Isilon InsightIQ 4.1.4.x Installation Guide

Local datastore

If InsightIQ is installed on a virtual machine, InsightIQ stores the datastore locally on a virtual hard drive that is included on the InsightIQ virtual machine. If InsightIQ is installed on a Linux system, InsightIQ stores the datastore on the local hard drive.

If you want to store the datastore on a local drive, the drive must meet the following requirements:

• Ensure that the local drive contains at least 70 GB of free disk space.
• The datastore location cannot contain an existing InsightIQ datastore.

Isilon OneFS datastore

If you want to store the datastore on an Isilon OneFS system, the cluster must meet the following requirements:

• Ensure that the directory contains at least 70 GB of free disk space.
• The datastore location cannot contain an existing InsightIQ datastore.
• Verify that the Isilon OneFS operating system supports the version of InsightIQ to be installed.
• Verify that the server includes a correctly configured NFS export rule. The export rule must export the datastore path, and map the root user on the InsightIQ server to the user account that owns the export on the NFS server.
• Enable read and write access to the export. Isilon OneFS ships with a default NFS export rule for the /ifs directory that you can use for InsightIQ. If that default NFS export has been modified or deleted, create NFS export rule that allows write access for InsightIQ.

Other NFS datastore

If you want to store the datastore on a different NFS-based server the NFS server must meet the following requirements:

• Ensure that the directory contains at least 70 GB of free disk space.
• The datastore location cannot contain an existing InsightIQ datastore.
• Verify that the server includes a correctly configured NFS export rule. The export rule must export the datastore path, and map the root user on the InsightIQ server to the user account that owns the export on the NFS server.
• Enable read and write access to the export rule. This configuration allows InsightIQ to mount the server and create the necessary directories and files on the server.
• If you want to connect to an NFS datastore over IPv6, confirm that the IPv6 addresses are configured for both InsightIQ and the NFS server.

Additional information on datastore disk space

An adequate amount of disk space must be available for InsightIQ to store data. It is recommended that you have at least 70 GB of free disk space, but the amount of data that your specific InsightIQ datastore requires really depends on the number of nodes that are monitored and the length of time that you want InsightIQ to retain data.

It is recommended that you increase the size of the InsightIQ datastore by 2 GB per node for each month of retained data.

Use the following equation to calculate the minimum size of your specific datastore:

<minimum_datastore_size_in_GB> = 2*<number_of_nodes>*<number_of_months> + 10
