A look at the dashboard for Nimsoft NMS Unified Monitoring.

CA today continued its cloud computing buying spree, announcing that it has signed a definitive agreement to acquire monitoring provider Nimsoft, Inc. for $350 million in cash. The deal follows CA’s recent acquisitions of Cassatt, NetQoS and Oblicore and the planned acquisition of 3Tera.

Nimsoft offers “unified monitoring” that can monitor and benchmark data center environments as well as Google Apps, Rackspace Cloud, Amazon Web Services and EC2, Salesforce.com and other cloud environments services. A complete API is available to both customers and third party developers to enable extensions to NMS.

CA said buying Nimsoft will boost its offerings for enterprises and MSPs. “With our planned acquisition of Nimsoft, CA will be equipped to capture several important growth market segments—including emerging enterprises, emerging national economies, and the MSPs who are providing these customers with IT management services via the cloud,” said Chris O’Malley, CA’s executive vice president, Cloud Products and Solutions Business Line. “Penetration of these markets will further expand our global leadership in IT management and complement our existing strength with large enterprise customers.”

Nimsoft was originally established as Nimbus Software in 1998 and renamed Nimsoft in 2004. It has approximately 800 customers, including nearly 300 MSPs and operates primarily in the United States and Europe.

“CA and Nimsoft are a perfect match,” said Gary Read, Nimsoft president and CEO, who will be joining CA. “We are joining a company that wrote the book on enterprise management. We’re bringing a very strong track record of success in the hosted and managed services segment and with mid-market enterprises. CA clearly shares our commitment to address customers’ evolving requirements for the management of their IT systems, including their move to virtualization and the cloud.”

Nimsoft’s operations will report under CA’s Cloud Products and Solutions Business Line. It is anticipated that the majority of Nimsoft’s approximately 120 employees will remain with CA after the completion of the transaction, which is expected to close by the end of CA’s fourth fiscal quarter, ending March 31, 2010. The acquisition is expected to have minimal impact on fiscal year 2010 results and to be dilutive to earnings per share in fiscal year 2011.

Cloud computing represents a new way to deliver and consume services on a shared network and IT infrastructure. Previously, IT hardware and software were acquired and physically provisioned on site. With cloud computing, the value of these same software and hardware products are delivered on-demand in the form of services over the network. Cloud computing is not only relevant to network service providers or internet-based service providers offering cloud services to customers, enterprise or public sector IT organizations are becoming acutely aware of cloud computing’s relevance to their own internal operations.

It is now possible for IT to build out private clouds or augment their resources with public clouds that enable their data centers to benefit from this powerful computing model. The lessons learned from cloud computing can vastly improve the scale, agility, and application service levels of enterprise data centers as well as reduce costs. Achieving these results requires close examination of the network itself, which is the foundation of the cloud-ready data center.

It can be daunting to interconnect a growing number of virtual and physical devices while trying to simplify the network to manage these resources at scale. Management complexity increases exponentially as more devices are added. This often necessitates physical segmentation, which runs counterintuitive to building large, shared resource pools that maximize economies of scale.

Overcoming these obstacles requires a fundamental shift in the way enterprise IT organizations build-out their legacy data center networks. Success in building a scalable, cloud-ready data center network requires following three critical steps: (1) simplify, (2) share and (3) secure.

Simplify
Simplification starts with reducing the number of autonomous devices. In the future, a single logical switch will be able to scale securely and reliably across the data center to connect all servers, storage and appliances. Until that happens, interim measures can be taken to consolidate network layers, increase scale and performance without adding complexity and reduce costs:

• Leverage device density to reduce the number of physical devices.
  Employ technologies that enable multiple physical devices to act as one logical device.
  Reduce layers of switching to two or less.
  Ensure reliable routing connections into and out of the data center.
  Maintain a common OS and a single point to monitor and manage the network with open APIs.

