What is the full product identifier for this HP network adapter?

The adapter is identified as the HP 843QSFP28 100GbE Dual Port ConnectX-4 Adapter with SKU P05952-001. This naming combines the HP brand, the 843QSFP28 model designation, and the ConnectX-4 technology reference. Using the exact SKU P05952-001 helps ensure precise matching in procurement systems and avoids confusion with other similar HP network adapters.

Which interface slot does the HP 843QSFP28 100GbE adapter use?

This adapter belongs to the PCI Express 3.0 x16 Ethernet adapter category. That means it is intended for installation in a PCIe 3.0 x16 slot in a compatible server. When planning deployments, IT teams should verify that target systems provide available PCI Express 3.0 x16 slots to host this 100GbE adapter and deliver the required bandwidth.

What type of Ethernet connectivity does this adapter provide?

The HP 843QSFP28 100GbE Dual Port ConnectX-4 Adapter provides dual port 100 Gigabit Ethernet connectivity through QSFP28 interfaces. It is listed as a dual port 100 Gigabit QSFP28 product, aligning it with 100GbE network infrastructures. This makes it suitable for scenarios where servers need two 100GbE connections using QSFP28-based cabling and optics.

How many network ports are available on this HP adapter?

The adapter is defined as a dual port 100 Gigabit QSFP28 product, meaning it offers two 100GbE network ports. Each port uses the QSFP28 form factor. This dual port configuration can support designs that require either redundant network paths or multiple high-speed connections from a single server, depending on the broader network architecture.

What connector type should be used with this 100GbE adapter?

The adapter is categorized as a dual port 100 Gigabit QSFP28 device, indicating QSFP28 connectors on each 100GbE port. For deployment, cabling and transceivers must match the QSFP28 form factor to establish 100GbE links. This is important when aligning the adapter with switch ports and existing 100GbE optical or direct attach cable inventories.
