This Week A Lifetime In IT Is ThreeReal Years

Inspiration How long should your IT infrastructurelast In 1996 I was attempting to sell customers on the benefits of installingCategory 6 cable with the reassurance that copper cabling would be good for20 years It seemed logical when companies were signing 20shyyear leases ontheir buildings to have the cabling last the lifetime of a tenancy This was a different time in networking Token Ring FDDI and ATM were stillaround and Ethernet was increasing from 10MB to 100MB Category 5 hadntbeen invented and no one knew which Layer 2 protocol would dominate thefuture In 2015 I wonder how many businesses actually survive 20 years Howmany business stay in the same building for 20 years How many businesskeep the same floor layout decoration or office fittest for 20 years Fiveyears ago building leases were 5 years with first option on 5 more Today it

is common for building leases to be 3 + 3 What about routers firewalls servers and arrays Bandwidth amp storage isdoubling every 2 to 3 years Firewalls are now Next Generation and thenext generation of firewalls after that will have no way to break encryption Today budgets and business plans are measured in quarters with a longshyterm horizon of financial year Yet I talk to IT architects and their strategies are planned in decades withasset lifetimes of 5 to 10 years In networking enterprises buy backboneswitches in the data centre and campus with expectations of 10 years ofownership Thats a HUGE gap in expectations and planning between business and IT

Cost ImplicationsIf a business operates in quarterly cycles and has a financial horizon of 12months then at best a 36shymonth strategy can be justified as long term There is a substantial cost implication in purchasing a product for 10 years ofownership Like that 20shyyear guarantee I sold on cabling plant in 1996 therewas a significant cost to producing high quality products that would last Plusthe up market pitch generated far higher profit margins for manufacturerand reseller alike My rule of thumb is that high quality costs 200 moreCapEx than good enough for now My rule of thumb for 10 yearsurvivability is 300 in CapEx and 400 for OpEx Is that really worth it

Buying What You Need Now

Logically IT assets should have a 3shyyear lifecycle Selection criteria mustinclude the ability to cheaply rapidly and easily replace the physicalequipment For software selection criteria should include data portability sothat your word processor banking application or human resources platformcan be replaced at any time

My Second Law of Infrastructure (Law of Design Choices) 2 Good fast cheap choose only two 2a Anything free is worth what you pay for it

Im coming to the view that the last twenty years of IT has been dominatedby Good amp Fast Our attempts to make things cheap was achieved byreducing our value to the business The next 10 years is going to be Fast and Cheap We will spend the nextten years attempting to deliver value to the business with rapid asset rotationand fastshymoving software and theres not much good about that

Postscript and Virtual AppliancesVirtual Appliances are products that meet the need for short fast lifecyclesThey dont need dedicated hardware cabling or power They are easier toreplace and upgrade For some people subscription licensing means you canwalk away from them at any time Just make sure that you avoid fancy functions or vendorshyspecific featureswhen you deploy them

Augury SFP Modules DRM And PershyPort Licensing Ive been tracking a number of rumours that I havent been able to prove First I heard that Extreme Networks had implemented a DRM scheme on SFPmodules in certain models of its switches If you purchase and install an SFP

unit from Extreme then operation is normal Using thirdshyparty or OEM SFP willcause a licensing message to appear on console indicating that a pershyportlicense is needed to continue using the interfaces at full speed A license mustbe purchased and configured within 90 days or the port speed will reduce to25 That is a 10GbE will operate at 25Gbps 40GbE will operate at 10Gbeand so on Second I heard that Arista Networks has implemented full DRM on all SFPports in certain switch models Any use of OEM SFPs in the switch causes theport to completely disable itself and throw an error message I understandthat there is no workaround you must buy Arista SFP modules

Should I Be WorriedAgain I havent been able to confirm these stories but it presents a worryingtrend 1 Buying SFP modules from a vendor at substantial markup is a pershyportlicensing fee I doubt that most customers have realised this yet 2 In speaking with thirdshyparty OEM companies there is no technical reasonto use vendorshycertified modules 3 When purchasing a modern switch more than 50 of the totaldeployment cost is in the SFP modules when all or most ports on switch are inuse This cost is sometimes hidden when adding just a a few ports at a time(How many people actually price the full cost of a switch including SFPscables power etc) 4 Tracking the spare parts of certified SFP modules is a complete nightmare If you are forced through DRM to use vendorshycertified SFP modules what areyour thoughts

