370 iSeries Handbook
– Backup/archive
– Large sequential files
– Records management
– Multimedia applications
• New level of reliability and data integrity to the midrange environment and specifically
designed for:
– Repeated tape load/unloads
– Higher tape drive duty cycles
– Increased overall mechanical reliability
– Increased overall media reliability
• Increases the amount of data that can be accessed with near-online performance for
up to 4.8 TB of storage capacity (with a 3:1 compression ratio)
• Delivers an aggregate sustained data rate of 50 to 300 GB/hour with a maximum
compression on Model C tape drives
• Provides a rich multihost attachment for library sharing, up to six iSeries or AS/400e
hosts or any three heterogeneous hosts by partitioning the tape library into thirds
(1/3 + 1/3 + 1/3 or 1/3 + 2/3)
• Supports industry-leading storage management offerings to provide enterprise-wide
backup/restore and archive/retrieval
• Average cartridge move times in the Magstar MP 3575 tape library are less than 4.0
seconds, which complements the fast load/search time of the Magstar MP drive
• Magstar MP 3575 tape library is ideal for time-sensitive applications that require fast
access to data, highly I/O-intensive operations by multiple users, and traditional
save/restore operations
• Multicontrol path architecture
• Supports random mode
There are five models of the Magstar MP 3575 tape library, ranging in size from 420 GB to
4.8 TB of compressed online storage capacity and from one to six tape drives.
