Expander backplanes can support multiple SAS or SATA drives with a single SAS HBA (controller) port. Intel has 4 and 6 drive expander backplanes that are compatible with the SC5650. See the Spare Parts and Configuration Guide for the SC5650 for more information.
Thank you! That is a very useful document.
We have checked this AXX6DRV3GEXP backplane. It seems this can contains 6 hot-swap drives but requieres only 2 ports on the controller. We would like to set-up an array without the backplane this time (just connect 4 drives to each ports and set up a RAID 10 array).
Later when we buy this backlane, do we have chance to set up two arrays with it in this way?
- Disconnect the 4 drives form the LSI card
- Connect the backplane into 2 separate ports of the controller
- Put the disconnected 4 drives into the backplane (with the existing RAID 10 array)
- Put extra 2 drives into the backplane
In this way can we use/recognize the existing RAID 10 array and set up another RAID 1 array with the extra 2 drives?
Thank you for the answers!
