HP Matrix Operating Environment 7.3 and 7.3 Update 1 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 LUN access by virtual machines (termed RDM (Raw Device
Mapping) for VMware and Disk Pass-Through for Hyper-V). This is necessary for
cross-technology logical servers.
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.
NOTE: When creating logical servers from Matrix OE visualization, local disk is not supported.
However, if using Matrix infrastructure orchestration, there is a mechanism for local disk support
via manual file edits to provide local disk information. See “Modifying physical servers with local
disk information” (page 75) for more information. HP recommends logical servers with operating
system booting from SAN, and data disks in the SAN (for maximum flexibility as the logical server
moves from one Virtual Connect system to another).
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, SAS, FC SAN, Flat SAN (direct connect to HP 3PAR StoreServ), and iSCSI.
• For specific details of storage support for VM environment, see “VM guest storage options ”
(page 26) and Insight Management Support Matrix at www.hp.com/go/matrixoe/docs.
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 or raw LUN access.
Logical server storage types are:
SAN Storage 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 pre-provisioned and
imported into HP Storage Provisioning Manager, or will be
on-demand provisioned by SPM. SPM can dynamically
present volumes to user specified server WWNs, and
perform automated zoning in Brocade SAN environments.
Use this storage type to ensure that SPM pre-provisioned or
on-demand provisioned storage will be used.
SAN Pre-populated Catalog Storage
Entry (Server with Virtual Connect
logical servers only)
Allows you to select storage that was preconfigured in HP
Storage Provisioning Manager. All volumes are already
presented to WWNs, and the WWNs are displayed with
the volumes. Add a volume, select a candidate for the
volume and a storage port WWN, and the rest of the
information is filled in automatically.
