Blade server chassis integration
57 Dell PS Series Configuration Guide
11 Blade server chassis integration
Integrating the PowerEdge M1000e Blade Server Solution (or any third-party blade chassis implementation)
requires additional SAN design considerations. Each M1000e can support up to three separate networking
“fabrics” that interconnect ports on each blade server to a pair of blade I/O modules within each chassis fabric
through an intervening chassis midplane interface. Each fabric is associated with different interfaces on a
given blade server as described in Table 37. Each blade server has a “LAN on Motherboard” capability that is
mapped to the I/O modules located in the Fabric A I/O modules slots on the M1000e chassis and only
supports 1Gb or 10Gb Ethernet networking depending on the blade server model. In addition, each blade
server has two “mezzanine” sockets for adding networking options such as 1Gb or 10Gb Ethernet, Infiniband,
or Fibre Channel cards. These mezzanine cards are mapped to either the Fabric B or the Fabric C I/O
modules.
Figure 20 illustrates the layout of the three fabric I/O modules located on the back of the M1000e chassis.
