Sniffing Out a Data Center’s PUE

April 10, 2013 at 10:30 am PST

Power Usage Effectiveness or PUE, is the most commonly used metric in Data Centers today.  Data Center industry organizations tout it, major companies brag about their scores, and energy efficiency certifications use it in their ratings.

Despite how thoroughly it has been embraced, though, it’s not without flaws.  In my opinion, they mostly stem from the fact that PUE is more complicated than it looks.  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.

Deep Dive into Converged Wired and Wireless Access April 17

April 10, 2013 at 10:18 am PST

Last week we kicked off the first webinar of a new 5-part Cisco Unified Access webinar series. Many of you joined the event and I was very happy to see your questions and discussions during the broadcast. The event was a high level overview of industry challenges with BYOD, mobility and the Internet of Everything, as well as how Cisco Unified Access can help address these challenges with the One Policy, One Management, One Network approach.

Next week on Wednesday April 17, we will have the 2nd live broadcast of the Cisco Unified Access webinar series. We will have excellent technical content to dig deeper into the subject of “One Network”, specifically converged wired and wireless access (CLICK HERE TO REGISTER) and we will be covering a lot of technical topics such as your above questions. See more a the Borderless Blog.

Compliance versus Security

Rogue access points and unauthorized access, DDoS or penetration attacks, evil twin attacks – all mobile security issues that can keep you awake at night. But do you know the difference between compliance and enterprise security? Being compliant is not synonymous with being secure, that’s why our webcast on April 16, is focused on how to bridge the gap between PCI compliance and security to minimize the impact of an attack.

World IPv6 Congress – “The Buzz“

simlo

By Steve Simlo, IPv6 Product Manager, Cisco Network Operating Systems Technology Group

The World IPv6  MPLS / Ethernet / SDN World Congress events wrapped up recently with over 500 industry specialists in attendance, including myself. For 3 days the buzz was on how IPv6 has advanced since last year’s World IPv6 Launch to become reality.

Day One focused on Mobile, Day Two on Bring Your Own Device (BYOD), Home networking and emerging Cloud and Core applications of IPv6 and Day Three looked at Security and Measurements.

Here is my personal summary of a few of the items that I found most compelling:

1. Mobile IPv6 based deployments are happening now. Providers such as Verizon and T-Mobile are offering real services over LTE. In addition we are seeing some emerging niche services such as the “Advanced Emergency Response Service” in Slovenia being deployed to leverage some of the emerging advanced capabilities of IPv6 in terms of QoS, policing, marking and advanced unicast and multicast routing.

Expanded Cisco Validated Design Options for Oracle Users


Collaborate 13
, the largest independent Oracle user group (IOUG, OAUG, Quest International) event is the launch point for 3 new Oracle-based, Cisco Validated Designs (CVD).  With the Joint Cisco/NetApp “FlexPod” as the hardware platform, the new CVD’s include:

            • Oracle RAC with Oracle Linux as the operating system
            • Oracle RAC with Oracle VM as the hypervisor
            • Oracle’s JD Edwards EnterpriseOne with Oracle Linux as the operating system

New Oracle based CVDs built on FlexPod from Cisco Data Center

These CVD’s, Prevalidated for Oracle, give Oracle RAC and Oracle’s JD Edwards EnterpriseOne users the option to select a fully tested and supported solution for their infrastructure.

IT users face a difficult series of challenges; do more and do it better, but do it with lower budgets and staff levels.  Prevalidated systems, like these three new FlexPod-based CVDs for Oracle software, can help address these challenges.

Cisco and NetApp, working with software companies such as Oracle, are able to give customers a potent weapon to help IT organizations drive down complexity and deliver prevalidated, converged infrastructure capabilities for their mission critical databases and applications.  High availability and fast, reliable performance are benefits of converged infrastructure platforms like FlexPod.
