How many network ports are available on this HPE 842QSFP28 adapter?

This adapter is described as a 1-port 842QSFP28 unit, meaning it offers a single network port. That single port delivers 100Gb Ethernet connectivity, which is useful when you need one high-bandwidth link per server or device rather than multiple lower-speed connections.

What connector type does the HPE 877697-001 adapter use?

: "The adapter is categorized as a 1-port QSFP28 100Gb adapter. This means its single 100Gb Ethernet port uses a QSFP28 interface, which is commonly deployed with 100Gb optics or direct-attach cables in data center environments standardizing on QSFP28 for high-speed networking.

What kind of slot does this 100Gb adapter require in a server?

The adapter is listed under the category Network Adapter, PCIe 3.0 x16 100Gb Ethernet, 1-port QSFP28 100Gb adapter. This indicates it is intended for installation in PCIe 3.0 x16 slots in compatible systems, aligning with standard server expansion capabilities for high-bandwidth network adapters.

How can I accurately reference this HPE 100Gb adapter for procurement?

You can reference this adapter using its SKU 877697-001 and its model description, HPE Ethernet 100Gb 1-port 842QSFP28 Adapter. Including both the SKU and the full product name in purchase and configuration documents helps avoid ordering errors and ensures consistent deployments.
