Fibre Channel Notes

English: LC optical fiber connector.

We have an old 2GFC SAN storage array (EMC) and needed to buy an HBA to connect a new server. The HBA’s from our vendor were listed as 4GFC, so I had to check on backward compatibility. Thanks to wikipedia, I found this:

“Products based on the 1GFC, 2GFC, 4GFC, 8GFC and 16GFC standards should be interoperable and backward compatible.”

There were also cards listed as “SW” (short-wave) which seems to be a fibre-channel way of saying “multi-mode” and “short-range”. The long-wave cards support very long distances and use single-mode fiber.

A 4GFC SW card will meet our 2GFC multi-mode needs nicely :-). Now just need to check the vmware hardware compatibility list for driver support.

Keeping technology notes on to free up my mind to solve new problems rather than figuring out the same ones repeatedly :-).
