Vmware vSphere PSC

1 Introduction

VMware, Inc. provide cloud and virtualization software and services. Platform Services Controller (PSC) is a component of the VMware Cloud Infrastructure Suite. PSC deals with identity management for administrators and applications that interact with the vSphere platform.

PSC provides one appliance- or Windows-based virtual machine platform to systems administrators for centralized management of these common infrastructure services. It is a distributed service that automatically replicates information such as licenses, permissions and roles to other PSC instances. The maximum number of PSCs per vSphere domain is set at eight. High-availability for PSCs is achieved through local load-balancing technologies, though only four PSCs can reside behind a load balancer. PSCs are also latency sensitive and can only tolerate up to five minutes of time skew between PSC nodes.

In vSphere 6, the following components are installed in PSC:

  •     VMware Appliance Management Service (only in appliance-based PSC)
  •     VMware License Service
  •     VMware Component Manager
  •     VMware Identity Management Service
  •     VMware HTTP Reverse Proxy
  •     VMware Service Control Agent
  •     VMware Security Token Service
  •     VMware Common Logging Service
  •     VMware Syslog Health Service
  •     VMware Authentication Framework
  •     VMware Certificate Service
  •     VMware Directory Service

1.1 Document Purpose

The purpose of this document is to explain how to configure the LoadMaster to optimize PSC.

1.2 Intended Audience

This document is intended to be read by anyone who is interested in configuring the LoadMaster to optimize the new features in PSC 6.X.

2 PSC Template

Kemp has developed a template containing our recommended settings for PSC. You can install this template on the LoadMaster and use it when creating Virtual Services. Using a template automatically populates the settings in the Virtual Services, which is quicker and easier than manually configuring each Virtual Service. If needed, you can make changes to any of the Virtual Service settings after using the template.

Download released templates from the Templates section on the Kemp documentation page: http://kemptechnologies.com/documentation/.

For more information and steps on how to import and use templates, refer to the Virtual Services and Templates, Feature Description.

For steps on how to manually add and configure each of the Virtual Services, refer to the Configure the LoadMaster section.

4 Configure the LoadMaster

The deployed VMware Systems environment determines which of the following setups is used.

4.1 Enable Subnet Originating Requests Globally

It is best practice to enable the Subnet Originating Requests option globally.

In a one-armed setup (where the Virtual Service and Real Servers are on the same network/subnet), Subnet Originating Requests is usually not needed. However, enabling Subnet Originating Requests should not affect the routing in a one-armed setup.

In a two-armed setup where the Virtual Service is on network/subnet A, for example, and the Real Servers are on network B - Subnet Originating Requests should be enabled on LoadMasters with firmware version 7.1-16 and above.

When Subnet Originating Requests is enabled, the LoadMaster routes traffic so that the Real Server sees traffic arriving from the LoadMaster interface that is in that network/subnet.

When Subnet Originating Requests is enabled globally, it is automatically enabled on all Virtual Services. If the Subnet Originating Requests option is disabled globally, you can select whether or not to enable Subnet Originating Requests on a per-Virtual Service basis.

To enable Subnet Originating Requests globally, follow the steps below:

1. In the main menu of the LoadMaster WUI, go to System Configuration > Miscellaneous Options > Network Options.

2. Select the Subnet Originating Requests check box.

4.2 Enable Check Persist Globally

It is recommended that you change the Always Check Persist option to Yes - Accept Changes. Use the following steps:

1. Go to System Configuration > Miscellaneous Options > L7 Configuration.

2. Click the Always Check Persist dropdown arrow and select Yes - Accept Changes.
