Supported Virtual Servers

Avaya supports the IP Office virtual machine on the following virtual server platforms:

• VMware vSphere: The vSphere support is:

  • Supported with VMware vSphere ESXi 7.0 and 8.0.

  • Support includes the Standard, Enterprise and Enterprise Plus variants. Also support for Essentials Kit and Essentials Plus Kit variants where available.

Supported VMware Virtual Server Features

• vCenter: VMware vCenter server, is the centralized management tool for the vSphere suite. It allows the management of multiple host servers and virtual machines on different hosts through a single console application.

• vMotion: vMotion allows you to move an existing virtual machine from one virtual server platform to another with minimal interruption to the operation of the virtual machine. For example, this may be necessary if the existing server platform resources become exhausted. see vMotion requirements.

• Snapshot: The virtual machine must be powered off before taking or deleting a snapshot. Note that running a virtual machine with snapshots degrades its performance. Similarly, deleting snapshots can take some time to complete and can impact performance.

  The virtual machines disk size cannot be changed if any snapshot is taken from the virtual machine. Any existing snapshots must be deleted first.

• OVA Deployment

• Soft Power Off

• High Availability: Enables the automatic re-establishment of the virtual machine on a new host server during a failure on or of the original host. See High availability.

• VMware Tools: Note however that an IP Office specific version of VMware tools is included as part of the IP Office OVA. See VMware tools.

vSphere Clients

Traditional host management used the vSphere desktop client installed on a client PC. For vSphere 5.0 onwards, VMware introduced the vSphere web client. The vSphere desktop client is still supported, however new features released with vSphere 5.1 and higher are only managed using the vSphere web client.

Also, using vSphere desktop client to connect to the ESXi 5.5 host and deploy the OVA will fail. When the 5.x ESXi host version is managed by a virtual center, the vSphere desktop client's management capabilities are restricted.
