The Magstar(TM) MP (Multi-purpose) 3575 Tape Library Dataserver has been enhanced with the addition of a patented new Multi-Path architecture, supporting sharing by homogeneous and heterogeneous hosts. The 3575 supports up to six SCSI-attach systems, in up to three logical libraries, sharing a common tape cartridge inventory and robotics. Support for Magstar MP Model C tape drives, with increased aggregate data rates (up to 15 MB/second using maximum data compression), and the ability to configure 14 bulk I/O slots within the library, in addition to the 2-cartridge I/O slot, are part of the Multi-Path feature.
The 3575 Tape Library provides a mid-range and network server tape storage solution combining reliable, field-proven, automated tape handling and storage with reliable, high-performance Magstar MP tape drives. Customers can tailor the library to match their system capacity and performance needs from 420 GB to 2.26 TB (1.26 TB to 6.8 TB with 3:1 compression) with Fast Access Linear Tape C-Format XL Data Cartridge, using up to six Magstar MP tape drives. Aggregate sustained data rates of 108 GB to 324 GB/hour with maximum compression allow extremely high data transfer performance. The 3575 offers outstanding retrieval performance with typical cartridge move times of less than four seconds. Native device driver support is included for AS/400, RS/6000(TM), and other popular SCSI-attach open systems from manufacturers such as Hewlett-Packard** (HP), Sun**, and Microsoft Windows.
Model Abstract 3575-L12 The IBM 3575 Model L12 offers customers up to 840 GB of uncompressed data storage with their choice of up to four Magstar MP Model C tape drives. The library has 120 cartridge slots and, with feature 1400, includes two Magstar MP Model C tape drives. Using Fast Access Linear Tape C-Format XL Data Cartridge, data capacity is 840 GB in native mode, 2.52 TB with Lempel-Ziv (3:1) compression. Using C-format Tape Cartridges in Magstar MP Model C tape drives results in an aggregate sustained data rate of 108 GB to 216 GB/hour with maximum compression.

Description Designed for Automated Tape Handling. The IBM Magstar MP 3575 Tape Library is a new family of tape library storage solutions designed for the large, unattended storage requirements of today's mid-range systems and network servers. Each aspect of the subsystem is designed to optimize access to data and reliability. Magstar MP tape drives are compact storage devices that support the highly intensive read and write operations required by today's network server systems. The Magstar MP Fast Access Linear Tape Cartridge utilizes an innovative new mid-point load design providing faster access to data than traditional tape cartridges.
High Performance Cartridge move time within the IBM Magstar MP 3575 Tape Library is typically less than 4 seconds. A dual-gripper picker can retrieve the next cartridge to be mounted, unload the current cartridge, and load the next cartridge, providing the following benefits: Saves complete move operations Further improves overall library performance Offers increased redundancy and higher reliability.
The average drive search time to first byte of data is eight seconds. Sustained data rates using Magstar MP Model C tape drives and C-format cartridges during reads and writes are 15 MB/second using maximum compression and 7 MB/second in native mode. The Magstar MP Model C tape drives are designed for high performance in both streaming and start/stop modes of operation. Automatic data caching, using an expanded cache memory and read/write buffering, enhances performance even further. Increased tape speeds, double the read/write heads, and a new (patent pending) digital data flow circuit take performance to new levels. Aggregate sustained data rates for the library are 108 GB to 324 GB/hour with maximum compression. Users with B-format data cartridges can realize significant performance improvements over 3570 Model B1A drives. Aggregate sustained data rates of 75 GB/hour up to 226 GB/hour, with 3:1 compression on B-format media, assure maximum utilization of existing library data.
High Reliability Leading-edge technology from IBM positions the Magstar MP tape drives as industry leaders. Highly accurate recording is provided by an exclusive thin-film write module designed by IBM with read after write data verification. Data read is managed by IBM's industry-leading magneto-resistive (MR) heads, designed for accuracy, high reliability, and durability. High-availability redundant servo readers also ensure consistent data integrity. Picker design in the library has been extensively field-proven in repeated cartridge handling operations. The IBM Magstar MP 3575 Tape Library is designed to minimize the amount of travel for robotic pickers within the library and improve performance. Drive cleaning is an automatic function performed by the library when required by the drive, without requiring operator intervention.
High Granularity in Library Configurations Features and capacities are designed to match the wide variety of customer requirements. The IBM Magstar MP 3575 Tape Library, with the Multi-Path feature, allows Magstar MP Model C and 3570 Model B1A drives to be intermixed within the library, but only if separated by logical libraries.
L06 Customers with moderate library needs can choose the Model L06. The library has 60 cartridge slots, and support for up to two Magstar MP Model C tape drives (refer to Note above). Using Fast Access Linear Tape C-Format XL Data Cartridges, data capacity is 420 GB of data in native mode, 1.26 TB using Lempel-Ziv (3:1) compression. The aggregate sustained data rate is 108 GB/hour with maximum compression using C-Format Tape Cartridges and Magstar MP Model C tape drives.
