Hi all,
In this post before I was on this list: https://listman.redhat.com/pipermail/ataraid-list/2002-September/001190.html Samuel Flory said: ... On the downside it's not as full featured as more the mature raid controllers (no splitting arrays into logical device) ... and I'm wondering what he meant by that.
We have 2 drives which we want to use as a RAID1 mirror array. If we get the 3ware Escalade 7000-2, will we be stuck with using a single partition for everything? That sounds terribly inconvenient.
Logical device != partition What I mean is you can't divide an array into multiple logical drive/devices. Thus if you wanted to have 2 different logical drives. You be forced to create 4 different arrays, and lose an additional drive to parity.
A 3ware array is mapped to a single scsi device (example /dev/sda). The scsi device can be divided up into partitions normally with fdisk, or your install.
