High Performance Storage System

HPSS Logo
Incremental Scalability
Based on storage needs and deployment schedules, HPSS scales incrementally by adding computer, network and storage resources. A single HPSS namespace can scale from petabytes of data to exabytes of data, from millions of files to billions of files, and from a few file-creates per second to thousands of file-creates per second.
About HPSS   :    The value of tape

Value of Tape

Hard Disk Drive (HDD) are an economical storage technology for high-capacity, lower-latency, random access to individual files and objects. NAND or solid-state disks (SSD) are economical storage technologies for high-bandwidth, high-IOPS, and low-latency storage requirements. Several TCO studies exist from various sources, but all agree, tape remains the most economical long-term higher-latency storage media and tape should remain the leader for years to come.

"Continuing the Search for the Right Mix of Long-Term Storage Infrastructure – A TCO Analysis of Disk and Tape Solutions”; David Reine and Mike Kahn; Report #TCG201; July 15, 2015. http://www.clipper.com/research/TCG2015006.pdf

In recent years, SSD slowed to 20% annual decreases in $/GB and in 2017 no decrease in $/GB because of the supply-demand imbalance. HDD slowed from regular 40% decreases in $/GB to 20% annual decreases in $/GB after a supply-chain problem in 2011. Tape saw 25% annual decreases in $/GB until 2014, where the annual decreases slowed to 10% in $/GB. This simply means the cost of storage is not dropping as fast as the data growth rate sighted in this RFI.

An IBM study comparing options for long term storage suggests that the uncompressed tape storage costs are about $16/TB, WAN distributed HDD storage costs about $200/TB, and cold public cloud storage options ranges between $130/TB and $250/TB at almost all scales from 10 PB to 100 PB to 1 EB.

Future Capacity of tape

In 2017, IBM research and Sony Corporation demonstrated tape technology allowing for cartridge capacity to reach 330 terabytes. Thus, one expects IBM to sustain the current enterprise and LTO roadmaps that it continues to promote.

Today, cartridges max-out at 15 TB native, future cartridges will hold hundreds of terabytes.

Tape Drive Vendors

In 2017, IBM became the sole tape drive manufacturer of LTO and enterprise tape technologies. HPSS software supports both LTO and enterprise tape, including the newest IBM LTO drives, the newest IBM enterprise drives, and the last generation of Oracle enterprise drives.

Tape Media Vendors

There are two tape cartridge manufacturers. Sony is the only authorized manufacturer of LTO tape. Likewise, Fuji is the only authorized manufacturer of IBM enterprise tape.

Modern Serpentine Tape

Modern tape drives write data to tape on consecutive wraps, in opposite directions, from one end of the media to the other, over-and-over until all of the wraps in each data band are filled with data.
