ExaGrid offers bigger backup systems, storage grids

By Kevin Komiega

-- ExaGrid Systems today launched a 10TB deduplicating disk-based backup system and expanded the maximum size of its storage grid to 100TB.

Taking its place at the high end of ExaGrid's product line, the EX10000E is a 4U rack-mount server with a maximum capacity of 10TB, doubling the size of the company's previous high-end backup appliance.

According to ExaGrid's vice president of product management, Marc Crespi, a fully configured grid with EX10000E systems delivers backup throughput of up to 18TB per hour with restore throughput of up to 14.4TB per hour.

ExaGrid's software architecture pools the backup systems – available in 1TB, 2TB, 3TB, 4TB, 5TB, and now 10TB capacities – into a storage "grid" that presents itself to a backup server as a single system, load-balancing data along the way. Each grid is also capable of moving byte-level changes to an offsite location for disaster recovery.

In conjunction with the launch of the EX10000E, ExaGrid is now offering a software upgrade that enables the creation of a backup grid consisting of 10 servers (up from the previous limit of 8) for a maximum grid size of 100TB.

ExaGrid takes a post-processing approach to data deduplication. The company's byte-level data deduplication technology reduces the disk space required by at least 10x.

ExaGrid plans to ship the EX10000E by month's end. List pricing for a 10TB EX10000E with all-inclusive software is $85,900. The only piece of the system that carries an extra fee is optional 10 Gigabit Ethernet (GbE) connectivity.

Customers already using ExaGrid's products can expand their existing grid to 10 servers with 100TB maximum capacity for no charge as part of their current maintenance and support contracts.

ExaGrid's backup systems work in concert with a range of popular backup packages and data protection tools, including CA ARCserve, CommVault Simpana, EMC Networker, Linux/Unix dumps, Microsoft SQL dump, Oracle RMAN dumps, Symantec Backup Exec, Symantec NetBackup, Vizioncore vRangerPro, and VMware Backup.
