Storage Management Overview; Storage Management Process - HP StorageWorks 4000s - NAS Administration Manual

Storage Management Overview

The NAS server is configured at the factory with default system settings and with the NAS
operating system installed. No external addressable storage is included with the NAS device.
Storage is based on the SAN infrastructure and is configured using the appropriate tools for the
particular SAN storage arrays in use.
This chapter defines and discusses physical, logical, and snapshot storage concepts on the HP
StorageWorks NAS server.
Additional storage management information is included in the following chapters:

Storage Management Process

The lowest level of storage management occurs at the physical drive level. Physical drives are
grouped into arrays for better performance and fault tolerance.
The arrays are then configured with RAID fault tolerance and presented to the operating
system as logical drives or units, which are called LUNs.
At the virtual level of storage, the WebUI is used to take the LUNs and create basic or dynamic
disks, which can then be broken down into partitions or volumes. Folders, subfolders, and file
shares are created on the resulting volumes or partitions to organize, store, and give access to
the data. The Shadow Copy support is used to create snapshots of the data at specific times.
For organizational and documentation purposes, this administration guide separates physical
storage from logical storage.

and the associated Array Configuration Utility are used in the example. The Array Storage
device in use will impact the devices in use and the relevant storage management software
required.
