There is no doubt that the word transformation is being used to describe pretty much anything to do with the data center, but in all of this, it’s good to remember that little things can make a BIG difference in making day to day data center operations easier.
With simplicity as one of the key tenants, the Nexus 2300 Series Fabric Extenders continues on the same trajectory as previous Fabric Extenders by delivering a solution that, when coupled with Cisco Nexus parent switches, makes adding performance, scale, and operational simplicity to the network access simple.
Today, we add a new member to this 3rd generation fabric extender family – the Nexus 2348TQ, which together with the Nexus 2348UPQ, offers more connectivity options for data centers of different sizes with varying performance and application needs.
- 6 x 40 Gigabit Ethernet ports for parent switch connectivity
This makes the Nexus 2348TQ an ideal solution for data centers looking to upgrade their server access deployment from 1GBASE-T to 10Gbps speeds and from 10Gbps to 40Gbps connectivity.
As outlined in my previous blog, all members for of the Nexus 2300 Series Fabric Extenders support:
Larger buffers to absorb bursts of traffic for a wide variety of workloads such as multicast feeds, voice traffic, video traffic, and healthcare applications
Unified Ports support enabling a flexible LAN and SAN deployment through support for Ethernet, Fiber Channel and Fiber Channel over Ethernet connectivity
Support for Cisco’s 40G BiDi optics simplifying migration 10 to 40 Gigabit Ethernet speeds while reusing existing 10G cabling
Additional versatile TCAM which can be used for:
Advanced features such as ACL classifications and QOS
Hardware-capable local flow redirect for architectures that require intra-rack traffic to reduce bandwidth
Bringing Together Nexus 2300 Fabric Extenders and Cisco Nexus Parent Switches
The Nexus 2300 Fabric Extenders can be perfectly paired with Nexus 5600 and 6000s as well as Nexus 7000* and 9000* (*future) to provide a network access solution that combines the flexibility and simplified cabling of a top-of-rack (ToR) designs with simplified management and efficient utilization of an end-of-row (EoR) design. This flexible architecture where the parent switch manages all fabric extender configuration lets you deploy and re-deploy fabric extenders throughout your data center with minimal reconfiguration needed, not only helping reduce operational and capital expenditures, but also allowing your data center network to quickly adapt to application, traffic, or business needs.
It may sound strange to hear me say it, but when I wrote the previous blog post about Dynamic FCoE I thought that it may get a little blip of attention and then filed away as a “oh, that is cool” little factoid about Cisco’s storage portfolio. Perhaps I shouldn’t have been so nonchalant, but I confess I was not expecting the number of questions that I (and other speakers at CiscoLive back in May) have been getting about the technology.
Many questions – including some in the comments of the previous blog – have indicated a strong desire to know more, and they have been excellent and well-thought out. I’m going to try to address some of them in a deeper dive blog whenever I can, in the hopes of being able to address some of the concerns and clarify some points.
We’ll start with one of the biggest concerns – sharing the spine layer for logical separation of SAN A/B, and what happens if one of the spine switches (nodes) go offline. Read More »
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.
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.
The next generation Nexus 5600 family offers VXLAN bridging and routing capability, line rate L2/L3, and 40G uplinks, to deliver high performance in a compact form factor for 10G Top of Rack, 1/10G FEX aggregation deployments.
AND THERE HAS BEEN BROAD CUSTOMER ADOPTION ACROSS THE DATA CENTER!
From Nexus 1000V to the Nexus 9000, Cisco’s holistic approach resonates with customers because it provides increased business agility, operational efficiency, and empowers IT to rapidly evolve as business requirements change.
Here are the latest examples of why our customers chose Nexus:
Cisco today introduced Application-Centric Infrastructure as the vision for Next Generation Data Center architecture, built for both today’s physical and virtual workloads as well as tomorrow’s highly dynamic Cloud-based, and performance-intensive big data application environments.

What I would like to share with you is how we are evolving the Cisco Unified Fabric to deliver operational simplicity through superior integration.
Delivering Operational Simplicity through Superior Integration
As organizations accelerate private and public cloud deployments, IT organizations and data center networks must evolve to meet rapidly changing and growing requirements. Virtualized and cloud environments require more agility and simplicity to quickly deploy and migrate virtual machines. IT organizations, on the other hand, are challenged with operational complexity, architectural rigidity and infrastructure inefficiency with manual processes, disjointed provisioning, deficient software overlays, static resource allocations and disruptions when growth is needed.
The good news is that Cisco continues to evolve its Unified Fabric to address these needs. The new Cisco Dynamic Fabric Automation delivers unsurpassed operational simplicities through superior integration. It does this by …. Read More »
