Research Storage Systems
There are multiple research storage systems in use at Indiana University. The Scholarly Data Archive and Research File System are administered by the Research Storage group. The Data Capacitor II and DC-WAN are administered by the High Performance File Systems group.
The Scholarly Data Archive (SDA) is primarily a tape based archive storage system. Currently SDA has a raw tape capacity of 5.7PB. It does have over 200TB of spinning disk that operates as a cache for files moving to or from tape. SDA is geographically distributed between the IUPUI and IUB campuses. By default, a file stored in SDA will have a copy on each campus. This protects from minor problems like tape failures to major ones like a site disaster. Each campus has an automated tape library capable of holding over 5,000 tapes and 24 high speed tape drives. SDA has an aggregate transfer rate of over 2GB per second. It is capable of storing files from about 1MB to over 5TB is size.
The Research File System (RFS) is a spinning disk system with currently 30TB of total capacity. RFS can be mounted on the desktop or accessed over the web or SFTP protocol. RFS supports active editing of files and documents unlike the SDA. Files are backed up on a nightly basis from RFS. RFS has robust support for project work as well. Quota's start at 10GB for personal space and 50GB for project space.
The Data Capacitor II (DC2) is a high speed/high bandwidth storage system for research computing that serves all IU campuses and other sites throughtout the country. At peak performance, the Data Capacitor has a 40 gigabit per second aggregate transfer rate.
IU is first in implementing a geographically distributed HPSS in production and is one of the largest HPSS sites in the world. IU is also a national leader among academic institutions in high-end storage R&D.
Distributed storage at IU supports the efforts of the Indiana Genomics Initiative (INGEN) and has received financial assistance via INGEN. The Indiana Genomics Initiative (INGEN) is supported in part by Lilly Endowment, Inc. DS @ IU is also supported in part by Shared University Research grants from IBM, Inc. to Indiana University. Financial assistance is also acknowledged by the National Science Foundation to Indiana under Grant No. 0116050.
