System Overview Deployment Scenarios Various deployment scenarios are possible. See the HP StorageWorks NAS 2000s Installation Guide for configurations. Typical application of NAS devices include: ■ File server consolidation As businesses continue to expand their information technology (IT) infrastructures, they must find ways to manage larger environments without a corresponding increase in IT staff. Consolidating many servers into a single NAS device decreases the number of points of administration and increases the availability and flexibility of storage space. ■ Multiprotocol environments Some businesses require several types of computing systems to accomplish various tasks. The multiprotocol support of the NAS 2000s allows it to support many types of client computers concurrently. ■ Protocol and platform transitions When a transition between platforms is being planned, the ability of the NAS 2000s to support most file sharing protocols allows companies to continue to invest in file storage space without concerns about obsolescence. For example, an administrator planning a future transition from Windows to Linux can deploy the NAS 2000s with confidence that it can support both CIFS and NFS simultaneously, assuring not only a smooth transition, but also a firm protection of their investment. ■ Remote office deployment Frequently, branch offices and other remote locations lack dedicated IT staff members. An administrator located in a central location can use the WebUI of the NAS 2000s, Microsoft Terminal Services, and other remote administration methods to configure and administer all aspects of the NAS 2000s.

NAS 2000s Administration Guide

Deployment Scenarios

Various deployment scenarios are possible. See the

HP StorageWorks NAS 2000s Installation

Guide

for configurations. Typical application of NAS devices include:

■

File server consolidation

As businesses continue to expand their information technology (IT) infrastructures, they

must find ways to manage larger environments without a corresponding increase in IT

staff. Consolidating many servers into a single NAS device decreases the number of points

of administration and increases the availability and flexibility of storage space.

■

Multiprotocol environments

Some businesses require several types of computing systems to accomplish various tasks.

The multiprotocol support of the NAS 2000s allows it to support many types of client

computers concurrently.

■

Protocol and platform transitions

When a transition between platforms is being planned, the ability of the NAS 2000s to

support most file sharing protocols allows companies to continue to invest in file storage

space without concerns about obsolescence. For example, an administrator planning a

future transition from Windows to Linux can deploy the NAS 2000s with confidence that

it can support both CIFS and NFS simultaneously, assuring not only a smooth transition,

but also a firm protection of their investment.

Frequently, branch offices and other remote locations lack dedicated IT staff members. An

administrator located in a central location can use the WebUI of the NAS 2000s, Microsoft

Terminal Services, and other remote administration methods to configure and administer

all aspects of the NAS 2000s.
