Algo Boost Series: Part 2 Customer Perspective on Cisco Nexus 3548

On October 5th I posted part 1 of the Algo Boost series with a fantastic discussion around the latency innovations on the Nexus 3548. Today, we announced that these units are now shipping to customers and the much anticipated wait is over to get this game changing technology! This is perfect timing as I introduce part 2 of the series with Errol Roberts, Distinguished System Engineer for the top Data Center accounts, to bring a customer perspective to the ultra-low latency Nexus 3548 in a High Performance Trading fabric.

[GD]  I know that you spend a lot of your time talking with customers. What are our Financial Services customers telling you about their environments and requirements?

[ER] When meeting with these customers, I like to ask a single question -- “What value can an infrastructure company provide to high-performance trading workloads”.  Key points relating to the switching are captured by the following:

  • First, customers ask for a network solution and architecture that provides them with the fastest end-to-end functionality. Providing the “Lowest latency possible” is one vector, another vector being a rich “feature-set” answering the different architecture and network requirements end-to-end. Naturally there is a need for speed while at the same time providing the features within the same device. For example in collocated High Frequency Trading environments; the lowest latency being key; it’s not the only factor; support for the routing protocol such as BGP, multicast with PIM Sparse mode, ultra low latency SPAN at linerate with multiple ports; this is achieved with the technology called Warp SPAN.
  • Next, “Handle microbursts”. Volatility is correlated. When you are running cross-asset class, cross-liquidity venue strategies, there is often short-lived congestion that increases latency. These volatile periods are often the most opportunity rich.
  • Also, “Unique features”.  They want features like Network Address Translation to meet their business needs. You don’t want these features to add latency. In fact you don’t want to have any of the L4 or services applied on the network to add latency.
  • Next, “Flexibility and Programmability”. They want to control their traffic flow, mirror relevant traffic, have fine-grained flexibility and also have reactivity on events. Python scripting language is a good example of automation. With Python script, you can have the switch react on different environmental changes such as a sanity check when the device comes online as well as for example triggering emails when the burst happening at the buffer level exceed for example 10 nanoseconds.
  • In addition, facilitate “Precision Time”. You cannot control what you cannot measure. Without precision time, you invest in an infrastructure and just hope you get optimal performance. With precision time protocol you can keep all of your servers and network elements highly synchronized at the nanosecond level.  You can even measure the accuracy of the tool through a 1 pulse per second output port. Also, the Nexus 3548 can timestamp traffic with IEEE 1588, which allows analyzers to replay events.

Algo Boost Series: Part 1 Nexus 3548 Latency Innovations

The Nexus 3548 with Algo Boost was announced last week and received a lot of positive buzz around this game changing innovation. To follow up on Berna Devrim’s Introduction Blog, I am introducing a multipart series that goes into more specifics by Cisco experts. As part 1 of the series, I recently had the opportunity to have a chat with Will Ochandarena about the latency enhancements. Will is a Senior Product Manager in the Server Access and Virtualization Business Unit.  In this role, he is responsible for the Nexus 3548 switch, and Cisco’s low latency switching strategy.

GD: The Cisco Nexus 3548 switch with Algo Boost was announced on September 19th and received a lot of positive attention. Can you elaborate a little more on the latency that this switch can achieve? How does this benefit our financial customers?

<WO>: The custom switching ASIC in the Nexus 3548, codenamed Monticello, sets a new bar for switching latency.  Our engineers worked tirelessly to eliminate unnecessary nanoseconds from the forwarding path, tweaking it down to as low as 190 nanoseconds (ns).  Best of all,  this latency is achieved even when we are doing full layer-2 and layer-3 switching, with features such as Network Address Translation (NAT) enabled.   We actually went as far as to offer a few different switching modes, each with different latency and forwarding characteristics, in order to give our customers the most flexibility in their deployments.

In terms of the impact on our end customers, we consistently hear from companies in the financial community that switch latency has a direct impact on the profitability of their business. Trading firms -- as well as the exchanges and other participants -- gain significant business advantage if the supporting infrastructure enables them to acquire data and execute trades nanoseconds faster than the competition.

Cisco Unified Data Center IQ Contest – Time to Participate !

September 28, 2012 at 7:19 am PST

..AND WIN !!

Think you know Cisco’s Unified Data Center? Like to friendly  compete with others ?  Well , well ! It’s about time to prove it!   There are at least two ways to do that: the serious and the fun.

The Serious Way: You deploy an Unified Data Center at Work - Can it be risky? -- Not really ..but check out this video anyway:

Disclosure : The numbers displayed in this video are extracted from a real case study

The Fun Way:  Participate to the Unified IQ Contest!

 

Starting on October 1st, we give you the opportunity  to test your knowledge .
A fun and easy way to play and compete  with an immediate reward.  During 6 weeks , we will propose every week a set of questions with multiple choices  created by our genius and facetious bloggers.  We will cover topics such as Unified Computing Systems, Unified Fabric, Unified Management, Desktop Virtualization, Cloud,  Open Network Environment. You got the picture! The whole Cisco  Unified Data Center portfolio !

Introducing Cisco Algo Boost and Nexus 3548 – Breaking 200 ns Latency Barrier!

… While Delivering Superior Fabric Visibility!

Today, at the High Performance Computing for Wall Street event, we announced Cisco Algorithm Boost or Algo Boost technology, a groundbreaking networking innovation with numerous patents pending, that offers the highest speed, visibility and monitoring capabilities in the networking industry.  A true game changer delivering competitive advantage to our customers!

Ideal for high performance trading, big data and high performance computing environments, this new technology offers network access performance as low as 190 nanoseconds, more than 60% faster than other full featured Ethernet switches.  When your business success is determined by nanoseconds, this is a huge gain!

The first switch to integrate the Cisco Algo Boost technology is the new Cisco Nexus 3548 full-featured switch which extends Cisco’s leadership in networking by pairing performance and low latency with innovations in visibility, automation, and time synchronization.  And it is tightly integrated with the rich feature set of our Nexus Operating System, a proven operating system used in many of the world’s leading data centers, creating a truly differentiated offering.

Unified Fabric for a Backup Server

September 10, 2012 at 12:32 pm PST

Outside of that large, black, monolithic machine in the middle of the datacenter referred to as the mainframe, there aren’t that many servers that require as many network and storage connections as the backup server.  It’s not really sexy, it’s not computing Pi, generally doesn’t run a hypervisor and is bought with one goal in mind, move data. Not just some data, but a lot.  These machines often move all of the data in your datacenter off of disk and onto tape, either real or virtual.  In many datacenters, these backup servers are sometimes the only non-x86 platforms left due to their ability to contain high numbers of HBAs for SAN connectivity and NICs for network connectivity.   They’re like the tractors of the datacenter.
