Dell chassis converged infrastructure: VMWare, M1000e, MXL, PS6210XS, S4810P

This is a highly redundant, high performance configuration that has 80GbE stacking interconnects for vMotion. Since we are stacking chassis 1, fabric A1 with chassis 2, fabric A1, east/west VMware traffic does not need to go to slower uplinks to TOR. Since chassis 1, fabric A2 and chassis 2, fabric A2 are a separate stack it provides resiliency and capability to update switch firmware without downtime.

Since stacking does take down the entire stack when upgrading firmware, this is not considered best practice for all enterprise environments. VLT between MXLs can provide full redundancy and performance but not same performance as stacking.
