Data Center Networks Discussion of Networking-Based Technologies Designed to Optimize Data Centers

Every cloud needs a net

Most enterprises have been exploring cloud computing to see how it might work for them.  Cloud computing offers the ability to run servers on the Internet on demand.  The storage, compute, and network functions are positioned and ready for use, so servers can be deployed within minutes, and paid for only for as long as they are in use.

An essential component of any cloud installation is its network.   When servers are deployed in a cloud, they need an external network to be usable.  The network services that they need are more than simple IP connectivity, and each customer of the cloud will need some customization.  Here are some key types of cloud network service.

Wishful Thinking: The Innovation Edition

I am an unabashed fan of social networking.  For the data center team, being able to get direct, unfiltered feedback from the market has been a boon for making sure we are tracking in the right direction.  I also thoroughly enjoy the online conversations on the various blogs and in Twitter.  There are a great number of people out there with a lot of good thinking on the data center and I highly encourage you to do a little googling to get plugged into these conversations.  There are folks out there with views diametrically opposed to mine (you know who you are) but they have well-reasoned, well-spoken opinions and you can’t help but respect them for that—and I honestly enjoy the back-and-forth.

And then I’ll come across something that will leave me scratching my head thinking “Really…that’s the best you could come up with?”  I was reminded about this when I recently ran across a diatribe on our “lack of innovation”.  So, as a company, I will readily admit that there are a number of things we need to work on (and are), but “lack of innovation”? Really?

Let’s deconstruct this a little bit.  Just for the sake of argument, let’s start with a definition.  My trusty Mac dictionary defines “innovate” as “make changes in something established, esp. by introducing new methods, ideas, or products,” so lets run with that.  So, what have we done along these lines in the data center space in the last 20 months or so (not meaning to brag, just trying to make a point):

Could the Converged Network Adapter be the most important element in a Unified Fabric?

Many vendors are touting the benefits of IEEE DCB, FCoE, CEE, DCE, Unified Fabrics, and many other marketing monikers for equipment consolidation.  Each component of the technology is interesting, but maybe no more so than the Converged Network Adapter itself.   Why so?  Let’s take a look.

Cisco Nexus 4001I Switch Module for IBM BladeCenter

On my previous blog post “What exactly is a Nexus 4000?” there were many questions/comments around OEM blade server vendors and details of Nexus 4000 Series Blade Switches . Today, IBM announced the details of the Cisco Nexus 4000 blade switch for their BladeCenter H and HT chassis.

Nexus 4001 Switch Module for IBM BladeCenter will provide the support for Fiber Channel over Ethernet (FCoE) and the emerging IEEE Data Center Bridging (DCB) standards over 10 GbE for IBM Blade servers.

So IBM becomes the first blade server vendor to make Cisco Nexus 4000 available for their blade servers. You can find the Nexus 4000 blade switch IBM description at:

Cisco UCS Gets the Nod From Oracle

So, we continue to see broad traction in the industry for the Cisco Unified Computing System.  The latest passenger on the UCS Bus is Oracle, which recently certified and validated the Cisco UCS platform for Oracle Enterprise Linux 5.3 and Oracle VM.  

As the picture illustrates, the test system was built around out UCS B-Series servers with EMC CLARiiON storage system with a mix of Fibre Channel drives and state- of-the-art Enterprise Flash Drives (EFDs) to further speed performance.  Its important to note that, because the Cisco UCS is architecturally consistent across form factors, the same system could be built with the recently announced C-Series rack servers.

We have published a white paper on the tested deployment that digs into a fair amount of detail on the setup and configuration of the system—highly encouraged reading for anyone that supports Oracle in an enterprise environment.  Please note, you will need to register to access the doc (any follow-up from us is on an opt-in basis).

