Enablement Kit for DL360 Gen11

The HPE P51911-B21 is an enablement kit designed for the ProLiant DL360 Gen11 server. It connects the first CPU socket to the OCP 2.0 slot with an x8 lane allocation. This new component weighs 0.06 kg and measures 30.5 x 21.5 x 1 cm.

Administrators expanding OCP connectivity

This kit suits administrators adding a first-CPU OCP 2.0 link to a DL360 Gen11 chassis. Builders using a different server model or a different generation cannot install this part. It also does not address configurations requiring a second CPU connection.

CPU1 to OCP2 x8 lane assignment

The single specification that decides fit is the CPU1 to OCP2 x8 lane assignment. The kit is keyed for the first processor socket and an x8 electrical interface on the OCP 2.0 mezzanine slot. Verify the server configuration matches this exact topology before purchase.
