Xcerta 256i: High-Capacity, High-Performance Tape Storage

Xcerta 256i IBM-Compatible 3590e Tape Drive

When you need reliability, speed and storage capacity... You need the Xcerta 256i 3590e tape drive.

Blinding Speed

Xcerta 256i 3590e tape drive incorporates leading-edge streaming and start/stop performance. Xcerta 256i more than quadruples the uncompacted data transfer rate of the 3490E up to a maximum of 14 MB/sec. The maximum instantaneous data rate is 40 MB/sec on a SCSI interface.

Massive Capacity

The Xcerta 256i's cartridges hold 20 GB (100 times more than 3480 cartridges). Pack in up to 60GB with LZ1 compression.

The Xcerta 256i's cartridge is the same physical size as a 3480 cartridge.

Save Money

High capacity means you need less equipment, fewer cartridges, and fewer tape mounts. High performance means you don't need as many drives to get the job done. Maintenance costs are also lower than those for helical and 3480/3490 drives.


The advanced Xcerta 256i 3590e tape drive gains up to a 100-fold increase in data integrity over the 3480. Xcerta 256i uses a bidirectional serpentine recording technique and a second-generation magnetoresistive head, pumping out 16 data tracks at a time. Improved Error Correction Code (ECC) and servo tracks written on tape help ensure data integrity. Xcerta 256i's diagnostics help you find problems, and tell you how to fix them.


With its optional 10-slot Auto Cartridge Loader (ACL), the Xcerta 256i 3590e Tape Subsystem stores up to 600 gigabytes of randomly accessible data. Each library magazine loads and unloads easily. The Xcerta 256i allows both unattended operation and a display that clearly shows the tape drive's status, error conditions and messages.

Wide Connectivity

The Xcerta 256i attaches to selected systems from HP, Sun, HP/Convex, CRAY, SGI, and Intel-based WinNT systems, as well as to IBM AS/400, RS/6000, and S/390 systems.


The Xcerta 256i does not require scheduled preventive maintenance.


The Xcerta 256i 3590e tape drive is available as a standalone rack model or in automated library solutions. It attaches via a SCSI interface to selected IBM and non-IBM midrange and open systems.
