Summary: [Docs] Add a Production page under Getting Started
Key: HDDS-13378
URL: https://issues.apache.org/jira/browse/HDDS-13378
Project: Apache Ozone
Issue Type: Task
Components: documentation
Reporter: Wei-Chiu Chuang
Add a page to list the requirements and best practices of a successful
production deployment:
h1. Requirements
1. System requirements.
- Linux. Red Hat 8 / Rocky 8 or above, Ubuntu and SUSE are recommended.
- JDK 8 or above.
- Chrony or ntpd, for time synchronization.
2. High performance storage devices.
- SAS SSD or NVMe SSD are highly recommended for metadata (RocksDB and Ratis
directory)
- Hard disks are fine for DataNode data storage, but should not be used for
metadata.
- Use direct-attached storage. Do not use NAS or SAN.
3. Security. Optional but highly recommended.
- Kerberos environment, including KDC.
h1. Configurations
1. Linux kernel
* Make sure the Linux kernel scaling driver is in performance mode, not
powersave mode.
* Disable Transparent Hugepage.
* Disable SELinux.
* Set vm.swappiness=1.
2. Local file system
* Disable LVM for data drives.
* Use ext4 or xfs.
* Mount drives with noatime option; mount with discard option for SSD.
3. Ozone configurations
* Install Prometheus, Grafana for monitoring.
* Increase number of write pipelines allowed in the cluster:
ozone.scm.datanode.pipeline.limit and ozone.scm.ec.pipeline.minimum
* Configure sufficient heap size for OM, SCM, Recon, Datanode, S3G and HttpFs
