No Latency Load Balancer in Data Centers

Cisco Intelligent Traffic Director (ITD) is a zero latency multi-terabit layer 4 load-balancer available on 5k/6k/7k/9k. It has support for traffic steering and clustering solution on the Nexus  series of switches.

ITD allows customers to deploy servers and appliances from any vendor with no network or topology changes. With a few simple configuration steps on a Cisco Nexus  switches, customers can create an appliance or server cluster and deploy multiple devices to scale service capacity with ease. The servers or appliances do not have to be directly connected to the Cisco Nexus switch. ITD takes load balancing decision in a single clock cycle of the switching hardware, Hence avoiding latency altogether.

ITD supports IP-stickiness, resiliency, NAT (EFT), VIP, health monitoring, sophisticated failure handling policies, N+M redundancy, IPv4, IPv6, VRF, weighted load-balancing, bi-directional flow-coherency, and IPSLA probes including DNS. There is no service module or external appliance needed.

ITD provides order of magnitude CAPEX and OPEX savings for the customers. ITD is available on Nexus 7000/7700 series in NX-OS 6.2(10) or later. It is available for demo/EFT on Nexus 5k/6k/9k.  ITD is much superior than legacy solutions like PBR, WCCP, ECMP, port-channel, layer-4 load-balancer appliances.

VoLTE Policy Management to Improve Subscriber Experience and Lower Cost of Growth

Written By Alfonso San Jose, Sales Consulting Systems Engineer

Alfonsov2

We have been hearing from our Service Provider customers like you about their interest in Voice over Long Term Evolution (VoLTE), and for good reason.  Offering VoLTE affects profitability in two ways. One is by creating a great voice experience that helps to attract and retain subscribers. VoLTE provides guaranteed quality of service and fast call-setup time. At the same time, VoLTE can lower network costs. However, VoLTE creates new demands on the network that requires a policy management solution to address. VoLTE changes the game for policy management because it imposes much heavier demands than 4G data services. The policy management solution needs to meet the following four requirements: Read More »

Summary: Decoding UCS Invicta Part 1

Storage 101

Less than a year ago, October 29th 2013, Cisco acquired Whiptail {http://newsroom.cisco.com/release/1279074}, a high performance scalable solid-state memory system. Shortly after its acquisition, the product lines were renamed UCS Invicta.

The idea behind UCS Invicta and its market positioning is application acceleration. This is not to be considered a traditional storage but instead a solution to enhance application performance. In fact, Cisco has made it quite clear that they have no plan to target the traditional storage market:

“This acquisition is really about the server market. It’s a significant opportunity, but distinct from the portion of the market served by traditional stand-alone storage systems. As a result, our continued engagements with NetApp on FlexPod, EMC on VSPEX and VCE on Vblock will not change. We have no current plans to expand into the broad based, traditional storage market.”

Now, just as it happened in 1998 when Cisco got into the VoIP market, and then in 2009 when it got into the server market, we need to learn a new lingo and we need to understand the pains of that market.

In this blog series, I’ll be covering some of the lingo, highlighting some of the pains the users have and describing what UCS Invicta brings to the table. Learn more here.

Cisco’s 802.11ac Portfolio Expands with the New Cisco Aironet 2700 AP

As a Product Manager there is some anxiety but more of an excitement around introducing a platform to the market. Today I am proud to be part of Cisco team that is  bringing to market the Cisco Aironet 2700 Series Access Point.  What it offers is a tremendous amount of power at a very attractive price point.  

2700

We all know Wi-Fi is here to stay and is expanding all around us rapidly. That need for speed is exciting.  But what does that mean? Not everyone feels comfortable being on the cutting edge. Many of our customers are not as concerned about chasing the future and have more limited budgets that they hesitate to put down for the best AP knowing there are lower priced options.  At the same time, everyone is aware technology moves ahead with or without you, so they don’t want to give up lot of the new capabilities by going totally to the other extreme of not upgrading at all.  What they want is something that’s going to last for a while that gives them the advantages available today, but not have to invest a lot to get it. I equate this to buying something like a car.  A year ago when I was in the market to buy a new car I didn’t want to sacrifice whole lot of options but if there was one or two options that I could give up in order to save a bit of money, I was okay with that.

This is similar to what Cisco is offering with Aironet 2700 Series.  Customers have to choose something that they can utilize in their network that is better than any of the competitive solutions out there, truly built-for-purpose, sleek design on the outside yet tough on the inside and very powerful.
