9 Best Practices for Deploying a Mixed 1Gb/10Gb Ethernet SAN using Dell Storage PS Series Arrays | BP1008
connections can result in loss of access to storage in the event of a switch failure. Figure 5 shows an example
of split connect. Additionally, Rapid Spanning Tree (RSTP) would need to be configured appropriately to block
the loop path for traffic.
Note: Configuration documentation for specific supported switches can be found at the Rapid EqualLogic
Configuration Portal.
Stacked 1Gb fabric LAGd to a LAG-connected 10Gb fabric – use of RSTP is required
3.3 Method 3
Lastly, if neither the 1Gb or the 10Gb switches support stacking, both the 1Gb and 10Gb switches must be
connected together using LAGs to create each switching fabric. In this case, the two switching fabrics (1Gb
and 10Gb) can only be connected to each other using the straight connect LAG method as shown in Figure 6.
This configuration would also require the use of RSTP to block the loop path for traffic.
