Product Description
IBM 3573-8347 Ultrium 6 Half-High SAS Drive for TS3100/TS3200 Tape Library
The IBM 3573-8347 is an Ultrium 6 half-high SAS tape drive designed for the TS3100 Tape Library Express Model L2U. It delivers 2.5 TB native capacity (up to 6.25 TB compressed with 2.5:1 ratio) and up to 160 MB/sec native transfer rate, with hardware-based AES-256 encryption support when feature #5900 is enabled, making it ideal for secure backup, archival, disaster recovery, and compliance storage in AIX, IBM i, Linux, and VIOS environments.
Product Description
The IBM 3573-8347 Ultrium 6 Half-High SAS Drive is a field-installable drive for the TS3100 L2U / TS3200 L4U library (machine type 3573). It uses a 6 Gb/s SAS interface (dual-ported with two Mini-SAS connectors) and supports LTO Ultrium 6 media at 2.5 TB native capacity. With 2.5:1 compression, it achieves up to 6.25 TB per cartridge. The drive writes 16 data tracks simultaneously, includes a 512 MB internal buffer, and features digital speed matching from 40 to 160 MB/sec for optimal performance. It supports library-managed encryption (#5900 prerequisite) using AES-256, along with WORM media for regulatory compliance. The drive is read/write compatible with LTO-5 cartridges and read compatible with LTO-4. It fits in the TS3100 L2U library (up to two half-high drives or one full-high drive) and is designed for high-reliability operation with TMR head technology, dual-stage actuators, and advanced error correction. The 3573-8347 is perfect for enterprise backup and long-term archival in Power Systems environments attached via SAS HBAs.
