Switches in SAN (Storage Area Networks) play a key role in maintaining the Frame forwarding to and fro between hosts and target. A general brocade switch consists of  condor ASIC and FPGA. SAS runs on the FPGA. SAS provides the intelligence to the brocade switches by means of virtualisation. During virtuailsation SAS provides the functionality to create virtual devices like volume of  capacity greater than the available back end storage and associated commands   to   do SCSI read and write related to such virtual devices. These virtual devices play a key role in mirroring, striping, online and offline data  migration.

Role Played: Worked as developer to extend the virtualisation for >2TB
