Product Description
IBM 3573-8147 LTO-4 Ultrium Half High SAS Tape Drive for TS3100/TS3200
The IBM 3573-8147 is an internal half-high LTO Ultrium 4 tape drive sled with a 6 Gbps SAS interface. Designed as a replacement or upgrade module for the TS3100 (3573-L2U) and TS3200 (3573-L4U) tape libraries, it enables higher drive density and dependable performance for automated backup, long-term archiving, and data protection using LTO-4 media in enterprise tape environments.
Key Features
- Half-High (HH) form factor optimized for library sled installation (supports up to 2 in TS3100 or 4 in TS3200).
- 6 Gbps SAS interface for high throughput and reliable connectivity within the library.
- Native 800 GB capacity per LTO-4 cartridge (up to 1.6 TB compressed at 2:1).
- Data transfer rate up to 120 MB/s native.
- Backward read/write compatibility with LTO-3 media; read compatibility with LTO-2.
- Supports application-managed encryption and WORM media for secure, compliant archiving.
- Integrated sled/caddy for straightforward insertion into compatible IBM tape library chassis.

This half-high drive maximizes drive density in the TS3100 and TS3200 libraries, allowing more concurrent operations and improved backup throughput while maintaining solid LTO-4 capacity. The 6 Gbps SAS interface delivers efficient performance in SAS-attached configurations, and backward compatibility preserves access to existing LTO-3 and LTO-2 media. It supports encrypted and WORM-based archiving for compliance, making it a practical, reliable choice for cost-effective, high-density tape automation in Power Systems and open systems environments.
Compatibility
The IBM 3573-8147 LTO-4 HH SAS tape drive is engineered for direct installation in IBM TS3100 (3573-L2U) and TS3200 (3573-L4U) tape libraries as a half-high drive sled (up to 2 HH in TS3100; up to 4 HH in TS3200). It connects via the library's internal SAS backbone and supports host connectivity through the library's external SAS ports to IBM Power Systems, open systems servers, or compatible SAS HBAs/adapters. Compatible with LTO-4 Ultrium cartridges and standard backup software supporting IBM LTO drives (e.g., IBM Spectrum Protect, Arcserve Backup, CommVault, Veritas NetBackup). Backward compatibility includes read/write on LTO-3 and read on LTO-2 for legacy data access. Supports AIX, IBM i, Linux, and Windows environments with appropriate drivers and adapters.
