Host Media Processing Software Release 4.1LIN Release Guide 19
Features
For additional information about operating system requirements, see Section 2.2, “Basic
Software Requirements”, on page 13.
This feature specifically focuses on the VMware
®
ESXi 4.0 installable product which
provides a native (or full) virtualization layer running on physical servers for abstracting
processor, memory, storage, and resources into multiple virtual machines. For more
information about virtualization, refer to the VMware web site at www.vmware.com.
Notes:1. It is assumed that the reader is familiar with common terms used to describe basic
virtualization concepts, such as guest operating system, host, hypervisor, etc.
2. Virtualization is not supported on thin-blade configurations.
3.6.1 VMware
®
ESXi 4.0 Virtualization Support
Dialogic
®
HMP virtualization refers to the capability of running a separate instance of the
Dialogic
®
HMP software release on the “guest” operating system of one or more virtual
machines being hosted on the same physical platform (i.e., server). Each Dialogic
®
HMP
software release has a separate runtime license, a number of dedicated resources, and
requires a dedicated application (written to standard Dialogic
®
HMP Global Call and R4
Media API) to manage the resources.
HMP virtualization is implemented using VMware
®
ESXi 4.0 Update 1 Installable.
VMware
®
ESXi partitions a physical server into multiple secure and portable virtual
machines that can run side by side. Each virtual machine represents a complete system—
with processors, memory, networking, storage and BIOS—so that an operating system
and software applications can be installed and run in the virtual machine without any
modification.
Refer to the VMware
®
ESXi 4.0 documentation at http://www.vmware.com/support/pubs/
for more information.
The density achieved when operating in an virtual environment is directly dependent on
the configuration settings of the virtual machine (i.e., CPU, memory, etc.) and the host
platform hardware. Users should view the configuration settings provided as guidelines
and not absolute, based on the target platform hardware characteristics in which feature
validation was performed. Customizing the settings for optimal performance based on
needs of the controlling application and host platform should be done by knowledgeable
and experience personnel familiar with VMware
®
ESXi products.
3.6.2 Configuring HMP Virtualization
To configure Dialogic
®
HMP software to run as close as it would in a physical server
configuration, the hypervisor should be configured to distribute the host hardware CPU
processor, memory, storage, and networking resources to enable the real-time processing
of RTP, media, and call control on all instances of the Dialogic
®
HMP software. The
following subsections examine the critical parameters to achieve this goal. Please refer to
the vSphere Resource Management Guide found at
http://www.vmware.com/pdf/vsphere4/r40_u1/vsp_40_u1_resource_mgmt.pdf for a
thorough explanation of the terms and concepts utilized herein.
