Network Functions Virtualization Enables Cost-Effective Route Reflectors

One of the concerns I hear from network managers regarding all things software defined networks (SDNs) is the lack of use cases for the new technology.  It seems the technology promises to solve so many problems that it’s hard to understand where to start.  Network Functions Virtualization (NFV) is no different.  Lots of possibilities, but […]

Hardware: Beginning of the End, or End of the Beginning?

In a recent post here on WANSpeak, Zeus Kerravala, Principal Analyst at ZK Research, stated that he has evolved from trying to make the case that a software-defined WAN is a good alternative to a traditional WAN, to believing that the SDW should be the only type of wide area network that companies should even […]

The Pollock Platform: Network as Abstract Art

Jackson Pollock was the father of “action painting”, dripping paint on to canvas and even using jet engines to create his abstract art, now worth millions on the art market.  Although he used the same basic resources as any other painter (oils and canvas), he used different techniques to create something that is pretty easily […]

Faster Data Recovery with Dell SC-Series Storage and Silver Peak (Video)

A financial institution with nearly 50 locations throughout California, Citizens Business Bank achieved faster data recovery by combining Silver Peak data acceleration software with Dell SC-Series Storage. Today, at the Dell User Forum in Miami, Dell introduced the new Dell Storage SC4000 Series arrays. These bring high-end storage capabilities to mid-sized deployments, offering all-flash performance for up […]

Branch Office of the Future: An IT Blueprint (Infographic)

Branch offices have long posed a challenge for distributed organizations. Where server consolidation is impossible, some have deployed proprietary, all-in-one appliances in the branch incurring marked increases in capital and operational costs. But there is a different approach. By coupling data acceleration software with the advances in hypervisor technologies and server designs, IT can solve […]

Will Virtual Overlay Networks Cause “Network Sprawl”?

It’s hard to have any discussion with any networking person today without the term “Software Defined Networks” (SDNs) coming up within the first five minutes. However, what I’m starting to see are discussions occurring a level down from the über term of just “SDN”. Topics like Network Functions Virtualization (NFV) and programmability of the network […]

Network Fabric for Healthcare: A No-Brainer

The concept of a network fabric has been around for a few years now, but deployments have been spotty.  One of the reasons for this sparseness is that it’s tough to come up with any kind of ROI around a network upgrade, particularly in the data center where you’re talking about pricey infrastructure. To combat […]

Is NFV Hotter than SDN?

For the last couple of years, SDN has been the hottest topic in networking.  Over that timeframe we have been constantly bombarded by differing messages about exactly what SDN is, but those messages have had a constant theme:  SDN is coming, and it’s coming soon.  I don’t doubt that SDN is coming, but given recent […]

IMServ Builds Software Defined WAN for Data Protection

Faced with a static infrastructure, IMServ’s technical team was finding it difficult to cope with the exponential growth of current and historic data it was starting to manage. Covering more than 400 servers and around 250 users, IMServ manages highly time critical secure customer data and relies heavily on high network performance, stability, and availability. One […]
