ExaGrid Unveils New High-End Backup Appliance
November 19, 2013 Alex Woodie
ExaGrid last month unveiled its biggest backup appliance yet, the EX21000E, which holds can hold up to 210 TB of full backups when 10 of them are linked together in a grid. And thanks to a partnership with LaserVault, pushing backups from the IBM i server doesn’t involve weird Linux commands or expensive IBM backup software.
ExaGrid makes disk-to-disk (D2D) appliances designed to address the backup and recovery needs of midsize organizations with growing data storage needs. The company says its horizontally distributed scale-out architecture gives it an advantage over other architectures that require forklift upgrades to expand capacity.
According to the ExaGrid EX spec sheet, the new EX21000E device can hold up to 21 TB of backup data each. Up to 10 of the devices can be linked in a grid, providing the capacity to hold full backups that are up to 210 TB in size. The EX21000E also features an ingest rate of 4.32 TB per hour, which increases to an ingest rate of 43.2 TB per hour with 10 appliances in a GRID, the company says.
The new EX21000E offers more than 50 percent more storage capacity than the EX13000E, its previous top-of-the-line storage device, and much faster speeds as well. Even if a user has that device, or any of the other dozen or so devices, they can simply add the new EX21000E into the mix, and keep right on backing up, de-duping, and encrypting data. “Our scale-out architecture has no theoretical limits. It can handle any amount of data,” says ExaGrid CEO Bill Andrews in a press release.
ExaGrid’s Lintel-based appliances use industry standard components, including SATA drives and Gigabit Ethernet ports, and appear as NAS resources for Windows, Linux, and Unix environments. For IBM i environments, ExaGrid offers three ways to get at the data. Its first attempt at IBM i support, made in 2010, used the Qshell and TAR Linux utilities, which few IBM i professionals are probably familiar with. Its second attempt, made in 2011, used Tivoli Storage Manager (TSM), which is even more obscure to regular IBM i shops.
The third and by far best approach to hooking up an ExaGrid machine to an IBM i server leverages the LaserVault Backup (LVB) application, which implements native IBM i backup commands. For more information, see www.exagrid.com
