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.
The Nexus 2348TQ is a compact, 1RU Fabric Extender that offers:
– 48 x 10G BASE-T host port interfaces
– 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.
I invite you to learn more about the Nexus 2348TQ and other Nexus 2300s at www.cisco.com/go/nexus2000.

It’s an exciting time in to be in our industry, especially as we witness how technology continues to reshape how we connect and communicate through a myriad of applications and devices not only within our own companies, but also with our customers and partners.
At the epicenter of this technological transformation, we continue to find that the network is what ultimately enables these applications and their users to connect. We also quickly find that if this same network is not ready to deal with the ever increasing influx of devices, new applications with varying traffic patterns, and 24 x 7 access from pretty much anywhere, it can quickly turn into an IT departments nightmare.
It is exactly to deal with these new types of requirements that the award-winning Nexus 9000 Series (made up of both the Nexus 9500 and Nexus 9300 portfolios) was introduced into the market almost 11 months ago. Now, over 600 customers have purchased this new switching family and are experiencing the positive impact that having a high performing, scalable, programmable, and resilient data center network has on application performance and overall user quality of experience in both traditional and Application Centric Infrastructure (ACI) architectures.
Today we are happy to announce the addition of three new switches into the Nexus 9300 Series as well as a 6-port 40Gbps module to deliver more flexibility and form factor options to meet different architectural needs. The new products are:
- Cisco Nexus 9372TX: 1-rack-unit switch supporting 1.44 Tbps of bandwidth across 48 fixed 1/10-Gbps BASE-T ports and 6 fixed 40-Gbps QSFP+ ports
- Cisco Nexus 9372PX: 1-rack-unit switch supporting 1.44 Tbps of bandwidth across 48 fixed 1/10-Gbps SFP+ ports and 6 fixed 40-Gbps QSFP+ ports
- Cisco Nexus 9332PQ: 1-rack-unit switch supporting 2.56 Tbps of bandwidth across 32 x 40Gbps QSFP+ ports
- 6-port 40 Gigabit Ethernet Module for the Nexus 93128TX, 9396TX , and 9396PX for connectivity options to meet your needs
These new switches deliver high performance, additional buffers, as well as support for VXLAN routing in a compact form factor. In addition to this, support for the Cisco Nexus 2000 Fabric Extenders has also been added to the Nexus 9300 portfolio. So if you already had Fabric Extenders in your data center or are looking for a scalable and operationally simplified architecture – you can now have the best of both worlds.
But it doesn’t end there – in case you missed it, Cisco recently announced the availability of the Application Policy Infrastructure Controller (APIC) making the creation of a more simplified, robust, application-centric infrastructure a reality with the Nexus 9000 Series as the network foundation. You can read more about it here – in Craig Huitema’s blog, which outlines not only new products on the nexus 9000 series including 100Gbps on the Nexus 9500, but also how we have simplified the introduction of the Nexus 9000 and ACI into data centers through different ACI starter kits and bundles. In addition, for those of you that want to deploy the Nexus 7000 in combination with the Nexus 9300s, new bundles that bring together the Nexus 7000 and Nexus 9300 are also available.
As you can see, we continue to deliver the products and architectural options that will allow data centers of all sizes to address increasing and changing application requirements. Between the Nexus 9300 and Nexus 9500 portfolios and their ability to be deployed into 3-tier, spine/leaf, or ACI architectures, customers can benefit from more connectivity options and a diverse set of form factors to meet varying data center needs.

Complexity and Cost Comparison: Cisco UCS vs. IBM Flex System is report recently published by Principled Technologies.
They evaluated both the technologies and costs of each solution and found a UCS solution is both less expensive to deploy and less complex to manage than an IBM Flex System.
Off all the ways Principled Technologies shows how UCS is a superior solution, I wanted to touch on just one: highly available and scalable management. A UCS management domain consists of a pair of Fabric Interconnects and supports up to 160 blade and/or rack servers. In contrast, IBM is limited to 54 blade servers plus a non-redundant Flex System Manager node. Quoting from the paper:
Because IBM Flex System Manager nodes do not failover automatically like the Cisco UCS solution, administrators must manually connect to a backup node and bring it online. Each target system has an OS agent that remains registered to the original FSM node and does not recognize the new FSM. Admins must manually unregister each of these agents from the failed node and then register the new FSM node. [page 7]
Read the full report to learn the many additional ways which UCS is shown to be superior solution and why Cisco has leapt ahead of IBM and is now the #2 blade server vendor worldwide1
Would like to learn more about how Cisco is changing the economics of the datacenter, I would encourage you to review this presentation on SlideShare or my previous series of blog posts, Yes, Cisco UCS servers are that good.

Cloud computing is part of the journey to deliver IT as a Service which enables IT to change from a cost center to a business strategic partner. Forrester Research recently published a report that concluded, “Cloud computing is ready for the enterprise… but many enterprises aren’t ready for the cloud.”1 Yet Cloud deployments are happening – and I mean all types of Clouds – Private, Public and Hybrid. In other words, we have entered the World of Many Clouds.
Network touches everything and is a key building block for agile and scalable virtualized and Cloud-based data centers. Yesterday, I have introduced our new Nexus 6000 series and new 40 GE extensions to Nexus 5500 and 2000 Series. Today, I would like to introduce the very first services module for the Nexus 7000 Series.
