The NetWare 286 drivers in ASW-1440 v3.0 supports the installation

multiple SCSI

hard disk drives in the file server. This might be desired for four reasons:

- to support disk mirroring (fault tolerance)

- to support disk duplexing (fault tolerance)

- to take advantage

the multitasking capability

(perfoonance )

add total storage capacity to the system

NOTE:

Disk

and

disk duplexing are only supported on

Mirroring

Disk mirroring is when two hard disks are installed on a single host adapter. These disk

The following hardware considerations should be taken into account when preparing the

AHA-1540/1542/164011740/1744

disk drives for mirroring.

- The two disk drives must be near the same capacity. NetWare will not allow

drives that vary greatly in capacity to be mirrored. Consult the NetWare

installation manual for the limitations.
