I worked with VL component which runs "initiator" of Spectrum Virtualize. Areas including discovery and management of node/drive/enclosure/third-party storage, IO path, multi-path, ERP, Timeout, SCSI, quorum disk management etc. SCSI is the interface to various devices, with this job I became an expert of SCSI commands/SBC/SPC, understood storage system and industry and also got familiar with hundreds popular storage systems/drive disks from market.