Share
With a simpler, scalable network to support large resource pools, the next step enables the dynamic sharing of resources for greater agility. This necessitates virtualization at two levels:

• The virtualization of servers, storage and appliances
  The virtualization of the network itself

Virtualization minimizes the need for physical segmentation, allows capacity and bandwidth to be shared efficiently and flexibly for multi-tenancy and high quality of service. VLANs, zones, MPLS and VPLS offer effective ways to virtualize the network within and between enterprise data centers.

Secure
Another challenge involves maintaining trusted environments and scaling security for pooled resources. To complement the simplification and sharing of the cloud-ready data center, the security services also should be consolidated and virtualized. It is vital to secure data and services at rest and in transit using these and other security measures:

• Secure flows into the data center. Authenticate and encrypt connections to network endpoints (SSL) and enterprise devices (IPSec) while reducing device proliferation. It is also essential to prevent denial-of-service attacks and deploy firewalls to guard the edge and perimeter.
• Secure flows within the data center. Segment the network with VLANs, zones, virtual routers and VPNs, and use firewalls to protect application-to-application traffic – between servers, between virtual machines and between pods. Also employ application aware and identity-based security policies.
• Set network-wide policies from a central location to ensure security compliance. Centralized reporting engines provide historical and real-time visibility into applications and data, and enable IT to perform scheduled vulnerability assessments.

Conclusion
By rethinking traditional legacy approaches and preparing for the advent of cloud computing, it is possible for IT organizations to build data center networks that offer greater economies of scale, improved application service levels, simpler management and lower costs. Simplifying, sharing and securing the network are critical to achieving success in building-out cloud-ready data centers. As Moore’s Law ensures that technological advances continue to make cloud-ready data center networks a reality, IT organizations can take decisive steps today that drive businesses closer to the promise of tomorrow.

Elisabeth Stahl is the Chief Technical Strategist, Performance Marketing for IBM Systems and Technology Group.

Anyone who took Psychology 101 in school remembers Maslow’s hierarchy. In this groundbreaking 1943 paper, Abraham Maslow outlined a pyramid to demonstrate the five distinct levels of human “need.” His pyramid showed basic, physiological needs at the bottom, more sophisticated needs at the top, all leading to the ultimate, final phase characterized by a profound level of “self-actualization” of identity and purpose.

However, this theory assumes that only personal growth can be achieved by moving through the five levels. In an interesting twist, we can actually apply Maslow’s hierarchy to data center energy efficiency, allowing us to ultimately realize the maximum potential for our IT organizations.

ELISABETH STAHL

The world has grown passionately interested in energy efficiency within the data center in the last several years. As energy prices climb and organizations outgrow their power and cooling limits, it becomes imperative for data center managers to address IT energy efficiency through green initiatives. Many of us have become intimately familiar with recommendations for improving the efficiency of our data centers. Create those hot and cold aisles, use those pillows and baffles, update those cables and that lighting, consolidate and virtualize, and maybe try some innovative water cooling technology.

So what is the hierarchy for IT energy efficiency and how can we realize the full potential? Let’s outline it step by step:

• Level One: The lowest level of this hierarchy is when energy is still seen as a basic commodity; it has no influence on data center choices. The infrastructure is not monitored and many hot spots exist on the data center floor;
• Level Two: The next level assumes that some thermal monitoring is performed. Some simple decisions have been made to help the infrastructure such as straightforward consolidations and elementary server virtualization;
• Level Three: In this stage, organizations have implemented tools to start actively monitoring IT and non-IT assets such as air conditioners.
• Level Four: Next, we focus on more significant optimization including monitoring metrics such as the power usage effectiveness (PUE), more sophisticated virtualizations using storage and the network, and even potentially employing free cooling which can save thousands of dollars in cooling costs while simultaneously cutting back on greenhouse gas emissions.
• Level Five: Finally, the highest level, the “self-actualization” of data center energy efficiency, can be reached. Here we have the ultimate cooling and powering infrastructure. We see exploitation of the virtualized environment with significant workload management capabilities. This level is most notable for introducing the data center finally as an actual Energy Producer.

How cool is that? We can effectively take the heat we don’t want in the data center and basically reuse it where we need it while saving energy and lowering emissions.

