—Exanet this week announced a new module for its ExaStore clustered NAS software, although it won't be available until the first quarter of next year. ExaStore ICM (Intelligent Cluster Management) integrates continuous data protection (CDP) software with a clustered NAS platform. The company also added capabilities such as automated storage management with virtual volumes.

CDP provides point-in-time functionality, which allows users to capture a virtually unlimited set of snapshots enabling a return to any recovery point. The CDP module captures block-level changes on a continuous basis and allows recovery from any point in time.

ICM's virtual volume capability will allow dynamic expansion or re-allocation of capacity relative to changing business needs and will give administrators the ability to restrict access to certain types of data by department or user. ExaStore's single file system and single storage pool are designed to maximize utilization of disk space.

ExaStore ICM is based on an architecture that works with standard, off-the-shelf hardware. It supports the NFS, CIFS, and AFP protocols, enabling file sharing between Apple, Unix, Linux, and Microsoft clients.

The ExaStore architecture virtualizes Intel-based servers and storage subsystems into a clustered NAS solution without vendor lock-in. The storage and server components of an ExaStore installation can be scaled independently on-the-fly, allowing users to tune the system to meet capacity, performance, and availability requirements.

Based on server nodes deployed in a clustered, high-availability configuration,
the ExaStore software architecture eliminates single failure points and minimizes downtime. The software is built around a distributed shared file system that enables administrators to manage an installation as a single NAS filer, regardless of how many nodes are deployed.
