Comparing LINSTOR & Ceph Storage Clusters
Over the many years that I’ve worked for LINBIT®, I cannot tell you how many times I’ve been asked, “How does a LINSTOR® (or DRBD®) cluster compare to a Ceph storage cluster?” Hopefully I can help answer that question in this blog post for anyone who might Google this in the future. My short answer could […]
Using a Cluster Resource Manager and DRBD to Minimize System Maintenance Downtime
Besides helping to make your applications and services highly available, one of the lesser known benefits of using DRBD® is using it to help minimize downtime when you are doing system maintenance. Another blog post gives some background and an example workflow for this use case. For simplicity, that blog post only provides an overview of technical […]
Managing Highly Available NVMe-oF, iSCSI, and NFS Data Stores with LINBIT VSAN
LINBIT VSAN is a turnkey SDS appliance that manages highly available NVMe-oF, iSCSI, and NFS data stores. It uses LINBIT® software from LINBIT SDS and LINBIT HA to offer a unified storage cluster management experience with a simple, intuitive GUI. LINBIT VSAN is designed for small to medium-sized VMware deployments but you can use it […]
The Impact of Network Latency on Write Performance When Using DRBD
Keeping write latency low and throughput high is fundamental in designing or implementing storage systems. With standalone servers running applications using direct attached storage, this is a relatively straightforward task that doesn’t involve much more than reviewing manufacturer spec sheets before ordering the hardware. With network attached storage, such as NAS or SAN storage, the […]
Setting Up LINBIT SDS with OpenNebula for Resilient & Flexible Storage
Authors: Michael Troutman & Rene Peinthor — This post will guide you through integrating LINBIT SDS (LINSTOR® and DRBD®) with OpenNebula, to provide fast, scalable, and highly available storage for your virtual machine (VM) images. After completing the integration, you will be able to easily live-migrate VMs between OpenNebula nodes, and have data redundancy, so […]
New Version of LINBIT VSAN
I recently returned from the STAC Summit, where I presented ‘Fast Data Replication with DRBD over RDMA/RoCE/IB/verbs’ as part of the ‘Innovation Roundup.’ The challenge at STAC is that every vendor presentation gets a 5-minute time slot. I was quite relieved after 4:20 that I said everything I wanted to say without feeling rushed. I saw […]
Minimize Downtime During System Maintenance
System maintenance, whether you plan for it or do it in response to failure, is a necessary part of managing infrastructure. Everyone hopes to only have to do planned-for system maintenance. The reality is that with so many pieces of a system puzzle, you also have to plan for failures. Regularly maintaining your systems, just […]
The Benefits of Buying Support for Open Source Software
One of the enticing things about open source software is its almost universal price tag: free. Another enticement is your ability to start testing and using an open source solution, usually without going through barriers, such as creating an account on a platform website, or downloading software from a proprietary source and possibly exposing yourself […]
Upcoming Events & Software Updates
In the coming month, there are two events that our team will be attending. The first event is STAC (Strategic Technology Analysis Center). STAC’s research helps players in the finance industry discover and assess technology. LINBIT team members have been to the spring event before and are looking forward to our second appearance at STAC on […]
Encrypted Replication With DRBD
With the arrival of DRBD® 9.2.6, replication traffic can now be encrypted by the Linux kernel. DRBD is now able to use in-kernel TLS acceleration (kTLS), which has been fully implemented since the release of Linux kernel version 4.17. LINBIT® developer Moritz Wanzenböck initially demoed the new feature during our recent community meeting. While it has […]
