Drive bays
Drives are all located at the front of the server, 12 drives at the front of the upper tray and 12 at the front of
the lower tray. Drives are connected to 4-drive backplanes in a 2-by-2 configuration, as shown in the
following figure. All drive bays are 2.5-inch form factor.
Two different drive backplanes are available for the server:
• SAS/SATA backplane: Supports 4 SAS or SATA drives
• AnyBay backplane:
– Top two drives support SAS, SATA, or NVMe interface drives (Lenovo AnyBay). The server can support
up to 12 NVMe drives, depending on the server configuration. The NVMe-capable drive bays are the
even-numbered bays as shown in Figure 8 "Drive bay locations" on page 17.
– Bottom two drive bays support SAS or SATA drives only
Regular 2.5-inch SAS/SATA drive bays support only SAS or SATA drives; however, the Lenovo AnyBay drive
bay design allows a choice of SATA, SAS, or U.2 (NVMe) PCIe drives. This design enables the flexibility to
configure some of the bays with high-performance PCIe SSDs while still using the other bays for high-
capacity HDDs, which is an ideal solution for storage-tiering.
