MSA30 x 2

Jitendra Samji — Fri, 20 May 2005 16:40:19 GMT

Hi,

My Kit:
DL560
2 x MSA30
2 x 6404

Can I connect the 2 x MSA30's to the controllers and then Raid 0 them first then RAID 1 them together.

See attached DOC..

There is no DOC attached, but you need an operating system-based RAID-1 to mirror between two SA6404 and even the SA6404-base / EM.

You can also connect two SCSI busses to a SA6404-base or EM and run a pure controller-based RAID 0/1 combination.

Hi Again..

can you explain how i can connect two SCSI busses to a SA6404-base or EM and run a pure controller-based RAID 0/1 combination.

The setup I am trying to do is:

1 channel to 1 x msa30 = raid 0
2nd channel to the 2nd msa30 = raid 0

then finally take both msa30's and create 1 raid 1.

Well, the controller will do it for you automatically.

You select an equal number of disk drives from both busses and create a disk drive array. Then you create a logical disk. It's been some time since a worked with the ACU, but I think they still call it RAID-1. However, the SmartArray controller recognizes if more than two disks are involved and he will put mirrors on disks in different enclosures and then stripe along the mirrors.

I have already explained this in my first response...
