Highly Available NFS Storage using LINBIT HA for Kubernetes
While NFS (Network File System) isn’t a new or exciting technology, it is one of the more common storage solutions for Kubernetes clusters that require persistent storage. Particularly, applications or pods requiring shared, network-based, “read write many” (RWX) access to storage in Kubernetes can benefit from the familiar storage solution. LINBIT® supports clients who build […]
The Benefits of High Availability (HA)
This article describes the reasoning behind and the benefits of a high-availability (HA) solution for providing services and applications. This article is intended as a general overview and introduction to HA, with a nontechnical reader in mind. Because you are reading this article on the LINBIT® blog, you will also learn how LINBIT software can […]
Replication Speed and CPU Efficiency Improvements in DRBD 9.3.1
The release of DRBD® 9.3.1 brings with it a “streaming I/O” feature. This feature means that DRBD can allocate compound pages from the kernel as I/O buffers. When applications make large I/O requests or streaming accesses, using compound pages can improve performance because DRBD will use CPU resources more efficiently. Background on DRBD memory allocation […]
Four Claude-Assisted LINBIT Projects & drbd-9.3.1
In the last few weeks, four LINBITers approached me to show me something. In all four cases, it was people not working in development. Two solution architects, one manager, and my contact for security and compliance. And all four presented LINBIT-relevant tools they created using Claude code. I therefore can’t help but notice the trend […]
Cybersecurity & What LINBIT Does
For a long time, when I told people that LINBIT® helps secure data, I would occasionally hear the reply, “You secure data from bad actors, so you are providing something like a firewall.” Then, of course, I replied with an explanation that LINBIT is about data replication and that users mainly want it to protect […]
Backing up or Migrating a Kubernetes Deployment by Using Velero & LINSTOR
Authors: Joel Zhou & Michael Troutman — In a Kubernetes cluster that has persistent storage managed by LINSTOR®, you bring high availability (HA) and data locality features to the persistent data that your applications and services rely on. To complement a running-in-production or enterprise Kubernetes deployment involving persistent data, you will likely want an off-site […]
