For our part, we have just posted a new white paper on FCoE Initialization Protocol, which was defined as part of FC-BB-5. FCoE Initialization Protocol supports many of the same functions as FIP in the Fibre Channel world (Fabric LOGIn, Fabric DISCovery, Exchange Link Parameters) in order to establish and maintain the virtual link between an FCoE End Node and an FCoE Forwarder (FCF) such as the Cisco Nexus 5000 that defines the edge of the fibre channel fabric. Amongst other things, that lets us build more sophisticated network topologies as we deploy an FCoE based unified fabric. Up to this point, End Nodes have had to be directly attached to the FCF; however, with FIP, you can have intermediate “passthrough” switches between the End Node and the FCF (as long as they meet certain criteria, laid out in the white paper). A quick example of where this might be helpful is a blade server chassis, where you might not want the cost and/or complexity of a full FCF in the chassis, but do want a switch that can serve as an FCoE passthrough to properly forward the FCoE traffic to an FCF.
Finally, its nice to hear from customers on the topic. To that end, Derek Masseth, Senior Director for Infrastructure Services at the University of Arizona, will be joining us on a webcast tomorrow to discuss his experiences with deploying unified fabric in his environment. The balance of the webcast will give you an update on some other goings on with storage as well as some new products on the horizon.
The Webcast is tomorrow, Tuesday, September 29, 2009, 10:00-11:00 a.m. PDT. It can be accessed at http://tools.cisco.com/cmn/jsp/index.jsp?id=90342 (no registration required, just go to the URL at 10:00 a.m. PDT and select “Play” to launch the live presentation).
Join us for a live Internet TV broadcast featuring our special guest Derek Masseth, Senior Director for Infrastructure Services at the University of Arizona, who will share his experience how the university united its data center using Fibre Channel over Ethernet (FCoE) to create a Unified Fabric.
With some recent upgrades to our Cisco MDS family of storage networking switches, I think its a good time to revisit strategies for protection against data loss, since it’s always a top of mind in any data center. While there are certainly a number of ways of preventing data loss, I think one of the coolest is EMC’s RecoverPoint solution. Moving beyond traditional approaches such as backups, snapshots or mirroring, RecoverPoint uses continuous data protection technology (CDP) to let you roll-back to any point in time.
One of the features I really like is the ability to create application-aware “bookmarks” for applications that are constantly generating I/O, so you can roll back to a point where the application is in a consistent state.
RecoverPoint takes advantage of a Cisco MDS feature called SANTap. Essentially, SANTap takes each write I/O and mirrors it to the connected RecoverPoint Appliance (RPA). Because this is done at the fabric level, is completely transparent to the host and because the splitting is done out-of-band, it does not impact availability and integrity of the host I/O or application performance.
In support of this solution, Cisco is introducing the MDS 18/4 Multiservice Module (18 x 4GB FC, 4 x GbE, next-gen service engine) and the MDS 9222i Multiservice Modular Switch (18 x 4GB FC, 4 x GbE, next-gen service engine, 1 expansion slot). Both platforms are fabric speed agnostic, so it does not matter if the host initiating I/O is 4GB attached, 8GB attached or FCoE attached.
For a good summary of the solution, check out this video featuring Paolo Pio from Cisco and Rick Walsworth from EMC:
One of my favorite stories is one attributed to Christopher Wren, the architect behind St Paul’s Cathedral. The short version of the story is that Wren was visiting the worksite for St. Paul’s Cathedral. He came across a bricklayer diligently working away and asked him what he was doing and he replied he was laying bricks. A little bit later, he came across a second bricklayer and asked him what he was doing, and he replied that he was making a living. Finally, he came across a third bricklayer and asked him what he was doing and replied, with a gleam in his eye, that we was building a great cathedral.
So, what does this have to do with data center? Well, I think our market has a lot of folks that are in bricklayer mode–they are happily simply supplying and laying bricks and quite proud of that–they don’t care what you build as long you build it with their bricks. Because of the increased attention and spend that data center is seeing, we are now seeing an influx of folks who are here to make a living. They might never have touched a brick before, but this is where the money is so this is where they are–maybe they will be here tomorrow and maybe not.
But if you look at IT companies today that are talking about building cathedrals–that have a fresh, defined vision and a blueprint behind it–the list is depressingly short. I can only think of a handful of companies that have an interesting and innovative view of the future and the ability to get there.
There is a lot of excitement these days with Cisco decision of being a Platinum sponsor of Oracle OpenWorld 2009 October 11–15, at the Moscone Center in San Francisco, California.
Cisco and Oracle have been for a long time partners and industry pioneers, bringing innovation to data center environments to improve productivity, increase service agility, and lower total cost of ownership.
So far Cisco Data Center Network solutions, including the Application Networking Services (ANS), have been delivering great platform for your Oracle infrastructure. With the launch of the Unified Computing Systems this year, actively supported by Oracle, Cisco is providing a new level of services and systems to the Oracle applications users and administrators , that we describe as Fast, Simple and Proven .
So if you plan to be at Oracle Open World 2009, we invite you to attend our speaking sessions and visit Cisco booth (#2301 ) to get the latest news from our experts about Oracle validations and benchmarking results. Here are some details of what you can expect
