One of the more amusing byproducts of the FCoE marketing push, is that Brocade has announced that they will producing FCoE switches for their customers. So, are you ready to buy a Brocade Ethernet switch ?
An article I wrote on concerns about FCoE adoption has been posted at The Future of Storage and reviews seven reasons why FCoE might not achieve critical mass in the marketplace. Feedback appreciated. Is anyone considering using FCoE in real life ?
In iSCSI Part 3 – Server Side – iSCSI Host Bus Adapters and IP Performance I looked at how server side issues would affect the traffic generated on a per server basis. I recommended that you use iSCSI HBAs for high intensity servers to meet the high levels of performance.
The next level is evaluate how the server should connect to the network, specifically, this means how many ethernet ports you need, and what configuration is needed to support them to deliver high availability / redundancy and increased bandwidth.
I am working my way through the next couple of articles on iSCSI Network Design. Its getting complicated is some ways. I noticed this article todayhttp://vinf.net/2008/04/09/how-does-an-hp-fibre-channel-virtual-connect-module-work/ explaining how Fibrechannel failover work for a HP Fibrechannel Virtual Connect in a blade server chassis. It is all rather confusing, and seemingly no more complex that the iSCSI network design.
Its possible that you would already have some Fibrechannel in your estate. Perhaps the cost of Fibrechannel for some new servers is too much when you calculate the HBA and Fibrechannel switch port costs, or you don’t need the complexity of Fibrechannel for a simple server setup. Lets look at options for connecting to the Fibrechannel nteworks.
