OpenShift Container Storage 4 and logging with Elasticsearch and Cluster Logging Operators

May 7, 2020Karan Singh
Red Hat OpenShift Container Platform cluster administrators can deploy cluster logging using a few CLI commands and the OpenShift Container Platform web console to install the Elasticsearch Operator and Cluster Logging Operator. The cluster logging components are based upon Elasticsearch, Fluentd, and Kibana (EFK). The collector, Fluentd, is deployed to each node in the OpenShift Container Platform cluster. It collects node and container logs and writes them to Elasticsearch (ES)…read full post

Scaling Ceph to a billion objects and beyond

February 13, 2020Karan Singh
This is the sixth in Red Hat Ceph object storage performance series. In this post we will take a deep dive and learn how we scale tested Ceph with more than one billion objects, and share the performance secrets we discovered in the process. To better understand the performance results shown in this post, we recommend reviewing the first blog , where we detailed the lab environment, performance toolkit, and methodology used…read full post

Comparing Red Hat Ceph Storage 3.3 BlueStore/Beast performance with Red Hat Ceph Storage 2.0 Filestore/Civetweb

December 5, 2019Karan Singh
This post is the sequel to the object storage performance testing we did two years back based on Red Hat Ceph Storage 2.0 FileStore OSD backend and Civetweb RGW frontend. In this post, we will compare the performance of the latest available (at the time of writing) Ceph Storage i.e. version 3.3 (BlueStore OSD backend & Beast RGW frontend) with Ceph Storage 2.0 version (mid-2017) (FileStore OSD backend & Civetweb RGW frontend)…read full post

Achieving maximum performance from a fixed size Ceph object storage cluster

October 30, 2019Karan Singh
We have tested a variety of configurations, object sizes, and client worker counts in order to maximize the throughput of a seven node Ceph cluster for small and large object workloads. As detailed in the first post the Ceph cluster was built using a single OSD (Object Storage Device) configured per HDD, having a total of 112 OSDs per Ceph cluster. In this post, we will understand the top-line performance for different object sizes and workloads…read full post

Red Hat Ceph Storage RGW deployment strategies and sizing guidance

October 22, 2019Karan Singh
Starting in Red Hat Ceph Storage 3.0, Red Hat added support for Containerized Storage Daemons (CSD) which allows the software-defined storage components (Ceph MON, OSD, MGR, RGW, etc) to run within containers. CSD avoids the need to have dedicated nodes for storage services thus reducing both CAPEX and OPEX by co-located storage containerized daemons. …read full post

Red Hat Ceph object store on Dell EMC servers (Part 1)

October 10, 2019Karan Singh
Organizations are increasingly being tasked with managing billions of files and tens to hundreds of petabytes of data. Object storage is well suited to these challenges, both in the public cloud and on-premise. Organizations need to understand how to best configure and deploy software, hardware, and network components to serve a diverse range of data intensive workloads. …read full post

Red Hat Ceph Storage 3.3 BlueStore compression performance

September 25, 2019Karan Singh
With the BlueStore OSD backend, Red Hat Ceph Storage  gained a new capability known as "on-the-fly data compression" that helps save disk space. Compression can be enabled or disabled on each Ceph pool created on BlueStore OSDs. In addition to this, using the Ceph CLI the compression algorithm and mode can be changed anytime, regardless of whether the pool contains data or not. In this blog we will take a deep dive into BlueStore’s compression mechanism and understand its impact on performance…read full post
