HPE FlexFabric 10Gb Adapter for Gen9 Blades

This refurbished HPE FlexFabric 10Gb 2-port 536FLB Adapter fits HP ProLiant Gen9 Blade servers as a FlexibleLOM module. It provides converged 10 Gb connectivity for Ethernet, FCoE and iSCSI traffic. The dual-port design supports SR-IOV virtualisation features for dense server environments.

Dual 10 Gb ports via FlexibleLOM slot

The module delivers two 10 Gigabit Ethernet ports through the blade FlexibleLOM interface. This form factor is the deciding specification; it only installs in compatible Gen9 blade servers with an available FlexibleLOM bay. Systems without that slot cannot use this adapter.

Low-profile blade thermals

As an internal blade module, cooling depends on the enclosure fans and shared airflow. Power draw is supplied through the blade backplane, so no separate power connector is required. Acoustic output follows the overall chassis fan profile rather than adding distinct noise. Not for rackmount servers or non-HPE blade platforms.

Questions about this item

How much throughput does each 10 Gb port deliver inside a ProLiant Gen9 blade?

Each port runs at 10 Gb/s, giving two independent 10 Gb lanes for Ethernet, FCoE or iSCSI traffic within the blade chassis.

What slot standard does the 536FLB use and what bandwidth ceiling does it impose?

The adapter plugs into a FlexibleLOM slot, so the 20 Gb total I/O is limited by that blade interconnect rather than a PCIe lane count.

Which blade form factor and generation does the 766490-B21 physically fit?

It is a FlexibleLOM module designed for HPE ProLiant Gen9 BladeSystem servers, mounting directly in the blade mezzanine bay.
