Various thoughts on Oracle, Enterprise Architecture, Cloud Computing, Kubernetes and everything Storage
Introduction By default, Portworx thin provisions volumes and balances them according to current usage and load within the cluster, requiring only minimal configuration. This approach enables applications to provision volumes simply as long as you have enough backing storage for the volume usage. However if the volume usage exceeds your available backing storage, and allocating... Continue Reading →
Introduction If you follow my blog or have read my post Oracle Database 19c on Kubernetes with Portworx storage you may have an Oracle database running on Kubernetes and are wondering how do I protect it. In this post I will show you how we can use Portworx Volume Group Snapshots to complement other backup strategies.... Continue Reading →
Background In this post I am going to walkthrough how you can get, and install the Oracle ZFS Storage Appliance simulator on VirtualBox. I will then share how we can create an NFS filesystem and configure SNMP to support HCC (Hybrid Columnar Compression). Download OVA Start by downloading the 3.4GB Oracle Storage Appliance Simulator software... Continue Reading →
Background Historically most of the conversations I have regarding Oracle Recovery Manager (RMAN) are around the use of NFS storage such as a Pure Storage FlashBlade, and Oracle Direct NFS (dNFS). However, with more Oracle customers deploying databases in Oracle Cloud Infrastructure (OCI) and / or using Object Storage for backups I thought it was... Continue Reading →
Background In my last post I shared how to deploy Portworx by Pure Storage on the Oracle Container Engine for Kubernetes (OKE) within the Oracle Cloud Infrastructure (OCI). In this post I will share how we can automate the build of an OKE cluster using Terraform. Terraform for Oracle Cloud Infrastructure (OCI) If you want... Continue Reading →
Oracle Cloud Infrastructure (OCI) In this blog I will show how we can use Portworx with the Oracle Container Engine for Kubernetes (OKE) service within the Oracle Cloud. For this post I created a 5 node OKE cluster and 5 Block devices which I attached to each compute instance using iSCSI. OCI Compute Instances OCI... Continue Reading →
In this post I am going to show how we can take volume and volume group snapshots with Portworx. I have previous blogged on how you can run an Oracle 19c on Kubernetes with Portworx and will use the PVCs created that blog within this post. Inspect existing Statefulset Before we start let's looks out... Continue Reading →
In this post I will share how we can check the status of our Portworx licence, and if expired how we can reactivate it. Portworx Status Let's start by checking the status of our Portworx licence, we can do this with the Portworx CLI (command line interface) pxctl status command. [root@node-1-1 ~]# pxctl status Status:... Continue Reading →
Background In my previous post I walked through how you can determine a vVOL FlashArray volume from a Linux device. In this post I will show how we can automate that process with Ansible using the same /dev/sdd Linux device and some code examples. Ansible Linux Facts Let's start by using the ansible_facts.devices to identify... Continue Reading →
Background I have recently seen an increase in the adoption of VMware Virtual Volumes (vVOLS), and a question which is frequently asked is: How I can identify the FlashArray volume from my Linux server ? Identify Linux Device In this example my Oracle database is using a Pure Storage FlashArray and has been migrated to... Continue Reading →
