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.
