1,000w power supply as it was on sale for $129.99, and works great in the old WHS.
- I ordered a Intel Pro/1000 PT Quad port NIC. With the virtualization, and my distrust of the Realtek GigE ports on the Asus P6T7 WS Supercomputer, I decided this had to happen at some point.
- I ordered a HP SAS Expander. HP Part Number: 468406-B21 This device allows one to connect 24 internal and 4 external ports to a single 4 port SFF-8087 connector. If it works, I will probably purchase a second and run all of the arrays off of the Adaptec 5805 instead of dual Adaptec 31605’s. Total port expansion would be from 40 ports over three cards (16, 16, and 8 ) to 56 from one card (8->28, 8->28). If it doesn’t work, it is a $200 experiment. The major advantage to keeping everything on one card is that hotspares can be shared between the two 8x 1.5TB Raid 6 arrays. At the current WD Green failure rate I almost want to keep two 1.5TB hotspares.
- The Perc 5i’s did not work well on the Asus board (I did not pinmod them this time). At times they threw d4 errors upon boot and other times they would allow the machine to boot but would not work in Windows Server 2008 R2. Just to verify that the cards worked I installed them on an old Q6600/ nVidia 680i motherboard system and everything worked perfectly well.
- I bought a second Hitachi 1TB retail drive. I have been very happy with them thus far and decided to add another drive. Odds are I will either use two raid 1 arrays or a raid 6 array with the four 1TB drives. I have also been contemplating using some of the 1.5TB drives.
That’s all for now!
