EMC Corporation DD880 single controller system capacity doubled

EMC Corporation has announced that the Data Domain DD880 single controller system for large enterprises has now doubled its maximum capacity, offering support for up to 7.1 petabytes of logical storage. This provides users with greater backup and disaster recovery consolidation, further simplifying management and reducing operational expenses.

Administrators can use the additional capacity to consolidate up to 180 concurrent backup jobs or extend the retention period when used as a replication target for up to 180 remote offices. The increase in capacity further minimises the physical footprint, power and cooling required to protect large data sets in primary data centres and in DR sites.

EMC has also introduced Data Domain Encryption software, claimed to be the first data at rest encryption for deduplication storage systems, enabling organisations to enhance the security of their data and more easily pass security audits. The software integrates with the Data Domain high-speed, inline deduplication process and provides administrator-selectable 128- or 256-bit Advanced Encryption Standard algorithms for encrypting all data before it is written to disk. With an inline approach, data never resides in a vulnerable, unencrypted state on the disk subsystem. This capability works with all Data Domain protocols and software options and can be used with DD Replicator to send encrypted data over the WAN. Files that are retained on disk in a non-rewriteable and non-erasable format, as a long-term archive using Data Domain Retention Lock software, can also be encrypted.

The Data Domain Replicator software now includes a ‘one-to-many’ directory replication topology which enables users to send multiple copies of source system data to different DR sites. This delivers increased protection levels and gives the administrator the ability to reliably and efficiently replicate the same content across a distributed enterprise for QA, testing, development, training and other uses.

For small systems replicating to larger hub systems across low bandwidth networks, the software can further reduce the amount of data to be sent using a new low bandwidth optimisation feature. This enables further reduction of the Replicator bandwidth, which already sends only deduplicated, compressed data, by up to 100%, leveraging an additional new delta compression technology. The introduction of both a ‘one-to-many’ replication topology and low bandwidth optimisation further demonstrates EMC’s ability to deliver the most flexible, feature-rich and network-efficient multi-site disaster recovery solutions for backup and archive data. These features are included with the latest version of DD Replicator software. Data Domain system users that have purchased DD Replicator licences and have an existing support contract can upgrade to this version for no extra charge.
