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 […]

Deploy a Highly Available MariaDB Service Using LINSTOR & DRBD Reactor Tech Guide
You can quickly and easily deploy a high-availability (HA) MariaDB service by using LINBIT SDS components and DRBD Reactor as a cluster manager. Making your database service highly available, especially if it’s the back-end service to a crucial application or other service, can help keep your customers or coworkers who depend on it up and […]
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 […]
Highly Available KVM Virtualization Using DRBD & Pacemaker Tech Guide
One of the many use cases for DRBD® replication technology is to replicate a device that backs a storage volume that is in a backing storage role for a KVM virtual machine (VM) image. You can use this replication strategy, with Pacemaker configured as the cluster manager, to create a high-availability (HA) KVM virtualization solution. […]
Open Source Workload Orchestrators
LINBIT® SDS is available for Kubernetes (and OpenShift), Apache CloudStack, Open Stack, OpenNebula, XCP-ng, and Proxmox. When I think of a name for these, I always return to ‘Open source workload orchestrators.’ So far, there is one name missing from that list: oVirt. oVirt is the Open Source upstream for Oracle Virtualization Manager and Red Hat […]
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 […]