Companies around the world are already implementing this innovative heat reuse approach, sometimes referred to as “district heating,” in a concentrated effort to reach their full potential as an energy producer. For example, by working with IBM, the Swiss Federal Institute of Technology Zurich is building a first-of-a-kind water-cooled supercomputer dubbed Aquasar that will directly repurpose excess heat for the university buildings. The system, which also features a water-cooling system, is expected to cut energy consumption by 40% and carbon-dioxide emissions by up to 85%, resulting in dual IT savings.

Through adopting this final level of the IT energy efficiency hierarchy, we can build a scalable, flexible, and green data center that is dynamic in its infrastructure. Through this “self-actualization” we can potentially save on energy costs; as a producer we might also even be able to make money as well.

NYSE Euronext says it has already pre-sold more than 20,000 square feet of colocation space in its new data center in northern New Jersey, reflecting strong interest in the exchange’s expansion into the data center services arena. The new facility, which opens next year, is the engine driving NYSE Euronext’s transformation into a technology platform for high-speed trading.

“We really see our data centers as the future of our market,” said Stanley Young, CEO of NYSE Technologies and co-global CIO of NYSE Euronext (NYX). “To show how vital this is, we have pre-sold space in that data center a year before our matching engines come online.”

Young discussed the NYSE’s new data centers and the role they play in its business during a panel as it hosted a recent energy efficiency summit with The Green Grid. Young said the 400,000 square foot data center in Mahwah will include 170,000 square feet of raised-floor data center space.

Large Footprint for Colocation
But NYSE Euronext will require just 20 percent of that space for its own infrastructure, Young said. The rest will be available for lease to trading firms seeking high-speed access to the servers – known as “matching engines” – that execute electronic trades.

In the increasingly data-driven environment on Wall Street, access to those servers has enormous value. “For our data center space I can get a multiple of three times what normal data center vendors can get for that space due to the proximity to the matching engines,” said Young. “You can see how valuable that real estate becomes.”

The Data Center as ‘Virtual Marketplace’
That has changed NYSE Euronext’s approach to its business. “We think of our data centers as the exchanges used to think of our trading floors years ago,” said Young. “What we’re seeing with our data centers is that we’re creating that virtual marketplace.

“We’ve actually changed our model,” he continued. “We’re moving from being a place where transactions occur to being what we call a fabric player. We allow industry participants to meet virtually and we get paid for that. That model is now driving all of our thinking.”

This evolution follows decades of market changes that have altered the primacy of the NYSE’s trading floor, once the iconic image of stock trading in the U.S. The emergence of computer-driven trading venues like the NASDAQ market has created a more diverse and competitive trading ecosystem.

Building A Platform Through Acquisitions
These forces have shaped NYSE Euronext’s adoption of technology to extend its reach as the rise of electronic trading shifted a growing percentage of financial trades to loe-latency platforms. In early 2006 the NYSE acquired electronic trading platform Archipelago Holdings to become a public company, and then expanded globally with a deal to buy EuroNext in 2007. 

The NYSE built its technology warchest with acquisitions of trading platform management specialists TransactTools (2006) and Wombat Financial (2008). It is currently in the process of consolidating these tools into a single Universal Trading Platform for the exchange and its partners.

NYSE Euronext sees this infrastructure – including the data center, network fabric and trading platform -as  its competitive edge in the new Wall Street. 

“In our business model we get paid by the transaction,” Young said. “(The number of) trades executed is a big revenue driver. If our market share is under pressure, being able to extend our platform becomes an important part of replacing our revenue from lost transactions.”

The Primacy of Power
As the activity shifts from the exchange post to the matching engine, those transactions are viewed in terms that matter most in the data center – the amount of power consumed.

“Our real business is power consumption and capacity of compute,” said Young. “That is our bread and butter. We sell space in our data centers by the kilowatt. We meter people’s cabinets. The more (trading) they do in those cabinets and the hotter they run, the more we earn. The cost of power is getting down to where people are making trading decisions based on it.”

