Description
The IBM Magstar MP Tape Subsystem is a revolutionary new multi-purpose (MP) SCSI-attach tape technology designed for automation. Traditionally, tape has been used to perform write-intensive operations like backup and data interchange. The Magstar MP is truly a multi-purpose storage device that functionally expands the capability of tape to optimize both write- and read-intensive operations. It provides the characteristics of high save and recall performance with reliability.
High Performance:
The IBM Magstar MP is designed to provide fast access to data. The drive and cartridge are uniquely designed to allow fast cartridge insertion, almost instantaneous head/tape contact at load time, and mid- point load, where the tape is already positioned to achieve fast data access by quickly fast forwarding to data in either direction. The drive search time to first byte data is about 8 seconds. Using C-Format cartridges, the Magstar MP Model C drives have sustained data rates of 7 MB/sec native and 15 MB/sec with maximum compression. Using B-Format cartridges, the Magstar MP Model C drives have sustained data rates of 3.5MB/sec native and 10.5MB/sec with 3:1 compression. The drive burst data rate is 20 MB/sec. Automatic caching of data enables balancing system read/write performance. The drive is designed to provide high performance in both streaming and start/stop operations. A new digital data flow circuit and an increase in tape speed by 50% reduces read/write operation times. These characteristics are exciting new technical breakthroughs in an industry that has historically only seen innovation in the form of increased cartridge capacity and data rate.
High Reliability:
The IBM Magstar MP provides outstanding reliability backed by a 3-year warranty. In the area of reading and writing, IBM provides leading-edge technology. Data write is provided by an exclusive thin-film write module that is designed for extremely accurate recording. Data read is provided by IBM's leading magneto-resistive (MR) head based on IBM Magstar 3590 technology. The head is based on IBM advanced magneto- resistive recording technology that is designed for high reliability and performance. In addition, the 8-track head provides data redundancy and servo tracking to ensure superior data integrity in the mid-range tape marketplace. It offers technology that was previously affordable only in the large systems environment.
A New Cartridge:
IBM has been awarded numerous patents for the innovative new cartridge technology. The IBM Magstar MP features two tape spools with the tape load point positioned at the mid-point of the tape to provide fast access to data, while still providing unmatched capacity for backup needs. The Fast Access Linear Tape C-Format XL Data Cartridge has an uncompacted capacity of 7 GB (21 GB with 3:1 Lempel-Ziv compression). The previously announced Magstar MP Fast Access Linear Tape Cartridge has an uncompacted capacity of 5 GB (15 GB with 3:1 Lempel-Ziv compression) and contains major enhancements over conventional data recording cartridges. A rugged case, designed for repetitive handling by automated pickers, protects the tape in an enclosed environment. The cartridge contains advanced metal particle tape media developed for high capacity and durability. The tape never leaves the cartridge because the cartridge contains the tape path itself. The tape medium is protected from being harshly handled by external pickers, rollers, or external guides. The unique tape path eliminates tape thread time, reduces complexity, and enables higher reliability. The internal tape path also allows quick load time and, combined with the mid-point load, provides leading-edge tape performance.
Investment Protection
Customers with existing Model B libraries can use their B-Format cartridges in the new Model C drives and realize a 50% improvement in performance. Existing B-Format data can be read and updated by the new Model C drives. For B-Format cartridges, the Magstar MP drives have sustained data rates of 3.5MB/sec native and 10.5MB/sec with 3:1 compression.
The 3570 Library Subsystem:
The Magstar MP 3570 library models, C01, C02, C11, and C12, are designed specifically to exploit the fast performance and match the reliability of the Magstar MP drive. They have been extensively tested and tuned to handle the rigorous demands of automated tape handling. They offer both an Automatic (sequential) mode for traditional tape processing applications and a random mode for applications requiring direct access to data. The library is designed to operate with two 10-cartridge magazines providing from 140-420 GB (using Fast Access Linear Tape C-Format XL Data Cartridges) of data accessible to the host system. When a cleaner cartridge is available in the library, it can be automatically inserted into the drive for a cleaning operation with no operator intervention. The drive also provides a fast load/ready time, greatly reducing the time to get to data for tape applications. The IBM Magstar MP promises to bring 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 3570 library models C02 and C12 also offer users the ability to configure the library as two logical libraries. Each library has its own drive and cartridge magazine. The autochanger is shared among the two libraries. Each library also has its own SCSI bus and can be attached to separate homogeneous or heterogeneous systems.
