Thoughts on Red Hat’s Source Repository Changes
Recently, Red Hat’s change in how they distribute the source code of their distro caught my (and the open source world’s) attention. The Register has an excellent historical summary, and there is an article by Bradley M. Kuhn discussing how this move aligns with the GPL. A few days later, a follow-up blog post by Mike McGrath expressed that he sees no […]
The Benefits of Hyperconverged Infrastructure
Hyperconverged infrastructure (HCI) is a computer systems architecture that abstracts the compute, storage, and networking components of the architecture by using their software-defined functional equivalents and is run from a single system, rather than across multiple systems. The LINBIT® software-defined storage (SDS) solution is often used in HCI to provide, as you might guess, the […]
DRBD 9.2 Updates
The eight-week cadence brings the new DRBD releases 9.1.15 and 9.2.2. The two releases contain roughly the same bug fixes. What these bug fixes have in common is that the underlying bugs trigger very seldom. We found one while using drbd-9.2 in our internal virtualization cluster for our lab infrastructure. Via the ‘eat your own dog […]
An Introduction to LINBIT SDS Management
As part of ongoing efforts to make LINBIT® software-defined storage (SDS) solutions better understood and more widely used, the LINSTOR® Users Guide has undergone a major change. The guide now has an introductory chapter that explains how the LINSTOR component of LINBIT SDS works and deploys storage. It also explains important concepts and terms that are used […]
LINBIT SDS is now on Xinnor xiRAID
LINBIT SDS and xiRAID have proven to work exceptionally well together, and with LINBIT SDS now on Xinnor xiRAID, I wanted to cover the subject on our blog. Linux is not short of software RAID options: Xinnor is a company from Israel that has spent a long time researching and optimizing software RAID. Their solution […]
STAC Summit, Software Updates, & Testimonials
I recently spoke at STAC Summit in London and Rene Peinthor, a LINBIT developer, was also in London for his talk at the CloudStack European User Group. A busy time all around for the team! We recently published ‘Kubernetes High Availability for Stateful Workloads,’ showing how LINSTOR’s HA Controller for Kubernetes can lower the recovery time of […]
PHOENIX MEDIA Switches Out Competitor with LINBIT SDS for Kubernetes
High performance will always be a core value of any of our software. We recently shared some exciting performance results from our collaboration with Ampere, breaking our IOPS record again from 14.9 to 25.5 mio IOPS. On the subject of performance, PHOENIX MEDIA decided to integrate LINBIT SDS in its operations with Rancher, the Kubernetes […]
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 […]
Speed of Light Media Replaces Ceph with DRBD for Its Cloud Needs
Speed of Light Media has been ecstatic with their decision to replace CEPH in favor of DRBD®. According to Robert Isaacs, the tech-savvy founder and CEO of Speed of Light Media, the decision to make the switch was prompted by careful evaluation and that LINBIT®’s solution comprises clear building blocks, with a clean separation of […]
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 […]
