Is a Brocade DS-300B fibre switch capable of being upgraded to handle Ethernet?

Hello - we have EMC Brocade DS-300B switches that are in place for an EMC storage array, and we're wanting to use the extra open ports on the Brocade switch to allow fibre transmission speeds between a couple servers as well.  But we're told these are "basic switches" incapable of Ethernet over fibre.  We're looking for the experts to weigh in on this, and if this is correct, is there anything we can do to "upgrade" the switches to be able to do Ethernet over fibre?  If there is nothing we can do, what switch model is recommended to do what we're looking for?

Thanks very much!

You have been told correctly, these fibre channel switches were made well before convergent networking was even thought about.

If "couple" means two you can connect two servers together with 10Gb Ethernet without switches anyway.

Ahh - I didn't realize there is 10G Ethernet cards.  So if I put 10g cards in the 2 servers, to allow then to transmit data, would I need to go through a switch?

you're saying connect them directly together without a switch?

If there are only two servers and you want a dedicated high bandwidth path between them then yes, connect the two NICs together with a [cross-over*] cable on a separate subnet. Bear in mind limitations such as dual-homed master browsers in Windows but it's great for things like vMotion.

Depending on your NICs you don't need fiber or Ethernet cable, if you haven't bought them yet then 10Gb SFP+ NICs plus a SFP+ DAC cable should be cheapest. You can't use a fibre-channel DAC cable, has to be Ethernet 10GSFP+Cu, max length is about 7m.

*You don't actually order cross-over cables any more, 1Gb and 10Gb NICs have automatic cross-over if needed and SFP+ DAC cables and fibre cables are all cross-overs.
