RevStor revs grid storage engines

By Deni Connor

A storage start-up is launching this week that has put an interesting spin on grid computing and existing direct-attached storage.

RevStor, based in Schaumsberg, Ill., has taken commodity x86-based hardware and pooled its storage resources. The company’s product, SANware, groups the direct-attached storage from servers, laptops and desktops and makes their unused storage capacity available to users on the network.

In SANware, a software agent is installed on each machine in the grid. The software agent controls the node and allows it to take part in the grid. A node called a SuperNode controls the storing and retrieval of data for each group of 10 nodes.

While at present, RevStor only backs up file-based data to the grid of computers, a storage-area networking version will be available in the future. Network drives can also be added to the grid workgroup. As nodes leave the grid, their data is distributed to other nodes. As data changes, only the delta changes are added to the grid. Additionally to maximize disk space, compression is built in.

RevStor’s product looks similar to that of Seanodes, a company that also launched last week.

SANware runs on Windows, Linux, Unix or Solaris servers and is available for $3,500 per terabyte of storage. A Mac version is in the works. The company is self-funded.
