Line Rate Processing—Iris Interface Card (IIC)
Consisting of a tiered pair of NPUs, the Iris Interface Card is able to process raw packets at
line rate speed with a distributed internal architecture and purpose-specific processing
functions.
Packet Processor NPU-packet classification with fast processing requirements and
lower memory requirements.
Flow Processor NPU-flow specific criteria processing across multiple packets with
higher memory requirements.
The Iris Interface Card’s dual NPU architecture allows
for independent upgrades of each or
either NPU as desired-allowing additional processing power to be added incrementally as
needed and available.
User Plane and Control Plane Processing—Iris Interface Card (IIC)
and Application Blade
As the GeoProbe G10 architecture can support both User plane and Control plane processing
with the same hardware, domain-specific sizing rules have been applied to maximize
processing performance for both traffic types.
While the Iris Interface Ca
rd h
andles the majority of the User Plane processing, the Control
Plane is forwarded directly to the x86 Application Blade for analysis, correlation and
processing functions.
Storage Subsystem—Store to Disk
In addition to I/O ports, interface processors and application boards, the GeoProbe G10
architecture relies upon a storage subsystem to further optimize processing functions.
Native Store to Disk (S2D) capabilities ensure line rate proces
sing performance integrity by
capturing and storing monitored packets for use with applications requiring more extensive
and expansive data collection.
The incorporation of a RAID dual controller disk ar
ra
y with every GeoProbe G10 installation
provides the additional capacity required.
Refer to Storage Subsystem for more details about the storage system hardware components.
