What is the new Nexus 5600?
We at Cisco are really excited to introduce the new Cisco Nexus 5600 platform! It is the third generation of industry’s leading Data Center Server-Access Nexus 5000 series of switches. Cisco Nexus 5600 is the successor of industry’s most widely adopted Cisco Nexus 5500 series switches (with over 20,000 customers and 25 million ports shipped) that maintain all the existing Nexus 5500 features such as LAN/SAN convergence, Fabric Extenders (FEX) and Fabric Path.
The new Nexus 5600 was unveiled at CiscoLive Milan in January 2014 with quite a bit of interest
Nuts and Bolts
We are introducing 2 models under the 5600 platform:
Cisco Nexus 5672UP – A 1 RU 10/40G Ethernet switch offering wire-speed performance for up to 48 10G Ethernet ports (16 of which are Unified Ports) and 6 true 40G ports.
Cisco Nexus 56128P – A 2 RU 10/40G Ethernet switch offering wire-speed performance for up to 96 10G Ethernet ports (48 of which are Unified Ports) and 8 true 40G ports..
In addition to the existing features of the Nexus 5000, 5600 platform brings new features such as True 40 GE support, VXLAN bridging and routing and Cisco Dynamic Fabric Automation (DFA) innovation. With a latency of about 1 µsec, the 5600 platform is ideal for applications which need low latency. For those of you who need network programmability, the Nexus 5600 supports Cisco OnePK and Openflow.
Why these new features matter
Extensibility with VXLAN support
The Cisco Nexus 5600 with its VXLAN support is very well suited for multi-tenant cloud deployments. In large scale, multi-tenant cloud deployments, there is a need for VMs to migrate across layer-3 boundaries. Traditional VLANs only support about 4000 VLANs which are insufficient in the deployments of thousands of VMs. With the migration need across layer-3 boundaries complexities of layer-3 routers are introduced. To solve the scalability as well as the migration issues VXLAN was developed. For more details on VXLAN, watch the video: http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps9902/vidoe_fundamentals_vxlan.html
Ease of management with Cisco Dynamic Fabric Automation (DFA)
Our customers are also faced with complex, manual network configurations and have a hard time keeping up with application requirements. To solve these challenges, Cisco has developed an architecture called Dynamic Fabric Automation (DFA) which simplifies management and automation – such as automatic device and fabric configuration, automatic VM deployment, migration and seamless integration of bare-metal and virtualized resources in the data center. The Cisco Nexus 5600 platform with DFA implemented in the hardware as well as software is ideal for the multi-tenant and mixed (physical and virtual) cloud infrastructure.

True 40G support
The difference between a 40G and True 40G port is that you can push an entire 40G flow in the True 40G port and in the normal 40G port, the port really is divided into 4 10G ports via Etherchannels, Thus in the True 40G, you get full 40G bandwidth. The Cisco Nexus 5600 platform switches has True 40G ports, which help in servicing the full 40G flows.
The Big Picture
Cisco has one of the most comprehensive portfolios for the Data Center and Cloud Networking and this Nexus 5600 platform is but one of the pieces of this portfolio. You may want to read this excellent blog, which explains Cisco’s Data Center and Cloud Networking portfolio.

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.
