I have a PowerEdge 2970 server with a: SAS6i/R Integrated Controller for PowerEdge 2950/2970, x6 Backplane http://accessories.dell.com/sna/products/cables/productdetail.aspx?c=ca&l=en&s=corp&sku=330-2277

I just bought 3 hard drives that I plan to use in a RAID Configuration I believe it's called a Raid 5 Configuration where there's 1 main drive all the stay in Sync.

My question is: Will the SAS6i/R Integrated Controller work?

Or do I need to buy something like: Dell Perc5I PCI-E SAS RAID Kit for PowerEdge 2970 http://www.xbyte.com/ProductDesc.aspx?code=CAT_832_25

Thanks!

Looks like the SAS6i/R only supports 2 drives and RAID 0 and 1 so you will need to purchase something else to do RAID 5 with 3 disks.

  • Hello, so you are saying I can do a Raid with just 2 drives? Meaning instant mirroring on the 2 drives? I think 3 was over kill anyway. – aron Jun 10 '11 at 19:08
  • You do can RAID 1 mirroring with a number of drives divisible by two. So yes two drives in RAID 1 will work with your current controller. – xeon Jun 10 '11 at 19:10
  • cool thanks, you just saved me $350 :) – aron Jun 10 '11 at 19:12

The SAS6i/R only supports RAID 0 and 1 for up to 10 devices on two channels. So you will not be able to create a RAID 5 array with the three drives you have. You will need the Perc5/6 to do RAID 5. Call Dell to ensure you get the correct controller and cables to connect to your back plane.
