Two things I greatly enjoy about working in and around Data Centers are that so many different technologies converge within them and that those technologies are constantly evolving. There’s always something new to explore.
Server virtualization has become mainstream and has changed the way resources are provisioned and accessed within the data center. (Did you know the number of virtual machine shipments now exceeds the number of physical servers being shipped?). Effective measurement and characterization of complex applications in virtual environments is critical to both vendors and customers.
The Transaction Processing Performance Council (TPC) today announced a new industry standard benchmark suite, TPC-VMS (Virtual Measurement of Single-system), that enables comparison of performance, price-performance and energy efficiency of database applications in a virtualized environment.
The benchmark suite is built upon existing TPC standards: TPC-C, TPC-E, TPC-H and TPC-DS. The benchmark test sponsor chooses one of these workloads, and runs three equally sized instances of the same workload on three virtual machines on the system under test. The primary performance metric is the slowest of the three instances and is reported as VMStpmC (for TPC-C), VMStpsE (for TPC-E), VMSQphH@Size (for TPC-H) or VMSQphDS@Size (for TPC-DS).

A common refrain in the wireless world is “everything, everywhere”, but up until now there’s been one place wireless communications has not reached: underground.
When Virgin Media came to us with the opportunity to work together to design and build a Wi-Fi network that would bring mobile broadband to passengers of the London Underground subway system, we jumped at the chance.
Working together with Transport for London, the transportation authority for all London mass transit systems, Cisco and Virgin designed and built a Wi-Fi network that would not only bring a reliable broadband signal to London Underground’s stations, but would be robust and durable enough to withstand the less-than-ideal environment existing under the streets of London.

“Elbows off the table,” “say please and thank you”; these are just some of the words I used to hear growing up. Over the years I’ve learned how important manners are in presenting yourself to others in the best way possible.
That’s why Cisco TelePresence has put together a few tips on telepresence etiquette to ensure you’re showing your BEST side in any video interaction.
