Although calculating the metric is a relatively straightforward exercise, the resulting score doesn’t tell you anything about the factors that influenced it. Hence why it’s a bad idea to compare PUE among Data Centers.
I went shopping for a car last year and was pleased to see several models equipped with real-time displays of their miles per gallon performance. That’s a great feature, in my opinion, because it offers drivers up-to-the-moment insight into how efficiently their cars are operating.
If sibling rivalry exists among Data Centers, our Richardson, Texas facility must be jealous. Unveiled in 2007 as Cisco’s next-generation Data Center and subsequently toured by thousands of visitors, the site hasn’t received much attention since its younger brother came online in 2011. Read More »
One part of my job involves designing the virtualization model for our internal unified communications (UC) system deployments around the world. A critical task in this design is specifying which UC virtual machines (VMs) can share a Cisco Unified Computing System (Cisco UCS) server chassis or blade and which ones can’t. When migrating UC servers to a shared virtual environment, we need to make sure we carefully balance each VM’s needs for CPU, storage, network and memory. Read More »
Cisco IT continues to improve upon virtualization and cloud computing capabilities in its Allen, Texas data center. We have added new capabilities in recent months that improve the self-service features available to users. On the Cisco IT Elastic Infrastructure Services (CITEIS) platform, Cisco’s private cloud, users now have the capability to create virtual machines. Additionally, they can enable middleware such as Apache web servers and WebLogic app servers.
