Virtual Storage Pool, Seanodes New Offering
French startup Seanodes, inventor of the shared internal storage concept (SIS), has introduced a new product to combine storage on many Linux servers into a single shared pool of storage, making networked storage unnecessary.
Seanodes’ new Exanodes software runs on each Linux server and adds its unused direct-attached storage (DAS) into a Shared Internal Storage (SIS) pool which acts, in IDC's term, as an inside-out SAN. This is viewed by applications as a traditional external shared array and can be either implemented alone or as a complement to existing external storage (SAN or NAS).
The individual servers are clustered together and the nodes can act both as application and storage servers. A 32-node Exanodes cluster has delivered 2.3GB/s throughput. Exanodes provides file systems with storage volumes (logical unit number or LUN) accessible in block mode.
"The concept and benefits of an inside-out SAN are pretty obvious once you see them. All the aggregate formatted capacity is available to all the application computers. No stranded capacity exists and there is no single point of failure, since mirroring across computer systems would be employed," said Laura Dubois, IDC's storage software program director.
“When VMware aggregates, organizes and consolidates CPUs in application servers, Exanodes aggregates, organizes and consolidates storage devices in application servers,” said Frank Gana, director of business development at Seanodes.
Exanodes works with any block storage devices, hard disk drives, SSD, RAID and external DAS and is the only any-to-any connect shared internal storage software on the market today. The ECA (French Atomic Energy Commission) is a user of the product. A SIS product for a virtual machine environment is currently under development as is a port of the software to Windows.
Gana was unwilling to provide pricing information, and said: "We do not want to commit exactly on the price." It depends upon the number and type of application and storage servers and the capacity of the storage involved. He said it was lower, very much lower, than an equivalent amount of traditional networked storage
