Since the earliest days of ONTAP, snapshots have been a feature which has played a significant role in providing point-in-time recovery options for data which has been lost or corrupted accidentally. They are instant, space efficient, and, when the snapshot directory is turned on for the volume, provide the application or user a way to … Read more
Overview PostgreSQL is a popular open-source relational database, and in this post you will see how you can deploy PostgreSQL in a Kubernetes environment using Helm charts with Trident, a dynamic storage provisioner from NetApp for Kubernetes.

A couple of months ago, our team received the mandate to set up a Red Hat OpenShift cluster in offline mode to support a brilliant use case for gaining performance insight. I was very excited. I use the word “excited” because it’s fascinating to see how Kubernetes has become one of the fastest-growing open-source projects … Read more
Trident 17.07 introduced a simplified management tool for interacting with Trident: tridentctl. This command line tool eliminates the previous method of using shell scripts inside the Trident containers and instead introduces a paradigm which mimics Kubernetes own kubectl. Let’s look at how to use tridentctl to interact with, and get information from, Trident. Managing the … Read more

This helps break down a large barrier that has traditionally existed between the consumers of … Read more
Introduction In this post we will show how to deploy a “stateless” Apache Spark cluster on Kubernetes. Spark is a fast analytics engine designed for large-scale data processing. Furthermore, we will then run analytics queries against data sitting in S3, in our case StorageGRID Webscale. We use S3 as the data source/target because it is an elegant … Read more
