Multiple

Channels

Per

Host

Adapter

(Multitasking)

When a host adapter has more than one disk drive connected, a performance increase can

be realized by assigning each drive to its own channel. This allows for multitasking on

the SCSI bus (because NetWare 286 can only do one I/O

per

channel at a time).

The NetWare 286 drivers

ASW-I440 v3.0 allow you to configure multiple channels

per

host adapter, thus allowing multitasking

the SCSI bus. This is done

allowing

the user to map a channel to a drive rather than a channel to a host adapter. NetWare 286

can do only one I/O per channel at a time.

The following hardware considerations should

be taken into account when preparing the

AHA-1540/1542/1640/1740/1744 disk drives for multitasking.

- The drives must

be connected on the same SCSI cable on the same AHA-

1540/1542/1640/1740/1744.

- The SCSI ID

the drives must be different

on the same SCSI bus (Note:

booting

desired

from

one

the SCSI drives, its SCSI ID must be

jumpered

0 and the port address

the host adapter should be set to 330H)
