How many ports are available on the HP 448262-B21 adapter?

The adapter is described as a dual-port InfiniBand mezzanine host channel adapter. This indicates that it provides two InfiniBand ports on a single card. Knowing that it is dual-port helps in designing connections to InfiniBand switches and in planning redundancy or multiple fabric links per server.

What is the system interface for the HP 448262-B21?

The HP 448262-B21 is categorized as a 4x DDR dual-port InfiniBand adapter with a PCI Express 2.0 x8 interface. This means it connects to the host system using a PCI Express 2.0 x8 bus. Procurement teams should confirm that their server platforms support PCI Express 2.0 x8 for proper integration.

What form factor does the HP 448262-B21 use?

This product is described as a mezzanine host channel adapter. The mezzanine form factor is intended for compatible servers that accept mezzanine adapters rather than standard add-in cards. Verifying mezzanine support on the target server platform is important before planning deployments with this adapter.

Is the HP 448262-B21 suitable for InfiniBand mezzanine deployments?

Yes, the HP 448262-B21 is defined as an InfiniBand mezzanine host channel adapter with 4x DDR dual-port InfiniBand support. It is intended for use in systems that accept mezzanine HCAs and require InfiniBand connectivity. This makes it relevant for server designs that integrate InfiniBand via mezzanine interfaces.
