The latest version of EMC’s disk library for mainframe is designed to ease the growth pressure created by so-called “third-platform” applications. The library, DLm 4.3, leverages two concepts for virtual tape libraries (VTLs): storage choice and virtual provisioning. DLm has deduplication storage based on EMC Data Domain, storage based on EMC VNX, and universal data consistency based on EMC VMAX. Enhanced features include boosted storage density, VTL capacity up to 3.1PBs, and enhanced data protection and D/R testing.
“Outside of mainframe operators, few people using enterprise applications today have even a vague idea that mobile applications drive enormous amounts of data back to mainframes, increasing demands on storage as well as pushing the limits of physical tape systems that tie back to mainframes,” said Greg Gotta, vice president of the enterprise and midrange systems division at EMC. “The link between first platform infrastructure and third platform applications is important to a myriad of enterprise applications.”
Just as important is the link between tape applications and EMC’s Disk library for mainframe (DLm that is designed to ease the growth pressure that third-platform applications are creating for the mainframe. “Seven years ago, EMC improved traditional data protection for the mainframe with high-density disk-based systems to displace tape-based backup,” said Gotta. “We’re pushing this value proposition even further with DLm 4.3, leveraging two unique concepts for Virtual Tape Libraries: storage choice and virtual provisioning.”
According to the vendor, DLm has deduplication storage based on EMC Data Domain, fast storage based on EMC VNX, and universal data consistency based on EMC VMAX.
Storage density in the new DLm systems is being boosted by up to 85% via 4TB drives and virtual provisioning. These enhancements enable a capacity improvement of up to 41%, allowing users to create the largest VTL capacity available in a single system today – up to 3.1PB – while maximizing overall DLm performance for applications such as online image retrieval that require fast response times.
Dlm 4.3 also leverage advancements in EMC Data Domain, intended to simplify the configuration of protection storage for mainframe, supporting both the DD 7200 and new DD 9500 systems.
