Tape Research
Overview
Magnetic tape data storage systems are experiencing a renaissance driven by the widespread utilization by hyperscale cloud companies. The increasing adoption of tape is driven by the convergence of two trends: 1) the continued exponential growth in data which averages about a 40% compound annual growth rate (CAGR) and 2) the recent slowdown in the areal density scaling of hard disk drives (HDDs). The net result: we are creating data at a much faster rate than we can afford to store it, at least if we want to store it all on spinning disk.
Fortunately, a large fraction of the world’s data, approximately 80%, is cold data, i.e. data that is infrequently accessed and hence can tolerate higher access latencies. For such applications, tape has multiple advantages:
- it provides a 4-8x lower total cost of ownership,
- it has up to a 96% lower CO2 footprint over its lifecycle,
- it provides additional security through a built-in air gap and
- tape has massive potential to continue scaling cartridge capacity for many future generations.
Research areas
- Developing the tape hardware and media technologies to enable the continued scaling of tape systems to cartridge capacities of hundreds of TB per cartridge and data rates of 1000MB/s and beyond.
- Modeling the performance and reliability of tape library systems.
- Developing software that makes tape easy to use and extremely reliable.
