The IBM® TS4300 Tape Library is a high-density, highly scalable, easy-to-manage solution designed to keep data securely stored long-term, while helping reduce the costs associated with data center space and utilities. Its modular design enables you to increase cartridge and drive capacity as needed—scale vertically up to sixteen modules with expansion for Linear Tape-Open (LTO) Ultrium cartridges, drives and redundant power supplies.
The modular architecture facilitates scalability of both cartridge and drive capacities according to demand. This library, based on a compact 3U-high modular base, supports vertical expansion with up to sixteen modules, incorporating the base, Linear Tape-Open (LTO) Ultrium cartridges, drives, and redundant power supplies. A solitary robot efficiently manages operations across all modules within the stack. In a fully expanded setup, a TS4300 can accommodate up to 640 LTO cartridges.
Security Compliance Capabilities
Requirements for secure, long-term data retention especially in the financial services, healthcare and life sciences industries are common and increasingly stringent, with data volumes escalating exponentially. Data stored on offline tape or write-once media, is nearly impervious to hacking.
Base Library for Complete Management
The base library contains all the necessary robotics and intelligence to manage the base library system, with a maximum of 40 slots of LTO cartridge capacity per module, five input/output (I/O) slots, and support for three combinations of full- and/or half-height (FH or HH) LTO drives per module. The TS4300 base library is rack or tabletop mountable. Module expansions are only rack mountable.
Simplify Tape Storage Deployment and Management
The TS4300 is based on an embedded, open-source software architecture to help speed deployment and simplify management. Best-in-class error recovery and reporting, library health monitoring and alerting, and auto-recovery features help to speed diagnostics and resolution. An automation drive interface significantly increases drive communication speed for faster code updates and log downloads.
IBM offers diverse management software solutions for TS4300 to enhance the use of multipath architecture, as well as the use of a single TS4300 library. The library software includes application programming interface (API) hooks that enable easy integration of IBM software.
