SDN

Today’s networks do not scale or perform well for the amount of virtualized servers and the volume of devices they must support. East-west traffic (server to server) accounts for 70-80% of all in-data center network traffic depending on the data center. The number of virtual machines requiring network resources is growing daily. The problem with today’s network architectures lies in the complexity needed to support a very different compute environment than a few years ago.

How SDN Can Redefine Whitespace

Software Defined Networking (SDN) is more than another TLA (Three Letter Acronym). It promises to allow rapid deployment and redeployment of networking resources not by the old fork lift method, but rather through software. If you think of the possibilities here, they are pretty amazing. Suppose you could design a data center and its whitespace contents once. Then once installed, perform moves and changes in software. Adds obviously would require more labor, so I’m not covering that in this blog.

Do you really need a high density data center?

It never ceases to amaze me how many vendors tout a “one size fits all” solution. Even in a certain sector or company, the needs are varied. Across hundreds of data centers the needs are even more varied. If we look at typical Watts per cabinet, the international average is 5.5-6.0. This is certainly not what we would deem high density. Many colocation and hosted facilities are designed to these lower numbers as well. If you need more power, you simply rent more space. If you talk to any colo provider, they will be the first to tell you that managing power across all customers is a full time job as none of the cages require the same power requirements.

Big Data – Big Dilemmas

There is lots of talk of big data. In short big data is just another term for analyzing an increasing amount of information that is gathered year over year about our daily lives, browsing habbits, etc. Take the following example: Suppose you were searching on baby names on the internet. The next time you log onto your favorite retailer’s site, they can tell by your history that you researched baby names. This now puts you in line for a barrage of coupons for baby diapers, strollers, supplies, etc. While the system won’t be perfect, you may not have been searching for yourself, you can forward the coupons on to the person that really was searching for the baby names and bingo- job accomplished. The coupon got into the hands of the person that would need them.

I’m Afraid of the Cloud Because….

Companies are moving to cloud services. There is no denying the shift. Companies are not moving their entire data center to the cloud, but many are moving at least some applications to the cloud either permanently or temporarily. But what is really moving to the cloud? If you believe the statistics from the cloud providers, one would think that there are massive numbers of companies moving swiftly and rapidly to the public cloud or hybrid cloud. The problem with the cloud statistics is that “cloud” is overused, over-confused, and over-abused.

Are Fabrics/Unified Computing the Solution for Rapid Deployment and ease?

This question has been posed to me several times. My answer is…that depends on the question! Fabrics do provide some advantages for some and not so much for others. For instance in a cluster environment for high speed computing, or when a company needs to rapidly deploy storage, servers and networking . However, I think the real answer is that there isn’t an “end all be all” to every data center as needs vary from one DC to another and from one application to another in a data center.
