OMPONENTS
The TD140’s architecture consists of the components listed in
:
Iris Server
Correlates session records and forwards to ISA.
Stores TD140 configuration settings (configured in Irisview Admin on Iris client)
DataCast
Correlates XDRs and processes them into Output Hybrid Data Records (OHDRs)
and forwards them to the IPI preprocessor.
IPI Preprocessor
Processes OHDRs and calculates and aggregates KPIs for use in IPI applications.
Iris Client
Admins configure TD140 settings.
Users view correlated session record results matching their filter criteria in ISA.
Users view KPIs/KQIs in IPI applications and reports.

Chassis
The TD140 chassis has:
A Shelf Management Controller (ShMC)
Two redundant and hot-swappable PEMs
Two pluggable, hot-swappable fan trays
A Removable fan filter
Shelf Management
Controller (ShMC)
The ShMC has two Gigabit Ethernet ports with RJ-45 connectors:
Port A - Used during initial TD140 configuration; not used during normal probe operation
Port B - OAM interface for communicating with Iris server
Packet Processing
Module (PPM40)
The PPM40 packet processing module provides high-performance packet processing for the
TD140. The PPM delivers I/O processing for 10 gigabit and 1 gigabit (Gb) Ethernet interfaces.
Each PPM40 blade provides four egress port connections to the G10 probes.
PPM40 ETH port (Slot 1) - Used as OAM interface for receiving session data from the
probes
PPM40 Rear
Transition Module
(RTM)
The PPM40 supports the PPM40 RTM, which connects to the back of the TD140 chassis.
Each RTM provides the PPM40 with twelve ports:
Eight ingress ports for connection to monitored network
Four egress ports for connection to G10 probes
