HP latest to unbundle switch hardware, software
HP has joined the disaggregation party through two partnerships that will produce a branded white box switch capable of running multiple network operating systems.HP has expanded a relationship with Accton Technology to offer two new switches initially, and more later this year. The switches will be low-cost, software-independent white box hardware targeted at Web scale data centers supporting cloud, mobile, social media and big data workloads.Under a second arrangement, HP will offer Cumulus Networks’ Cumulus Linux network operating system on the Accton switches. Cumulus Linux runs on a variety of white box and branded switching hardware based on merchant silicon, and is intended to make the software side of networking hardware independent.To read this article in full or to leave a comment, please click here
In our last post, we looked at how Kubernetes handles the bulk of it’s networking. What we didn’t cover yet, was how to access services deployed in the Kubernetes cluster from outside the cluster. Obviously services that live in pods can be accessed directly as each pod has its own routable IP address. But what if we want something a little more dynamic? What if we used a replication controller to scale our web front end? We have the Kubernetes service, but what I would call its VIP range (Portal Net) isn’t routable on the network. There are a couple of ways to solve this problem. Let’s walk through the problem and talk about a couple of ways to solve it. I’ll demonstrate the way I chose to solve it but that doesn’t imply that there aren’t other better ways as well.
