Lustre-based clustered file system maker Xyratex announced it will begin shipping its ClusterStor 3000 storage appliance for high-performance computing (HPC) applications during the fourth quarter.

Xyratex’s (NASDAQ: XRTX) Lustre-based ClusterStor 3000 provides a rack mountable clustered storage appliance that can be modularly scaled using what the company calls Scalable Storage Units (SSU), according to a company statement.

“ClusterStor’s scale-out storage architecture enables [construction of] configurations from terabytes to tens of petabytes and from 2.5 gigabytes per second to 1 terabyte per second of actual file system throughput,” the statement said. The ClusterStor 3000 can hold 1.5 petabytes of storage in a single rack, and takes less than four hours to set up, it added.

Xyratex’s ClusterStor 3000 combines Lustre servers with RAID controllers, and hard-disk drive (HDD) enclosures, items which are typically delivered as separate components, into SSUs that can be assembled as modular building blocks. Lustre is a Linux-based file system designed for HPC cluster use.

“As performance or capacity needs change, users can simply add incremental SSUs to the storage cluster and begin leveraging the increased performance and capacity immediately,” Xyratex’s statement said.

“Each SSU has up to 192 terabytes of usable Lustre OSS file system capacity and includes redundant server modules that operate and manage the SSU as a discrete scale-out component,” it added.

The system comes with ClusterStor Manager, which provides a single integrated administration console for provisioning, configuring, and monitoring the storage cluster.

Additionally, Xyratex has been working with the Lustre community to continue development of Lustre and has contributed to the Lustre 2.1 roadmap.

The ClusterStor 3000 is a product of Xyratex’s acquisition last year of ClusterStor, according to the company’s Storage Insights blog.

“We leveraged our core capabilities, in data storage subsystem design and the Lustre expertise we obtained in the ClusterStor acquisition last year, to develop an HPC solution that provides the best-in-class performance, scale out architecture and unprecedented ease of management,” the blog post said.