Guest Writer The Push Button DataCenter I am freshly returned from an event where I heard a number of data centerrelated vendors discuss their wares Nearly all of them were startups Startuptech companies are interesting in the data center space as they are oftenbegun by founders who have lived through IT pain then try to assuage thatpain Pain relief is a risky business The pain has to be poignant enough todrive demand for the product they create The pain also has to be longshystanding enough that it will still exist by the time their product comes tomarket A common thread I noticed in presentations was the idea that ldquoWe makeyour life easierrdquo In the case of the modern data center I donrsquot think startupsare taking big risks by trying to reduce operational complexity Data centermanagement is so challenging that products making the data center easier toconsume will gain customers The companies I heard from included Rubrik VMTurbo Data Gravity PernixData and Scale Computing As those are storage backup and virtualizationrelated companies you might wonder why I bring them up in a networkingshycentric magazine Consider this The data center is becoming highlyautomated Converged and hypershyconverged platforms have taken a smallbut significant share of the infrastructure market New data centermanagement tools are consumed by APIs Vendors are partnering with oneanother to deliver unified solutions There are several product options tomanage storage compute and virtualization in tandem The network is thelast silo to fall In speaking with what Irsquom loosely calling ldquoautomationvendorsrdquo about their approach to the network the general answer is that thenetwork is difficult to integrate but on their minds Networking is still hard to automate mdash still hard to consume Therersquos a lot ofnuanced detail to networking and it doesnrsquot help that most of us buildsnowflakes But snowflake network construction is not going to last foreverConversations around NFV frameworks and policy are moving networking to a

place where it too will be able to be consumed in a predictable way byautomation systems Networking will have to become predictable with feweroptions and nerd knobs required to deliver an effective transport The network engineer of the future will not merely have deep knowledge ofnetworking They will also know a lot about automation What networkelements are being consumed By what systems In what way And why isnrsquotit working as expected Knowledge of automation and comprehension ofother IT silos coupled with deep networking knowledge will be the callingcards of the next generation network engineer That will allow us to functioneffectively in the emerging push button data center

The pitches were either spoken aloud or read by the evaluators According to an article published in the journal Psychological Science ldquohellipevaluators rated a candidate as more competent thoughtful and intelligentwhen they heard a pitch rather than read it and as a result had a morefavorable impression of the candidate and were more interested in hiring thecandidaterdquo The study noted that the results were the same whether the pitches weregiven by trained actors or just regular people I prefer text when communicating both as a sender and a receiver As asender I can compose the message when itrsquos convenient for me and if Ihave time I can revise and rewrite As a receiver I can quickly scan a piece of text and often get the gist muchfaster than waiting for someone to talk it out But its also true the human voice carries nuances that dont always comeacross in writing including passion energy sarcasm and subtle emotionalcues And as someone who creates and listens to podcasts I know from my ownexperience that the human voice can resonate in ways that text alone cant So donrsquot forget your voice as a business tool Maybe the next time you needto pitch a new idea or train customers donrsquot send an email or a document Talk to people Look them in the eye Take advantage of the power of yourvoice If this study is right you might just come out looking smarter

You Need Business Continuity NotBusiness Connectivity

Most softwareshydefined wide area network (SDshyWAN)vendors today provide an extended LAN solution toprotect and connect enterprise locations We call thisbusiness connectivity What an enterprise really needs is an SDshyWAN solutionthat optimizes and ensures WAN availability We call this business continuity

For organizations with customershyfacing systems (Web site customer caresales etc) any application downtime has an immediate impact on revenueand customer satisfaction From an internal IT perspective when criticalapplications and data are not available employee productivity suffers asignificant reduction Customer and employee expectations mean that criticalsystems now require 100 percent uptime The key to limiting the impact ofsystem failure is to fix the problem fast by providing rapid (subshysecond)failover to alternative data center resources How organizations achieve thatis the challenge

Access to the continuously available data center architecture relies on a highshyperformance highly reliable WAN Advances in softwareshydefined networking

QampA Outspoken Public And CareerDamageQuestion

You seem like the noshyholds barred kind of guy that is always willing to speakyour mind even if your opinion is not popular Do you ever feel like that hashurt you in your career

