The enterprise’s insatiable demand for bandwidth shows no signs of letting up any time soon. In fact, if current trends continue, it’s about to expand dramatically both inside the data center and on wide area infrastructure. But adding bandwidth is not simply a matter of widening the pipe. More bandwidth means more complexity, faster throughput and improved layering and segmentation to accommodate workloads of various types and sizes. And it all has to be done with an eye toward the future so you don’t end up repeating the process a few short years from now ...

If things work out the way proponents hope, software-defined WANs will make tying corporate locations together far more efficient, increase functionality and reduce costs. SD-WANs are an implementation of software-defined networks. Today, network elements are purpose-built physical devices. If a company wants a firewall to protect an office, it calls a service provider or carrier who sends out a guy – it always was a guy – with a firewall in a truck. He deploys it into the network ...

A seismic shift is underway in enterprise data centers. SCSI-based, all-flash and hybrid arrays are becoming mainstream in the new generation of software-defined data centers. This is driving enterprise and cloud storage to new levels of performance and causing a reassessment of performance bottlenecks. Recently, non-volatile memory express (NVMe), a PCI Express (PCIe) standard that is purpose-built for solid-state PCIe modules in servers, has emerged as a new high-performance interface for server-attached flash ...

The software-defined wide area network (SD-WAN) is emerging as one of the hottest growth areas for the enterprise. With the demands of mobile users, the IoT and the emerging digital services market continuously pushing virtualized infrastructure past the data center to the cloud and beyond, organizations are in dire need of rapid provisioning and agile connectivity over the long haul. But this is leading to a conundrum of sorts: Is it better to adopt a fully managed SD-WAN or should control be preserved in-house? Or is there even a middle-ground that alleviates much of the day-to-day burdens without risking availability or data integrity?

Software-defined WAN (SD-WAN) got its start as a way for end users to save money. SD-WAN let users create their own virtual private networks (VPNs) using low-cost broadband connections. Users quickly learned that being their own network operator brought a lot of unwanted complexity and headaches. Now, these same enterprises are asking service providers to offer managed SD-WAN services ...
