Cisco UCS – Quintessential Fabric-based computing – Part 3

In Part 1 of this blog series, we looked at Gartner’s definition of Fabric based infrastructure (FBI). In part 2, we explored the benefits of service profiles and automation of server management. In this last installment, we will look into the benefits of fabric extension to virtual machines.

According to an IDC report (New Economic Model for the Data Center), the rate of growth of virtual machines is much higher than physical machines.  The life cycle of virtual machines is more dynamic than physical servers. Virtual machines may need to be moved from one network to another for data access.  Additionally, typical deployments of virtual machines have an extra layer of switching in the hypervisor.  The software switches in the hypervisor emulate hardware at the expense of application performance. Cisco UCS solves these problems with the Cisco Virtual Interface cards (VICs) acting as adapter fabric extenders (fig 1) and bringing the network to virtual machines (VMs).

Another problem is that network administrators have no control on the soft switches in the hypervisor, which makes monitoring of network traffic to individual VMs very cumbersome. Cisco VICs use the VN-Tag standard in IEEE 802.1 BR standard to manage each link from the VM as if it were a Read More »

Nexus 7009

Our latest TechWiseTV episode is all about the recent announcements rolling out from the Data Center team. We did our best to cram a few handpicked things we liked and give you the detail we thought it deserved.  The theme, and the show title: Evolutionary Fabric, Revolutionary Scale.

The announcements include the most scalable 10 Gigabit Ethernet Layer 2/Layer 3 Fabric in the industry.  The claim is that no matter how diverse your data center demands may be, Cisco offers unparalleled abilities to arm you with efficiency, agility, innovation and differentiation.  So no matter your form factor, physical, virtual or cloud- based environments are all positively impacted with an industry leading fabric-based approach.

Filled with geeky goodness….look at what you will find!

  • 2nd gen Nexus 7000 with revolutionary new scale
  • FabricPath, Adapter FEX, and VM FEX support on Nexus 5500
  • New FEX switch and B22 OEM program
  • Expansions to Nexus 3000 family
  • IN YOUR FACE COMPETITIVE!  Don’t miss the final segment of the show…Jimmy Ray calls out HP, Juniper, Arista….”I showed you mine, now show me yours!”

Watch the entire thing after the jump.
