HP NAS 8000 Overview 9
HP NAS 8000 Overview
What is NAS?
Network-attached storage (NAS) is a storage solution attached to a network
that is optimized for file sharing and serving. NAS provides a simple,
reliable, and cost-effective way to add storage to networks. Because a NAS
device is designed specifically for storage, it requires minimal setup and is
easily maintained. NAS devices also have built-in redundancy features to
protect against failure and downtime.
A NAS solution typically consists of a server, a set of disk drives, a custom
operating system, and a built-in web interface for managing storage. NAS
devices provide file services to a mixture of clients that operate in a
heterogeneous network environment. A NAS device can be added to an
existing LAN network to increase storage capacity.
How is NAS different from SAN (Storage Area Network)? In many respects
they are similar and can use the same hardware, but the SAN requires its
own high-speed storage network, while the NAS lives on an already existing
LAN. A NAS device is designed to move files, whereas the SAN is designed
to provide block-level data at high speeds to application servers. SAN
solutions are typically more difficult to implement and more expensive than
NAS solutions.

10 HP NAS 8000 Overview
Product Overview
The HP Surestore Network-Attached Storage (NAS) 8000 series offers several
storage solutions that attach directly to your network and provide shared file
storage for workgroups and departments.
Hardware
The NAS 8000 solution can include one or more of the following, sold
separately or pre-installed in a rack:
■A NAS server with a custom operating system.
—Network interface cards (NICs). The server comes with one 10/100TX
port, and you can add up to two dual-port 10/100TX NICs or two
single-port gigabit NICs.
■Storage arrays:
—Direct-attached to the NAS server. The HP Virtual Array (VA) 7100
and 7400 series can have up to 15 drives (18, 36 and 73 GB
capacity); the VA7400 series supports up to six JBODs attached to
each array for additional storage capacity.
—Remotely connected via a SAN network. HP VA and XP arrays are
supported.
■Fiber channel switches for multiple array configurations.
■Quorum server with cluster management software for high-availability
solutions.

Figure 1 NAS Racked System
Other accessories sold separately are:
■Uninterruptible power supply (UPS).
■HP Surestore tape libraries.

12 HP NAS 8000 Overview
Software
The NAS 8000 server comes preloaded with:
■A custom operating system optimized for file serving. A command line
interface is available for advanced server management.
■HP Command View NAS management software that runs in a web
browser. This graphical user interface is the primary tool for managing the
NAS 8000. Links to Command View SDM are provided for advanced
array management.
■HP Virus Guard virus protection software, which is integrated with the
NAS operating system and Command View NAS.
■A server backup agent for HP OmniBack II 4.1, which is integrated with
the NAS operating system and Command View NAS.
■File volume snapshot capability for data protection.
If you do not use the NAS 8000 backup agent, you can backup your data
using one of the following network backup software products:
■HP OmniBack II
■Computer Associates ARCserve 2000
■Veritas Backup Exec
■Veritas NetBackup
■IBM Tivoli Storage Manager
■Legato Networker
You can also integrate the NAS 8000 with several network management
software products, including HP OpenView Network Node Manager. For
more information about network management plug-ins, see http://
www.hp.com/support/emsp to learn about the HP Surestore Enterprise
Integrations product.
Additional NAS 8000 integrations with other products, such as Oracle and
SQL server may be possible. See http://www.hp.com/support/nas8000 for
a current description of supported product integrations.

Product Configurations
The NAS 8000 is available in four configurations:
■Direct-attached storage configuration
■Direct-attached storage configuration with high availability
■SAN configuration
■SAN configuration with high availability
Depending on the configuration of your NAS server, different options display
in the Command View NAS web interface.
Direct-Attached Configuration
With direct-attach configurations, one HP VA7100 or VA7400 series disk
array is connected to the NAS server using one Fibre Channel (FC) Host Bus
Adapter (HBA). In addition:
■The server includes one internal NIC with the option of adding two
additional NICs.
■The server may include two SCSI or FC HBAs for connecting to an optional
tape library.
■The server communicates with an optional UPS using a serial connection.

Figure 2 Direct Attached Configuration
Direct-Attached Configuration with High Availability
In direct-attached configurations with high availability, one or two VA7100
or VA7400 series disk arrays are attached to a cluster consisting of two NAS
servers and a Quorum server that manages the high-availability services for
the cluster. In addition:
■A single HBA is pre-installed in each server.
■A separate UPS is required for each NAS server.
■Tape backup can be shared by both NAS servers.

SAN Configuration
NAS 8000 solutions can also manage storage on HP VA7100, VA7400
series or XP model arrays connected to a SAN. LUNs must be created and
assigned to the NAS 8000 using a product such as HP Surestore Secure
Manager VA or Secure Manager XP.

SAN Configuration with High Availability
A high-availability, clustered NAS 8000 system can also be configured to
access VA7100, VA7400 series and XP model arrays attached via SAN.
