EMC Addresses Surging Backup Demands

EMC's latest storage additions to its backup lineup include a refresh of its top-end Data Domain 800 family, a new high-end deduplication solution, and what EMC calls the industry's first long-term retention system for backup and archive. Unveiled on Tuesday, the new systems are part of a series of announcements from the storage powerhouse.

Quoting recent Gartner research (User Survey Analysis: Key Trends Shaping the Future of Data Center Infrastructure Through 2011, A. Adams, N. Mishra, Oct. 22, 2010), EMC says that over 60 percent of large enterprises will be investing in data archiving or retirement by the end of 2011, and that existing tape and disk-based systems may not have the backup throughput or deduplication capabilities to make a meaningful difference in the way users deal with these challenges concurrently.

EMC says that the Data Domain DD890 and DD860 single controller systems provide up to 8 times the throughput of competing solutions, up to 14.7 and 9.8 terabytes per hour, respectively, and logical capacity of up to 14.2 petabytes and 7.1 petabytes, respectively. EMC has also added native support for the IBM i operating environment to the Data Domain line, enabling network-based disaster recovery and simultaneous protection for IBM i and open systems environments on a single Data Domain system.

The DD890 replaces the DD880, while the DD860 replaces the DD690. EMC says customers with a number of the older DD models can upgrade to the new capabilities just by swapping out the older controllers. Incorporating two of the new DD890 controllers, the EMC Data Domain Global Deduplication Array (GDA) is more than 7 times faster than its dual-controller competitor and now supports the EMC Data Domain Virtual Tape Library software option, which expands the number of supported backup applications, including IBM Tivoli Storage Manager (TSM). Throughput is up to 26.3 terabytes per hour (7,300MBytes per second), and logical capacity is up to 28.5 petabytes.

EMC says it is breaking new ground with the Data Domain Archiver, bridging the gap between backups retained as archives and the dedicated archive processes. The company acknowledges that tape is not dead but that, increasingly, customers are looking for archiving alternatives, hence the new product.
