Assumptions

MSA1500

• Uses SSP.
• Stores data with RAID. When using RAID Advanced Data Guarding (ADG), data is protected if two
disk drives should fail.

Tape library

An HP StorageWorks Enterprise Backup Solution (EBS)-supported HP StorageWorks MSL or HP
StorageWorks ESL model tape library is used.

Backup process

All backups are LAN-free over the Fibre Channel fabric.

Recovery process

Depending on which ISV is used and how the application is configured, the primary backup may or
may not be on disk. If staging is implemented, then after the policy parameters are satisfied, the
backup can be migrated from disk to tape. When the disk copy expires, the copy on tape becomes
the primary backup file.

Fibre Channel infrastructure

The SAN is operating correctly and is a known good environment before mezzanine storage is
implemented.

Design rules

• When using multiple hosts on the MSA1500, use SSP to protect LUNs. LUNs may not be shared, as
shared LUNs may result in data corruption.
• The MSA1500 can be configured with 32 LUNs. Best practices dictate no more than
20 servers accessing a single MSA1500.
• The NSR on the fabric should be zoned using host-centric based zoning.
