#EngineersUnplugged S5|Ep2: ACI and Traditional Networking

March 12, 2014 at 10:53 am PST

This is an amazing episode of Engineers Unplugged, where two technologists from the community, Hal Rottenberg (@halr9000) and Colin Lynch (@ucsguru) discuss how ACI disrupts traditional networking thinking while leveraging current networking skills. It’s a great tutorial for anyone looking to understand what application centric infrastructure really means.

Will network engineers all become programmers?

Watch and see:

With Cisco Cloud Management, FASTWEB Delivers New Value-Added Cloud Services

Imagine that you head the leading telecommunications provider in Italy and you are watching traditional service and revenue streams struggle under intense competitive pressure. Customer retention is a major issue because the types of services required by your residential and business clients are changing. Clearly, you need to retain customers and do so by offering new services. It is a generally known business fact that often it is more cost effective to invest in retaining customers than trying to get new ones in such competitive industries.

So, how would you do it?

FASTWEB, a Swisscom company, asked Cisco exactly that question. FASTWEB’s analysis indicated that offering cloud-based service delivery would be an excellent opportunity to retain existing business while capturing new revenue streams from Italian businesses looking for new IT solutions. But FASTWEB struggled with execution due to insufficient resources to develop and deliver these new services.

So, FASTWEB adopted Cisco’s Unified Data Center architecture which includes Cisco UCS Blade Servers and Intelligent Automation for Cloud (IAC). Cisco UCS servers were selected for performance, reliability, and the ability to integrate smoothly with other heterogeneous elements in their solution stack. They thoroughly analyzed cloud management solutions, and Cisco IAC scored the highest in their evaluation for:

• Openness and flexibility
• Ease of use by users and administrators
• Single management console access to the entire cloud service lifecycle
• Ability to build services without deep technical skills

FASTWEB

Teaming with Cisco Services, FASTWEB implemented cloud service delivery across six distinct use cases. Because of UCS they did so with minimum server hardware, gaining a complete cloud infrastructure that consumes only a few racks. With this Cisco Unified Data Center strategy and solution, FASTWEB estimates their customers can save around 50 percent over three years utilizing FASTWEB services compared to on-premises infrastructure.

What’s more FASTWEB relies on Cisco IAC to offer customers a portal that is intuitive with fast delivery thanks to strong automation and orchestration of all cloud elements, including network. None of their competitors in the Italian marketplace has an offering equal to this unified solution from Cisco.

Now FASTWEB’s cloud services are growing smoothly thanks to technology that scales as quickly as their business does. FASTWEB plans to expand its use of Cisco IAC to offer new services as such PaaS and SaaS for their customers.

Improve Cloud Traffic Visibility with the New Cisco Prime Virtual NAM

March 7, 2014 at 10:22 am PST

Earlier this year Cisco announced the Cisco Prime Virtual Network Analysis Module (vNAM), an integral component of the Cisco Cloud Network Services portfolio. While a virtual NAM has been available on the Nexus 1100 Cloud Services Platform (a UCS appliance for virtual services), it has not been available in a generic VM form factor, which now provides greater deployment flexibility for NAM customers, as they look to monitor application and network performance in their virtual data centers. The result is greater visibility at more points in the network.

Cisco Prime vNAM combines application-awareness with the ability to look deeper into various network overlays, such as VXLAN, LISP, and CAPWAP, to deliver rich analytics that help assure services levels, accelerate operational decisions, and increase business agility. Its versatility permits it to be used to:

  • Monitor workloads in multi-tenant cloud deployments
  • Analyze network usage by application, host or virtual machine (VM) to identify unusual traffic patterns or bottlenecks that may affect performance and availability
  • Troubleshoot performance problems consistently across physical and virtual environments
  • Take advantage of an integrated web-based interface to remotely manage a site
  • Validate infrastructure updates such as WAN optimization, Cisco TrustSec, and quality-of-service policy changes

Prime vNAM can be deployed in the cloud to monitor hosted workloads, at remote sites to monitor the end-user experience, or almost anywhere in the network to eliminate blind spots.

Things You Can Do in 16 Minutes: Pushing the VDI Performance Envelope with Cisco UCS, VMware Horizon View and EMC VSPEX

So what exactly can you do in 16 minutes?  Well, you can:

  • Download and install your preferred tax prep software, because (if you’re in the US or Canada) April is coming
  • Enjoy your 15 minutes of fame, then reminisce and/or lament about it for exactly 1 minute.
  • Save 15% on your car insurance (you can supposedly get this done in 15 vs. 16 min.)
  • Do some really unsavory things not suitable for mentioning on a nice blog post like this one.

Don’t care about any of those things?  Neither do I.  Let me come back to this in a moment…

If you’re familiar with our architecture portfolio for desktop virtualization, you may be aware that we’re continuing to invest in VSPEX-based reference architectures for Cisco Desktop Virtualization.  This week, we just announced the latest addition to the Cisco Validated Design (CVD) portfolio – our solution for VMware Horizon View 5.3 with Cisco UCS and EMC VSPEX available here.

If you’re not already familiar with them, CVD’s provide prescriptive design guidance around how to build solutions with specific outcomes (performance) as documented through a testing/documentation discipline that Cisco’s been doing for years.  You’ll find our repository of desktop virtualization CVD’s here.

So now let’s talk about the CVD itself.  Our principal author is Ramesh Guduru – he’s a Virtualization Systems Engineer in Cisco’s Data Center Business Group and has extensive experience in Horizon View, virtualization infrastructure and management, Cisco UCS and storage.  Ramesh assembled a test platform based on the setup shown in Figure 1.

Figure 1: Cisco CVD Validation Platform

As you can see the core pillars of the solution are:

Key things we wanted to expose/profile in this effort included:

  • More with less – more powerful processors and faster memory
  • System footprint for delivering 2,000 Horizon View desktops, while still retaining room to expand as demand increases
  • Leverage more economical processors – ex: a 57% lower list price for the Intel E5-2680 v2 10-core processors vs. top bin processors tested in the past = lower server cost = lower per desktop CAPEX
  • Hosting density leadership (# desktops per compute blade)
  • End user experience as exercised using LoginVSI with medium workload with Flash
  • Boot-up and login performance (simulating the Monday-morning boot storm dilemma all VDI implementations face and daily login storms)·

From a design perspective we also wanted to ensure our system provided:

  • Full n+1 fault tolerance across the stack
  • Fully virtualized platform, inclusive of the virtual desktops, as well as the infrastructure componentry like vCenter, AD, SQL servers etc.

I’ll leave it to you the explore the methodology Ramesh followed for the CVD, but let me point to a couple interesting things gained from this effort:

  • With our B200 M3 blade, we increased our desktop workload capacity (across the system) by 30% compared with full-width blades used in prior analyses
  • We collapsed the footprint from 30 RU down to just 12 RU.
  • The combined effect of the selected CPU (Intel Ivy Bridge), high-bandwidth, low-latency unified fabric, and our VIC 1240 converged networking adapter yielded exceptional user experience at under 1.75 sec at full load.
  • The EMC VNX5600 provided outstanding storage performance for both file and block, using EMC Fast Cache technology.
  • VMware Horizon View 5.3 with Sparse Virtual Disk gave us better disk performance and disk space efficiency.

And as for the 16 minute thing?

  • That’s how long it took for the full population of 2,000 virtual desktops to get booted and ready to login (under 16 minutes).  And in an additional 14 we had all of them running user workload with no sign of exhausting the system.
