Installing ACS in a VMware Virtual Machine

This chapter describes the system requirements and installation of ACS 5.5 in a VMware virtual machine.

This section contains:

Virtual Machine Requirements

The minimum system requirements for the VMware virtual machine (VM) must be similar to the CSACS-1121 appliance hardware configuration.

Table 10-1 lists the minimum system requirements to install ACS 5.5 on a VMware virtual machine.


Table 10-1 Minimum System Requirements

Requirement Type
Minimum Requirements


2 CPUs (dual CPU, Xeon, Core2 Duo or 2 single CPUs)



Hard Disk

A minimum of 60 GB is required.

Maximum storage is up to 750 GB.

Note ACS partitions the available disk space automatically during the installation process.

Note It is recommended that you allocate the hard disk size to be greater than 500 GB for the secondary instance, which acts as a log collector.

NIC (Network Interface Card)

1 Gb dedicated NIC interface


  • VMware ESXi 5.0
  • VMware ESXi 5.1

Note If you want to upgrade the ACS installed on virtual machine to ACS 5.5, the virtual machine disk size should be greater than or equal to 500 GB.

The disk space management mechanism in ACS 5.5 manages the system automatically and configures the available file volumes on the file system per file type, such as local store, logs, configuration, cache, and so on. The actual file size limits are calculated at the time of installation, based on the hard coded relative disk quota configuration (percent based), using the disk size as an input. However, ACS database logs have a fixed size. ACS 5.5 gets installed with a variable hard disk size between 60 GB and 750 GB, based on the disk size that was chosen while creating the VMware instance. If you want to change the size of the ACS disk after the installation, complete the following procedure:

  • Back up your data.
  • Reimage the ACS application or install a fresh application.
  • Restore the backed up data.

While restoring the backed up data, a warning message is displayed when the backup size or ACS view database size exceeds the corresponding disk quota. However, the restore operation will not be interrupted. The restore operation fails only when the hard limit of /opt partition size is reached.

In ACS 5.5, the log collector server can be installed on a 60 GB disk space. An ACS view log collector node usually requires more space to maintain a database of logs and reports. Therefore, the recommended disk size for the secondary instance, which acts as a log collector server, is 500 GB.

When you allocate 60 GB for the log collector server, the view database gets only 5.6 GB as total disk space. As a result of this, some of the functionalities may not work properly. The functionalities that may be affected are backup, full backup, incremental backup, logging recovery, purge, database compress operation, and so on.

While creating the VMware instances, ensure that the resources allocated for VMware instances with respect to CPU cores, RAM, and disk, are not more than the actual physical resources of the VMware host server. For example, if the VMware host server has a total of 10 CPU cores, then the sum of the allocated CPU cores for all the VMware instances that are created on that server should not exceed 10.

Note In large ACS distributed deployment environments that are hosted on the VM, it is recommended that all VM hosting servers have CPUs from the same vendor.

Note It is recommended that if hyperthreading is enabled on any one of the VMware hosts, it should be enabled on all the VMware hosts that host the ACS VM as part of the same deployment.

Note ACS 5.5 does not get installed over multiple disks (by defining one Logical volume Manager [LVM] disk).

VMware Hardening Requirements

Both the VMware server and the operating system on which the VMware virtual machine is running must be hardened according to the guidelines that are specified by the VMware and operating system vendors.

See the VMware support website for more details. Some helpful links are:


VMware Tools Support

ACS 5.5 supports VMware Tools 9.0.0. The benefits of using VMware Tools in ACS 5.5 are:

  • Improved NIC performance
  • Improved Small Computer System Interface (SCSI) I/O performance
  • Synchronization of guest operating system time with the host time

A new line of text appears, which says Virtual machine detected, configuring VMware Tools when you run the initial Setup Wizard. You can also do the following to check if the VMware Tools are installed:

Click the Summary tab of the virtual machine in the vSphere client. You can see that the text “Running” appears against VMware Tools. This confirms that the VMware Tools are installed and running.

You can use the CLI command show inventory. When you run this CLI, a list appears that shows the NIC driver information. If the VMware Tools are installed, then the driver information is listed as VMware Virtual Ethernet Driver .
