Blessay: FCoE Is JUST a Transition Technology
December 17, 2009 by Greg Ferro · 9 Comments
Chris Evans believes that “FCoE” will rule the world. Hah. I believe it’s just a transition technology that drags Storage out of it’s closed, proprietary mindset into the open collaborative world. Data Networks can easily adapt.
FCoE Isn’t a Replacement for Infiniband, It’s a Cheaper Copy That Customers Will Buy

There is some misconception by many in the storage industry that FCoE is some type of replacement for Infiniband. My view is that FCoE is cheaper, dumber but MARKETABLE alternative.
Why Does iSCSI Use TCP Instead of IP ?

The iSCSI protocol carries block data from storage array to server. Typically, that is inside a data centre where loss is not a problem. So why use TCP and have all that overhead ?
DCB, CEE or DCE ? Whose Term Is Best ?

One of the most amusing parts about Fibre Channel over Ethernet(FCoE) is that Spanning Tree is making a triumphant comeback. And I am talking a Roman style parade after the gates to the city have been built and the streets lined with gold.