One of the more interesting things  things that came out of the testing was the performance data. We ran the cluster through 24h hrs stress tests for both OLTP (order entry) and DSS (sales history). The results included:

• Very consistent CPU utilization: around 40 percent on all eight nodes
• No saturation levels of any subsystems (CPU, disk, I/O, or networking)
• Sustained FCoE-based I/O ranging between 1.8 and 2.0 GB per second, which could be further divided into 1.4 GB per second of Fibre Channel I/O and approximately 450 MB per second of interconnect communication
• No occurrence of I/O bottlenecks or wait times
• Excellent I/O service times for storage

We attribute much of this consistency to the UCS architecture and its intrinsic 10GB fabric as well as the use of the EMC CLARiiON storage with EFDs.  Note, this was not performance testing, there was no config optimization or the like done for this test, we were more interested in understanding how the system handled long-term sustained loads.  We are working on performance benchmarking, so stay tuned for those if you are looking for numbers to compare to other solutions out there.

The Internet Protocol Journal

One of the hidden gems at Cisco is the Internet Protocol Journal.   The IPJ describes itself as “... intended to serve as an informational and educational resource for engineering professionals involved in the design, development, and operation of public and private internets and intranets. It does not promote any specific products or services, but focuses on issues facing the network designer or operator. The journal carries tutorial articles (“What is…?”) as well as implementation/operation articles (“How to…”). It provides readers with technology and standardization updates for all levels of the protocol stack and serves as a forum for discussion of all aspects of internetworking.”

The quality of the content is quite good and a subscription is free.  One of the reasons I bring this up for our readers is the the current edition has a the first part of a two part primer by T. Sridhar on cloud computing.  For those of you looking to come up to speed, it is a good vendor-agnostic intro to the topic.

Of Cloud Computing and Virtualization

There still continues to be an immense amount of confusion around what exactly constitutes cloud computing.  As an example, over the last few days, there has been a spirited debate whether the Sidekick service Microsoft/Danger offered was a cloud-based service or not (I am not going to dig into that here, but I do happen to agree with Chris Hoff’s viewpoint).

A common question I get is if virtualization is an inherent and mandatory component of any cloud solution.  I bounced this question up to our CTO’s office to get their take on things.  Their perspective:

Cloud computing delivers IT resources on-demand and elastically, and many organizations would like to leverage these capabilities today. Compute virtualization established itself as a way to improve resource utilization, but has other characteristics that make it more broadly relevant to cloud.

To expound on this a bit further, Glenn Dasmalchi, technical chief of staff in the office of the CTO at Cisco, provides a summary of how cloud computing and virtualization are related, and what advantages are afforded to customers.    He also touches on the network play with the cloud-virtualization linkage.

Are You Getting Top Performance for Your Oracle Applications over the WAN?

With Oracle Openworld running this week it’s a good time to think about the performance of applications over the wide area network (WAN).  With the changing business environment IT organizations are re-architecting how they deploy enterprise applications. Oracle applications automate business processes and increase productivity, but in this new network-centric world their performance is being impacted by longer WAN links and inefficient Internet protocols resulting in reduced performance and decreased user productivity.

Globalization and outsourcing has created a workforce that is spread across the world. At the same time, to reduce IT costs resulting from the spread of regional systems, and to take advantage of large scale virtualized systems, organizations are centralizing their application and IT infrastructure in the data center. The result of this trend is that the distance from the end user to the application server has increased dramatically and the connection is often over links with limited bandwidth.

Taking Cisco UCS for a Test Drive

Thinking about test drives reminded me that my 12 year-old son will be driving soon (yikes!) which then got me thinking about other rites of passage he will soon encounter such as the roller-coaster experience of asking a girl out on a date for the first time and looking for that nod from her.  Which then got me thinking—-hmmm, that should get him ready if he ever ends up doing product marketing (twisted, I know).

You see, sending your product off to review is a lot like asking someone out—you embark with full confidence, but you still anxiously await the nod and smile. That’s how we felt when we gave eWeek’s Cameron Sturdevant free reign to poke, prod, test, and badger our new Cisco Unified Computing System B-Series blade server.  After four days of kicking the tires and looking under the hood at every nook and cranny, Cameron had a smile on his face.  (Whew…not that we were all that nervous, you understand…)  But Cameron, in his own words, is “impervious to hyperventilating marketing hype.”  (Not that we’d ever indulge in such language.)

