Re: Attaching Linux box to [EMC] SAN

Thanks John, that was helpful. I am really looking for similar high

You mentioned that after LUNs are created, they function as regular
disk devices.
1. Does that mean I can configure RAID over it?

I suppose in theory you could do software RAID over SAN volumes. But SAN volumes are almost always hardware RAID, so I don't really see the point.

2. How would it work for controllers?

I don't understand this question. What "controllers" are you referring to?

3. Can I mount the filesystem with say, writeback mode (or with noatime
setting)? Would /etc/fstab file work the same way?

You'll have /dev/sd?? devices, just like you would for SCSI (or SATA or USB) disks. What you do with them is up to you. You have to put the filesystem on them (ext3, XFS, any filesystem you like) and then can use whatever mount options are appropriate for that filesystem. There is no difference (AFAICT) between a locally attached SCSI disk and a SAN volume.
