4), that had not been mapped to any ports prior to the upgrade, will be mapped to FC HBA
ports on the auxiliary blade in the upgraded server.
The Ethernet connection entries in a profile are handled differently from SAN entries in order to
balance the use of Flex-10 ports (even if no Flex-10 ports are used, the same balanced approach
is used). Virtual Connect manager distributes the Ethernet connection entries across all of the blades
in a server, and on each blade it distributes connection entries across all of the Ethernet physical
ports. This is done so that as few Flex-10 sub-ports are used as needed, which results in maximum
band-width available to each Flex-10 sub-port. This distribution of Ethernet connection entries across
all Ethernet ports is done for single-blade servers, too. The net result is that the mapping of Ethernet
connection entries in a profile assigned to a server will change when that server is upgraded.
Consider a the following examples.
•
If the upgrade is from a BL860c i2 to a BL870c i2 then every other Ethernet connection entry
starting with the first entry (i.e., the first, third, fifth, etc. entries) will be mapped to ports on
the Monarch blade, and every other entry starting with the second entry (i.e., the second,
fourth, sixth, etc. entries) will be mapped to ports on the auxiliary blade.
•
If the upgrade is from a BL860c i2 to a BL890c i2 then every fourth Ethernet connection entry
starting with the first entry (i.e., the first, fifth, ninth, etc. entries) will be mapped to ports on
the Monarch blade; every fourth entry starting with the second entry (i.e., the second, sixth,
tenth, etc. entries) will be mapped to the first auxiliary blade; every fourth entry starting with
the third entry (i.e., the third, seventh, eleventh, etc. entries) will be mapped to the second
auxiliary blade; and finally every fourth entry starting with the fourth entry will be mapped to
ports on the 3rd auxiliary blade.
For example, a profile with 8 Ethernet connection entries where each entry defines a connection
to a different network (this makes it easy to see what happens when an upgrade is done). Assume
that the profile is assigned to a BL860c i2 that is upgraded to a BL870c i2. Assume that VC Flex-10
Interconnection modules exist in bays 1 and 2, thus the Flex-10 LOMs on the blades are utilized.
The following table shows how these entries are mapped to ports on the original server and to the
blades in the upgraded server.

If it is important that each of the networks be mapped to the same ports on the Monarch blade
after the upgrade, then the profile will need to be edited to add 7 Ethernet connection entries, and
then the entries must be edited to obtain the desired network connections aligned with the ports
