Setting up Portworx on a Tanzu Kubernetes Grid aka TKG Cluster
First, this process works today on clusters made with the TKG tool that does not use the embedded management cluster. For clarity I call those clusters TKC or TKC Guest Clusters. The run as VM’s. You just can’t add block devices outside of the Cloud Native Storage (VMware’s CSI Driver). At least I couldn’t. Now […]

OpenStack Cinder Replication: Using Multiple ActiveCluster Pods to Increase Scale
Since the Mitaka release of OpenStack, the Pure Storage Cinder driver has supported Cinder replication, although this first iteration only supported asynchronous replication. The Rocky release of OpenStack saw Pure’s Cinder driver support synchronous replication by integrating our ActiveCluster feature from the FlashArray. This synchronous replication automatically created an ActiveCluster pod on the paired FlashArrays […]

Kubernetes on AWS with Cloud Block Store
Only a slight nudge at from @CodyHosterman to put this post together. Kubernetes deployed into AWS is a method many organizations are using to get into using K8s. Whether you deploy K8s with Kubeadm, Kops, Kubespray, Rancher, WeaveWorks, OpenShift, etc the next big question is how do I do persistent volumes? While EBS has StorageClass […]

Start with Applications
I have been revisiting my work towards some advanced datacenter certifications and decided to journal some of the thoughts I have during the process. After a 3 year break I decided it was time to start pushing toward some of these goals. This may sound eerily similar to something I have said before. It is […]

In any work environment there is constant posturing, politicing, conflicting, that has nothing to do with the actual cause of the workplace. I am […]

Some Reality for us Infrastructure Peeps or Apps are cool too
Don’t’ you just love double titles? For many years I have been an infrastructure guy. I really liked how the cables, and processors and Memory and blinking lights worked. Applications were often the necessary evil tolerated so that I can play with cool technology. During my own journey toward learning about the cloud it becomes […]

Its About the Apps – The Need for Application Modernization Webcast
As we migrate to Cloud models for Enterprise IT one big need that gets overlooked is how the applications are architected. Modernizing existing apps can be a very scary but a necessary step to taking advantage of what the cloud can offer. Just look at this crazy puzzle. As a VMware/Network/Storage geek I spend so […]

vSphere Metro Stretched Clusters – Some Info/Links
A lot of questions lately about vSphere Clusters across distance. I really need to learn for myself so I collected some good links. Make sure you understand what “Only Non-uniform host access configuration is supported” means. Someone correct me if I have this wrong but your device that enables the distributed virtual storage needs to […]

An Idea for vCloud Director and View
Sometimes I am sitting up late at night and I have a thought of something I think would be cool, like if x and y worked together to get z. This time I thought this was good enough to blog about. Now I want to stress that I do not have any special insight into […]
