Filling the Gap: LINBIT SDS in Amazon EKS

Reader Bootstrapping: Amazon Elastic Kubernetes Service (EKS) might be one of the quickest routes an organization can take to run a highly available, fault tolerant, and scalable Kubernetes cluster. EKS handles many of the difficult tasks in managing a Kubernetes cluster for its users; letting them focus more on their applications than their infrastructure. For […]

Software-Defined Storage Solves High-Availability & Disaster Recovery Problems

Software-defined storage (SDS) is a technology used in data storage management that intentionally divides storage duties of software and hardware1. Software is responsible for: Provisioning capacity Protecting data Controlling data placement Physical hardware is where the actual data (the 0s and 1s) is2 stored. SDS allows the storage hardware to be replaced, updated, and extended without […]

Best Practices for Kubernetes Storage Performance with LINSTOR

LINSTOR® is the LINBIT® SDS solution for managing Linux block storage. If you’ve used LINSTOR, you know how many knobs can be turned when configuring it. If you’ve followed along with one of our quickstart blogs or a README in one of LINBIT’s GitHub repositories, you’ve probably set up a LINSTOR cluster without much consideration […]

Using Virtual Data Optimizer (VDO) with DRBD on RHEL 9 Tech Guide

The purpose of this guide is to provide installation and configuration instructions for implementing Red Hat’s Virtual Data Optimizer (VDO) and LINBIT®’s DRBD®. VDO is a virtual block device driver that provides inline deduplication, compression, and thin provisioning for block storage in Linux. VDO operates within the Linux kernel and is managed by LVM. DRBD […]

Implement Fencing Within a Pacemaker-Managed Cluster Using DRBD 9’s Quorum Feature

Implementing fencing properly is a way to ensure the consistency of your replicated data by avoiding “split-brain” scenarios. When communication between cluster nodes breaks, fencing prevents the data from diverging among your replicas. DRBD® and Pacemaker each have their own implementations of fencing. To be clear, this article only talks about how to achieve fencing […]

Highly Available NVMe-oF on RHEL 9 Tech Guide

The Highly Available NVMe-oF on RHEL 9 tech guide will instruct the reader on how to configure a Highly Available (HA) NVM Express over Fabrics (NVMe-oF) cluster using DRBD® 9 from LINBIT® and the Pacemaker cluster stack on Red Hat Enterprise Linux (RHEL) 9. NVMe-oF is the concept of connecting to a remote NVM Express […]
