Dedicated deployment
In a dedicated deployment scenario, each application is deployed on its own
MAS pair to the maximum capacity of that single application. However, for the
most efficient use of resources, a combination of dedicated deployment and
multi application deployment is required.
Co-resident deployment
In a co-resident deployment, up to five MAS applications (Meet-Me, Ad Hoc,
Music on Hold, Announcements, and Unified Communications) can be
deployed on the same MAS duplex.
If you choose a co-resident deployment, you must stay within the engineered
capacity limits for that co-resident deployment. You cannot, for example,
expand the capacity for Meet Me and balance that by reducing Unified
Communications capacity. If you require additional application capacity, you
can add an additional MAS pair and deploy a dedicated service to
accommodate the additional capacity requirements for that service. For
example, if you currently have a combination five deployment, and you require
additional Meet Me capacity, you can purchase additional Meet Me licenses
and servers and deploy a dedicated Meet Me server cluster to handle the
increased capacity.
The available co-resident deployment options are defined in the following
sections.
Co-resident Application Deployment (including Meet Me)
In a Co-resident Application Deployment (excluding Meet Me), all five MAS
applications are deployed on the same MAS pair.
Co-resident Application Deployment (excluding Meet Me)
In a Co-resident Application Deployment (including Meet Me), Ad Hoc, Music
on Hold, Announcements, and Unified Communications are deployed on one
MAS pair and a separate MAS pair is dedicated to Meet Me Conferencing.
Maintenance Releases
The MAS is updated or downgraded using executable installers (DVDs). To
update the MAS to the latest maintenance release, you must obtain the latest
maintenance release DVD and install the software. To downgrade to an earlier
maintenance release, you must run the installer on desired maintenance
release DVD. For the procedures to update and downgrade maintenance
releases, see Nortel Media Application Server 6.0 for AS 5300 Installation
(NN44470-300).
