PetaSite Scalable Library

Petasite libraries use the Sony Optical Disc Archive drives and cartridges.  The system starts with a Single 7U unit the ODS-L30M.

Expandable with up to 5 Extension Units

The ODS-L30M forms the basis of the PetaSite scalable library that is easily scalable with ODS-L60E (Drive and Cartridge) and ODS-L100E (Cartridge only) extension units. 

The ODS-L60E extends the PetaSite, scalable library operating longside the ODS-L30M and ODS-L100E (Cartridge only) expansion units, while the ODS-L100E extends the PetaSite, scalable library operating alongside the ODS-L30M and ODS-L60E (Drive and Cartridge) expansion units. 

Up to a maximum of five expansion units can attach to the ODS-L30M to make a single 42U library offering a maximum of 535 cartridges (2.9 PB), depending on the extension units used.
