EMULEX MODEL 375 SAN STORAGE SWITCH	CHAPTER 1: INTRODUCTION
USER’S GUIDE

Figure 1-2depicts a sample multiple switch storage consolidation configuration in which multiple servers communicate with storage devices and zoning is incorporated. The zoning in Figure 1-2might 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 1-3depicts 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.
