HP Matrix Operating Environment 7.2 Logical Server Management User Guide

Logical server storage
Matrix OE allows you to logically represent your storage environment in a logical server storage
configuration. A logical server completely defines your storage, including all Fibre Channel ports,
fabrics, server WWNs, storage WWNs, volumes, and LUNs.
For server with Virtual Connect logical server storage, HP recommends Fibre Channel Storage
Area Network (SAN) with boot-from-SAN capability.
• Matrix OE supports any Fibre Channel storage solution, which supports the Virtual Connect
environment, N_Port ID Virtualization (NPIV), and boot-from-SAN capability (boot volume as
a pre-presented LUN).
• Matrix OE also supports Raw Device Mapping (RDM) for cross-technology logical server
operations.
To realize the benefits of Virtual Connect logical servers, including the ability to move logical
servers and to easily repurpose server blades associated with inactive logical servers, you must
remove or disable any local disks.
For virtual machine logical servers, Matrix OE supports VMware and Hyper-V virtual machines
whose boot and data storage are files within the hypervisor file system. That file system can be on
local disk, FC SAN, HP SVSP, and iSCSI.
• HP recommends the following iSCSI targets as backing storage for virtual machine guests:

◦ Other iSCSI targets certified and supported by the storage vendor and Microsoft Hyper-V
and VMware ESX and ESXi.
For more information, see the HP Insight Management Support Matrix.
• For VMware environments, Matrix OE also supports hypervisor file systems on NAS and virtual
machines using RDM to access a FC LUN directly. RDM is a key enabler to allow a logical
server to move from a physical environment to a virtual one while still accessing the same
boot and data volumes.
• For Integrity Virtual Machine environments, Matrix OE supports the use of SLVM (Shared
Logical Volume Manager) volumes or physical FC disks.
Storage types
Physical (server with Virtual Connect and Operations Orchestration workflow) logical servers use
storage provisioned from the SAN. Virtual machine logical servers use storage from the file system
of the VM Host.
Logical server storage types are:
SAN Storage Pool Entry Requires that you manually enter the storage port WWN
and LUN identifier corresponding to the server WWN for
each storage volume.
SAN Catalog Storage Entry (Server
with Virtual Connect logical servers
only)
Allows you to select storage that was preconfigured in HP
Storage Provisioning Manager. Dynamically presents
volumes to user specified server WWNs.
