Cisco launched its Nexus® 9500 series of data center modular switches, which Cisco promises offers not only the highest port density of 10/40/100GbE, and the most programmable and fastest packet forwarding modular data center switch in the industry, but the most power efficient too. To verify and measure the power efficiency claim, Cisco engaged the Lippis/Ixia team to test the new Nexus® 9508 modular data center switch for power draw at scale. We found that the Nexus® 9508 sets a new record in data center modular switch power efficiency drawing some 3.85Watts per 10GbE port at a scale of 1,152-10GbE ports populated in a single chassis.

At the Open Networking User Group (ONUG) this past October 29th and 30th, hosted by JPMorgan Chase in New York City and attended by over 500 influential IT and industry business leaders, virtualized networking overlays and the need for high performance plus reliable underlays was top of mind. With 2014 and 2015 being the years of open networking pilots and deployments, respectively, much focus was on high-density 40GbE spine switches from Cisco’s Nexus® 9000 series, Arista’s 7500E and HP’s 11900/12900. At ONUG, IT leaders expressed multiple drivers for high-density 40GbE spine switches, including connecting thousands to hundreds of thousands of servers at 10GbE, support for IP storage and the high-growth of virtual connectivity via network overlays, all over a high-performance and highly reliable underlay. In this Lippis Report Research Note we explore the three reference designs for building 288-40GbE spine switches based upon Broadcom Dune, Broadcom Trident II and the new hybrid, custom plus merchant silicon, with an eye toward reliability and available based upon component count and measured in terms of Mean Time Between Failure.

Cisco recently launched its Nexus® 9500 series of data center switches which Cisco promises offers the highest port density of 10/40GbE and future 100GbE—the most power efficient, the
most programmable and fastest packet forwarding modular data center switch in the industry. To verify these claims, Cisco engaged the Lippis/Ixia team to test the new Nexus® 9508 modular data center switch. We found that the Nexus® 9508 sets new records in data center modular switch performance. In short, it’s the fastest modular switch under the Milky Way.

The definition of Software-Defined Networking being the separation of data and control plane offered little to DevOps professionals or network engineers seeking a programming environment to customize their network and automate opera¬tional tasks. With the introduction of the Nexus® 9000, Cisco is offering the most compre¬hensive set of network programming options that delivers programming tools through an enhanced version of the Nexus Operating System (or NX-OS), which ranges from direct switch programming via its built-in Linux BASH environment, open RESTful APIs with JSON and XML support, direct integration with Python, etc. Most network engineers will opt to enroll in a Linux programming course versus obtaining another CCIE certification after reading this Lippis Report Research Note. In this research note, we review Cisco’s new programming environment detailing its options, use cases and industry impact.
