Collection of useful, relevant or inane places on the the Internets for 26 May 2011:
- Cisco UCS Market Share – Q1 2011 | Jeff Said So – So much overblown ego in this post but the numbers:
This chart is quite telling. Not only did the adoption of UCS begin immediately, it has accelerated drastically since 2010 and hasn’t slowed. It’s a major contrast if you compare the growth of UCS with the fall of HP Bladesystem. It’s also clear that Cisco UCS is tremndously outpacing the rest of the x86 blade server market. There are years of innovation in UCS and customer demand is clear proof that we’re solving real business problems. It also doesn’t hurt that we’ve set over 40 record-breaking benchmarks along the way.
I’m sure they worked hard, but this type of gloating isn’t pleasant. It’s childish. IT Infrastructure isn’t a game where the score matters, it’s serious business – I expect people to act better than this.
- The Cisco Connection: Cisco lost switching share in Q1 – Jim Duffy at Network World on some numbers from an analyst.
Cisco’s share in Layer 2/3 dipped to 69% from 71% in Q4 due to the product transition underway and heightened competition. Cisco’s switching sales slipped 15% from Q4, to $3 billion, according to Oppenheimer.
HP’s share climbed to 12% from 10%, even though revenues were essentially flat. And Juniper lost a bit of share – to 2% from 2.2% — as customers contemplate the transition to the new QFabric line.
The Cisco uCS team are crowing about their server number, but the overall story is bad for Cisco. Highlights the lack of integration in the business. Server success is built on network success not because the product is that great – it’s just Intel chips glued to a board like all the others.
- Cisco IOS Hints and Tricks: Scalability of Common Services MPLS/VPN topology -
Common Services VPN topology is hard to use in typical service provider networks as it requires non-overlapping customer address space (as Nosx said: “It created far more problems than it solved, and better solutions (more secure, more scalable, more managable) are available now”).
That is the sound of bitter experience, listen and learn.
- I, Cringely » Blog Archive » InsecureID: No more secrets? – Cringely on technology -
Last weekend was bad for a very large U. S. defense contractor that uses SecureID tokens from RSA to provide two-factor authentication for remote VPN access to their corporate networks. Late on Sunday all remote access to the internal corporate network was disabled. All workers were told was that it would be down for at least a week. Folks who regularly telecommute were asked to come into nearby offices to work. Then earlier today (Wednesday) came word that everybody with RSA SecureID tokens would be getting new tokens over the next several weeks. Also, everybody on the network (over 100,000 people) would be asked to reset their passwords, which means admin files have probably been compromised.
Looks like the RSA hack was worst case. Contact RSA and get new tokens (once you ask they will replace them).
- Cisco Borderless Campus Design Guide V1.0 – PDF Version – This is the PDF version of the Cisco Borderless Campus Design Guide. Everyone should have this on their hard disks, ready for reference and constant use. Not only outlines the design and architectural information for deploying Cisco Campus networks but also implementation, troubleshooting, CLI and much more.Another triumph of technical marketing from Cisco. One that no other networking company seems to be able to do. Bravo.
- Juniper: Auriga Cuts To Hold; Watch Out For OpenFlow – Tech Trader Daily – Barrons.com – Packet Pushers get a plug on Tech Trader Daily at Barrons. Huh.
You can read more about OpenFlow at the Stanford development Web page; or read the white paper on it; or listen to this very nice podcast from PacketPushers.
- Insult to injury: San Francisco wins $1.5M from Terry Childs | Data Center – InfoWorld – This is a step too far. The guy may have been overzealous, and overcommitted but he didn’t do anything to deserve this treatment.
Insult to injury: San Francisco wins $1.5M from Terry Childs It’s abundantly clear that San Francisco is making an example of Terry Childs. But for whom?
- newsapps/beeswithmachineguns – GitHub -
A utility for arming (creating) many bees (micro EC2 instances) to attack (load test) targets (web applications).
Mwuh uh uh hahhhhhahhhh. Meant to be for load testing for applications but I can think of other things……….
- ntop » Going beyond RSS (Receive-Side Scaling) -
It’s now time to use multi-queue RX adapters
When building high performance, low latency systems the network adapters are key. This is just one limitation – but it’s a good start.
- Perspectives – Software Load Balancing using Software Defined Networking – James Hamilton (now at Amazon and previously Facebook ) makes the case for OpenFlow. You can’t learn anything from FaceBook or Amazon but here is someone keen on OpenFlow.
I invited Nikhil Handigol to present at Amazon earlier this week. Nikhil is a Phd candidate at Stanford University working with networking legend Nick McKeown on the Software Defined Networking team. Software defined networking is an concept coined by Nick where the research team is separating the networking control plane from the data plane. The goal is a fast and dumb routing engine with the control plane factored out and supporting an open programming platform.
- mnot’s blog: On HTTP Load Testing – When benchmarking, you need to be very careful about what throughput you are measuring:
1,000 because of TCP overheads).
Once you know the bandwidth available, you need to make sure that it isn’t a limiting factor. There are a number of ways to do this, but the easiest is to use a tool that keeps track of the traffic in use. For example, httperf shows bandwidth use like this:
Net I/O: 23399.7 KB/s (191.7*10^6 bps)
… which tells me that I’m only using about 192 Mbits of my Gigabit in this test.
in this example, the network isn’t the limiting factor, but it very often is. Great article on benching HTTP servers.
- Fulcrum Microsystems Blog » Blog Archive » Will Data Center Bridging Save the FCoE Market? – Probably not.
So what happened? Q4 2010 sales reports saw customers move to 10GB Ethernet and 8 GB Fibre Channel, but not move to FCoE in large numbers. The Register reports on a Dell’Oro Group report that shows record sales of more than 900,000 FC ports shipped in the fourth quarter of 2010. Sales volumes of 10GB Ethernet adapters and controllers rose 57 percent in the same period, to just under $100 million.
Unsurprisingly, customers aren’t seeing the value in FCoE. Maybe that is why Cisco is being extra friendly to NetApp – the numbers are not good enough to bet the company on FCoE. That said, FCoE is a nice way to integrate legacy FC into your new data centre, but that’s about it.
- Is Cisco on the Outs With EMC, VMware?: Cloud Computing News « – GigaOm article on Cisco getting close to NetApp:
Perhaps the NetApp partnership is a tactic to get a bigger piece of the VCE pie. Or perhaps it’s the prelude to an acquisition that wouldn’t leave Cisco beholden to storage partners at all. Suggestions that Cisco will buy its way into the storage business to complement its server business are nothing new, after all, and NetApp would make Cisco a storage big shot immediately.
Current view is that Cisco was to spread their risk out, instead of buying either EMC or NetApp. Uncle John is having a tough time at work with failed strategies and an acquisition isn’t a good move when you are divesting other businesses – stock markets don’t like that.
- Why geeks make better adults than the in-crowd – Yahoo! News – Not news to most of the people I know:
In good news for nerds everywhere, what makes people unpopular in the hallways of high school, mainly an unwillingness to conform, tends to translate into success as an adult. Robbins lists several companies—including Yahoo!—that prioritize hiring quirky individuals who shun conventional thinking. She also name-checks historical and current celebrities, including director Steven Spielberg (who was taunted for being Jewish in high school) and Lady Gaga (a self-described former theater “freak”), whose weirdness led to later fame. (Other now-validated former outsiders she touts: Steve Jobs, Taylor Swift, Bruce Springsteen and Angelina Jolie.)
Willingness to change, be changed and create change is an identifying feature of IT. At school, I was forced to conform and be quiet. Neither of these “talents” was useful in real life.
