Businesses are moving away from their dependence on an ever-increasing variety of non-virtualized, dedicated, proprietary physical solutions. Instead, they are moving to agile, high performance, high throughput, and highly efficient virtualization solutions.
In order to be cloud ready, these virtualization solutions need to span across server, storage, and networking. Fo...r compute and I/O intensive applications and architectures that require high bandwidth and predictable latency, businesses typically discover that it is not enough to just deploy flexible, virtual server applications—the underlying I/O must also be flexible, virtual, and easy to configure and deploy.
Historically, traditional core networks used custom hardware based on the need for performance and capabilities that standard off-the-shelf hardware did not provide. This left the intelligence of the network embedded in custom hardware and chipsets that were expensive to buy, difficult to manage, and slow to change. These non-virtualized, legacy solutions also kept businesses locked into dedicated, proprietary hardware, and inflexible legacy applications and architectures.
