6.1 Dell Blade Network Architecture

The Dell blade chassis has three separate fabrics referred to as A, B, and C. Each fabric has two I/O

modules, for a total of six I/O modules slots in the chassis. The I/O modules are A1, A2, B1, B2, C1, and

C2. Each I/O module can be an Ethernet physical switch, an Ethernet pass-through module, FC switch,

or FC pass-through module. Each half-height blade server has a dual-port network daughter card (NDC)

and two optional dual-port mezzanine I/O cards. The NDC connects to Fabric A. One mezzanine I/O

card attaches to Fabric B, with the remaining mezzanine I/O card attached to Fabric C.

In this solution, the Chassis Fabric A contains Dell I/O modules and is used for LAN. Fabric B contains

Dell 8|4 Gbps SAN modules and is used for SAN. The Fabric C is unused.

PowerEdge M620 blade servers use a Broadcom 57810-k Dual port 10GbE KR bNDC (blade Network

Daughter Card) to connect to the fabric A. Dell I/O modules uplink to Dell Networking S4810 network

switches providing LAN connectivity. QLogic QME2572 8 Gbps Fibre Channel I/O mezzanine cards are

used to connect to Dell 8|4 Gbps SAN modules. The uplinks of Dell 8|4 Gbps SAN modules connect to

Brocade 6510 switches providing SAN connectivity.

Figure 4 below illustrates how the fabrics are populated in a Dell blade server chassis and how the I/O

modules are utilized.
