Dual NetRAID 4M controller on a single server

[ML Chin]

hi All,

I would like to configure dual Netraid 4M on a single LH6000 server and have the two controllers mirror the array(s) which I will create on two RS12 boxes.

Is this configuration do-able and how do you approach this?

Thanks.

In general, there is no problem having multiple hardware RAID controllers in a single server so that part should work fine for you.

If I understand your question you want each controller to have it's own array of disks, but the two arrays will be mirrored?

You can do that with software mirroring but I don't believe there is a way to do the mirroring in hardware. Windows NT ftdisk.sys will give you the software mirror but the performance hit will be substantial.

HTH,
Paul
