Storage Manager for Storage Area Networks
IBM Tivoli Storage Manager for Storage Area Networks extension allows SAN-connected Storage Manager servers and Storage Manager client computers to make maximum use of their direct network connection to storage.
This software extension introduces storage agents which allow both servers and client computers to make the bulk of their backup/restore and archive/retrieve data transfers over the SAN instead of the LAN, either directly to tape or to the Storage Manager disk storage pool. This ability greatly reduces the impact of data protection on the LAN while also reducing CPU utilisation on both client and server. For computers running Windows, some SAN configurations will allow specific SAN-devices to perform data movements directly to and from some tape devices, further reducing client and server CPU utilisations. Should a tape library be connected directly to a SAN, this software extension also allows multiple IBM Tivoli Storage Manager servers to share the library over this high-bandwidth data connection.
Tivoli Storage Manager for Storage Area Networks provides:
- LAN-Free backup / restore
Provides high-performance backup/restore. Minimises network traffic, improving application and transaction response times of the TSM server - SAN-Connected Tape Library
Allows library sharing where multiple servers can share a tape library and drives on a Storage Area Network - Server-Free Backup/Restores in Windows-Only Environment Minimises LAN network traffic, and CPU impact on Storage Manager servers and clients
Business Benefit:
- Reduced network traffic
- Increased data protection as data transfers are diverted from the LAN
- Reduced CPU impact on Storage manager servers through LAN-free backup/restore
- Improved application and transaction responsiveness
- Reduced storage cost and improved asset utilisation through library sharing
