Oracle Linux 8.10, 9.4, 9.6 (Unbreakable Enterprise Kernel) (x64)
Oracle Linux 8.10, 9.4, 9.6 (Red Hat Compatible Kernel) (x64)

Network configuration

The Analyzer detail view server supports IPv4 only.

Virtualization software

VMware vSphere Hypervisor (VMware ESXi) 8.0, 8.0 update 1, 8.0 update 2, or 8.0 update 3
2022 Hyper-V
Linux KVM

Note:

VMware vSphere HA is available.

Java version

Amazon corretto 17
Oracle JDK 17

Amazon Corretto 17 is bundled with Analyzer detail view server. If the default OS Java (the Java that is specified as /usr/bin/java by the alternatives command) is not Oracle JDK 17, Amazon Corretto 17 is installed and is set as the default OS Java.

If you want to use Oracle JDK 17, install it in advance, and specify it as the default OS Java. If you are using a version earlier than the supported versions of Oracle JDK 17, upgrade it in advance.

Note:

For details on Java versions, see the Release Notes.
You can change the Java version to Oracle JDK 17 after you install Analyzer detail view server. For details, see the Release Notes.

Prerequisite RPM packages

Install the following RPM packages before installing the Analyzer detail view server. You can check which RPM packages are missing by running the precheck tool (analytics_precheck.sh) provided by Ops Center Analyzer.

Hardware requirements

To complete the installation, the disk usage must be less than 95%. You must install the Analyzer detail view server on a physical disk. When you run the analytics_install.sh command, do not install the Analyzer detail view server on the same disk where the operating system is installed. Do not create these directories on a Network File System (NFS) partition. The Analyzer detail view server retrieves the partition details and checks the free disk space. If any of the listed directories are located on the same partition, the required disk space is the sum of the disk space of the directories. If Analyzer server and Analyzer detail view server are installed on the same host, use these values: Small: 7, Medium: 8, Large: 8 To monitor hypervisors or switches in addition to storage systems, you must increase the number of resources based on the system scale. If you want to monitor both hypervisors and switches, just use the larger of the two resource requirements. For details about the default installation directory, see Default installation directory. Do not include any symbolic links in the installation directory. Note: Values are calculated based on a Hitachi Enterprise Storage system.
