Additional Modules Partition
You can install additional packages, such as the Data Plane API and the WAF, on the virtual appliance or the HAProxy ALOHA 5300 and newer hardware appliances. However, on the virtual appliance, these features require that you mount an additional disk partition to store their files.
To use additional packages on virtual appliances, you must:
Allocate at least 6 GB of RAM to each of your HAProxy ALOHA virtual appliances. This number comes from benchmarking memory usage of the additional packages while taking into account the RAM needed to run other services on the system. Note that insufficient memory may cause HAProxy ALOHA to reboot due to a watchdog process that monitors memory.
Attach a new disk to your HAProxy ALOHA virtual appliances.
The sections below will guide you through attaching a new disk under a VMware® vSphere® hypervisor. Please see your hypervisor documentation if you use another hypervisor.
VMWare vSphere: Attach a new disk
You need to attach to HAProxy ALOHA virtual appliance a new hard drive that will store additional modules.
