vCenter Performance Tuning

This section describes performance tuning steps for the vCenter that hosts your ESXi server.

• Installing and compiling VMware PowerCLI XML serializers
• Configuring the SA Agent
• Managing the ESXi server
• Downloading the ESXi compliance library

Installing and compiling VMware PowerCLI XML serializers

Another prerequisite for running ESXi Servers is to set up the XML serializers.

To set up the XML serializers:

1. Make sure an SA Agent is installed on the vCenter.
2. Set the PowerShell execution policy.
3. Access the .PS1 files in SA at Library > Scripts > Windows.
4. Run the files from SA.

Configuring the SA Agent

If you see the following error: Error from remote (3056): connect to Agent failed (Connection refused) in the agent service configuration file located at:

C:\Program Files\Common Files\Opsware\etc\agent\ agentservice.args

increase the value of the following parameter (the default value is 20):

cogbot.max_concurrent_shell_connections: 50 

Managing the ESXi server

See the "Virtualization management" in the SA 10.51 Use section for information on how to manage your ESXi servers through a vCenter.

Downloading the ESXi compliance library

Access the HPE Live Network site (https://hpln.hpe.com) to download the ESXi Compliance Library. The Compliance Library Policies include an array of user-customizable checks to audit and remediate commonly-used objects on platforms, such as Local Security Settings on Windows or configurations on Linux. Regulatory Policies provide pre-defined values for audit and remediation according to guidelines such as PCI, SOX, or CIS.

The Compliance Library Policies contain user-customizable checks to audit and remediate commonly-audited objects on all supported SA platforms, and comprise of a set of items that Audit and Remediation dynamic policies are based on. For example, you can the define different audits to ensure a subset of managed servers have a minimum password length of 8, while a different set have a minimum password length of 10. Where possible, checks have remediation enabled to allow users to bring managed servers into custom-defined compliance.

The ESXi compliance content is part of the cc_library stream.
