Exanet tackles grid storage
The 2.0 version of Exanet's ExaStore Grid Storage software, which is based on the company's ExaMesh grid architecture, clusters storage resources (including RAID arrays, servers/controllers, and cache memory) into a unified storage resource with a single name space via a global file system. The network-attached storage (NAS) architecture supports the NFS, CIFS, and AFP (Apple File Protocol) protocols for data/file sharing. The system manages the consolidated storage environment with dynamic capacity, performance load balancing, and distributed cooperative caching to eliminate performance bottlenecks.
The system's user access management supports authentication mechanisms such as NIS+, NT Domain Controller, and Active Directory, as well as internal authentication mechanisms. For safe resource and file sharing, ExaStore uses a distributed locking mechanism. Also included in the software is a quota system that allows storage space management, tracking, and enforcement of capacity usage policies across all protocols. The software works with off-the-shelf servers and RAID arrays.
Separately, Exanet announced a reseller agreement with Kodak Polychrome Graphics under which KPG will resell ExaStore in the graphics arts and digital content markets. www.exanet.com.
Xtore ships FC-SATA array
