Data Domain Boosts Enterprise Disaster Recovery
May 2009 by Marc Jacob
Data Domain, Inc., the provider of deduplication storage systems, today announced new feature updates to the Data Domain Replicator software option that increase global fan-in support and throughput for enterprise disaster recovery (DR). Data Domain Replicator software now supports up to 90-to-1 remote site fan-in to a single controller for automated global deduplication. This capability provides differentiated, enterprise-ready deployment flexibility across policies and topologies, along with network management options such as replication scheduling and WAN resource throttling. Data Domain Replicator also now supports highly optimized, full system replication mirroring to offer the simplest and fastest end-to-end throughput from backup ingest through restore from the replica site for deduplication storage.
Data centres and large enterprises are looking to deploy ultra-reliable, disk-based backup/restore solutions with automated, multi-site DR capabilities. Most enterprise deployments of Data Domain systems include its Replicator software, which enables the rapid transfer of optimized data over low-bandwidth WAN links to simplify and accelerate DR readiness while reducing WAN costs. The combination of high speed inline deduplication, global deduplication and simultaneous vaulting of data offsite means fast time-to-DR for Data Domain users.
Unlike other storage products with deduplication and replication, Data Domain offers enterprise users unique data protection advantages:
A single DD690 enterprise system can now support replication fan-in from up to 90 remote sites, deduplicating globally. This means a fully configured DDX Array now supports up to 1440-to-1 fan-in, enabling deployment for very large distributed DR deployments.
A pair of Data Domain systems across a WAN can now be full system mirrors at high speed, replicating all system-wide changes across multiple input protocols just after inline deduplication storage, so files can be restored from the replica as soon as possible after being backed up. This comprehensive and rapid mirroring at the logical level means even large systems in enterprise data centre deployments, with hundreds of millions of files, can synchronize recovery data to a DR site with low WAN bandwidth, low system overhead and high speed. This enables wire-speed transfer of deduplicated and compressed data on a 1 Gb Ethernet link, for up to 21 TB/hour of backup image transfer throughput.
Data is instantly visible and restorable from the Data Domain replica with no operator or script intervention. Replicator is part of the integrated design of the Data Domain file system, so once data transfers to a destination site, the replica is continuously consistent.
Replica system restore speed can be up to 15x faster than competitors’ restore rates from the dedupe pool on their replica, as observed in customer deployments.
Automated compression for WAN optimization. Unlike some competing products which replicate data that is deduplicated but not compressed, and can result in half the throughput and require up to twice as much time to replicate on the same bandwidth link, Data Domain both deduplicates and compresses data prior to transfer across the WAN.
Robust integrated management functions, such as replication scheduling and WAN resource throttling.
Large Data Domain Enterprise Customers Share Successful Replication Experiences
Orange County Public School System is the 11th largest district in the U.S. with 177 K-12 schools serving about 175,000 students. The school system is the second largest employer in Central Florida. A Data Domain customer for two years, the district’s IT department has deployed 10 deduplication storage systems to protect its enterprise application data including SAP, Microsoft SQL, Exchange and Oracle databases. The department also backs up its mainframe system through LUMINEX Channel Gateways to Data Domain. The district utilizes Data Domain Replicator for high-speed mirroring of five Data Domain systems in its primary data centre to five replica systems located at the district’s disaster recovery facility.
Teck Resources Ltd. is Canada’s largest diversified mining company, with major business units focused on copper, metallurgical coal, zinc, gold and energy. The company’s IT department is successfully standardizing its infrastructure to consolidate its primary data centres, and to create uniformity and auditability across the company’s expanding tier 1 (production sites) and tier 2 (exploration and remote sites).
Data Domain deduplication storage systems offer easy integration by supporting leading enterprise backup and archive applications as well as a variety of transfer protocols simultaneously, including CIFS or NFS fileserver, a Virtual Tape Library (VTL) with Fibre Channel and the Symantec Veritas NetBackup OpenStorage (OST) interface.
– Pricing and Availability: Data Domain Replicator software is available today. Pricing starts at €1,845 / £1,645 / $2,450.
