Our Evolving Stripes…

Today, as I sat in my office wondering what to do since I cannot play Scrabulous any more (and still try to get a 500 point game, hit 490 the other week….) I was reading about clouds. Not the cloudy kind of judgement that causes things like Scrabulous to be shut down, but the kind of clouds that are on the beginning of the superhighway of Hype- Cloud Computing! There was an interesting article on GigaOm today about Networking Vendors Must Change Their Stripes to address the opportunity provided by the cloud computing evolution that is beginning to happen in the market. The first thing about evolution is that these architectural evolutions do not happen nearly as fast as the authors of such articles would like to think, and definitely not as fast as it takes to write above-said article. But notwithstanding there is some real ‘meat’ behind the Cloud Movement. It is an EVOLUTION though- an evolution of servers, of storage, of the networks that interconnect them, of load balancing, of firewalling, of security policy, of the atomic unit that application processing architectures are built on top of, of management tools, and an evolution of billing/accounting models. Combine them, and yes in the end if you were to look at the current de rigeur state of computing and compare it to the possibilities hopefully enabled by the cloud models it would look REVOLUTIONARY.However, evolution takes time. And in that there is a distinct first-mover advantage that sometimes comes to bear- for instance as I commented in my reply to the GigaOm article we have been focused on virtualizing as much of our infrastructure as possible. It is not a quick journey, its not a simple feature, its not a hack. It’s a complete top-down and bottom-up redesign of many things that people take for granted. It’s looking at the hardware, the ASICs, the memory subsystems and controllers, resource schedulers, arbiters, and software operating systems designed with stateful process restart and fully separate and independent processes for each function. This takes a long time. For some functions the Virtual Appliance concept makes sense -- I have been an advocate of this for some of our own products for a long time. These would be product where the underlying hardware is not the source of differentiation or competitive advantage and having the appliance be capable of being ported from one class of machine to another could offer some intrinsic value or allow the customer to reuse processing cycles more efficiently. I can’t publish our road map and state which Cisco applications lend themselves best to this but lets say most things with deep packet inspection and encryption processing DO NOT lend themselves to virtual appliances very well. Given that caveat what applications do you want to see us release as virtual appliances????Now for the good news -- we’ve been preparing for this for over six years. From the first virtualized firewall to the first virtualized load balancer, to the Nexus 7000 and Nexus 5000 that enable the I/O itself to become virtual, or software provisionable as the case may be. We also brought out tools like VFrame to enable a simplification of the deployment and an automation of common IT workflows so we can speed up IT responsiveness and really become an enabler of Enterprise Clouds. Kind of a profound realization -- we have the tools today that can build Enterprise Clouds. At least the core infrastructure and a lot of the hard part- we still ahve work to do, and there are still significant organizational barriers to the deployment of some of these offerings. But they are maturing, and evolving.Our competitors are trying as well -- through their M&A strategy, or in another case through new management that may be a result of that same aforementioned M&A strategies execution path. All I can say is the next few years are going to continue to be very very fun….

For those of you going to going to the Next Generation Data Center conference in San Francisco in a couple of weeks, be sure to check out Rajiv Ramaswami‘s keynote: “Data Center 3.0: How the Network is Transforming the Data Center” (Tuesday, Aug 5th, 1:30pm). Rajiv is VP/GM for Cisco’s Data Center Business Unit. As both an industry and Cisco veteran, Rajiv has some great insight into what is on the horizon in the data center and how the network will accelerate key trends such as virtualization, collaboration, and new service models.

Beat this uptime

July 24, 2008 at 12:00 pm PST

We had an interesting thread unfold on an internal list, which I thought I would open up to our readership. Someone was foraging around the network and came across some impressive server uptime (all server names changed to keep infosec happy):

server-x% uptime7:13pm up 500 day(s), 3:17, 53 users, load average: 0.08, 0.11, 0.11

to which someone else countered with

server-y$ uptime23:45:15 up 700 days, 8:31, 3 users, load average: 0.00, 0.00, 0.00

The irony behind this server is that it has outlasted the business unit it apparently supported.
However, the winner so far is:

WS-C5000 Software, Version McpSW: 3.1(2) NmpSW: 3.1(2a)Copyright (c) 1995-1998 by Cisco SystemsNMP S/W compiled on Feb 20 1998, 18:56:57MCP S/W compiled on Feb 20 1998, 19:05:51System Bootstrap Version: 2.4(1)Hardware Version: 2.1 Model: WS-C5000 Serial #: 007584271…Uptime is 2618 days, 9 hours, 11 minutes


7+ years--guess there is something to that investment protection thing after all.
So what is the best system uptime in your data center? The response with the best uptime gets a Cisco fleece.

Initiative

This week saw the reactive execution of something we have predicted for a while- the consolidation of corporate entities to bring together LAN and SAN and try to challenge our Unified Fabric and Data Center 3.0 Vision. First I wanted to express gratitude for a multi-billion dollar valuation and endorsement of our vision that we started execution on in 2002. 2002 was when we first brought out our MDS 9500 Storage Director. It was designed with several key common architectural points with the Catalyst 6500- same Fabric ASICs, common equipment designs, etc. Subsequent to that we have evolved both platforms and introduced the Nexus 7000 and 5000 bringing FCoE to the market and delivering next-generation convergence platforms purpose-built for the data center and most importantly have delivered a strategic operating system that enables the convergence of these areas into a common hardware, silicon, and now software model- the key abstraction to the administrator/operator. It’s years of work, and we’re fortunate to have it finished.I personally don’t so much see this weeks news as the emergence of a new and stronger competitor as much as I see it as the loss of a respected adversary in the LAN market who played the game well….dgP.S -- US Principles of War for Offensives: Seize, retain, and exploit the initiative or if I was to paraphrase -- lead, don’t follow.

Nice Summary on DC Dynamics Conference

Ken Oestreich wrote this piece with a nice summary of the SF Data Center Dynamics conference.Even quoted our Greenest VP, Paul MArcoux on some of the areas we are seeing synergies between Campus, WAN, Data Center, Building Automation, etc. dg
