IBM has made some storage updates to increase array capacity, mainframe VTL performance, and data protection. The announcements seem to have got lost in the Storage Networking World announcement blitz taking place at Orlando in Florida.

DS4000 arrays now support 1TB SATA II drives.

The mainframe virtual tape library product (VTL), the Virtualization Engine TS7700 has new firmware which:-

- does load-balancing across a grid,
- allows host control over the copy of logical volumes on a cluster by cluster basis,
- has an option to gracefully remove an individual cluster from an existing grid,
- has initial-state reset for the TS7700 database for cluster cleanup,
- has an option to upgrade single-cache to dual-cache configuration.

The System p server 'media drawer' can now have DAT160 80GB drives or half-height LTO-4 drives in it.

The Productivity Center for Replication has added asynchronous disk mirroring support for the SAN Volume Controller (SVC) alongside the existing FlashCopy and Metro Mirror. It has also added bi-directional failover/failback.

The Productivity Center for Replication server can run on either a Windows/Linux-x86 server or a z/OS mainframe.

For the DS8000 drive array, IBM has added support for new Space Efficient FlashCopy and Dynamic Volume Expansion capabilities.

Thanks to IBM blogger Tony Pearson for this information.
