HPE 700751-B21 FlexFabric 10Gb 2-Port 534FLR-SFP+ FlexibleLOM Adapter

700751-B21 is the HPE FlexFabric 10Gb 2-port 534FLR-SFP+ adapter, a FlexibleLOM card, and HPE PartSurfer gives its spare part number as 701531-001. PartSurfer's product description names the controller as the 57810S, and HP's ProLiant DL380p Gen8 QuickSpecs list the 534FLR-SFP+ with a BCM57810S chipset, a PCI Express x8 connection and two SFP+ connectors.

The QuickSpecs for both the DL380p Gen8 and DL360p Gen8 include 700751-B21 among their FlexibleLOM choices, next to the 533FLR-T (700759-B21) for 10GBASE-T copper and the 554FLR-SFP+ (629142-B21). Those same documents also list a factory-integrated version, 700752-B21, for servers built to order.

Because the ports are SFP+ cages, the card needs transceivers or direct attach cables; PartSurfer pairs the 700751-B21 with the c-Class 10G SFP+ LC SR (456096-001) and LC LR (456097-001) transceivers. HP's DL360p Gen8 QuickSpecs describe the server as having one FlexibleLOM connection point, which is where this card installs. To confirm fit, check that the server's QuickSpecs list FlexibleLOM support and read 701531-001 on the installed card's spare label. For 10GBASE-T copper cabling choose 700759-B21, or for the 554FLR-SFP+ adapter choose 629142-B21; other Gen8 FlexibleLOM and riser options are on the HPE ProLiant DL380p Gen8 parts hub.
