So a while back, Cisco, VMWare and EMC announced that they are forming a partnership to co-operatively sell and support products in a joint venture named Acadia. Selected engineers and sales grunts, USD$200 million bucks and “no large customer left untouched” door to door marketing campaign. Is there anything to it ?
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.
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.
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 ?
FibreChannel over Ethernet (FCoE) is coming to your data centre. The problem is that FCoE doesn’t work properly on ordinary ethernet switches. What do I mean by “properly” ? We need new standards to let it reach its potential but there are too many acronyms.
Buried in this article from the Register is aparagraph detailing Emulex Gen2 chip that does all storage virtualisation in a single chip. The FC boosters will be unhappy, they will have to compete.
A number of storage bloggers have been questioning the relevance of FCoE and why would you bother with it. Given the size of marketing budgets pushing FCoE and the reality distortion this generates, lets look at the case AGAINST FCoE.
TRILL is a key network technology for enabling Cloud Computing by allowing for better migrations of VM’s, and better utilisation of the network switching fabric and much improved stability of the Data Centre Server Fabric.
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.
I was thinking over the integration of an IT Engineering team to provide a cloud computing services. While discussing team responsibilities and operational “edges” I realised how divisive and dysfunctional FCoE will be to a team.
