"We needed a way to preserve this history in its native format for future generations," says David Ryan, the PRO's head of digital preservation.
The records office hired an outside contractor, Tessella, to help it build the new archive. Tessella picked FileTek Corp., Sun Microsystems Inc. (Nasdaq: SUNW), and Storage Technology Corp. (StorageTek) (NYSE: STK) to supply the various pieces of the puzzle.
FileTek's StorHouse hierarchical storage management (HSM) software will manage the digital files in a repository archived on a StorageTek L20 tape library; Sun will supply the servers. Data on the tape cartridges will be accessed through a Web interface, written by Tessella, that provides access and retrieval of requested information. FileTek's Relational File System (RFS) software will be used with StorHouse to archive hundreds of millions of files.
FileTek beat Sun to the software contract because its HSM product is easier to administer, according to Tessella. "PRO needed something simple, so we went with them over Suns SAM FS product," says Rob Sharp, senior software engineer at Tessella. On a related note, the Met Office, the British weather service, previously awarded a contract for similar software technology to FileTek to support its scientific research.
But back to the records office. If easy, fast access to the data is important, why not go for nearline disk storage? (See NetApp Has 100 NearStore Users, EMC Backs Clariion Into ATA, and FileTek Taps EMC Centera.)
