Tape Addresses New Markets as Capacity, Performance, and Functionality Reach New Levels

For the past decade, the tape industry has been re-architecting itself and the renaissance is well underway. Several new and important technologies for both LTO (Linear Tape Open) and enterprise tape products have yielded unprecedented cartridge capacity increases, much longer media life, improved bit error rates, and vastly superior economics compared to any previous tape o r disk technology. This progress has enabled tape to effectively address many new data intensive market opportunities in addition to its traditional role as a backup device such as archive, Big Data, compliance, entertainment and surveillance . Clearly disk technology has been advancing, but the progress in tape has been even greater over the past 10 years. Today’s modern tape technology is nothing like the tape of the past.

The Growth in Tape
Demand for tape is being fueled by unrelenting data growth, significant technological advancements, tape’s highly favorable economics, the growing requirements to maintain access to data “forever” emanating from regulatory, compliance or governance requirements, and the big data demand for large amounts of data to be analyzed and monetized in the future. The Digital Universe study suggests that the world’s information is doubling every two years and much of this data is most cost-effectively stored on tape.

Enterprise tape has reached an unprecedented 10 TB native capacity with data rates reaching 360 MB/sec. Enterprise tape libraries can scale beyond one Exabyte. Enterprise tape manufacturers IBM and Oracle StorageTek have signaled future cartridge capacities far beyond 10 TBs with no limitations in sight. Open systems users can now store more than 300 Blu-ray quality movies with the LTO - 6 2.5 TB cartridge. In the future, an LTO-10 cartridge will hold over 14,400 Blu-ray movies . Nearly 250 million LTO tape cartridges have been shipped since the format’s inception. This equals over 100,000 PB of data protected and retained using LTO Technology. The innovative active archive solution combining tape with low-cost NAS storage and LTFS is gaining momentum for open systems users.

    · Tape cartridge capacity (native) growth is on an unprecedented trajectory
    · Tape has a faster device data rate than disk
    · Tape has a much longer media life than any other digital storage medium
    · Tape’s functionality and ease of use is now greatly enhanced with LTFS
    · Tape requires significantly less energy consumption than any other digital storage technology
    · Tape storage has a much lower acquisition cost and TCO than disk

Reliability
Tape reliability levels have surpassed HDDs. Reliability levels for tape exceeds that of the most reliable disk drive s by one to three orders of magnitude . The BER (Bit Error Rate - bits read per hard error) for enterprise tape is rated at 1x1019 and 1x1017 for LTO tape. This compares to 1x1016 for the most reliable enterprise Fibre Channel disk drive.

Capacity and Data Rate
LTO - 6 cartridges provide 2.5 TB capacity and more than double the compressed capacity of the preceding LTO-5 drive with a 14% data rate performance boost to 160 MB/sec. Enterprise tape has reached 8.5 TB native capacity and 252 MB/sec on the Oracle StorageTek T10000D and 10 TB native capacity and 360 MB/sec on the IBM TS1150. Tape cartridge capacities are expected to grow at unprecedented rates for the foreseeable future.

Media Life
Manufacturers specifications indicate that enterprise and LTO tape media has a life span of 30 years or more while the average tape drive will be deployed 7 to 10 years before replacement. By comparison, the average disk drive is operational 3 to 5 years before replacement.

LTFS Changes Rules for Tape Access
Compared to previous proprietary solutions, LTFS is an open tape format that stores files in application - independent, self-describing fashion, enabling the simple interchange of content across multiple platforms and workflows. LTFS is also being deployed in several innovative “Tape as NAS” active archive solutions that combine the cost benefits of tape with the ease of use and fast access times of NAS. The SNIA LTFS Technical Working Group has been formed to broaden cross – industry collaboration and continued technical development of the LTFS specification.

TCO Studies
Tape’s widening cost advantage compared to other storage mediums makes it the most cost - effective technology for long - term data retention. The favorable economics (TCO, low energy consumption , reduced raised floor) and massive scalability have made tape the preferred medium for managing vast volumes of data. Several tape TCO studies are publicly available and the results consistently confirm a significant TCO advantage for tape compared to disk solutions.

According to the Brad Johns Consulting Group , a TCO study for an LTFS - based ‘Tape as NAS’ solution totaled $1.1M compared with $7.0M for a disk - based unified storage solution. This equates to a savings of over $5.9M over a 10 - year period, which is more than 84 percent less than the equivalent amount for a storage system built on a 4 TB hard disk drive unified storage system. From a slightly different perspective, this is a TCO savings of over $2,900/TB of data.
