Network and Storage Planning
Storage Overview and Terminology
The NAS 8000 is an easy-to-manage storage solution for heterogeneous environments
including Windows, UNIX, and Linux.
The storage space on the NAS 8000 is made up of physical and logical storage:
In addition, the HA configurations include high-availability features such as redundant
hardware and failover packages.
Physical Storage
Storage Arrays
The NAS 8000 configurations can access storage on a variety of devices within a SAN device,
including the HP Virtual Array 7100 and 74xx series, and HP XP series disk arrays using
SecureManager VA or SecureManager XP. The HP NAS 8000 also supports connection to the
EMA array. Contact your local sales representative for more details.
HP Secure Manager Virtual Array is an array-based software product that allows LUNs to be
locked into secure protected volumes by World Wide Names (up to 128 secure World Wide
Name connections per virtual array), ensuring that only authorized World Wide Names
(WWN) have access to restricted volumes.
Logical Storage
SAN
A SAN, or Storage Area Network, is a high-speed special-purpose network (or subnetwork)
that connects different kinds of storage devices with associated data servers on behalf of a
larger network of users. Typically, a SAN is part of the overall network of computing resources
in a company. SAN devices are usually close to other computing resources, but may also
extend to remote locations for backup and archival storage. NAS 8000 SAN solutions can
access storage on supported devices within the SAN.
SecureManager VA or XP maintains LUN level security so that the storage given to the NAS
Server is not used by other servers connected to the storage pool. See
page 12. For EVAs and EMAs, you can maintain security by using HP StorageWorks
SecurePath.

arrays in an HP-approved SAN topology.
Logical Unit Number
A logical unit number (LUN) is a logical aggregation of space on physical drives. LUNs are
unique identifiers that enable the controller to differentiate between separate devices (each of
which is a logical unit). Each LUN is a unique number that identifies a specific unit of storage.
The NAS 8000 supports up to 128 LUNs.

Physical storage refers to the hardware you use for data storage.
Logical storage is created by software that organizes your physical storage into file
volumes and directories that are made accessible to users.
HP does not currently support third party storage products — only EMA, EVA, VA, and XP
