Pressure eased off of grid storage
Nov 9th, 2004: A new grid storage system has been released that requires less overall management because of the high level of integration it offers for data recovery, archiving and replication operations.
ExaGrid Systems has unveiled Advanstor which saves on resources by only backing up changed files, which is very different to traditional backup systems that end up replicating too much of the same static data.
Advanstor runs on a redundant network of Intel servers with serial ATA drives that can operate as either NAS devices or disk storage to allow the administrator to view a virtualised pool of the capacity.
Administrators can create shares and restore files or entire directories to a previous point in time. Shares of data can be migrated to new filters in order to recover from site disaster or to balance the client/application load among additional grids.
Each grid disk can be configured and customised by the user to the number of NAS devices and storage disks that are necessary.
Advanstor uses InfiniteFilters, to provide customers with high-performance NAS-based primary storage capacity. These InfiniteFilters have the ability to automatically maintain less active data within lower-cost repositories.
The repositories also contain historical backup data for both local and offsite InfiniteFilters, so, in the event of a site disaster, the replicated backup data in surviving repositories is used to quickly recreate the contents of the InfiniteFilters that were damaged or lost in the site disaster.
Inside each InfiniteFiler share, a unique protection policy can be created which defines how, when and were data for that share should be protected across a local and an offsite repository.
In addition, Advanstor software running in each repository guarantees long-term preservation of data and restore of lost files through continual file-level data integrity checking and the correction of lost or corrupted files.
