Media Application Server platform
For the NTVW01CH and NTVW01CV Blades, each blade occupies a single
slot.

IM Chat service
Only one Media Application Server running the IM Chat service is allowed
in each root domain; therefore the IM Chat service is only available in the
simplex architecture. The IM Chat service does not require content storage;
for the simplex architecture, you require a single-slot Media Application
Server, consisting of an IBM HS20 blade server. You can place this
single-slot blade server in any of the slots of the IBM eServer BladeCenter
or BladeCenter T chassis.
BCP/MAS Co-residency
The BladeCenter supports both the Border Control Point (BCP) and
Media Application Server (MAS) applications. The resulting co-residency
provides an appealing solution for initial deployments (including internal lab
environments), and a more flexible growth strategy for existing deployments.
The effective treatment of BCT chassis real estate as a pooled resource
that can be utilized by either BCP or MAS components also results in the
optimized usage of chassis capacity (that may reduce the number of chassis
required in certain deployments).
Co-residency of BCP and MAS applications is governed by the following
rules:
•
BCP applications are populated starting at blade 1 of the chassis, and
working down the chassis.
•
MAS applications are populated starting at blade 8 of the chassis, and
working up the chassis.
•
When more than eight applications are required, additional BCTs can be
added to the system.
