• Depending on your server models, your server supports the following drive types:
– NVMe SSD
– SAS/SATA SSD
– SAS/SATA HDD
For a list of supported drives, see:
https://static.lenovo.com/us/en/serverproven/index.shtml
• The drive bays are numbered to indicate the installation order (starting from number "0"). Follow the
installation order when you install a drive. See "Front view" on page 21.
• You can mix drives of different types, different sizes, and different capacities in one system, but not in one
RAID array. The following order is recommended when installing the drives:
– Drive type priority: NVMe SSD, SAS SSD, SATA SSD, SAS HDD, SATA HDD
– Drive size priority: 2.5 inch, 3.5 inch
– Drive capacity priority: the lowest capacity first
• The drives in a single RAID array must be the same type, same size, and with the same capacity.
• Some server models support NVMe drives and the bays for installing NVMe drives vary by model:
