Avere introduced global namespace functionality today with the release of the 2.0 version of its operating software. The software runs on the company’s line of solid-state FXT appliances, which provide automated tiering and acceleration for heterogeneous NAS filers and allow users to independently scale performance and capacity (see related articles below).

“A global namespace allows IT administrators to create a single logical view and a single mount point for heterogeneous physical filers,” says Ron Bianchini, Avere’s president and CEO.

Avere’s FXT appliances, which can be clustered, communicate via NFS or CIFS on the front end, and via NFS on the back end. The appliances work with any NAS systems, and accelerate NAS performance by leveraging DRAM, NVRAM and solid-state disk (SSD) drives. Most-frequently-accessed files are storage on solid-state devices, while infrequently-accessed files are storage o the filer’s SAS or SATA drives.

Although a variety of vendors offer global namespaces, most implementations are confined to homogeneous environments.

In addition to providing a single view of all NAS resources, the global namespace functionality allows newly added exports to be visible to clients without the need for client reboots.

The global namespace physical view is auto-populated on Avere’s user interface, while the global namespace logical view is user-defined in the user interface.

In November, Avere introduced the 1.4 release of its operating system, which included bi-modal CIFS ACL support, parallel file access, and increased number of back-end connections (up to 24) to NAS filers (see “Avere Systems speeds up tiered NAS appliances” on Enterprise Storage Forum).
