The Software-Dened Data Center andthe Promise of End-To-End Orchestration

If youre like me, youre tired of IT terms like cloudor convergence being tossed around as marketing hype. And phrases like software-dened data center and soft-

ware-dened storage are starting to inspire eye rolling. After all, these days it seems that if something is software-dened, its got to be bettereven if we dont know why.

Software-dened networking (SDN) is a more devel-oped concept than software-dened storage, for example.Most articles on software-dened storage still begin witha discussion of what that real ly means. But Ive come tounderstand that when it comes to the data center, the software-dened concept means one thing: the potential for

end-to-end orchestration. And thats exciting business.The promise of server virtualization and cloud com-

puting has been the automated provisioning of computeresources, but network and storage havent been able tochange rapidly enough to support VM provisioning andmigration.

Yet a software-dened data center ecosystem canchange all of that. With SDN, we can build programmable,agile networks by reaching into the forwarding or data

plane to decide where specic ows should go. We caneven spin up virtual network instances on demand. Withsoftware-dened storage, we can abstract the operating

system, hypervisor and services controller for rapid provi-sioning and ne-tuned control across storage systems.

The software-dened data center will be integratedacross systems so that these interdependent resources canbe spun up together on demand, as needed. The larger software-dened data center ecosystem will mean that we canplug in any commodity server, network or storage hardwareand use common software to abstract granular control ofthese resources. With that, data center convergence (one

of those hyped IT terms) would nally become reality.In this issue of The New Network , we explore what lies

behind the software-dened data center. We hope it willshow you the path toward that weve long envisionedtotalorchestration and automation in a virtualized environ-ment. n

With SDN, network engineers

will eventually be able to

improve security, management

and application performance

in the LAN and WANwithout

costly hardware.

software defined networking (SDN) is alreadychanging the data center network, but now the technologycould redene other parts of the network, as well as thenetwork engineering profession itself.

A host of start-ups, academic researchers and other network gurus are exploring the powerful exibility and pro-grammability of SDN for strategies to make the LANs and WANs of tomorrow simpler to manage, more secure andmore powerful than ever before.

At the forefront of many SDN researchers minds issecurity, particularly in environments that already relyheavily on virtualization. SDN will offer better control overnetwork traffic, allowing engineers to differentiate networkaccess for users in order to identify and separate bad actorsor simply incompetent users.

What is talked about most is security and the ability tounderstand or customize hosts on your LAN network, saidMat Mathews, co-founder of Plexxi, a networking start-up

betting heavily on SDN advances.Today, those capabilities are vendor dependent. Cisco

and Juniper, for example, have gone to great lengths tobake security into their networking hardware , but these so-lutions dont necessarily integrate well in a mixed-vendorenvironment. Nor do these capabilities translate well if you want to manage your security through a third-party vendorthat doesnt partner with your switching provider.

That will change if open, standardized SDN catches on.

TOWARD A UNIFIED SDNSECURITY SOLUTION

Researchers are currently exploring how to use SDN toprovide segmented, virtualized networks based on thecharacteristics of the connecting device, such as IP or MACaddress. This would allow companies to give authorized us-ers full network permissions while connecting guests to acompletely partitioned network that restricts their accessto le shares, printers and other sensitive areas.

SDN could also help nd and eliminate threats thatcome from within a network, whether its a cloud provider working to prevent malicious users or a university campustrying to stem the tide of a nasty virus. This was one of theexciting avenues of research for Ben Cherian, chief strategyofficer of Midokura.

Lets say that a DDoS attack is originating from your[public] cloud, and you have no idea who is doing this. Youcan handle that by having physical people watching the

network or you could set rules on your network, and sayI am going to tap all the traffic on my cloud, and if I seesomething abnormal, Im going to programmatically shutdown the tenants that are abnormal, Cherian said.

The latter option not only requires fewer staff, but itscales up more easily. It also leaves network security lessprone to human error. Midokura has already developedand deployed a port mirror that clones traffic for analysis,allowing increased security without compromised speed.

SDN OFFERS UNLIMITED POTENTIALIN NETWORK SERVICES AND APPS

As SDN advances, it will enable new applications that areunimaginable today. Instead of buying rewall or WANoptimization appliances, for example, enterprises could work with start-ups that are developing alternative SDNapplications that can be installed and scaled on a virtual-ized network.

Kyle Forster, cofounder and vice president of Big Switch

Networks, is building the company around that very idea.We have 15 apps in the pipeline, including a rewall, hesaid. But whats exciting are the new capabilities SDN ap-plications will have in monitoring and redirecting networktraffic in real time.

