https://www.youtube.com/watch?v=DdlIhfU2VAU In this video (English subtitled), I demonstrate the aggregate performance of a 4-node Lustre cluster (3 OSS + 1 MDS/MGS) and the block volumes provided by Oracle OCI. Of course, this is a functionality test and not a production POC. In addition to understanding and observing the aggregate performance that only 3 active OSS nodes can deliver, I wanted to test 2 failover systems between OSS1 and OSS2 nodes (OSS3 is unpaired and works without failover). 1 - The…

In today’s high-performance computing (HPC) landscape, storage solutions that offer speed, scalability, and reliability are essential. Lustre, an open-source parallel file system, is a popular choice for HPC environments due to its capacity to handle large datasets and intensive workloads. When deploying Lustre on Oracle Cloud Infrastructure (OCI), achieving an optimized design that balances performance with cost-efficiency requires careful planning. Let's explore key Lustre infrastructure design patterns tailored for OCI, focusing on strategies to meet diverse storage needs and performance…

How to setup a linux Virtual IP Failover (IP Floating) on Oracle OCI managed by pacemaker

Introduction In many environments, it is still essential to use infrastructures with an active/passive Linux cluster, which require the use of IP floating. In cloud infrastructures, the secondary IP address must be managed not only by the operating system but also by the cloud infrastructure. In this tutorial, we will see how the IP floating of a Linux cluster can be managed as an integrated resource by Pacemaker, in a simple manner and without custom code, as seen in several…
