HP StorageWorks Ultrium Full-Height Tape Drives

Compatibility

For the most up-to-date information about recommended SAS HBAs and supported cabling configurations with your make and model of server, always refer to http://www.hp.com/go/connect

Cables and Termination All cables required for a typical internal and external connection to HP servers are provided with your tape drive. For non-HP servers, please consult your manufacturers' server specifications to determine if the cable provided with your Ultrium tape drive is appropriate for use with that server. No terminator is required for internal models (assumes use of terminated cable). The external model features "auto- termination" – no terminator is required. New SAS-based Ultrium models ship with a 4-channel split cable which allows direct attach from embedded SAS controller on host to a tape drive and remaining 3 channels to disk.

NOTE: Visit http://www.hp.com/go/connect for the latest compatibility information.

Performance Tuning You will need to connect the drive to a dedicated SCSI Host Bus Adaptor (HBA) that is Ultra 160 HBA or higher. To supply data to the drive fast enough to achieve full performance from an HP Ultrium tape drive, you will need at least eight disks as part of a RAID 5 array with read cache enabled. You can test the speed of your system with tools provided at http://www.hp.com/support/pat or with HP's StorageWorks Library and Tape Tools application.

To achieve full performance from your tape drive, do not use the native backup application within the operating system (e.g., NT® Backup, Windows® 2000 Backup). For full details of supported backup applications, see http://www.hp.com/products1/storage/compatibility/tapebackup/index.html

LTO-4 1840 specifications

The HP LTO-4 1840 tape drive is a pivotal data storage solution shaped by the need for efficient, high-capacity tape storage. As part of the Linear Tape-Open (LTO) technology series, this tape drive was designed to cater to the growing demands of businesses for secure and reliable data backup, archiving, and recovery solutions.

One of the standout features of the HP LTO-4 1840 is its impressive storage capacity. Each cartridge can hold up to 800 GB of compressed data, which is ideal for enterprises needing to manage large quantities of information. When dealing with uncompressed data, the capacity is 400 GB, showcasing significant increases over previous generations. This advancement increases efficiency and reduces the frequency of tape changes, streamlining the backup process.

The LTO-4 technology also introduced a notable enhancement in transfer rates. The HP LTO-4 1840 boasts a native data transfer rate of 120 MB/s and up to 240 MB/s compressed. Such speeds provide businesses with faster backup and restore operations, minimizing downtime and enhancing productivity.

In terms of compatibility and flexibility, the HP LTO-4 1840 is backward compatible with LTO-3 and LTO-2 tape formats. This backward compatibility ensures that organizations can seamlessly transition to newer storage technologies while still utilizing their existing tapes, protecting their investment in legacy data storage systems.

Data durability is another hallmark characteristic of the HP LTO-4 1840. The tape drive employs advanced error correction and data integrity technologies, ensuring that stored data remains intact over long periods. Additionally, the drive utilizes a robust mechanism to reduce wear and tear on tapes, extending their longevity and reliability.

Security features are also embedded in the LTO-4 framework, including AES 256-bit encryption, which secures stored data and ensures compliance with various regulatory requirements. This encryption capability protects sensitive information from unauthorized access during the backup process.

The HP LTO-4 1840 tape drive is optimized for a range of environments, including small, medium, and large enterprises. With its combination of high capacity, fast transfer rates, robust security features, and compatibility with previous generations, this tape drive remains a reliable choice for organizations looking to safeguard their critical data assets effectively.