The wonderful thing about having a programmableLevel 2/Level 3 network is that if youre a Level 4 or Level7 application provider, you can do a small adjustmentto get the right packets to [you r appliance] at the right

time, Forster said.Thats a level of direct access that used to require pricey,

specialized hardware investments. In time you could im-plement these capabilities on an SDN network quickly andinexpensively, dramatically changing the speed and ex-ibility of how networks are managed.

RETHINKING THE SPEED AND STYLE

OF NETWORK ADMINISTRATION

While being able to access data streams in new and innova-

tive ways could provide a wealth of new networking appli-cations, the most lasting change could be in how networksare managedand the skills required to manage them.

As networking gets more integrated into the virtual-ized part of IT, the software people will be running things,said Dan Pitt, executive director of the Open NetworkingFoundation. If people can write automatic scripts forconguration and dynamic management, they dont haveto get their ngers dirty with ports and VLANs and other

problem areas.That doesnt mean the network engineers of the future

should forget everything they learned studying for theCCIE and start brushing up on their Python (yet). It couldmean that they should start thinking about new services

that can be delivered and have a positive business impact. With the right frame of mind, engineers could help movethe network from being a cost center to a business driver.

We like to say, What can we do to make network engi-neers heroes again? Its been a long time since weve seenthat, said Forster. [SDN] increases their ability to grabapplications when they need them to make their networksmore useful.

Plexxis Mathews echoed that assessment. What hashappened is that the toolkit available to sys admins tomaintain, operate and orchestrate compute resources has

expanded, Mathews said. Theyve changed their positionto be more like DevOps.

So what can forward-thinking network engineers doto prepare for the coming wave of SDN? I would counselthem to be the advanced scout for their enterprise; showtheir enterprise how they can exploit SDN and do it [in]conjunction with the current installed base, said Pitt.Some [networking] jobs will be going away, and the people who lead the charge in how you [transition] in a productive

way will be the ones the enterprise want to retain.Staying open-minded might not hurt, either. I dontthink the network is going away or this role is going away,but theres a different breed of person who needs to man-age it, said Cherian. n

Data CenterNetwork Fabrics

vs. Software-Dened Networks

BY SHAMUS MCGILLICUDDY

Are data center fabrics and

software-dened networks

competitive or complementary

technologies?

just last year, data center network fabrics were thehot topic in networking. Flat, low-latency networks with

any-to-any bandwidth promised to solve the network-ing problems of highly virtualized data centers. Thesefabrics would enable increased east-west traffic inandfree up bandwidth constraints created byspanning treeprotocol (STP), making networks responsive to server vir-tualization and resulting in easier-to-operate data centerinfrastructure.

Then something else happeneda tsunami of hype hitthe networking industry in the form of OpenFlow and soft-

ware dened networking (SDN). Startups emerged withclaims that SDN could enable programmable networks inmultivendor environments, solving many of the problemsthat expensive data center fabrics promised to x, but for a whole lot less money.

Now network engineers and architects must sortthrough two separate hype machines. And they must ask whether data center fabrics and SDN are an either-or prop-osition, or two architectures that complement each other.






7/16


The answer to this question is hard to nd, particularlybecause fabrics and SDNs are still very new to the market.Few enterprises have moved beyond the proof-of-conceptstage with fabrics, and the availability of robust, commer-cial SDN products remains scarce.

In fact, SDN is still evolving, and the use cases for it arestill developing. Whats more, every vendor has its ownself-dened data center fabric offering, but most are alsocooking up SDN plans.

Proponents from either camp will tell you that their sidecan solve most data center networking needs. However,

theyll also concede that there is room for both.The goals [of SDN and fabrics] sound the same, but

abstracting the network to extract complexity is one thing,and then fundamentally simplifying the infrastructure isanother thing. The two working together can be extremelypowerful, said Mike Marcellin, vice president of product

marketing and strategy at JuniperNetworks.

If you simply abstract the com-

plexity like an SDN is trying to do,that can help. But if the fundamen-tal architecture is still complex, ifits still brittle, if you have to keepthrowing more devices at the prob-lem to scale the network, thenthe root of the problem is still notaddressed, Marcellin said.

Dan Pitt, executive director of

the Open Networking Foundation, which governs the de- velopment of OpenFlow, concedes Marcellins point to apoint.

You could choose one or the other, or you could choosea combination, said Pitt. But I think if a customer has abrand-new choice, a true SDN solution with its inherentbenets and with its many choices in how they procure anddeploy it [that will be their choice].

