HP 3PAR Windows 2012 and Windows Server 2008 Implementation Guide

• The maximum number of usable LUNs per host port is 255. Although the HP 3PAR StoreServ
Storage can export LUNs 0 to 65535, only LUNs 0 to 254 should be used for Windows
configurations.
• For an HP 3PAR OS earlier than version 2.3.1, the maximum LUN size that can be presented
to a Windows Server is 2 TB; for version 2.3.1 or later, the maximum LUN size that can be
presented to a Windows Server is 16 TB.
Discovering LUNs
Use the Server Manager utility to display information about the disks: click Storage, and click Disk
Management. “Listing Disk Devices” (page 65) shows an example.

You can also use the Emulex One Command Manager or QLogic QConvergeConsole to discover
devices.

Disk devices on Windows servers can be used as basic disks or dynamic disks. The HP 3PAR
StoreServ Storage already provides most of the extra capabilities of dynamic disks. HP strongly
recommends that HP 3PAR StoreServ Storage volumes be used only as basic disks unless any of
the additional features of dynamic disks are a requirement.