Answer

The person you hear on the podcasts is not the same person in real life Ithink it is important to keep the show entertaining so that you listen to keepit interesting so it isnrsquot boring and to challenge the audience on certain ideasin networking Being a little crazy helps to keep it interesting and maybefun When Irsquom am working for clients or companies I am about listening

researching advising and covering the different options Speaking your mindhas a time and place but it must be backed up by knowledge research andreferences To prepare the podcasts and write blogs I spend many hours researchingtechnology briefing with vendors reading RFCs manuals etc etc beforefinalising the format and discussion topics Has this hurt my career I work freelance so I dont speak for my employer Ive never worked for avendor I never mention my employers anywhere I would guess that I missed a few freelance gigs for those people whoactually look you up on the Internet and get worried about that But then Ihave gained so much from being in public that its probably a fair trade

How Facebook Is Eating The $140 Billion HardwareMarket

Whenever I look at the OpenCompute Project I get the feeling that customserver hardware for the data center especially blade servers is history

Facebookrsquos extraordinary Open Compute Project is doing forhardware what Linux Android and many other popular productsdid for software making it free and open source

But revenues from blade servers and converged systems continues to growand Enterprises continue to spend (waste) big dollars on custom servers thatruns commodity silicon

ldquoI wrote a short paper circulated it to Zuck and the rest of teamrdquohe remembers referring to Facebook CEO Mark ZuckerbergHeiliger argued that the technology particularly the hardware ldquoisnot our competitive advantage and that open source should bea core tenet at Facebook

For an Enterprise IT hardware isnt a core function or competitive advantageThe real advantage is the software that runs and the design and operation of

that harware

Now that OCP has become a phenomenon Googles top hardwareshyinfrastructure guy (a legend in his world) Urs Houmllzle offers abegrudging respect for the project

Google considers its hardware (network storage and compute) as part of itsmagic powers and core business advantage But Facebook is now gaininglower hardware costs by encouraging wider participation which leads tovolume manufacturing which leads to lower risks for setting up the productionline and investing in producing Open Compute hardware

Flash forward to March 2015 Over 2500 people came to USconference held at the San Jose Convention Center OCPs newfullshytime CEO Corey Bell tells us

Open Compute hardware is growing in popularity I have spoken with manycompanies who are conducting early stage tests on building private cloudswith the hardware The universal fact is that unique or vendor brandedhardware is expensive and not needed for a true cloud architecture It doesntnecessarily repalce existing software but future applications are planned torun on full cloudshystyle systems Link How Facebook is eating the $140 billion hardware market

How To Receive A Million Packets Per SecondThis article talks about configuring Linux to handle 1 million UDP packets persecond

That got me thinking While I agree that 50kpps per core isprobably the limit for any practical application what is the Linuxnetworking stack capable of Lets rephrase that to make it morefun

Most network engineers would immediately consider implementing a loadbalancer and tens of servers to handle the load But with some Linux skillsand serious Linux knowshyhow (also googleshyfu) you can handle a vast amountof packets

First IP receive queue is linked to single CPU core Which is silly there arealways 4 or more CPU cores in a modern server (bare metal)

To utilize multicore systems NICs began to support multiple RXqueues The design is simple each RX queue is pinned to aseparate CPU therefore by delivering packets to all the RXqueues a NIC can utilize all CPUs But it raises a question given apacket how does the NIC decide to which RX queue to push it

Since the hashing algorithm on our NIC is pretty limited the onlyway to distribute the packets across RX queues is to use many IPaddresses Heres how to send packets to different destinationIPs

OK getting harder Having multiple IP addresses needs some networkingskills to understand what an IP address is and how to have more than one ona single server

While we had shown that it is technically possible to receive1Mpps on a Linux machine the application was not doing anyactual processing of received packets shy it didnt even look at thecontent of the traffic Dont expect performance like that for anypractical application without a lot more work

OK caveat emptor Except it comes for free Anything free is worth what youpaid for it

State And ConfigurationOne of my favourite pastimes is watching exshyCisco employees discover aworld that doesnt have allshyciscoshyallshytheshytimeshybeingshytheshyonlyshyanswershytoshyeverything

Having spent my entire career with Cisco (working with IOS andNXshyOS) until recently I never realized there was a differencebetween the state of a system and the configuration applied to it

ORLY

Itrsquos important to understand that state and configuration aredifferent ideas In software like IOS the configuration is always thestate In software like IOSshyXR or Linux you can have configurationsomewhat independent from state allowing for syntax ordependency checking first before applying state Finally Linux cantake it a step further and allow for state to be applied withoutconfiguration

Congratulations welcome to five years ago Linux makes sense but not forthe reasons that you think
