Can I use mix SAS and SATA drives in the same enclosure if the only SATA drives are Cachecade SSDs?

Jump to solution

Hi,

A client has the following configuration:

  • RS2BL080 with the CacheCade feature key
  • S2600COE motherboard
  • P4308XXMHGC chassis (which includes an enclosure with 8 x 3.5" hot swap bays)

Six of the hot-swap bays are currently populated with RAIDed SAS HDDs. The customer would like to use two SSDs in CacheCade, but they have been unable to purchase SAS SSDs at a reasonable price.

Page 3 of the http://www.intel.com/support/motherboards/server/rs2bl080/sb/CS-030637.htm Intel� RAID Controller RS2BL080 — Hardware user's guide states:

Note:Intel recommends that you carefully assess any decision to mix SAS and SATA drives within the same virtual drive. Although you can mix drives within the same virtual drive, Intel strongly discourages the practice. However, you should never mix SAS and SATA drives within the same enclosure.

The customer would like to purchase two Intel DC S3700 series drives, install them in the vacant hot-swap bays, and use them for CacheCade. Will this work?

Thanks for the quick reply.

Any hope of Intel releasing a SAS SSD?

Skye,

I don't know. I'm primarily involved with Intel Server products. You might want to ask this question over in the /community/tech/solidstate Solid State Drives community.

Skye,

I've learned that Hitachi GST and Intel signed a joint development agreement in 2008 for enterprise-class SAS SSDs:

To minimize integration issues, be sure that any drive you choose is validated with your server system.

John
