Hardware Delivery - 6RU and 10RU devices
Blades
Internal Switches (Flex10)
Each blade has two physical 10 Gbps interfaces, also called pNIC. The use
of Flex10 modules, i.e. the internal switches of the blade center, allows to
demultiply these interfaces to reach a number of 8 interfaces, or FlexNIC:
4 by physical interface.
The allocation of the 10 Gbps of a physical interface between the
4 FlexNIC is customizable. To make this bitrate allocation, you must use
the HP interface to configure the Flex10:
 10RU device: one physical interface is on the first Flex10, the other is
on the second Flex10.

6RU device: both physical interfaces are on the first Flex10. We add a
mezzanine to the blade so as to have also two physical interfaces on
the second Flex10. In total, there are consequently 16 FlexNIC.
To know how to use the HP interface, refer to the HP Virtual Connect for
c-Class BladeSystem - User Guide provided on the DVD-ROM.
Interface Bonding
Interfaces are grouped in bonds, in fail-over mode, with the main
interface always being on the first Flex10.
10RU Device
Each blade has 8 network interfaces. On the Flex10, they are named
LOM:1-a to LOM:4-a and LOM:1-b to LOM:4-b;
a blades being on the first
Flex10 and b blades on the second one.
On the 10RU device, interfaces are defined as follows:
 Interface 1: LOM:1-a & LOM:2-a

Interface 2: LOM:1-b & LOM:2-b
 Interface 3: LOM:1-c & LOM:2-c
 Interface 4: LOM:1-d & LOM:2-d
The currently active NIC remains active while it is up, there is no
automatic restore when the other NIC becomes up again.
