VIPRION System Overview
What is a VIPRION system?
The VIPRION® system is a complete traffic management solution that
offers high performance, reliability, scalability, and ease of management. Based on
chassis and blade technology, this system is designed to meet the needs of large,
enterprise networking environments that normally require multiple BIG-IP® systems to process large volumes of application traffic.
The VIPRION system includes multiple blades that work together as a powerful
cluster
to process
application traffic. When traffic comes into a single virtual server, the system
distributes that traffic over multiple blades using the full multi-processing capacity
of each blade. This ensures that other blades can complete the processing of the request
if one unexpectedly becomes unavailable.This illustration shows a typical VIPRION system with a four-slot cluster processing traffic
destined for virtual server
vs_http
. In this example, the virtual
server resides on all blades in the cluster, due to a process known as cluster
synchronization
. The primary blade receives the client traffic and then uses
the power of all blades in the cluster to process the traffic before sending the traffic
to the appropriate server.Example of a basic VIPRION system
About the VIPRION cluster
The VIPRION® system includes SuperVIP® cluster
technology, the core feature that coordinates all of the blades into a single
high-performance system. A
cluster
is a group of active slots in the
VIPRION system chassis. The size of the cluster depends on the number of running blades
installed in the chassis. Cluster technology provides the processing power of multiple
blades, but you manage the entire cluster as a single system. When you install a blade
in a slot and power on the blade, the slot automatically becomes a member of the
cluster.Each slot in the cluster represents a cluster member, and the blades in the
slots of a cluster work together to process application traffic. Moreover, the blades can be configured to mirror each other's connections so that if a blade is taken out of service or becomes unavailable for some reason, any in-process connections remain intact.
When two chassis are in a redundant system configuration, the VIPRION system mirrors the connections and session persistence records that the blades in a cluster are processing to the cluster in the other chassis. You can configure inter-cluster mirroring, for a redundant system configuration only, and only when the identical number of blades are present in the identical slot numbers in each of the two clusters of the redundant system configuration.
About the cluster IP address
One of the tasks you performed as part of the hardware installation was to assign a unique
cluster IP address to the primary slot in the cluster. This
cluster IP
address
is a floating management IP address used to access the blade in the
primary slot to manage the system. If the blade in the primary slot becomes unavailable
for any reason, the primary designation moves to a different slot, and the cluster IP
address floats to that slot.About cluster synchronization
The VIPRION® system automatically performs
cluster
synchronization
, an internal process that causes the primary blade to automatically
propagate the BIG-IP ®software configuration to all secondary blades, even
when a new blade is introduced into the cluster. Cluster synchronization allows all blades in the
cluster to work together to process incoming traffic, and ensures that you can always access the
cluster using the cluster IP address, even when the blade in the primary slot changes.About chassis and blade models
The number of slots in a chassis varies depending on the chassis model. For example, while some
chassis models contain two or four slots, the VIPRION® C4800
Series contains eight slots.
Each chassis model requires a specific blade type. For example, the VIPRION C4800 chassis
uses VIPRION B4300 Series blades. For specific information on blade types compatible
with your chassis, consult the platform guide for your chassis series.
About Virtualized Clustered Multi-Processing
If you need multi-tenancy, you can optionally provision the VIPRION®
system for virtual Clustered Multiprocessing (vCMP®). Provisioning vCMP
creates a hypervisor and allows you to create guests on the system for multi-tenant
processing.
This illustration shows a basic vCMP system with a host and four guests. Note that each guest has a
different set of modules provisioned, depending on the guest's particular traffic
requirements.

.Summary of cluster-related terms
There are several cluster-related terms that are helpful to understand.
Term |
Definition |
|---|---|
cluster |
The group of active slots in the chassis. The blades in the cluster work together
as one powerful system to process application traffic. Also known as a SuperVIP® cluster . |
cluster member |
An enabled physical slot (or a virtual slot) that contains an active
blade. |
cluster IP address |
The floating management IP address of the slot designated as the primary slot.
You normally assign the cluster IP address during VIPRION chassis
installation. |
primary slot |
The slot containing the blade that initially accepts application traffic. The
floating cluster IP address is assigned to the primary slot. If the blade in the
primary slot becomes unavailable, the cluster IP address automatically floats to
another cluster member and the slot of the new cluster member becomes the primary
slot. |
primary blade |
The blade residing in the primary slot. |
secondary slot |
Any slot that is not the primary slot and therefore does not have the floating cluster IP address assigned to it. |
secondary blade |
Any blade residing in a secondary slot. |
cluster member IP address |
The static management IP address assigned to a cluster member. |
cluster synchronization |
An ongoing, internal process by which the primary blade automatically propagates
the BIG-IP® system configuration to all secondary
blades when powered-on. Cluster synchronization allows all blades in the cluster to
work together to process network traffic. |
