EMC unveils new DLm8000 Disk Library

PrintEMC Monday unveiled a high-capacity mainframe disk archive based on its flagship VMAX Symmetrix storage array.
The new DLm8000 Disk Library follows three earlier versions of "disk libraries" or disk archive arrays - the DLm1000, DLm2000 and DLm6000. The earlier disk libraries were built using either EMC's Data Domain virtual tape library or its midrange VNX storage array.
EMC's disk libraries appear as tape libraries to mainframes, but offer superior performance, particularly for data recovery.
All four EMC disk libraries can be managed through the same management interface.
Like EMC's smaller libraries, the DLm8000 offers RAID 6 protection, so that up to two hard drives can fail without the loss of data. The array also offers deduplication and hardware-based data compression capabilities.
The DLm8000, which is expected to be available in the fourth quarter, can replicate data over IP from a source mainframe to one or two remote sites. Users can replicate part of all of their tape backup data, choosing what data has recover priority.
The new disk library offers up to 1.8 petabytes of storage capacity or 6PB of capacity with deduplication and compression.
Besides an increase in capacity, the new DLm8000 introduces -- for the first time -- synchronous replication via EMC's Symmetrix Remote Data Facility (SRDF). Data can be replicated over distance continuously to a secondary data center or disaster recovery site.
"Data consistency becomes key, especially for customers that measure the cost of downtime with each transaction in tens of thousands of dollars," said EMC's Rob Emsley, a senior director of product marketing at EMC.
