Disaster Recovery Is Not a Technology, It’s a Plan
Disaster recovery (DR) is often perceived as a purely technological solution implemented within storage or virtualization environments, thanks to aggressive marketing by software vendors. However, DR involves more than software alone. It’s a comprehensive strategy that integrates diverse technologies, requiring businesses to recognize this broader perspective to mitigate potential risks and ensure effective recovery. Challenging […]
LINBIT Software Used In an Academic Research Clustering Project
We at LINBIT® are pleased to learn about a collaborative research project between 45drives, a data storage solutions company built on open source, and Nova Scotia Community College (NSCC) in Canada. The college has chosen the top five students in its Systems Management and Security program to investigate using DRBD® and LINSTOR® as a high availability block storage […]
Using the DRBD Quorum Feature as an Alternative to Fencing in a Pacemaker Cluster
Implementing fencing is a way to ensure the consistency of your replicated data by avoiding “split-brain” scenarios. When communication between cluster nodes breaks, fencing prevents the data from diverging among your data replicas. DRBD® and Pacemaker each have their own implementations of fencing. A Pacemaker fencing implementation usually involves a hardware outlay. When using software-based […]
Filling the Gap: LINBIT SDS in Amazon EKS
Update: The full technical document described in this blog post has been updated to version 8.2 on 2024-04-06 to include enhancements made to the LINSTOR Operator’s monitoring and alerting capabilities. 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 […]
Discussion with Our Partners after the VMware News
We held our recent Community Meeting on March 14th, and decided to try something new. We gave our developers a break from the spotlight to invite partners from ShapeBlue, OpenNebula, and Vates to discuss the fallout from the recent VMware/Broadcom news. We posed the question of whether or not LINBIT’s partners, who offer open-source virtualization solutions, have […]
Enabling Long Distance Replication for Disaster Recovery Using LINSTOR & DRBD Proxy
In this video Matt Kereczman from LINBIT® combines components of LINBIT SDS and LINBIT to demonstrate extending an existing LINSTOR® managed DRBD® volume to a disaster recovery node, located in a geographically-separated datacenter via LINSTOR and DRBD proxy. Watch the video: He’s already created a LINSTOR cluster on four nodes: linstor-a, linstor-b, linstor-c and linstor-dr. […]
The Stretched Cluster Disaster Recovery Strategy
My colleague, Yusuf Yildiz, a solutions architect here at LINBIT® strongly believes disaster recovery (DR) should be thought of as a plan, rather than a solution. It is impossible for there to be a one-size-fits-all DR solution that works for everyone. Each organization needing DR will have different values that it places on different services […]
NAS High Availability Using a Synology NAS Appliance & LINBIT Software
Recently I came across Synology’s spin on high availability. After perusing through their documentation I noticed an all too familiar protocol: DRBD®. Recognizing this software and having a recent desire to tinker a bit, I picked up two DS224+ hardware storage appliances, one of their least expensive models. LINBIT® is no stranger to assisting companies implement high availability […]
Highly Available SCST & LIO iSCSI Clustering How-To Guide Update & Comparison
Companion Tech Guide Updated using Community Feedback on 3/21/24 LINBIT®️ has been building and supporting Highly Available (HA) iSCSI clusters using DRBD®️ and Pacemaker for over a decade. We recently updated our HA iSCSI how-to guides for RHEL 8 and RHEL 9 to include instructions for both the Linux-IO (LIO) and SCSI Target Subsystem for […]
Migrating Manually Created DRBD Resources to LINSTOR Software-Defined Storage
DRBD® has been a long-standing and proven solution for creating high-availability (HA) storage. LINSTOR®, the LINBIT®-developed software-defined storage (SDS) solution, is a relatively newer offering. You can use LINSTOR to make managing storage easier, and it pairs seamlessly with DRBD behind the scenes. LINSTOR also integrates with many platforms such as Kubernetes, CloudStack, Docker, OpenNebula, […]
