Avaya Analytics™ supports thin provisioning of disk storage in VMware for all agent configurations. Though this document specifies the required disk storage space for each agent configuration, you do not have to provision the entire disk space on day 1. You can add space as and when needed. No maintenance window is required.
Warning:
You must actively manage your VMware disk space and add more space before the application runs out of space.
Insufficient disk space provided to the system when operating with thin provisioning can result in disk write errors in the logs and data loss. Avaya bears no responsibility for errors and data loss.
To ensure efficient thin provisioning, do the following:
Provision additional disk space whenever the remaining disk space is less than 0.25 TB, assuming that you can provision additional storage within an hour or less. You are accountable for the time required to provision additional disk storage before the system reaches its current limit.
When the datastore capacity does not initially meet the requisite footprint, the minimum storage requirement for a deployment requires the datastore to be at least the size of disk 2 on cluster node 1 or 2.
You can find this storage size in the spreadsheet on the Deployment Properties tab in the Footprint Summary table under Disk Storage Requirements for Cluster Node 1 or 2.
Adding additional disk space is a standard VMware operation.
