Storlite: Storage Systems Optical Networking
The Storlite project was a collaborative industry-academia research
project funded under the DTI/EPSRC LINK Information Storage and
Displays (LINK ISD) programme and led by Xyratex, a disk storage
company based in Havant. It has involved an investigation of the
application of affordable short-reach optical backplane technologies
to future architectures of storage systems. Xyratex has worked with
Exxelis (a company based in Glasgow) and University College London on
optical components and with ICSA at the University of Edinburgh (EPSRC
grant GR/S28143) on the simulation of RAID systems.
As the intra-enclosure transmission rate and the number of disks
required in each storage sub-system increase, implementing electrical
backplanes in storage systems is becoming increasingly
difficult. Hence, the optical part of the Storlite project
investigated how to implement optical backplanes for storage systems
to make them more scalable.
The simulation part of the project involved using HASE to create
simulation models of RAID storage systems and industry standard
benchmark traffic generators (SPC and IOmeter) and using these models
to identify performance bottlenecks, to evaluate communication
protocol options and to explore the design space for new hardware
acceleration architecture options for next generation storage
sub-systems based on optical backplanes.
Details of the results obtained can be found in the EPSRC Final Report.
