SCSI RAID 0 Question with On Board Controller

post #1 of 3
Thread Starter 
So today I found two 15k U160 36 GB SCSI Cheetah drives that I can get for free. I already have an Adaptec 29160 PCI SCSI card, so I got to wondering about RAIDing these two in 0. I know the PCI bus bandwith is going to bottleneck me to a large extent, but I feel the blazing access times will compensate quite a bit. My 970A-UD3 has on board RAID compatibility for 0, 1, 5, and 10, so will the on board controller suffice, or would I have to buy a SCSI card with RAID controller? If I would have to buy anything, the project is a no go; the only reason I'm even considering is because it is no cost to me.

You would need a hardwareRAID controller, but fortunately for you, SCSI RAID HBA's that use PCI are extremely cheap on eBay most of the time as so few people have any use for them.

That said, I was in a similar situation in which I received a box full of 36, 72, and 146GB 15KRPM SCSI drives (8x36 + 13x72 + 27x146) and 2 Adaptec, 3 LSI, and one each Areca and 3ware RAID controllers. Some were PCI but most were PCI-X.

I experimented with them in a home server setup using a dual-LGA771 board with a ppair of 4core XEONs, 24GB DDR2-800 3-3-3-6, and a mix of PCIe, PCI, and PCI-X slots.
I was able to saturate the PCI bus easily, and the PCI-X bus would be filled before all the 24 146GB drives were added to the RAID0 array, but it was not any faster than 4x 2TB WD RE4 drives in RAID10 yet used something like 4.8x as much power while delivering the same amount of space with an immensely higher chance of failure.
Basically, you will be limited by GbEth speeds if using them remotely (about 200MB/sec),and I would not want to have them inside my case!

I was afraid of that. Looking at my detailed board specs the other day, it definitely seemed to indicate that the RAID controller is SATA bound. I then thought about doing what you did, making a home server box, but came to the same conclusion you found: energy and expense outweighs modern alternatives. While the PCI cards on ebay are cheap, I'm not sure it's even worth the trouble; for a fair amount more, I can just get a SATA III HDD to RAID with, or additional SSD.
