Figure 15. Out-of-band management switch uplink connections
Top-of-Rack (ToR) switch connectivity options and
requirements
In addition to an out-of-band management switch you must deploy PowerStore T model with two ToR switches to support iSCSI
connectivity, replication, import, cluster, and Network Attached Storage (NAS).
Top-of-Rack (ToR) switch to ToR switch (L2) connectivity options
Use one of the following options to connect the two ToR switches together.

Recommendation
1. Multi-chassis Link
Aggregation Group (MC-LAG)
Dell highly recommends using MC-LAG for connectivity between the switches.
2. L2 Uplinks without MC-LAG If MC-LAG is not an option, then the next best recommended connectivity between the
switches is to use reliable L2 uplinks.
NOTE: If neither of the switch interconnect options are available then you can use a Direct Trunk Link, but this is not
recommended.
Multi-chassis Link Aggregation Group (MC-LAG) interconnect
It is highly recommended that you deploy PowerStore with an MC-LAG interconnect between the two ToR switches.
In an MC-LAG environment, the two switches are treated as one logical switch. This allows you to add all the uplinks from both
switches into a single port channel that will span the MC-LAG.
