A petabyte-class holographic storage library will ship this year, following the signing of an OEM contract between technology and drive supplier InPhase, and DSM, an optical jukebox manufacturer based in Germany.

The library will use 300GB Tapestry media and drives, and provide high capacity archiving for the broadcast, government, medical, and large enterprise IT market. DSM customers including Deutsche Bank, ESA, Siemens Medical and Volkswagen.

Immo Gathmann, DSM's sales director, said: “Together with InPhase, we can address a corporate enterprise storage market that requires very high-capacity, petabyte-sized, storage."

"We can address new markets that have yet to move beyond tape back-up for critical data archive applications and we can also offer new ways of looking at partitioning RAID systems for this initial product which, at 300 GB, is very attractive for both near-line and deep archive asset retrieval functions."

"Currently a (DSM) TERASTORE 7600 with UDO 1 drives can hold up to 67TB. With the next UDO drive generation it will increase to about 134TB."

"The base unit for holographic drives can hold between 150 and 200 disks, depending on the number of integrated drives, i.e this unit provides a capacity between 45 and 60TB. There can be up to 5 additional cabinets - each can hold up to 400 discs (equalling 120TB) - which can be added to the side of the base unit, making the whole jukebox look like an 'L'. Total capacity would be more than 600TB with a maximum slot number of 2,200."

"We assume that such a unit will be available in second quarter this year."

Apparently additional expansion cabinets could be added but that has not yet been tested.

InPhase signed a similar OEM deal with ASM, another optical jukebox company, based in Westerstede, north Germany, in April 2006. Coincidentally DSM is also based in Westerstede.

However, ASM is insolvent and under chapter 11. It is not known if the company will survive.

The InPhase Tapestry disk holds ten times more data than Plasmon's 30GB UDO 1 disk. Plasmon has offered some criticism of holographic storage technology and likely products here.