You can read Cameron’s full review here as well as check a couple of slide show he put together of the hardware and the UCS Manager.

Cisco UCS News: New Servers and Making Waves in the Magic Quadrant

Well, boys and girls, I have got a couple of cool things to report on the Cisco Unified Computing System front.  First, and foremost, I am happy to present the latest iteration of the UCS: the C-Series rack servers.  

	The Cisco UCS C250 M1 server is a two-socket 2 rack unit (RU) rack-mount server with patented Cisco Extended Memory Technology designed to increase performance and capacity for demanding virtualization and large-data-set workloads
	The Cisco UCS C210 M1 server is a general-purpose, two-socket, 2RU rack-mount server. Housing up to 16 internal disk drives for up to 8 TB of storage, the UCS C210 M1 is designed to balance performance, density, and efficiency for workloads requiring economical, high-capacity, reliable, internal storage
	The Cisco UCS C200 M1 server is a two-socket, 1RU rack-mount server designed to balance simplicity, performance, and density for production-level virtualization, web infrastructure, and other mainstream data center workloads

You can follow each of the product links for details, but here is a quick snapshot of the differences between the models.  The C200 and C210 will be available in November and the C250 well be here in time to tuck under the Christmas tree of that special server geek on your Christmas list.

On the UCS traction front, Gartner has released their Blade Server Magic Quadrant.  While licensing restrictions preclude me from showing you the quadrant, I can discuss the results. Gartner has placed us in the Visionaries quadrant, which we believe is great place for us to debut.  Essentially, “Visionary” translates to recognition of our completeness of vision and questions about our ability to execute.  Since we are newcomers to this market, that is a fair assessment as we have to prove ourselves against the incumbent vendors.  As we continue to deliver product innovation and increase customer momentum, we expect that to change over time. Gartner believes that Cisco UCS technology is as good if not better than anything offered by the competition and recognized we posses the factors needed to drive continues success in this space including our innovation in created the UCS as a differentiated, integrated system, the strength of our partnerships and our global reach and existing footprint in most data centers.

Finally, Gartner noted that they see an uptick in the number of conversations that they are having around UCS—that there is a high level of market interest.  I was have having coffee with my old boss yesterday (he is now back in the field) and he mirrored this sentiment—every one of his customers—and these are large enterprise accounts—is interested in the UCS, regardless of what they already have in place.

Go Big or Go Home

I thought I would re-visit my cathedral-builders blog, since a couple of interesting stories popped up this week.

For starters, Nick Lippis posted a well thought out blog on his short list of cathedral-builders (Cisco, HP, and IBM).  Yes, I know I have a bias, but these three companies would be my top 3 as well.  I think all three companies have the correct blend of vision and completeness of footprint.  If I were to add a fourth, it would probably be either Oracle or Dell—both companies are certainly working hard on carving out a broader role.

Over at Gigaom.com, Gary Orenstein pondered if networking would become the final area of differentiation in the data center.  Certainly, I am not going to be upset if networking capability becomes the primary point of differentiation between Cisco, HP, and IBM , but, sadly, I don’t think it will be that simple.  I do, however, think he brings up an interesting dynamic for product vendors (the brick sellers in my original post).  If networking becomes a key point of differentiation, I don’t think the current arms-dealer approach of selling their wares to everyone and anyone will fly any longer.  If you are selling bricks with no compelling differentiation, then I think your business gets commoditized and the profit is driven out of it.  On the other hand, if you do have compelling differentiation, then I think you get get snapped up by one of the cathedral-builders to give them a point of differentiation in the broader data center battle that Gary talks about.

All, of which, perhaps helps explain the reports that surfaced this week that Brocade is shopping itself around.  This type of chatter usually makes customers nervous (often with good reason), but in the scheme of things, I can see why Brocade would want to take that risk and leverage its Fibre Channel expertise to find a home with one of the cathedral-builders in the market.

Anyway, I think it will be interesting to see what evolves over the next 12-18 months—how the cathedral builders flesh out their portfolio and what happens to the remaining brick sellers.
