P12688-B21 is the Microchip SmartRAID SR416i-a x16 Lanes 4GB Cache NVMe/SAS 24G Controller for HPE Gen10 Plus servers. It is a tri-mode controller, so one controller handles NVMe, SAS and SATA drives behind the right backplane or cage.
In the ProLiant DL380 Gen10 Plus it is one of the tri-mode controller choices, together with the MR416i-p, MR416i-a, MR216i-p, MR216i-a and SR932i-p. PE80xx NVMe drives are not supported with it.
The cages and backplane kits it works with include the DL38X Gen10+ 2SFF x4 Tri-Mode U.3 Kit (P26922-B21), the DL38X Gen10+ 8SFF x1 Tri-Mode U.3 Kit (P27193-B21), the DL300 Gen10+ 2U 8SFF x4 Tmode U.3 Kit (P26931-B21), the DL300 Gen10+ 2U 2SFF x4 Tmode U.3 Kit (P26924-B21) and the DL300 Gen10+ 2U 8SFF x1 Tmode U.3 Kit (P27194-B21). SAS/SATA kits also work, among them the DL38X Gen10+ 4LFF SAS/SATA LP Kit (P55700-B21), the DL380 G10+ 2SFF SAS/SATA Pri/Sec Kit (P55696-B21) and the DL300 Gen10+ 2U 8SFF SAS/SATA BC Kit (P55516-B21), as do the default 8SFF SAS/SATA drive cages that come standard on the configure-to-order server.
For 24G SAS speed with non-SED SAS4 drives, a U.3 backplane or cage is needed together with either this SR416i-a or the SR932i-p tri-mode controller. Without that combination the drive downclocks to 12G SAS.
The spare number is P13928-001, the tri-mode controller assembly for this model.
More RAID controllers and adapters are in HPE controllers and adapters.
