Reference Architecture for Active System 800m with Hyper-V:
Dell Inc. 10
6.1 Dell Blade Network Architecture
In this solution, the Chassis Fabric A contains Dell Force10 IO Aggregator modules and is used for
converged LAN and SAN traffic. Fabric B and Fabric C are not used.
M620 blade servers use the Broadcom 57810-k Dual port 10GbE KR Blade NDC to connect to the
Fabric A. Dell Force10 IO Aggregator modules uplink to Dell Force10 S4810 network switches providing
LAN AND SAN connectivity.
Figure 3 below illustrates how the fabrics are populated in a Dell blade server chassis and how the I/O
modules are utilized.

6.2 Server / Blade Network Connectivity
The network traffic on each blade includes iSCSI as well as traffic for the parent partition (hypervisor),
Live Migration, cluster heartbeat, cluster shared volume, and child partitions (virtual machines).
A fault-tolerant network team is created by using:
· Two 10 GbE NDC ports for each blade
· A virtual switch is provisioned in Hyper-V
· A virtual network adapter that is:
o Created
o Shared with the parent partition
o Segmented with VLANs
o Applied with bandwidth weighting
