Frequently asked questions

What network speeds are supported by the HPE 817753-B21 adapter?

The HPE Ethernet 10/25Gb 2-port 640SFP28 Adapter 817753-B21 supports 10 Gigabit Ethernet and 25 Gigabit Ethernet data link protocols. Each of its two SFP28 ports operates as a 25Gb Ethernet interface while retaining compatibility with 10GbE environments. This allows the same adapter to be used during transitions from 10GbE to 25GbE networking.

How many ports does the HPE 640SFP28 adapter provide and what type are they?

The adapter provides two network interfaces. These are implemented as 2 x 25Gb Ethernet ports using SFP28 connectors. With a port quantity of two, the card enables configurations such as redundant uplinks, link aggregation, or separation of traffic types on a single PCIe expansion card.

What is the maximum throughput of the HPE 817753-B21 network adapter?

The adapter offers bandwidth per port of up to 50 Gbps and a total bidirectional throughput of 100 Gbps. This means that each of the two 25Gb Ethernet SFP28 ports can handle high traffic volumes, and together they provide substantial aggregate capacity for demanding server workloads.

Which bus interface does the HPE Ethernet 10/25Gb 2-port 640SFP28 Adapter use?

The HPE 817753-B21 adapter uses a PCI Express 3.0 host interface. It is compatible with PCI Express 3.0 x8 and PCI Express 3.0 x4 slot configurations. This allows deployment in a variety of server platforms that support PCIe 3.0, making integration straightforward for many rack or tower systems.

Does the HPE 817753-B21 support jumbo frames and if so, to what size?

Yes, the adapter supports jumbo frames. It allows jumbo frame sizes up to 9.6 KB. This capability helps reduce overhead for large data transfers and can improve efficiency in applications such as storage networking, backup operations, and other high throughput workloads that benefit from larger Ethernet frames.

Is the HPE 640SFP28 adapter a wired or wireless network solution?

The HPE Ethernet 10/25Gb 2-port 640SFP28 Adapter is a wired network adapter. It is implemented as a plug-in card form factor that installs into a PCI Express slot and uses cabled connections through its two 25Gb Ethernet SFP28 ports to link servers to switches or other network infrastructure.

What type of form factor does the HPE 817753-B21 network adapter have?

The adapter is described as a plug-in card network adapter form factor. It is designed for installation in server expansion slots that support PCI Express 3.0 x8 or x4 interfaces, integrating directly into the system motherboard for high speed, wired Ethernet connectivity.
