Persistent Storage Solutions for Kubernetes Using LINBIT’s Software: HCI, Disaggregated, & NAS
LINBIT® has been growing its catalog of open source storage and high-availability (HA) clustering software for many years with various drivers, plugins, and platforms all with DRBD® at their core. I often refer to DRBD as a “Swiss army knife of replication” because DRBD doesn’t care what application is writing to it or what those writes look […]
Monitoring Clusters Using Prometheus & DRBD Reactor
UPDATE 5/15/2023: While the ha_cluster_exporter project is still active and well, LINBIT® now has their own software, DRBD® Reactor, for exporting Prometheus metrics specific to DRBD. This blog post will highlight LINBIT software with native Prometheus instrumentation, as well as pointing you in the right direction for integrating them into your Prometheus monitoring strategy. Prometheus […]
Kubernetes High Availability for Stateful Workloads
LINBIT® is a company with deep roots in Linux High Availability (HA). Because of this, LINBIT has some opinions on what HA is, and how it can be achieved. Kubernetes’ approach to HA generally involves sprawling many replicas of an application across many cluster nodes, therefore making it less impactful when a single node or application […]
Comparing LINSTOR & Ceph Storage Clusters
Over the many years that I’ve worked for LINBIT, I cannot tell you how many times I’ve been asked, “How does a LINSTOR® (and/or DRBD®) cluster compare to a Ceph storage cluster?” Hopefully I can help answer that question in this blog post for anyone who might Google this in the future. My short answer could […]
Benchmarking on Ampere Altra Max Platform with LINBIT SDS
Ampere® and LINBIT® collaborated on some exciting benchmarking of Ampere’s Altra® Max Platform using LINBIT SDS to manage and replicate some seriously fast Samsung PM1733a SSD drives and are ready to start sharing our results. The exhaustive hardware and software configurations, as well as the testing methods used along with their results can be found […]
Create a Docker Swarm with Volume Replication Using LINBIT SDS
With container orchestrators like Kubernetes, OpenShift, and Nomad often taking the spotlight, Docker swarm hasn’t been getting as much attention. That doesn’t mean we’ve forgotten about it! Docker swarm is known for being easy to learn and use, making it an appealing container orchestration platform for smaller teams, or anyone looking to focus more on […]
Using Fencing in Pacemaker Clusters on VirtualBox Hypervisors
This post will describe how you can configure the fence_vbox fence agent in high-availability (HA) Pacemaker development clusters running on VirtualBox for Linux. Fencing is an important concept in HA clustering, so using fencing in development as you would in production is a practice that can help align the development experience with that of a user running […]
AWS Marketplace Listing for LINSTOR, DRBD, & DRBD Reactor
It has never been easier to use LINBIT®’s suite of storage and high availability (HA) tools in AWS. LINBIT recently added a free to use AMI listing to the AWS Marketplace based on the latest Ubuntu LTS release with LINBIT’s Ubuntu Personal Package Archive (PPA) preconfigured and LINBIT’s packages preinstalled. What’s in the Box? Out […]
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 […]
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 […]
