Attach Sequence Worksheet - HP xw4000 Service & Reference Manual

Ultra ATA Drive Guidelines and Features
The attach sequence rule may also be stated in table format:
General Attach Sequence Rule*
Sequence

*If there are three or more devices, two or more of which are hard drives, two hard drives should
be attached to the primary controller first before following the General Attach Sequence Rule.
The rules allow for:
Keeping the hard drive on a separate controller channel maximizes drive performance until a
fourth device is added.
Keeping the hard drives and removable media drives on separate controller channels
maximizes compatibility.
Keeping the hard drive and the writable optical drive on separate controller channels
maximizes optical drive reliability.

Three device installation
Four device installation
4–4
The lowest class drive - bootable hard drive recommended.
If only two drives, the last drive goes here; otherwise the lowest class of the
remaining drives.
If only three drives, attach the final drive here. If a fourth drive exists, attach
the lowest class drive here.
If there is a fourth drive, attach the final drive here - the drive with the
highest class number of all devices.
