Figure 6. Multipath topology for the MX7000 modular system
In this diagram, the HBA330 MMZ resides in the compute sled, and functions as an interface to the SAS topology of the MX7000. The
HBA330 MMZ connects to a pair of MX5000 SAS I/O modules (IOMs) that manage connections between the compute and storage sleds
in the MX7000. For more information on conguring drive assignments, see the Dell EMC OpenManage Enterprise Modular User's Guide.
NOTE
: The I/O modules cannot be congured independently.
The HBA330 MMZ is connected to the SAS IOM, which in turn connects to one of the SAS expanders in the storage sled. The expander in
the storage sled is then connected to all the drives in the storage sled, providing one path between the HBA330 MMZ, therefore, and a
drive in the storage sled. With connections to both SAS IOMs, the HBA330 MMZ has two paths to each drive in a storage sled, allowing for
a multipath conguration. If either a SAS IOM or a SAS expander in the storage sled is removed, then a path to the drive is removed from
the SAS topology.