That trend drove NYSE Euronext’s decision to get into the data center business, building its own facilities in northern New Jersey and London to anchor a next-generation trading operation. “We were running out of power, and had to look at our data centers, our trading floors for the future,” said Young. “We had to make some strategic decisions to build new data centers. It was critically important.”

Building From Scratch
At the time, NYSE Euronext operated out of data centers it leased from third parties. “When we looked around, there was nothing available that met the needs of our markets and business at all, so we decided to build from scratch,” said Young. “That gave us the opportunity to look at every single piece of green technology that was available in order to build these data centers as efficiently as we could.”

Young says billions of transactions every day will flow through the New Jersey facility, known internally as a “liquidity hub” rather than a data center. “You can understand why we build these data centers to 2N+1,” he said. “Everything is double backed up, at least.”

The facility will be able to support power densities of up to 14 kilowatts per cabinet. The company is using a modular design so it can deploy new space as needed.

The NYSE is focused on managing its power, but some popular efficiency measures are non-starters for the NYSE, including virtualization. “We can’t virtualize our trading engines because they’re running full blast all the time,” said Young. “What we’re starting to look into is putting shared memory access onto a matching engine.”

Looking at RDMA as Accelerator
NYSE has also worked with Cisco Systems on an Ethernet-based trading solution using Remote Direct Memory Access (RDMA) accelerators to reduce latency between compute nodes. RDMA allows data to move directly from the memory of one computer into that of another without involving either one’s operating system. Young says this technology  could result in latency of 10 to 15 microseconds when used over 100 gigabit Ethernet connections.

“Our world is a world where microseconds count,” said Young. “My users measure my abilty to serve them in tens of microseconds, and if they had the technology they would get down to nanoseconds.”

Power, cooling and space challenges are the norm for most data centers today. These challenges are a direct result of infrastructure sprawl and disparate technologies caused by cabling, adaptors and switch ports for networking and storage. While server virtualization has begun to address part of the issue, many problems remain and new challenges emerge. This webcast look as ways to solve some of these data center challenges using Fibre Channel over Ethernet.

The main application of Fibre Channel over Ethernet (FCoE) is in data center storage area networks (SANs). FCoE has particular application in data centers due to the cabling reduction it makes possible, as well as in server virtualization applications, which often require many physical I/O connections per server.

With FCoE, network (IP) and storage (SAN) data traffic can be consolidated using a single network switch. This consolidation can:

• reduce the number of network interface cards required to connect to disparate storage and IP networks;
• reduce the number of cables and switches;
• reduce power and cooling costs

Fibre Channel over Ethernet provides a homogeneous I/O such that all servers have access to both the Ethernet as well as Fibre Channel environments. This is key as workloads become more mobile and dynamic across the Data Center. Providing this incremental set of capabilities while optimizing the overall cable count, adaptors, switch ports, heat dissipation and power draw proves to be more and more compelling as servers, storage, and cables continue their otherwise unabated sprawl.

Many solutions are available today and IT organizations are realizing the benefits and efficiencies of products from Cisco, NetApp, and Panduit. This webcast will cover today’s challenges in the Data Center, perspectives on how to address them, and specific methods and products to mitigate infrastructure sprawl.

Today, policy and business leaders are reaching a consensus that industry must address rising greenhouse gas (GHG) emissions, particularly in the data center. Leading enterprises are now turning to the practical challenge of determining how, how much, and at what cost to reduce emissions. In a recent white paper from IDC many companies are learning that their data center offers a means to both abate GHG and reduce costs with the right incremental capital investments.

The process of improving information technology and data center efficiency not only reduces GHG emissions but also reduces cost for the enterprise. This means that the savings or business value derived from improvements far outstrips the incremental capital costs of “greening” the datacenter. Green IT means business improvement. Firms that rank highest among the “Global 100 Most Sustainable Corporations in the World,” such as Amazon, Toyota, and Nike, have realized that focusing on limiting energy calories in the datacenter and elsewhere pays profitability dividends on the financial side. IDC research indicates that companies reducing their metric tons of carbon per datacenter workload by a factor of 55% also incurred 35% less cost per user session on a server.

That would be the new Virtual Private Cloud (VPC) by Amazon.

I am a big proponent of the public cloud but I am a bigger proponent of giving what the customers really want. Amazon had resisted offering a private cloud but they finally gave in and offered a private cloud or at least this is what they want the customers to believe. The bloggers are already questioning whether VPC is a true private cloud. Regardless of the arguments whether the VPC is really a “virtual” private cloud or a “virtually” private cloud, I believe, this placebo cloud is likely to help the customers overcome the cloud computing adoption barriers:

Security: The placebo cloud would alleviate the perceived risk of adopting the cloud computing. The perceived risk is based on the customers’ past experiences. The customers believe that anything that they can connect using VPN must be safe even if they are tunneling into a set of shared resources. The customers will get an environment what they believe is safe and secure to deploy and consume the applications.

Ownership: The VPC does not let the customers own the computing but still provides a sense of ownership. If Amazon’s marketing engine does a good job the customers would be less wary about the lack of ownership.

Virtualization: The customers are not necessarily clear about the real differences between virtualization and the cloud and they necessarily don’t care as long as their business goals are realized. The VPC would allow the customers to work with the existing technology stack that they already understand such as VPN and network-virtualization. The VPC would also empower the partners to help the customers build the bridge from their on-premise systems to the cloud to create a hybrid virtualization environment that spans across various resources.

Even if I personally favor the public cloud I do want to see the customers buy into the cloud computing and later make a decision whether they should move to the public cloud to leverage the cloud in its true sense.

A recent cloud computing report from McKinsey stirred quite a controversy. TechCrunch called the report partly cloudy. Google responded to the report with the great details on why cloud is relevant. I appreciate the efforts that McKinsey put into this report. However I believe that they took a very narrow approach in their scope and analysis. An interaction designer, Chris Horn, from MAYA Design sent me a paper, The Wrong Cloud, which argues that the cloud computing is essentially an old wine in a new bottle and the big companies are fueling the hype.

I appreciate that there are people out there who question the validity and relevance of cloud computing. This puts an extra onus on the shoulders of the cloud computing companies and others to make their message crisper and communicate the real values that they provide. I was recently invited at the Under The Radar conference where many early stage cloud computing start-ups presented. The place was packed with the venture capitalists closely watching the companies and taking notes. It did feel like 1999 all over again! I hope that we don’t fuel the hype and deliver the clear message on how cloud computing is different and what value it brings in. Here are my arguments on why cloud is not just a fad:

Utility style cheap, abundant, and purpose-agnostic computing was never accessible before: There are plenty of case studies about near zero adoption barrier for Amazon EC2 that allowed people to access the purpose-agnostic computing capabilities of the cloud computing at the scale that had never been technologically and economically feasible before. I particularly like the case study of Washington Post where they used Amazon EC2 to convert 17,481 pages of non-searchable PDF to searchable text by launching 200 instances for less than $150 in under nine hours. We did have massive parallel processing capabilities available to us such as grid computing and clusters but they were purpose-specific, expensive, and not easy to set up and access.

Peer-to-peer and cloud computing are not alternatives at the same level: The MAYA paper argues that the cloud computing is similar to P2P. I believe these two are complementing technology. The P2P solves the last mile problem of client-side computing where as the cloud computing is a collection of server-side technology and frameworks that has centralized computing characteristics. BitTorrent is a great example of effectively using P2P for distribution purposes since the distribution problem is fundamentally a decentralized one that could leverage the bandwidth and computing of the personal computers. However I do see potential in effectively combining both the approaches to design an end-to-end solution for certain kinds of problems e.g. use CDN on the cloud with P2P streaming to broadcast live events.

Virtualization and cloud computing are not the same: McKinsey’s report on cloud computing recommends that organizations can get the most out of virtualizing their data centers against adopting the true cloud computing. I am a big fan of virtualization but it does not replace the cloud computing and does not yield the same benefits. Eucalyptus, an emerging cloud computing start-up, has detailed analysis on how cloud computing is different than virtualization.
