Storage
With a variety of storage controllers and drive types, the PowerEdge MX740c provides expandability that allows you to tailor your
storage to match your workload and operational demands. Options include boot devices, a portfolio of PERC controllers and HBAs,
SAS and SATA hard drives and SSDs, and NVMe SSDs.
Supported hard drives
The MX740c supports up to six 2.5-inch, hot-swappable SAS, SATA hard drives, SSDs, or PCIe NVMe drives. The drives are supplied
in a hot-swappable drive carrier and connect to the system board or RAID controller through the backplane.
NOTE: When NVDIMMs are installed in the MX740c, the available 2.5-inch drive bays are reduced to 4 to accommodate
the battery needed to protect the DIMMs during a power loss.
RAID controllers
PERC provides a base RAID HW controller without consuming a PCIe slot by using a small form factor and high density connector to
the system board.
The following table shows the PERC series offerings.
