EMULEX MODEL 375 SAN STORAGE SWITCH

USER’S GUIDE CHAPTER 1: INTRODUCTION

EMULEX CORPORATION 5

ART NUMBER 00041369-002 REV. B

Figure 1-2 depicts a sample multiple switch storage consolidation configuration in which multiple servers

communicate with storage devices and zoning is incorporated. The zoning in Figure 1-2 might be set up

to configure a multiple operating system environment. For example, Zone 1 might be Windows-based,

Zone 2 might be Linux-based, and Zone 3 might be Unix-based. Zoning can also be used to improve

security by masking storage devices or files. For example, a finance department could secure financial

files from viewing by the engineering department, which in turn could secure engineering files from

viewing by the finance department.

Tape Library Consolidation

Another switch application is the consolidation of multiple tape libraries attached to individual servers

into a single library for all servers for backup and restore purposes.

Benefits include:

• Improved cost effectiveness.

• Improved availability for performing system backups:

• Off-LAN System Backups often reduce the amount of time it takes backups (and

recovery) to occur because SANs run at higher performance bandwidth than LANs.

• Server-less backups enable applications to remain fully active during backup and

recovery processes, when combined with the appropriate backup software solution.

Figure 1-3 depicts a sample tape library consolidation configuration.

Figure 1-3: Before consolidation, backup and restore data must

travel on the LAN, congesting traffic and operating at slow

speeds.

Figure 1-3: After consolidation, backup and

restore data travels on the high speed SAN

separate from LAN traffic.