SDN IS NOT QUITE READY TO REPLACE

INNOVATIVE HARDWARE When SDN and OpenFlow hype rst started taking off,some industry observers predicted that OpenFlows abilityto centralize the control plane of a network would com-moditize network hardware. Switches and routers wouldbecome dumb boxes pushing packets back and forth, andthe brains of a network would live on a server. However, re-ality has since started setting in.

The less reasonable part of the [SDN] discussion is

whether network companies are dead because youngentrepreneurs can come along and buy a few parts fromthe silicon vendors and build stuff that is equivalent to what switch vendors do, said Peter Christy, principalanalyst with Internet Research Group. I think that partis unrealistic because high performance, highly reliablefabric that operates on 40 Gbps links is pretty interestingengineering.

Also, SDN remains more of a curiosity for enterprises,

Every vendor has its ownself-dened data center

fabric offering, but most arealso cooking up SDN plans.

The rst piecethe physical networkis not trivial.Software people dont understand how hard it is to build a

physical network that is reliable and manageable. And oneof the hardest problems is [how] to use all the connecting wires on demand for whatever needs to be done at that mo-ment. That is a difficult problem, and it is the kind of thingthat network vendors like Cisco, Juniper and Arista do very well, Christy said.

Then there is the communication between the virtualmachines, which increasingly you need to deal with in therealm of software. The problem you run into with tradi-

tional networking is when things become more dynamicand when more of the operationmoves into the software at a higherlevel.

Big Switch Networks, an SDNand OpenFlow startup, has at leastone joint customer with JuniperQFabric, according to Kyle Forster,co-founder and vice president of

marketing at Big Switch. And heanticipates having many more, not just with QFabric but with data cen-ter fabrics from Cisco, Brocade andothers.

Software-dened networkinggives you the functionality, and afabric gives you the bandwidth,Forster said. If you want to place

any virtual machine anywhere and you need to get sub-nets and VLANs fundamentally out of the way, you need a

whole lot of management functionality. Most of that, and inmy opinion, all of it is in the software dened networkingcamp.

A data center fabric can guarantee an enterprise equalbandwidth no matter where it chooses to place a virtualmachine within a data center. As those VMs move around,the functionality of an SDN comes into play.

The joint QFabric customer, a cloud provider that catersto the healthcare industry, offers a multi-tenant environ-

ment for its customers. In that environment, it rep licates ahospitals existing data center.

Over time, the cloud provider dynamically evolves thoseenvironments, moving VMs and other resources around toreduce its own internal costs. However, as it alters its in-ternal network to support the migration of those resourcesthroughout its data center, the cloud provider wants thatnetwork to remain transparent to its customers, Forstersaid.

That means that the bandwidth guarantees had to bethere [from QFabric] as [the provider] moved physicalservers or virtual machines around. And he really neededto be able to place any physical server or virtual machineanywhere in the data center as he cost-reduced, Forstersaid.

He wanted to be able to do that without saying tothe customer, Oh, hey, due to funky reasons that aremore my problem than yours, I want to change your IP

addresses. That would be very distasteful to a customerrelationship.

This is an extreme case of [a customer] wanting to getthe network complexity out of the way and the VLANs andsubnets out of the way, Forster said. Were giving him allthe Layer 2/Layer 3 functionality, and QFabric is givinghim all the bandwidth.

EVERY NETWORK FABRIC VENDOR IS BUILDING

AN SDN STRATEGY

If you have any doubts on whether fabrics and SDNs arereconcilable, look at the fabric vendors. Cisco, Juniper,Brocade, Extreme Networks, Dell Force10 and Arista

Networks are all articulating and evolving SDN visions.They are working to nd points of intersections between

the two categories of products.I cant speak for any vendor, but I suspect that every

vendor is thinking about their migration strategy [to SDNand OpenFlow], said Pitt of the Open Networking Foun-dation. The general notion of fabrics is a really good idea.They are proprietary solutions that seek to solve some ofthe same problems that we are addressing with OpenFlowand software-dened networking in general. I think someof these original [fabrics] were by necess ity proprietary,

but I dont think theres much of a need to stay proprietaryfor much longer since we have a standardized approachthats now in the market. n

Is IT Ready for theSoftware-DenedData Center?

BY ALAN R. EARLS

Vendors are consumed with

talk about the software-deneddata center, but are IT

managers really there yet?

It used to be that a data center was a unique and recog-nizable place, marked by certain physical attributes.

Historically it has been known for its glass walls, hum-ming equipment, and special heating, vacuum and air-con-ditioning equipment. As equipment has shrunk in size andbeen dispersed or hidden, and as machines have becomemore virtualized, the old data center has begun to fadeaway.

