13½ Interesting Questions about SD-WAN

Ethan Banks raised some thought provoking questions around SD-WAN on his blog. Here’s our response to those questions. 1) What’s the impact to hosts on virtual machine based endpoints, i.e. how much CPU does an SD-WAN VM eat for solutions that use VMs? Not a simple question to answer anymore, as there’s usually cryptography involved. Silver […]

Your Network Needs Agility — Whatcha Gonna Do?

Remember in the old World Wrestling Federation days when Mean Gene Okerlund would interview all of the wrestlers and each one would have their own tag line? Rick Flair’s was a simple “woo!” while Hacksaw Jim Duggin would scream “oh-ooh!” Hulk Hogan’s might have been the most memorable when he would ask his next opponent, […]

It’s The Software, Stupid! But Also The Hardware And ASICs

The mania around software is at an all-time high. Everyone is a software vendor and it seems no one wants to be in the hardware business anymore. Software is the new, sexy item and people flock to software solutions like teens flock to Taylor Swift — hardware is so last century. However, I think it’s […]

Extending VMware vSphere 6 Replication over the WAN

Data protection is essential for business continuity and disaster recovery, and that includes the protection of virtual machines (VMs). Today at VMware Partner Exchange 2015, Silver Peak announced that our WAN optimization software has tested and pre-validated the new VMware vSphere® 6 Replication solution to accelerate remote replication. VMware vSphere 6 Replication provides an efficient […]

The IoT is About New Experiences, Not Just Connected Things

2014 was a big year for the Internet of Things (IoT). Much of the focus of IoT has been on the topic of connected things. I actually wrote about connected devices in this blog on five different IoT solutions that we might find useful. I touched on a few connected devices but there are literally […]

Understanding Service Chaining

One of the emerging topics of conversation related to Software-Defined Networking (SDN) has been something called “service chaining”. The topic has gotten a fair bit of media focus of late, resulting in an increase in the amount of inquiry on this topic. From the questions I’ve been getting, though, its become obvious to me that […]

The Growing Need For Intelligent Workload Management

Life used to be so good. An operating system was loaded onto a server of some sort and an application stack loaded on top of that. Provided the workload remained pretty static, the performance was pretty much guaranteed. The problem was that most workloads weren’t static. As such, resource ceilings were often hit, and the […]

Mobile Security Strategy Shift: Wrap The App

With the fast growth in mobile devices being used to access corporate applications and data, board-level GRC (governance, risk & compliance) requirements for mobile security need to be on par with the security demanded of all other devices used to access corporate applications. The GRC process often results in approval bottlenecks on the mobile side, […]

Is Software-Defined Storage A Solution In Search Of A Problem?

Software-defined storage, or SDS, seems such a great idea. After all, when we are faced by a new project most of us still think in terms of how many drives to buy for it, yet the fact is that we can never know what that project will need as it evolves, so we almost always […]

Why ONUG Has It Right

I recently got back from spending two days at the Open Networking User Group (ONUG) conference in New York. Kudos to Credit Suisse for hosting the event and to ONUG leadership for organizing it. It was exciting to meet forward-thinking IT leaders and hear about their need for an open networking standard. Nick Lippis, co-chair […]
