Blue Coat is updating hard disk drives (HDD) for all models of the Proxy SG300.
New 500GB HDDs will replace existing 250GB drives that are no longer manufactured.

The 500GB HDDs are fully supported and functionally equivalent to the previously used 250GB drives.
Blue Coat has thoroughly tested and approved the use of these HDDs for all Proxy SG300 models.

SG300s built with 500GB HDDs will commence shipping imminently.
Blue Coat will provide like-for-like RMAs for 3 months from the date of this announcement.
NOTE: Blue Coat will not be retroactively replacing existing HDDs.

Updated SGOS code it required to properly recognize the 500GB drives.

A Proxy SG300 with a 500GB HDD that is NOT running one of the supported SGOS versions, will display "unsupported configuration" in the SYSINFO:
