Mobility and the cloud have changed how we work, transforming pockets of downtime into bursts of productivity, with easy access to our most valued information and people. But this transformation has unleashed havoc. Security practices built on decades-old assumptions of placing controls at key points in the infrastructure won’t work in today’s hyper-connected application and data-centric world.
Mobility and cloud have shifted the power balance from IT to users. Business units and workers are embracing public cloud services for everything from document sharing to payment services. Most CISOs cannot state with confidence that their organization’s information assets are secure.
The industry needs to embrace innovative security and identity architectures so organizations can protect their users’ identities, devices, and data, wherever and whenever they are. Now is the time for InfoSec pros to embrace CHAOS and enable the business to move forward quickly and securely.

Last July, Cisco announced the new Nexus 7700 switches (Nexus 7710 and 7718) as part of the Nexus 7000 Series, offering higher 40G and 100G densities and also delivering front to back airflow in a smaller form factor. Along with the new 7700 chassis, we announced the next generation F-Series modules, the F3 40G and 100G modules. From a feature perspective, the F3 modules combine the feature set of the F2 and M2 modules into a single module, making module selection, switching configuration and spare stocking much simpler.
In late January at Cisco Live Milan, we added to that announcement with the introduction of the Nexus 7706 and a 10G F3 module for the Nexus 7700’s.
The Nexus 7706 offers the performance and features of its bigger brothers the 10 and 18 slot chassis, but in a smaller form factor. The 10 and 18 slot chassis work great for large deployments where densities drive the chassis selection, however, talking with customers who have small/medium sized data centers, it was clear that they want the rich feature set of the Nexus 7700, but didn’t need 768 10G ports or 384 40G port densities in a single switch. Sure it gives them room to grow, but it also takes up real estate in their small data centers.
The small form factor Nexus 7706 with 4 module slots provides the ideal capacity for small/medium deployments. With up to 192 10G ports, 96 40G ports or 48 100G ports, the Nexus 7706 delivers more than enough switching capacity for today’s small data centers with ample growth capacity for future growth. We are also seeing customers leverage the Nexus 7706 for Data Center Interconnect (DCI) deployments, where high densities aren’t generally required. Because of its versatility, we’ve seen significant customer demand for the 7706 since it’s introduction…actually higher than we originally expected.

Read/write symmetry refers to a solid-state system’s ability to execute either a read or a write call or a function with equal levels of priority, importance and delivery—it takes the same amount of time to read as it does to write. Achieving read/write symmetry should be a priority for your business for two reasons: symmetry affects performance and symmetry implies quality.
Writes are important, more important than many realize. A common practice is to look at an application and its IO profile. This is a critical step, but its results are often misinterpreted. The goal is to understand how that application works, how much time does it write, how much time does it read and so on for the entire lifecycle of the data. Some applications spend more time doing one activity versus the other and we often make assumptions regarding the importance of write IOPS if our write activity is less than 50%.
Let’s say I’ve done my IO evaluation and I’ve discovered my application writes 30% of the time and reads 70%. I may think write symmetry with respect to performance does not matter, but that is not actually the case. I have to consider the criticality of that particular write operation.
As a hypothetical IO analysis let’s consider a banking application that produces account activity statements at the end of each month for all customers, which is required by bank regulations. The application is going to go through everybody’s accounts, total them up, summarize them and store that summarized data in the form of the month-end statement. For most of the month the database of record is writing far less of the time than it is reading.
Let’s dig in to the data collection used by the application. If I have 50 million accounts with an average of 25-50 transactions per month, I get 1,250 to 2,500 million transactions created each month. Now consider that if you keep 12 months worth of transactions per year in your current customer data collection, the average of at least the last fiscal years’ transactions could total between 30 to 60 trillion records. The program to calculate month-end statements will be doing a lot of reading. It will focus on the current month’s data, which is 1/12th of 30-60 trillion records. But, more importantly, it will be doing extremely critical writes in an extremely short period of time.
Read/write symmetry is important to look at beyond just making sure applications can perform write operations quickly. Flash vendors use a block translation layer (BTL) to manipulate and improve the write performance of flash. This BTL does much more than increase the speed at which flash writes. But if a system has read numbers that far exceed the write numbers and one sees a dramatic degradation in write performance with that system, then you can safely infer that the software layer is carrying the write asymmetry back out to the operating system of the host application and the application itself. This ratio of write to read performance should be looked at closely when evaluating systems regardless of the IO Profile of an individual application.
Write performance isn’t only important to applications, it’s essential to the entire business. Applications cannot read anything that hasn’t first been written and they can only go as fast as their slowest write, which means the entire business may be at the mercy of its solid-state system as it waits on writes.

Later this month I’ll be taking part in a webcast dedicated to helping viewers Uncover the Business Impact of Application Acceleration with Solid-State Systems. I think the most important thing for business executives to understand is that application acceleration goes beyond enabling workloads to run faster. It’s also about reducing the time that it takes to make resources available so that you can accelerate applications. This concept is equally important.
Now we have an end-to-end performance story. Something that used to take weeks can now potentially be done in a day. The notion around spending time troubleshooting becomes dramatically reduced. The ability to just simply assign resources or quickly deploy assets and bring them into the environment and immediately use them becomes very, very easy. Where in the past there was a lot of thought and planning that had to go into it, “What am I buying, and how will it be configured, and how will it potentially be used?”
Now I have this wonderful environment called UCS. I have high-performance computing. I have flash memory. I have the ability to organize the resources through the UCS management technology, and I can focus on speeding up my business, my entire business. I can focus on bringing my new ideas online while taking full advantage of the applications that I have in place today, and watching each and every one of them run faster with minimal, if any, changes.
We’re really going to help propel customers into the future. A future that is about the Internet of Everything. A future that is about consistently high performance, and a future that is about getting things done much, much faster tomorrow than we do today. That’s part of what this webcast will articulate.
