Virtual machine settings

When setting up a virtual appliance, you need to configure settings for the virtual machine you want to use as the platform for the appliance software.

Table 1: Virtual machine settings
Option Definition
Configuration type Typical | Advanced (recommended)
Installation mode Install from disk | ISO image (required) | Install later
Operating system Linux 64 bit, version 2.6
Memory

32 GB (recommended, for more information, see Verify the requirements)

Note:

Starting with version 4.1, VMware ESXi, which is one of the supported VMware types for a virtual Web Gateway appliance, includes some optimizations known as NUMA optimizations.

A host system for virtual machines that runs this VMware is also referred to as a NUMA node. Memory must then be allotted to a virtual machine in relation to the memory that is available on a NUMA node, otherwise you might experience a severe impact on performance.

For example, if you set up three virtual machines on one NUMA node and configure the same number of processors (also known as CPU cores) for each virtual machine, you should not allot more than one third of the memory that is available on the NUMA node to each virtual machine.

Best results are achieved, however, if you run one virtual machine on one NUMA node.

Make sure that you also reserve a certain amount of memory for the NUMA node (the host system).

Hard-disk space 500 GB (recommended, for more information, see Verify the requirements)
Number of processors

1 | 2 | 4 (recommended, for more information, see Verify the requirements) | ...

The number of processors (also known as CPU cores) that are provided for selection depends on the equipment of the host system that is used for setting up the virtual appliance.

Note:

When virtual machines are set up on a host system that runs ESXi VMware, version 4.1 or later, with NUMA optimizations, see also under Memory, CPU cores should be configured in relation to what is allowed on a NUMA node (a host system).

The number of CPU cores that you configure for a virtual machine should be multiples or divisors of the number of CPU cores that fit in with the size of a NUMA node.

For example, if the size of a NUMA node is sufficient for running six CPU cores, you should configure virtual machines with two, three, or six cores (if you are only using one node), or with 12, 18, 24, and so on (if you are using multiple nodes).

Best results are achieved, however, if you run one virtual machine on one NUMA node.

Network connection mode Bridged (recommended) | NAT | ...
CD/DVD drive with assigned ISO image <drive name>/<name of the ISO image>
Network interface card type E1000 | VMXNET 3 (recommended)

SCSI controller (for some ESX versions)

BusLogic SCSI (not supported in a 64-bit environment) | LSI Logic Parallel (default) | LSI Logic SAS | VMware PV SCSI (recommended)
