EMC Fields Disk-based Tape Drive Replacement System

By Stuart J. Johnston

Storage Giant EMC this week introduced an all-in-one virtual tape library (VTL) on disk system directed towards making virtually all backup and recovery tasks available from a single, integrated hardware and software configuration.

Called the DLm6000, EMC's (NYSE: EMC) next generation VTL is designed to replace the full range of mainframe tape workloads with a single, consolidated all-disk system, the company said in a statement.

Additionally, besides replacing tape drives and mainframe tape drive functions with an all-disk system that runs in IBM z/OS environments, the DLm6000 integrates EMC's VNX7500 unified storage system with EMC's Data Domain DD890 storage system.

"Use cases such as backup and recovery, batch processing, DFHSM (data facility hierarchical storage manager migration) and data archive have required mainframe users to implement multiple storage systems to support all of their tape workloads," EMC's statement said.

The result has, in many cases, been multiple systems with reliability and performance problems, multiple management consoles, and add-on functionalities such as disaster recovery and deduplication systems -- all of which cost extra.

EMC's DLm6000 also matches differing workloads to the most appropriate storage.

"By matching different workloads to the most appropriate storage, the DLm6000 maximizes system performance and accelerates data retrievals and backup and recovery times," the statement said.

The system provides throughput of 2 GBs per second, which EMC claims is twice the speed of its nearest competitor, and its logical storage capacity scales out to 5.7 petabytes.

All-in-all, the integration of various virtual tape backup systems, lowers costs ranging from hardware expenses to reduced electrical needs.

"The complexity of managing two or three separate platforms imposed by competing solutions is eliminated and reducing tape use removes a host of limitations that made it difficult for mainframe users to meet their SLAs for batch processing, backups and data access," Shane Jackson, vice president of marketing for the EMC backup recovery systems division, said in a statement.

EMC plans to ship the DLm6000 in September.
