These days, I have been staying busy preparing for my presentation at STAC Research in London on May 4th. On the same day, Rene will speak at the CloudStack European User Group meeting. Yes, that is Star Wars day! May the 4th be with you. Content In the last couple of newsletters, I have shared information regarding our recent […]
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 […]
High Availability with DRBD Reactor & Promoter
In this blog post, we discuss the DRBD® Reactor and Promoter plug-in. Please read the overview blog post first if you’re looking for a general introduction to DRBD Reactor. This DRBD Reactor & Promoter post first appeared in February 2022. We have updated it for technical accuracy and clarity, referencing a new chapter in the […]
Open Source, Open Hearted: LINBIT’s Shift Towards a More Authentic Newsletter
When it comes to company newsletters, the traditional approach has been maintaining a formal, marketing-driven tone. However, as the business landscape evolves, I believe that many companies are shifting towards a more personal and community-focused approach to their newsletters. I feel that this is especially true in the open-source software industry, where transparency, collaboration, and […]
DRBD Quorum Implementation Updates
The Origins With version 9, we introduced the capability of building clusters larger than two nodes to DRBD®. That gave us the means to implement the concept of quorum and eliminate the old plague of many clusters: the split-brain. The concept is intriguingly simple. A partition of the cluster may modify the data when it […]
