EMC reveals virtual tape library for mainframes

The storage giant looks to tread on IBM's toes

EMC Corp. is looking to tread on IBM's toes after extending its virtual tape library (VTL) to cater for IBM's mainframe community.

The EMC Disk Library for mainframe (EMC DLm) is a virtual tape library system made for IBM's zSeries mainframes. EMC said that DLm will offer "high-performance disk-based backup and recovery, batch processing and storage."

Previously, EMC had brought in FalconStor's VTL products, but in September 2006 the storage giant concluded that VTL technology was important enough to own, and it went out and purchased the VTL assets of Neartek Inc.

Soon after in October 2006, EMC unveiled three new virtual tape products, and in May 2007 EMC introduced an enterprise-class VTL. Now EMC has moved the game upward into the mainframe arena, where it will compete with the likes of IBM and Sun Microsystems Inc.

The EMC DLm uses 1TB SATA II disk drives with RAID 6 protection. It comes in two configurations, namely with either two or four virtual tape emulators. It can scale to offer approximately 500TB of compressed storage capacity while delivering clock speeds of up to 600Mbit/sec. EMC said that this allows DLm to offer "33% greater throughput than competing mainframe VTLs."

Also, it connects directly to IBM zSeries mainframes using FICON or ESCON channels, and appears to the mainframe operating system as standard IBM tape drives.

There is no word of pricing yet, although DLm is expected to be made available next month.

EMC had no comment at press time.

Meanwhile, EMC also announced that it plans to update its continuous data protection product, RecoverPoint.

RecoverPoint 3.0 has an upgraded graphical user interface and has improved its connections to EMC's Clariion systems. It also has added some more options to its concurrent local and remote data replication bundle.
