Dell EMC PowerEdge MX5016s and MX5000s Installation and Service Manual

In the PowerEdge MX7000 enclosure, drives inside a Storage Sled map to Compute Sleds. The PowerEdge MX7000 enclosure supports multiple Storage Sled to compute sled-mapping configurations.

Each slot in the MX7000 chassis supports a compute sled or a storage sled, and there are no fixed mappings for the sleds. Using the OpenManage Enterprise-Modular web interface the disks in a storage sled can be mapped to a compute sled with the following options:

• Map an entire storage sled (Enclosure- Assigned Mode) to a compute sled.
• Map a specified group of disks (Drive- Assigned mode).

Mapping requirements and restrictions:

• Each compute or storage sled has two x4 SAS paths, with one path connecting to each of the two Fabric-C IOMs.
• The SAS storage solution requires two MX5000s IOMs installed in Fabric-C to provide redundant path.
• IOM C1 connects to Expander 1 in each of the installed Storage Sleds.
• IOM C2 connects to Expander 2 in each of the installed Storage Sleds.
• Each Expander within a storage sled connects to all 16 SAS drives, providing redundant paths.
• Any compute sled intended to connect to the SAS storage must have a Fab-C mezzanine card installed (either the HBA330 MMZ or the PERC MX745P).
• Compute sleds with the MX745P controller option may also choose to use the internal drives on the compute sled, within the same virtual drive as drives within a mapped storage sled.
• In Drive-Assigned mode, disks are visible to only a single compute sled, and can be assigned in any order or quantity.
• In Enclosure-Assigned mode, all 16 drive slots are mapped to the selected compute sled. In this mode, more than one compute sled can be mapped to the storage sled, which means the disks are visible to more than one compute node simultaneously.
