1 Dell Technologies JumpStart network architecture
The JumpStart Solution is built on a simplified network architecture. In this design, the hosts are connected to
a pair of ToR (Top of Rack) switches. While the rack server configuration is obvious, the MX configuration,
using the pass-through Input Output Modules (IOMs) is the same but less obvious.
Using the pass-through IOM directly connects the A-fabric NIC port to the corresponding external port on the
pass-through IOM. This is the same as the connectivity for the rack-based ToR except that the modular
servers must pass through this additional layer of physical connection adapter.
The overall design is one where the connections from the servers to the ToR switches are trunked (not
aggregated) with all the VLANs required. Routing is accomplished at a layer above the ToR switches. This
connection diagram shows a simplified diagram of the network architecture.

Note that the ToR switches could be replaced with MX7000 modular switches and the R640 rack servers
could be replaced with either R740 rack servers or MX740c modular compute sleds, as appropriate. The
overall diagram is conceptionally appropriate for either rack or MX7000 modular deployments. The out-of-
band management network has been omitted from this diagram to make the data paths easier to visualize.
