the Alpha using different block sizes, but that may be do to lack of
I don't know if there was a difference in the blue enclosures vs the
green enclosures or not.
I do think that some of the external StorageWorks enclosures used High
Voltage Differential to allow enclosures to be greater distances from
the chassis they were connected to. - I think there was an interposer
board to translate from High Voltage Differential (HVD) and Low Voltage
Differential (LVD) which the drives used.
My exposure to DEC Alpha equipment was minimal and a LONG time ago. So
take everything with a grain of salt. But do be mindful that DEC liked
to mix and match things.
