"SDSC Announces Scalable, High-Performance Data Storage Cloud"
 Web-based System Offers High Durability, Security, and Speed
 for Diverse User Base

  "The San Diego Supercomputer Center (SDSC) at the University of
   California, San Diego, today announced the launch of what is
   believed to be the largest academic-based cloud storage system
   in the U.S., specifically designed for researchers, students,
   academics, and industry users who require stable, secure,
   and cost-effective storage and sharing of digital information,
   including extremely large data sets."

  "SDSC's new Web-based system is 100% disk-based and interconnected
   by high-speed 10 gigabit Ethernet switching technology, providing
   extremely fast read and write performance.  With an initial
   raw capacity of 5.5 petabytes - one petabyte equals one quadrillion
   bytes of storage capacity, or the equivalent about 250 billion pages
   of text - the SDSC Cloud has sustained read rates of 8 to 10 gigabytes
   (GB) per second that will continually improve as more nodes and
   storage are added. That's akin to reading all the contents of
   a 250GB laptop drive in less than 30 seconds."
  ""UC San Diego is one of the most data-centric universities in
   the country, so our goal was to develop a centralized, scalable data
   storage system designed to meet performance, functionality, and
   capacity needs of our researchers and partners across the country,
   and to evolve and scale with the needs of the scientific community,"
   said Dallas Thornton, SDSC's division director of
   cyberinfrastructure services. "Developing this resource in-house
   atop the OpenStack platform allows for highly-capable and flexible,
   yet extremely cost-effective solutions for our researchers.""


Durability and Security
  "The SDSC Cloud leverages the infrastructure designed for
   a high-performance parallel file system by using two Arista Networks
   7508 switches, providing 768 total 10 gigabit (Gb) Ethernet ports
   for more than 10Tbit/s of non-blocking, IP-based connectivity.
   The switches are configured using multi-chassis link aggregation
   (MLAG) for both performance and failover."
