HP Ultrium 1840i LTO4 Tape Drive

Setting new standards for capacity, performance and security, the HP StorageWorks Ultrium 1840 Tape Drive can store up to 1.6TB per cartridge while providing hardware-based data encryption to enable greater levels of security and unprecedented performance.

Overview

 

Overview

HP StorageWorks LTO-4 Ultrium 1840 Tape Drive represents HP’s fourth-generation of LTO tape drive technology positioned as HP’s first tape drive capable of storing up to 1.6 TB per cartridge while providing hardware-based encryption to enable greater levels of security and unprecedented performance.

Data hardware encryption using AES 256-bit provides easy-to-enable security to protect the most sensitive data and prevent unauthorized access of tape cartridges. By using LTO-4 Ultrium 1840 encryption, not only is data fully capable of being compressed therefore maximizing capacity, encrypted backups are completed without a loss in performance.

Capable of data transfer rates up to 240 MB/sec, HP’s exclusive Data Rate Matching feature further optimizes performance by matching host system speed to keep drives streaming and enabling the fastest tape performance in the industry.

The Ultrium 1840 provides investment protection with full read and write support with LTO-3 media, and the ability to read LTO-2 cartridge. By doubling the capacity of previous generation Ultrium drives, HP customers now require fewer data cartridges to meet their storage needs, significantly reducing IT costs and increasing ROI.

Support for Write-Once, Read-Many (WORM) media allows customers to implement a cost-effective solution to secure, manage, and archive data to meet stringent compliance regulations.

The LTO-4 Ultrium 1840 Tape Drive provides both U320 SCSI and 3Gbps SAS interfaces and supports the industry’s most comprehensive list of compatible hardware and software platforms.

Each drive option includes HP Data Protector Express Software Single Server Edition backup/recovery software and the HP Data Protector Express Software Bare Metal Disaster Recovery option, as well as support for HP One-Button Disaster Recovery (OBDR) and HP StorageWorks Library and Tape Tools (L&TT).
