What is... a PetaSite?

PetaSite is the brand name of a tape library system manufactured by Sony Electronics. Designed for digital content management, data backup and enterprise data storage applications, Sony's system is based on SAIT drive technology, currently the industry's highest capacity data tape technology.


The SAIT PetaSite system offers an automated tape storage density of up to 250 terabytes (TB) of native capacity per square meter of floor space, and a total native capacity of up to 1.2 petabytes (PB).

Sony's SAIT PetaSite systems offer an automated tape storage density of up to 250 terabytes (TB) of native capacity per square meter of floor space, and a total native capacity of up to 1.2 petabytes (PB). Sustained native data transfer rates for the SAIT PetaSite library reaches up to 2.88 gigabytes (GB) per second, and a standard file can be restored in just over one minute.

A basic SAIT PetaSite system contains two SAIT-1 drives, an Ethernet hub, a terminal server, and a PetaSite control unit. This entry system, encapsulated within a standard 19-inch rack console, is scalable to house up to 12 drives and 216 cartridges for up to 108 TB of native capacity in a flexible and highly available configuration. Up to seven cartridge and/or drive consoles can be added to the base system.

The cartridge consoles will allow users to add up to 330 cartridges for 165 TB of extra native capacity, and the drive/cartridge consoles will house up to 12 additional drives and 258 additional cartridges, totaling nearly 135 TB of extra native capacity.

Since data management software is critical to support data warehouses that are seeing double-digit growth each year, Sony delivers the SAIT PetaSite tape library pre-configured with its PetaServe hierarchical storage management (HSM) and PetaBack high-speed backup software applications.

PetaServe software is designed to achieve maximum storage performance by automatically transferring data from hard disk to tape to achieve a cost-effective storage balance. This enables administrators to efficiently manage file migration through policies, while the data movement remains transparent to the end-user who is retrieving the files.

PetaBack software provides quick, automatic backup of files to the SAIT PetaSite system's drives, with high-speed restoration of data to the host computer's hard drive.
