join the VC Domain Group if it has any features enabled beyond the features supported by the
group firmware mode.
Table 4 illustrates how the group firmware mode is determined based on the versions of VC firmware
installed on the VC Domains in the VC Domain Group.

3.3x 3.7x 3.60 3.5x 3.30 GroupTwo
3.5x 4.1x 4.0x 3.7x 3.60 GroupThree
GroupOne contains four domains running 3.18, 3.30, and 3.60 VC firmware. The group firmware
mode is 3.15 because of the 3.18 VC Domain in the VC Domain Group.
GroupTwo contains four VC Domains running 3.30, 3.5x, 3.60, and 3.7x. The group firmware
mode is 3.3x because 3.30 is the lowest version in the group.
GroupThree contains four VC Domains running 3.60, 3.7x, 4.0x, and 4.1x. The group firmware
mode is 3.50 because 3.60 is the lowest version in the group and 3.60 shares group firmware
mode with VC 3.5x.
The group firmware mode also is a factor when creating a VC Domain Group based on a VC
Domain running a newer version of VC firmware than what is fully supported by the version of
VCEM managing the VC Domain Group. In this case, VCEM automatically sets the group firmware
mode when creating the VC Domain Group. VCEM sets the group firmware mode to the highest
firmware version that is fully supported by the version of VCEM being used to create the VC Domain
Group.
Table 5 shows the group firmware mode that will be set by recent versions of VCEM when the VC
Domain Group is created using a more recent version of VC firmware.

releases of VC firmware. 7.3
Creating a VC Domain Group based on a VC Domain running a newer version of VC firmware
requires that no features are enabled in the VC Domain that are beyond those supported by the
version of VCEM managing the VC Domain Group. For example, attempting to create a VC Domain
Group with VCEM 6.3 based on a domain with 3.30 installed and enhanced VLAN capacity
enabled will not succeed.
Preparing for a VCEM installation
IMPORTANT: Starting with Insight Management 7.0, you must run VCEM on a 64-bit operating
system.
