PB100 and PB200 blade compatibility
You can use both PB100 and the newer PB200 blades in a VIPRION system
that is running BIG-IP version 10.1 or later.
Blade performance in mixed clusters
If you choose to create a
mixed cluster
, a system that includes both blade
types, any PB200 blades will perform at the same level as the PB100 blades.
Removing all PB100 blades from a mixed cluster, leaving only PB200
blades, enables the PB200 blades to perform at their maximum capacity.
Blade software versions in mixed clusters
The behavior of a mixed cluster differs depending on the software versions
installed on the blades.
PB200 blades in a cluster running BIG-IP version 10.0.x and earlier
If you install a PB200 blade in a PB100 cluster running a version of the
BIG-IP software that is earlier than version 10.1, you could experience the
following scenarios:
◆
You receive an error message in the cluster status for the slot in which
the PB200 blade is installed, indicating that the blade is running the
wrong software version. The software installation status also displays an
error for the PB200 blade slot.
◆
Earlier BIG-IP software versions may display in the Configuration
utility, but you will not be able to install them to the PB200 blade. You
receive an installation error message if you attempt to install an earlier
version of the BIG-IP software.
◆
If you upgrade the cluster to version 10.1 or later, the PB200 blade joins
the cluster as an active member.
◆
If the PB100 blades are subsequently removed from the cluster, the
situation does not correct itself automatically, as the system will
remember that the version of software for that cluster is a version prior to
version 10.1. You can correct this issue by specifying that version 10.1 or
later run on the cluster.
◆
If you move a PB200 blade to a second chassis, this does not cause the
other chassis to downgrade to a version earlier than version 10.1. Cluster
configuration information, which includes the software version
information, is tied to the chassis identifier on the chassis hardware and
is removed from the blade when it is moved to another chassis.
