Note: Specific requirements on RealPresence Collaboration Server Virtual Edition installation
The RealPresence Collaboration Server Virtual Edition installation has the following specific
requirements on installation:
▪
Network Interface Card - Depending on the environment, the virtual machine may require a
Network Interface Card (NIC) from the host dedicated for the virtual machine.
▪
Dedicated VM Server - To maximize audio and video quality Polycom strongly recommends
a dedicated VM server per RealPresence Collaboration Server.
CPU Allocation
▪
Leave 2 cores unallocated, regardless of the number of cores present, how many licenses are
purchased, and what other virtual machines will be present.
▪
For VMware, do not allocate CPU core 0. Host operating system performance may be affected if
this core is assigned to the virtual machine.
▪
When possible, allocate cores on one CPU. This will enhance performance by reducing CPU-to-
CPU communication times.
▪
Do not use processor oversubscription; maintain a 2:1 ratio of virtual CPU to physical CPU. For
example, a system with 8 physical cores can support up to 16 virtual processors divided up into any
combination among the virtual machines running on that host.
▪
When you are using Hyper-V, Polycom recommends disabling the Virtual Machine Queue of the
Network Interface Card (NIC). For more information, see https://support.microsoft.com/en-us/kb/

Note: CPU reservations can only be done after shutting down the virtual machine.
Memory Allocation
In a Microsoft Hyper-V environment, you must not overprovision memory at the hypervisor layer. Dynamic
memory for virtual machines is not supported.
Disk
Hypervisors add overhead to disk operations. For best performance, ensure that the virtual machine is
able to achieve the recommended IOPS listed in the following table.
Disk Performance
Network
Capacity information such as storage space and memory varies according to virtual edition. Please see
release notes for your RealPresence virtual edition software for the minimum capacity requirements for
your product.
