Considerations for deploying ONTAP tools
Before you deploy ONTAP tools for VMware vSphere, it is good practice to plan your deployment and decide how you want to configure ONTAP tools in your environment.
The following table presents an overview of what you should consider before you deploy ONTAP tools.
Considerations |
Description |
First-time deployment of ONTAP tools |
The deployment of the ONTAP tools automatically installs the VSC features. |
Upgrading from an existing deployment of VSC |
The upgrade procedure from an existing deployment of VSC to ONTAP tools depends on the version of VSC, and whether you have deployed ONTAP tools. The deployment workflows and upgrade section has more information. Best practices before an upgrade:
|
Regenerating an SSL certificate for VSC |
The SSL certificate is automatically generated when you deploy the ONTAP tools. You might have to regenerate the SSL certificate to create a site-specific certificate. |
Setting ESXi server values |
Although most of your ESXi server values are set by default, it is a good practice to check the values. These values are based on internal testing. Depending on your environment, you might have to change some of the values to improve performance. |
Guest operating system timeout values |
The guest operating system (guest OS) timeout scripts set the SCSI I/O timeout values for supported Linux, Solaris, and Windows guest operating systems to provide correct failover behavior. |
The following table presents an overview of what you require to configure the ONTAP tools.
Considerations |
Description |
Requirements of role-based access control (RBAC) |
VSC supports both vCenter Server RBAC and ONTAP RBAC. The account used to register VSC to vCenter Server ( If your company requires that you restrict access to vSphere objects, you can create and assign standard VSC roles to users to meet the vCenter Server requirements. You can create the recommended ONTAP roles by using ONTAP System Manager using the JSON file provided with the ONTAP tools. If a user attempts to perform a task without the correct privileges and permissions, the task options are grayed out. |
ONTAP version |
Your storage systems must be running ONTAP 9.3, 9.5, 9.6, 9.7, 9.8P1 or later. |
Storage capability profiles |
To use storage capability profiles or to set up alarms, you must enable VASA Provider for ONTAP. After you enable VASA Provider, you can configure VMware Virtual Volumes (vVols) datastores, and you can create and manage storage capability profiles and alarms. The alarms warn you when a volume or an aggregate is at nearly full capacity or when a datastore is no longer in compliance with the associated storage capability profile. |
