Start-up Makes SAN out of Servers

InfoStor writes: 

Seanodes has entered the storage industry with a novel approach to creating high-performance virtual storage pools from the unused storage capacity found in application servers.

The company’s software, called Exanodes, is based on a Shared Internal Storage architecture that reclaims existing storage resources to build a self-healing, self-organizing, storage infrastructure. Each node is capable of functioning as both an application and storage server, eliminating the need for dedicated storage servers.

An Exanodes cluster can accommodate 128 nodes and interoperates with any block storage device, disk drives, solid-state disk (SSD), RAID, and external DAS. The software allows for sustained read-or-write performance of several gigabytes per second and enables large numbers of internal disks to be managed as a single shared storage pool.

Exanodes also supports fast RAID rebuilds by distributing the RAID set across multiple network nodes so that, according to company claims, 1TB of data can be rebuilt in less than one hour, minimizing the risks of a second disk failure during the rebuild window.

The software can reclaim storage on Linux-based servers, with Windows compatibility expected later this year. Seanodes is also in the process of developing a similar product for virtual machine (VM) environments.
