Apache CloudStack as a VMware Alternative: A Deep Dive into CloudStack Features Anticipating VMware Migration
The Apache CloudStack Project is observing a significant interest from Cloud Service Providers, who are looking for a VMware alternative after the VMware Broadcom acquisition and the announcement of significant changes in the VMware Partner Connect Program, licensing models and VMware pricing.
How Yellowbrick Data Contributed to Improving LINBIT Open Source Software
One of the reasons that LINBIT® uses an open source licensing model1 for nearly all of the software that LINBIT developers create is because the open source model encourages collaboration and engagement with users, in a way that closed source software does not. With open source software, the software code is freely available for anyone […]
A Risky Move for Broadcom + Another Win for Open Source
Happy New Year! We will rock 2024, improving high availability and high-performance data storage on Linux. In the coming year, I look forward to doing more work on the RDMA code in DRBD, seeing LINSTOR reach 2.0, bringing an overhauled API, and providing better interactive feedback for long-running operations. I have more plans and projects […]
Using VDO with DRBD on RHEL 9
This blog will provide installation and configuration instructions for implementing Red Hat’s Virtual Data Optimizer (VDO) and LINBIT®’s DRBD®. VDO is a virtual block device driver that provides inline deduplication, compression, and thin provisioning for block storage in Linux. VDO operates within the Linux kernel and is managed by LVM. DRBD is a virtual block […]
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 […]
