HAProxy Enterprise Documentation 13.0

Prerequisites

You can use additional packages on ALOHA 5300 and ALOHA 5350 hardware appliances.

To use additional packages on virtual appliances, you must:

  • Allocate at least 6 GB of RAM to each of your 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 the ALOHA to reboot due to a watchdog process that monitors memory.

  • Attach a new disk to your 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 the ALOHA virtual appliance a new hard drive that will store additional modules.

  1. Log in to your VMware® vSphere® Client, then power off your ALOHA Virtual Appliance.

  2. Select Actions > Edit Setting.

    The Virtual Hardware tab displays.

  3. Select Add New Device > Hard Disk.

  4. Create a new 30 GB or larger disk in the New Hard Disk field.

  5. Power on your ALOHA Virtual Appliance.

Mount a new partition

You need to edit the ALOHA configuration so that the new /dev/sdb1 partition is mounted on the /app mountpoint at startup.

  1. Log in to your ALOHA WUI as an administrator.

    For example, log in to http://172.16.24.237:4444/.
