Using 1 GbE would have required too many ports, too many cables, and too many switches; 10 GbE offered Expedient a 23% reduction in cables and ports, a 14% reduction in infrastructure costs, and offered a significant bandwidth improvement (compared to the previous 1 GbE architecture). Note that there are trade-offs as a result.)

The two big recent entrants/announcements were Ciscos Unified Computing System (made this past March) and then HPs BladeSystem Matrix (made in June). The UCS Manager software bundled with the system provides core functionality (see diagram, right). Still, these systems are - believe it or not - a major step forward in IT management.

.” The speakers are Recep Ozdag, a PME with Intel, and Gershon Schatzberg, a PLM with Wind River Systems. Recep will cover the hardware side of ONP; Gershon will cover the software side of ONP (referred to as ONS). ONP fits into this picture by performing VTEP functions in hardware (at line rate). So how does this work?

Whether it is redundant hardware or a private hot-site, keeping an environment up and running 99.99% (insert more 9’s here) of the time is a tough job. With a well-planned deployment, and a good infrastructure, companies can efficiently load-balance their IT environment between multiple active, cloud-based, sites.

A specific angle I want to address here is that of infrastructure automation ; that is, the dynamic manipulation of physical resources (virtualized or not) such as I/O, networking, load balancing, and storage connections - Sometimes referred to as "Infrastructure 2.0". a Fabric), and network switches, load balancers, etc.
