The IBM 3570 Model B00 is a drive unit with 1 tape drive, 1 cartridge, a tape drive data rate of 2.2 MB/sec, and is a stand-alone unit.

The IBM Magstar MP is designed to meet the increasingly demanding needs of the mid-range marketplace. It was designed to be part of an automation offering that offers unsurpassed reliability in its class. It has the ability to provide traditional save/restore function in addition to leading edge applications that are high I/O intensive operations where multiuser (particularly read) access is required.

Model Summary Matrix

The IBM Magstar MP Tape Subsystem is a revolutionary new multipurpose (MP) tape subsystem designed for automation to attach to AS/400, and RS/6000 systems. It is based on the same reliable Magstar technology as the IBM 3590 High Performance Tape Subsystem. It is designed to provide midrange systems a tape subsystem that has high levels of reliability, with lower price, capacity and performance than the 3590. It also provides a faster data access than other tape technologies with a drive time to read/write data of 8 seconds from cartridge insertion.

The Magstar MP is a compact, integrated storage subsystem that functionally expands the capability of tape to perform both write and read intensive operations. The Magstar MP utilizes a unique new robust heavy usage Fast Access Linear Tape cartridge that is approximately half the size of IBM 3480/3490/3590 cartridge tapes and is designed for high reliability. The tape drive reads and writes data in a 128-track format, reading and writing four tracks at a time. Data is written using an interleaved serpentine longitudinal recording format starting at the center of the tape (mid-tape load point) and continuing to near the end of the tape. The head is indexed to the next set of four tracks and data is written back to the mid-tape load point. This process is continued in the other direction until the tape is full. The capacity is 5GB per cartridge (15GB with 3:1 Lempel-Ziv compression). The drive data transfer rate is 2.2 MB/sec (uncompacted) with a 20 MB/sec burst data rate. The sustained data rate with maximum compression is 14 MB/sec. The IBM Magstar MP brings a new dimension of functionality to tape storage because of its revolutionary data recall performance allowing new applications to be enabled in addition to traditional tape applications.

The Magstar MP Model B00 is a stand-alone drive. It contains an integrated microprocessor control unit and all necessary power and cooling components. It attaches to a host system through a SCSI-2 adapter. The integrated control unit contains the electronics and logic for reading and writing data. The control unit functions include management of the data buffer, error recovery procedures, and the control of all tape drive operations and some channel operations. The Model B00 tape drive contains a compact loading mechanism that handles the Magstar MP Fast Access Linear Tape cartridge. Operator and service communications and message interface is handled by a combination of three LED indicators.
