Figure 5. Multipath topology for the MX7000 modular system
In this illustration, the H745P MX resides in the compute sled and functions as an interface to the SAS topology of the MX7000. The
H745P MX is used to congure drives that are located in the MX5016s storage sled into RAID volumes. The H745P MX connects to a pair
of MX5000s SAS I/O modules (IOMs) that manage connections between the compute and storage sleds in the MX7000. For more
information about conguring drive assignments, see the Dell.com/openmanagemanuals > OpenManage Enterprise Modular.
NOTE
: The I/O modules cannot be congured independently.
The H745P MX 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 physical drives in the storage sled, providing one path between the H745P MX and a physical drive
in the storage sled. With connections to both SAS IOMs, the H745P MX has two paths to each drive in a storage sled allowing for a multi-
path conguration. If either a SAS IOM or a SAS expander in the storage sled is removed, then a path to the physical drive is removed from
the SAS topology.