Still, even with increasing levels of virtualization, manydata centers remain repositories for physical infrastruc-ture that is struggling to keep pace. Technology trends such

as cloud computing and even the bring your own device(BYOD) trend are putting pressure on IT departments tomodernize the data center topography to create even moreexible services with better performance and security.

The software-dened data center (SDDC) may be cen-tral to that shift. The concept behind this approach is tobring every aspect of an IT environment to parity through virtualization. As a result, all infrastructure is delivered asa service and automated by software.






12/16


BANG FOR THE BUCK

The potential of an SDDC is apparent in the challenges

for James Patterson, COO of Toronto, Ontario-based BPSResolver, a software company that delivers compliancetechnology via Software as a Service (SaaS). But his com-pany wanted to focus on its product, not on supporting in-frastructure, so it turned to hosting company CentriLogicto provide a home for its offerings. For the most part, saidPatterson, he has been thrilled with CentriLogic, whichrelies heavily on virtualization technology to support shift-ing customer demand. However, said Patterson, despite

CentriLogics continued effort to improve its capabilities, when a change in network conguration is required, unlikethe near-instantaneous response for server and storagechanges, it takes a lot longer to implement.

The culprit, he suspects, is the fact that virtualizationtechnology has not yet owed into the world of switchesand routers, which still depend heavily on manual andsometimes even physical reconguration to adapt to newdemands.

Thats why theres a growing buzz around the conceptof SDDC and a key enabler, software-dened network-ing (SDN). Indeed, said Brandon Myers, an engagementmanager at SWC Technology Partners, a Chicago-areaIT consulting rm, Companies are beyond ready for thesoftware-dened data center. SDDC provides options toadministrators that they have wanted for a long time butcouldnt afford.

The term SDDC crystallizes the convergence of two core

concepts: a fully virtualized environment and the presenceof cloud computing, according to Jim Damoulakis, CTO at

Southborough, Mass.-based GlassHouse Technologies, aconsulting and advisory rm. The main benet of SDDCfrom a private cloud standpoint is its ability to deliver bet-ter efficiency, exibility and agility, he said.

Damoulakis said that while server virtualization has cre-ated a revolutiondramatically reducing server provision-ing times from weeks to hours, for examplethe picturefor storage, and especially for networking, has been lessfavorable. The net result has been to reduce overall infra-

structure exibility. The vision that SDDC represents hasbeen to wrap the entire environment with automation byadding a layer of management. As a result, changes becomerepeatable, low effort and consistent, he said.

Damoulakis said the term software-dened data centerappears to have originated with VMware Inc., the virtual-ization company. They are a software rm, and softwarerms tend to view things in software terms, he said. I would prefer software-enabled, because software is the

tool set and what you should be doing is focusing on solvinga business problem, not simply imposing a software visionon things.

EMERGING CAPABILITIES

Eric Hanselman, research director for networking at 451Research in Boston, agrees that the SDDC is about improv-ing integration as well as about automation. The goal is






13/16


to take activities that often involve physical changes andmanual processes and integrate them with other, more au-

tomated data center practices, he said. The starting pointis virtualization. You have to have a certain amount of ab-straction to deal more exibly with the various resources,said Hanselman, but the real value is achieving a higherlevel of management integration. It doesnt have to becloud initially, but it is going to look like cloud.

SDDCs prime goal is to make it eas ier to change server,storage and, in particular, network congurations. It doesso, he explained, by automating partitioning of the entire

data center infrastructure and spanning that architecture,and by scaling and thus delivering much greater efficiency.

At the moment, it is still early days for SDDC adoption,Hanselman said. So far, it has been mostly the kinds of or-ganizations that are building hyperscale data centers thathave had to pioneer and blaze a path. There have been

some widely discussed implementa-tions, particularly Google, he said.Google has done interesting things

to dynamically shift internal capac-ity using homegrown applicationsand their own OpenFlow controlswitches, he said. That has been fur-ther supplemented by having a dy-namic scheduling system that shiftscapacity as systems perform moretraffic-intensive activities such asreplication.

In SDDC there are currently two major players, accord-ing to Hanselman: Nicira, with its Network Virtualization

Platform (NVP)which enables the dynamic creation of virtual network infrastructure and services that are com-pletely decoupled from the physical network hardwareand Big Switch Networks, which offers what it calls OpenSoftware-Dened Networking. Hanselman said both com-panies aim to use virtual connections across virtualizedenvironments and then extend reach through tunnels intoother virtualized environments.

But other companies have or are developing capabilities

in these areas. Brocade, for example, offers the ability totake a tunnel that starts in a virtual world and terminate itin a physical device.

