Avaya IP Office Server Edition Server Requirements

The IP Office OVA installs the following default virtual machine.

  • CPU: 4 vCPU
  • RAM: 8000MB
  • Hard Disk: 100GB
  • Network Ports: Dual Gigabit

After deployment of a virtual machine, you can optimize the resources allocated to meet the actual requirements of the virtual machine. For example, if the virtual machine will only support 50 users, you can reduce the allocated processor and RAM memory. This allows for the best use of the overall resources provided by the virtual server platform.

The tables below shows the tested and supported profile values for different IP Office virtual machine usages.

Profiling Other Virtual Machines

It is in customers best interest and in vSphere administrator best practices to monitor resource utilization of the virtual machines running in their infrastructure. We strongly encourage the customers to profile not only our virtual machines but others they might be running on their ESXi servers to precisely fine-tune hardware resources that are allocated to the virtual machines. This will improve performance by allocating resources where they are needed and optimize the use of their virtual infrastructure.

 

Restrictions

 

  • Network Ports
  • You must configure all IP Office virtual machines with two Ethernet ports. If using vMotion, additional network port requirement apply. See vMotion Considerations.

 

  • Hard Disk
  • Regardless of the IP Office virtual machine's role, it requires 100GB of allocated hard drive space. However, if required additional hard disk space can be added. See Adjusting the Disk Space.

 

  • Multiple Virtual Servers and Disk Storage Access Speed Requirements (IOPS/30 per server)
  • To maintain acceptable performance the number of virtual machines that runs on an ESXi host should not exceed the IOPS (Input/Output Operations per Second) of the disk storage divided by 30. To compute how many IOPS your storage configuration produce you should know the hard disk type, RAID configuration, number of drives. For example: A 10K SAS disk has 150 IOPS available which generates an acceptable performance for 5 virtual machines.

  • Multiple IP Office Servers (Virtual and or Non-Virtual)
  • If deploying both a primary and secondary then the hardware resources assigned to each must consider the resiliency scenario when users re-register from one server (virtual machine) to the other. It is recommended that the primary and secondary have the same resources allocated. If there is a mix of dedicated hardware (non-virtualized IP Office) and virtualized IP Office operating as primary and secondary, then the assignment of resources to the virtual machine must match the hardware resources available in the dedicated hardware.
