Physical Disk Roaming And Data Migration - HP P3410A - NetRAID 1M RAID Controller Installation And Configuration Manual

Chapter 1
Enhanced Array Spanning
The HP NetRAID-1M and 2M adapters allow up to eight arrays to be spanned
together as one logical drive, although all the disks in the logical drive must be
connected to the same adapter. The maximum number of disks connected to one
adapter depends on the number of channels (one or two) and whether you are
using the internal or external SCSI connectors.

* External storage with HP Rack Storage/12 supports a maximum of 12 Ultra3 SCSI disk
drives.
Support for Clustering
The HP NetRAID-2M adapter can be used as a shared storage controller in
HP Netserver cluster configurations. HP Netserver clusters provide reliable,
increased-availability solutions for applications where unplanned downtime is
unacceptable.
Either the HP NetRAID-1M or the HP NetRAID-2M adapter can be used as a
local storage controller.

Physical Disk Roaming and Data Migration

HP NetRAID-1M and 2M adapters allow physical disk roaming, in which the
adapter keeps track of disk modules if they are moved to different slots in the
hot-swap cages, as long as the slots are all controlled by the same adapter.
With the exception of the NetRAID-4M, all disk modules on older adapters can
be moved to HP NetRAID-1M and 2M adapters, without losing data readability.
