Netbackup SSO

Backup over a SAN configuration

LAN-free backup solutions allow IT managers to move backup traffic off of congested IP networks and onto high speed dedicated fibre channel SANs.

Before the tape SAN implementation, the overloaded backup environment at Fair Isaac included:

• 20 DLT 8000 tape drives
• More than 3 TB per day full and incremental backups
• Hardware and tape failures, poor configuration
• Extensive manual intervention
• The need for improved reliability, improved throughput, and the ability to scale

To meet these needs, the project team organized a tape SAN architecture based on the following (see figure below):

• StorageTek PowderHorn 9310 Tape Library, with a 6000 tape capacity, controlled by StorageTek ACSLS software
• Eight StorageTek T9940A Tape Drives, with native Fibre Channel connectivity and 80 GB capacity (Since the project's completion, Fair Isaac has added four new StorageTek T9940A drives)
• VERITAS NetBackup DataCenter 3.4, with VERITAS NetBackup Shared Storage Option (SSO)
• Brocade SilkWorm 2800 Fabric Switches, with 16 ports each
• Sun Fire V880 Servers
• Sun Fire 280R Servers, clustered with VERITAS Cluster Server 2.0
• Largest database servers are attached to the SAN through 1 Gb fibre linking directly to the Brocade Fibre Channel switch fabric. Each server has an HBA.
• Remaining servers use common backup servers over Gb Ethernet or Ethernet 10/100, backed up through two common media servers
• NAS storage is backed up through centralized mounts to the media servers (see figure below)
