EMC announced that it is released an update to its software for Disk Library for mainframe (DLm), version 4.3. The update includes significantly boosting the capacity of virtual tape libraries and enhancing data protection and disaster recovery testing. EMC’s new update is aimed at ease the pressure that Third Platform technologies are putting on mainframes.
Third Platform technologies (mobile, cloud, social media, Big Data, and the Internet Of Things) are making huge impacts on businesses. What surprises many in the technology field is how heavily certain Third Platform technologies relay on mainframes, or First Platform technologies. Third Platform technologies are driving a massive amount of data back to mainframes. This flow of data is putting a strain on mainframes and the physical tapes systems that they tie into. Mainframes still need support and upgrades as the struggle with growing workloads.
EMC improved traditional data protection for the mainframe with high-density disk-based systems to displace tape-based backup seven years ago. Today they are release DLm 4.3 that will further improve mainframes and Virtual Tape Libraries (VTL). This new update provides storage choice and virtual provisioning. DLm has storage based on EMC VNX, universal data consistency based on EMC VMAX and deduplication storage based on EMC Data Domain. DLm acts as tape but runs at disk speed.
Using 4TB drives and virtual provisioning, DLm will boost storage density up 85%. Capacity will be improved 41% enabling users to create the largest VTL capacity available in a single system today, 3.1PB. This will also help to maximize performance of applications such as online image retrieval. DLm can act as tape but mobile users can’t wait on tape-like responses times, DLm gives users the fast response times they expect.
DLm 4.3 uses the advancements in EMC Data Domain to simplify the configuration of protection storage for mainframe. EMC also added tape volume overwrite protection (WORM capability) for Data Domain-supported DLm deployments. Data Domain storage within DLm also includes automated disaster recovery tests. Now disaster recovery tests can be setup in DLm with a simple ISPF panel.
