VM ESXi requirements The VM must meet the following minimum requirements. Processor — 8 cores or higher, depending on model, 64-bit, Dual Core2/Nehalem or higher or AMD Dual Athlon64/Dual Opteron64 or later RAM — 4 GB minimum (depends on the model) Disk — 250 minimum (depends on the model) ESXI — 5.0 or later You can select the hard disk requirement needs for your server. But, the VM requirement depends on the model of the device (at least 250 GB). If you don't have a minimum of 250 GB available, you receive an error when deploying the VM. The VM uses many features that require CPU and RAM. If the ESXi environment shares the CPU or RAM requirements with other VMs, the performance of the VM is impacted. McAfee recommends setting the provisioning option to Thick. Stripe the storage drive If the model is more than 250 GB and needs the 256 MB to 2 MB setting, stripe the virtual machine's storage drive. The VM uses many features that require CPU and RAM. If the ESXi environment shares the CPU/RAM requirements with other VMs, the performance of the VM is impacted. Plan CPU and RAM needs within the requirements. Install the virtual machine Once you install and key a VM, it mimics normal ESM operation. Configure the virtual machine Once you have installed the VM, configure the network interface. Key the VM device You must key the device to establish a link between the device and the ESM.
