Jeff Greenwald, Senior Solutions Marketing Manager (Media and Entertainment) at BlueArc (, says:

Solutions are available today that can address pains associated with broader information governance challenges. Processes that are easily repeatable, and that are widely accepted as best practices for rapid investigative review can also be storage i/o intensive in their identification and collection.
BlueArc offers a highly scalable platform that removes bottlenecks, and enables high performance for building indexes for Electronically Stored Information. (ESI)
Reduced Risk
Know what data you have and where it is located Minimize data movement by processing and filtering in-place Define retention policies Service level agreements for storage
Reduce Cost
Use fewer tools to discover, collect and review Electronically Stored Information (ESI) Collection and hold in place, deliver only relevant material to the case Use storage automation features to minimize storage costs

Data that is retained for eDiscovery or placed on legal hold can leverage BlueArc’s Intelligent Tiering – the mixing and matching of storage tiers (SSD, SAS, and SATA) to achieve the optimal blend of performance, capacity and cost in an automated fashion. A BlueArc storage administrator can define two or more storage tiers to allow for automated movement of data between the optimized tiers based on a policy-based engine which allows data movement policies that match retention policies. This in turn, optimizes the total cost of the stored data, based on the optimized performance requirements for accessing these files.

Metadata attributes such as file type, file size, user or group ownership of file, last time of access, and dozens of other variables can be used to craft extremely effective data movement policies. Data movement may also be scheduled, running a policy check nightly, weekly, or monthly, or whatever time period best suits eDiscovery or legal hold requirements.
BlueArc’s Intelligent Tiering is transparent to end-users. All filesystem functions (e.g., snapshots, replication, quotas, etc.) work seamlessly as if the data were still on the original storage tier and data integrity is maintained during the migration or recall. As far as end-users and applications are concerned, the data has not moved at all. Users see the data as if it still existed in the original location, while BlueArc keeps track of where the data actually resides through the intelligent use of stubbing.
