It seems this same question is posted on a different website, without any answer, We did not have any luck either from our internal resources, on the EMC Flex 8-16 Switch, also the drive link has been removed from the Dell website as well.
Is it displayed in the Device manager of the Host machine?
I have posted the question to ServerFault too in the hope of increased exposure to the question.
It appears in a system inventory log, very possibly taken from a Dell quote or delivery note.
Using Dell's website with the associated service tag, I can only uncover "EMC Flex 8-16" as a description...
