What is the host interface of the adapter?

The adapter uses a PCIe v2.0 x8 interface. That bus type is specified in the source data and is important when matching the card to a compatible server slot.

What throughput figures are listed for this adapter?

The source data states two ports, each at 20 Gbps full duplex, with 40 Gbps aggregate full duplex theoretical bandwidth. It also says the adapter delivers full line-rate Ethernet NIC performance across all ports.

Which server families is this adapter designed for?

The adapter is designed for HPE ProLiant Gen8 and Gen9 rack servers. The product data presents that platform fit explicitly, which helps narrow deployment to supported HPE systems.

What controller or Ethernet solution does it use?

The adapter features the QLogic 57810S 10 Gb Ethernet solution. This chipset identification is part of the provided specifications and is useful for technical validation and platform review.

Product overview

The HPE FlexFabric 10Gb 2-port 533FLR-T Adapter, SKU 700760-B21, is an enterprise network adapter in the 10Gb Ethernet PCIe adapter category. It is a dual-port 10GBASE-T FlexibleLOM network adapter designed for HPE ProLiant Gen8 and Gen9 rack servers. The adapter uses the QLogic 57810S 10 Gb Ethernet solution and is built on a PCIe v2.0 x8 interface. According to the product data, it delivers full line-rate Ethernet NIC performance across all ports and supports low power consumption. The data also indicates two ports with 20 Gbps full duplex per port and 40 Gbps aggregate full duplex theoretical bandwidth. This makes it suitable for server environments that require a dual-port 10GbE design and a FlexibleLOM form factor for compatible HPE platforms.