Hanselman said SDDC can boost data center efficiency.With virtualization, we improved the efficiency of indi- vidual servers. SDDC starts with the same situation for thedata center, he said. Where in the past you had to dedi-cate a server for a database or other application, now youcan divide resources as needed.

We have moved from an architecture where, becauseof the network, you had to build pods or tiers; now SDDCpermits tasks to move around, said Hanselman. Further-more, in the past, a data center was limited in its ability tomove applications that needed high performance becauseof the limits of the Fibre Channel connections. With SDDC,the SAN is connected to a network environment that canabstract the connection to wherever the server is used, asneeded, using iSCSI or Fibre Channel over IP.

SDDCs prime goal isto make it easier to

change server, storageand, in particular,

network congurations.






14/16


To make this work, especially for storage, you need highperformance; what SDDC does is take advantage of soft-

ware networking capabilities to ensure it has the neces-sary performance, said Hanselman.

Efficiency will be particularly appealing to some, saidNick Lippis, publisher of The Lippis Report, which targetsIT and network decision makers. He said that SDDC hasevolved in part as a result of the pressure on virtualizationcompanies to have more highly integrated stacks and forthose stacks to have automated provisioning attributes.We have distributed computing with centralized automa-

tion and one-person management, but in networking westill have operational bloat, he said. The end users dont want to have to keep adding people as the networks grow.

Up until now, said Lippis, networking has been an oli-gopoly, with relatively few players and with ease of man-agement as an afterthought. Lippis compared SDDC to

the revolution in home entertain-ment, when the universal remotestarted to allow easy control of mul-tiple devices from one pointsim-plifying both conguration and use.Once you have everything wiredand you have centralized controlabstraction, then you can start do-ing interesting things to control anetwork, Lippis said.

In the SDDC vision, everythingis wired once, then network agents

can manage devices and protocols. Hopefully at somepoint in time we will see applications simply requesting

services from the network, but clearly we are not thereyet, said Lippis.

He noted that a lot of activity is happening relative toSDDC in the Open Networking Foundation, which is devel-oping standards for open networking and software-denednetworks.

Lippis helps host an open-networking user group. Wehave support from large companies like Fidelity and JPM-organ Chase & Co. All those rms are involved because

they have a problem, he said. In the IT networking world,there is a ratio of about one engineer for every 50 rout-ers, whereas in the mobile market, companies like Sprinthave one engineer managing thousands of endpoints. Thatis why these companies are making such a big push forSDDC.

Further, said Lippis, The larger IT buyers are startingto meet with startups in this space; they dont really wantthe large network vendors there because they dont believethey have an interest in making this technology happen.

The advantages of SDDC arent just hype, said ArunTaneja, founder and analyst at the Taneja Group. Auto-mation means you can set and achieve quality-of-servicetargets and really treat the whole physical infrastructureas a pool, he explained. A lot of the physical structure maystill look familiar, but with SDDC you will have the abilityfor applications to nd the connectivity they need at theperformance level they require, without having armies of

In the SDDC vision, everythingis wired once, then network

agents can managedevices and protocols.

people to manage the process, he said.In the age of the cloud, said Taneja, there is no way

humans can manage the thousands of elements in theinfrastructure.

Conceptually, he said, unlike traditional deterministicnetworks, where humans dene the pathways, SDN andSDDC, like the Internet, rely on heuristic approaches tond optimal paths.

What we have learned about virtualization so far is thatsolving two parts of the problemcomputing and storage just shifts the bottleneck somewhere else, namely to the

network, said Taneja.

CAUTIONS AND ADVICE

A missing piece in most discussions of SDDC is the busi-ness process and policy denition aspect, said Damoulakis.The technology breakthroughs are important, but youneed to have a plan in place to use the technology in an

effective way, he said. Otherwise you are getting a tool set,but you dont know what you are building. IT is often guilty

of overprovisioningbuilding just in case instead of just intime.

Damoulakis said although SDDC clearly offers advan-tages, there are complexities and pitfalls, especially relatedto vendor selection. This falls straight in line with themovement toward the private cloud, he said, but you stillhave to look at how some of the components have beendened and, in some cases, maybe wait for clarity and aclearer sense of direction.

A starting point for investment decisions is reviewingyour existing technology. A legacy application running ina traditional data center model, for example, may not be agood candidate for SDDC. However, there is a clear use casefor SDDC with higher-volume and standardizable servicesthat IT is regularly called upon to deploy, Damoulakissaid. Those could be better handled in a fast and efficient way through SDDC. n
