The Dirty Secrets of Server Power

Power efficiency remains a top decision point for many customers looking to modernize their data center. Customers searching for an accurate way to compare server power among vendors are often directed to use power calculators without taking into account the many factors that drive power utilization. This notion preys on the simplistic nature of the power beast – lower number is better… but are we missing the (power) bus entirely?

The dirty little secret is that there is no industry standard for power calculators, and vendors can essentially publish a calculator around whatever workload they like (or no actual workload at all). Read More »

Now is the time to refresh to Cisco UCS!

Intel estimates1 that one-third of the servers in production are more than four years old. At first, one might think that it is great to get this much service out of a capital investment, but the operational costs to run these outdated servers would pay for a complete technology refresh increasing performance and reliability while reducing total costs. How is this possible? With the Intel® Xeon® Processor E5-2600 v2 product family and Cisco’s Unified Computing System. Read More »

The One and Only Cisco UCS Manager

I am often asked by customers why UCS has been so successful in such a short amount of time. My response is always the same in that it comes down to two things – 1) Cisco and our partners’ ability to understand and execute against customer needs and 2) A fundamental difference in the underlying architecture.

You may know that Cisco invented UCS service profiles and built the entire system around the notion of hardware state abstraction. Cisco’s approach has been so successful because every element of the system was designed from the beginning to have its configuration set through software, without any licensing requirements. Whether customers are running bare-metal, virtualized, or any combination therein, Cisco UCS service profiles have revolutionized computing and have challenged competitors to try and replicate the simplicity and increased productivity that UCS Manager policies and templates provide. It’s no secret that Cisco UCS Manager has revolutionized the way customers deploy and manage servers, but here are a few things about UCS Manager that you may not be aware of.

Did you know that Cisco UCS Manager is embedded software running within the Fabric Interconnects in a highly available clustered configuration? This is an important distinction from traditional architectures as Cisco UCS Manager is a fully redundant management engine right out of the box the moment the system receives power, without special clustering software or additional licensing fees.

Redux: Yes, Cisco UCS servers are that good

Almost a year ago, I wrote my first blog post detailing what customers have been saying about their UCS experiences in our Case Studies, Solution Briefs, etc.

The findings have been updated with the latest studies. While the percentages haven’t changed much, the number of customers reporting similar results (like Cisco’s market share) has gone up dramatically.

These results are limited to where the customers specifically stated a savings or where the savings is easily derived from the numbers stated.

  • 61% reduction of ongoing administrative/management costs based on 27 customers.
  • 54% reduction in power & cooling based on 44 customers.
  • 77% reduction in cabling with an average cost savings of 71% based on 21 & 6 customers respectively.
  • 41% reduction in other operations costs based on 13 customers
  • 84% reduction in provisioning times based on 71 customers.

To help explain how customers achieved these results, the Cisco Unified Computing System (UCS): Changing the Economics of the Datacenter presentation walks you through UCS technology innovations and how they lead to TCO improvements. Along with this data, the presentation has been updated with current cost comparisons as well as third party deployment test reports.

Cisco UCS Outperforms HP and IBM Blade Servers on East-West Latency

Virtualization, Private Cloud, Big Data, HPC, etc. have been steadily changing the landscape of data center architectures. Lower latency and higher performing server-to-server data traffic (East-West) have become key discussion points as customers look to modernize their infrastructures.  Cisco specifically designed UCS unified fabric for this type of traffic to create a highly-available infrastructure with reduced latency and unmatched consistency as the solution scales. Without providing any supporting data, HP and IBM have been incorrectly asserting that Cisco UCS unified fabric would increase latency and slow blade-to-blade traffic. Cisco ran the tests, and the results were simply amazing.
