FCoE and VMotion – the Perfect Relationship

Just read the following article published by Mario Apicella from Infoworld. Mario’s article espouses the value of FCoE in providing storage connectivity ubiquitously to a host. When coupled with an application such as VMotion that demands perfect state synchronization not having to move a huge runtime image speeds the move. Having all of the servers connected to a common infrastructures overcomes the addressing and segmented connectivity challenges imposed by a SAN island architecture.Mario- appreciate your testing, and validation that what we have here is a technology that is not only easy to use and real, but is also adding value to virtualization and VMotion.dg

Green as a Journey not a Destination

Whether you call it eating your own dog food or drinking your own Champagne, we at Cisco are lucky to have very dynamic IT and facilities teams that trial our solutions as we develop them. Going Green is no exception. We recently kicked of our project within Cisco data centers and labs to benchmark our operative efficiency in order to make practical, targeted reductions in support of a public commitment to cut our Green House Gas (GHG) emissions by 25% from 2007 levels through 2012. By any measure this is aggressive in that it is an absolute reduction with no fine print…That means owned and leased properties as well as employee travel. Our rough breakdown of emissions is as follows: 1) Labs and Data Centers = ~60% 2) Employee Travel = 27% 3) Other; including refrigerants, propane, diesel for gen-sets, etc.You will notice we have an ~ sign for labs and data centers. This is because without specific instrumentation (sub-metering, branch circuit monitoring and IP-enabled power rails) there is only so much you can tell about where your power is going. You know even less about how efficiently you are using said power. The first level of analysis we can do using The Green Gird’s Power Usage Effectiveness (PUE) metric.So how are we framing this project that allows IT and Facilities to take better control of power consumption, capacity and growth? It is more simple than you might think. If you’ve worked with a spanning tree configuration, this is a breeze! We’ve basically broken this out into “digestible” phases that build upon each other. We’re lucky to have partnerships in some key areas to help us through it and a programmatic methodology through our Efficiency Assurance Program (EAP). Basically here is how we are approaching it today: 1) Establish electrical efficiency benchmarks for a pilot site including IT asset and system utilization (i.e. what is our server CPU utilization, some figures suggest the US average is ~20%) 2) Assign a balanced scoring to the pilot site that balances efficiency with risk and cost 3) Asses the IT and facilities architecture(s) to identify and prioritize improvements to net capacity, efficiency expressed as a percentage and growth projections 4) Develop new Standard Operating Environment (SOE) guidelines at the room, row and rack level 5) Develop new Standard Operating Procedures (SOP’s) focusing on operative efficiency like regular IT asset utilization audits 6) Document it all in one place with the ability for users to easily make changes on the fly but governed by committee (Change Advisory Board as an example) 7) Assess the viability to scale the pilot across Cisco’s 52 data centers world wide (most of those are development data centers, lab/DC hybrids)What is clear up front is that there is no silver bullet for Green. Rather we are focused on taking a blended approach towards efficiency with all leading not bleeding edge technologies on the table. Virtualization is of course a front runner but we recognize that it has a big impact on our facilities as well. Improved collaboration experience to reduce employee travel like Telepresence is a great technology but if we didn’t address human travel habits through our booking systems we might be traveling just as much and using Telepresence on top of that. The list goes on but suffice to say, this is one of those areas where the often overused term of “holistic” really does apply. I talk a bit more about this on our upcoming Techwise TV event, airing August 21st. If interested you can register at www.cisco.com/go/efficiencySo how did we even get to this point? Over the last 18 months we’ve developed cross functional teams made up of what were in many cases people who had a personal interest in making their company a deeper shade of Green (one of those people happens to be our CEO). Lucky for us these folks also have strong business acumen and we’ve been able to sell the business case for doing this internally. This is where our Green Data Center Model Calculator was born from also found in the EAP.We will be making sure to share our progress within Cisco IT on how our Green journey is progressing. Drop us a note with any insight you might have to how this is ramping up at your company (even the political organizational stuff which we all know happens).Thanks for reading.

The Google Service Oriented Virtualized Cloud as a Service

This post is really a test of title/hype versus content. My personal bet is that because of this title coagulating every term that is riding the hype cycle at warp speed it will become my most clicked through post yet. Anyone taking that bet?As for some useful content- here are a few of our more commented posts or other things I liked that I saw recently…Virtualization 2.0 -- Data Center KnowledgeMy Thoughts on Where Cloud Computing May GoI also liked James and Sam’s discourse on What is a Cloud? Anyhow, I’ll post back up in a couple weeks and see if my guess is right….dg

More Like “The Color of Money”

In a recent post, Chris Mellor articulates what the impact of FCoE might be on the storage world. How storage switch manufacturers will have to retool their switches to support converged architectures and operating systems. How HBA vendors will have to now create a value proposition competing against entrenched Ethernet NIC vendors and especially how storage vendors will have to add native FCoE capability to their arrays and drives. And of course all this could have an impact to how iSCSI performs in the market as well.While I do agree with most of this assessment, I don’t agree with his conclusion. The fact is whenever there has been a battle between Ethernet and another network transport protocol, Ethernet has always won. Why should this time be any different? Fibre Channel is an excellent storage transport protocol but it is not ideal for a generalized transport of multiple data types. Ethernet has been doing this for some time and transporting storage will be the same as for any other upper layer application. Of course, Ethernet will have to evolve as it always has and Data Center Ethernet will offer the lossless and guaranteed delivery that Fibre Channel has today.Of course vendors like Cisco and QLogic are embracing FCoE as it delivers what customers have been asking for, a common transport for all of their of data. They realize that the data center is being virtualized and servers, storage, and networks have to work together to tackle the challenges that are in front of them.But these aren’t the only ones that see the opportunity of re-architecting the data center to support a virtualized infrastructure. Intel, Emulex, NetApp, and EMC are also supporting this effort as it allows them all to reach a much larger customer base than before.As our CEO likes to say, there’s an inflection point happening in the data center and those who are in front of it and ready to capitalize on it will definitely see “The Color of Money.”

We Have a Winner

So Brian Cantor won my little uptime contest. Brian dug up a C5K that has been up for over 3,450 days. Brian says

“I work for an insurance company and this particular switch serves as an access switch in one of our call centers. It has mostly end users but there are some printers and a couple of servers. As far as I can tell, this switch has been chugging away since before the new millennium.”

Congrats Brian--fleece en route.Omar
