Access "Tape bulks up to keep pace with disk"

Published: 19 Oct 2012

Is the amount of data a tape can store more important than how fast it can write it? Judging by some of the new drives hitting the market, tape vendors seem to think so. From one generation to the next, tape platforms are routinely doubling in capacity, while their performance is increasing at a much lower rate. For example, Quantum's new DLT-V4, the successor to DLT VS160, has twice its predecessor's capacity at 160GB native, but has only increased its native throughput by 25%--from 8MB/sec to 10MB/sec. Similarly, Quantum's roadmap for the next generation of Super DLT drives, the DLT-S4, will see capacity swell by 166% to 800GB, while performance increases by only 67% to 60MB/sec. The ability to hold more data is particularly important for tape drives that ship with entry-level servers, says Mark O'Malley, Quantum's product marketing manager. That's because today, most entry-level servers can ship with several hundred gigabytes of internal disk drives. Furthermore, Quantum's market research shows that low-end server buyers have very little in the way of ... Access >>>

Features
    • The lowdown on replication appliances

      Operating system- and storage array-agnostic, replication appliances give companies increased flexibility to address one-time and continuous data replication needs, while allowing applications to continue processing without data loss or to recover with minimal downtime.

    • Backup outsourcers think small

    • Storage salaries increase

      The results for Storage's annual salary survey are in and storage professionals report salary growth. While the increases over last year are modest, they do represent the third straight year that our exclusive survey has shown an increase in storage salaries.

    • File Systems: The state of the art by Brad O'Neill

      Generally overlooked, file systems are assuming a prominent place at the heart of new technologies that address some of the most vexing storage problems, such as scaling and performance. New file-system approaches provide the underpinnings for technologies such as clustering, global namespaces and wide-area computing.

    • Quality Awards: What are the best midrange arrays?

      Midrange array users are a generally satisfied group, according to the latest Diogenes Labs-Storage magazine Quality Awards survey. While all midrange array vendors fared quite well in this third installment of our awards program, the vendor that snared top honors might surprise some people.

    • Secure your backups

      The headlines tell the story: Lost tapes can jeopardize the confidentiality of personal information and cause public-relations woes for those companies charged with safeguarding that data. Encryption can solve the problem, but implementing tape encryption isn't so easy, as performance issues could impact backup windows.
