The Chronicles of Building Cisco’s Allen Data Center

Early in 2010 Cisco started construction on its greenfield data center in Allen, Texas. From inception, the goal was for this facility to embody our data center vision for consolidation, virtualization, cloud computing, and new approaches to power and cooling, uniquely done all under one roof.

Cooling a High-Density Compute Environment

Cisco’s data center in Allen, Texas (DC2), was designed to make best use of the high-density Cisco Unified Computing System and Nexus switches. Cisco’s business requirement for high-density computing, supporting up to five Unified Computing System chassis per rack, essentially quadrupled the per-rack power requirements at Texas DC2 compared to target load requirements at our other data centers.

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.

Multitenancy in the Data Center: Putting a New Paradigm to Work

Imagine if you were a building contractor and a client came to you and said, “I need you to build a commercial facility suitable for a variety of occupants, including a 24-hour machine shop that consumes massive amounts of electricity, a workshop for the disabled full of assistive equipment, and a rare gems dealer who requires maximum security.  Oh – and by the way – they’ve all signed 5-year leases, so your design will have to anticipate their future needs.”

DCI Use Case: Capacity Expansion

Hi,

Today I want to bring up DCI use case that I’ve been thinking about: capacity expansion.  As you know, the purpose of DCI is to connect two or more Data Centers together so that they share resources and deliver services.  The capacity expansion use case is when you have temporary traffic bursts, cloud bursts, either planned or unplanned, maintenance windows, migrations or really any temporary service event that requires additional service capacity.

To start addressing the challenge of meeting these planned and unplanned cloud burst and capacity expansion requirements, check out the new ACE + OTV feature called Dynamic Workload Scaling announced recently.
