32 Configuring Shared Storage on Your Dell|EqualLogic PS Series Storage Array

Aligning the Disk Sectors

For optimal performance with PS Series volumes, it is recommended that you

configure the volume disk partitions to begin on sector boundaries that are

divisible by 64K (that is, evenly divisible by 65536 bytes or 128 sectors).

This makes the sectors match the default PS Series storage array RAID stripe

segment size and improve volume and overall group performance.

NOTICE: Use the diskpart utility in the Windows 2000 Server Resource kit to align

the disk sectors. Do not use the Windows Unified Data Storage Server 2003 utility

diskpart to align disk sectors on a PS Series volume, because you do not achieve

the desired results.

For more information, see the technical report Microsoft Windows: Aligning

Disk Sectors for Optimal Performance on the EqualLogic Customer Support

website at www.equallogic.com.

Configuring a Basic Disk

When you perform the disk sector alignment procedure, as described in

"Aligning the Disk Sectors" on page 32, the default action creates a basic disk.

NOTE: Do not convert the disk to a dynamic disk. Dynamic disks are not supported

with iSCSI volumes.

Assigning a Drive Letter and Formatting a

Partition

After you have aligning disk sectors and created a basic disk, the new volume

is seen in the Disk Management utility as On-Line and Healthy. A disk

associated with a connected PS Series volume is referred to as an iSCSI disk.

NOTE: Although you can create multiple disk partitions on an iSCSI disk, it is

recommended that you only use one partition. For details on assigning a drive letter

and formatting an iSCSI disk, see the technical report Deploying Microsoft

Windows Server 2003 in an iSCSI SAN on the EqualLogic Customer Support website

at www.equallogic.com.
