How many ports are available on the HP 483512-B21 adapter?

This adapter is described as a dual port InfiniBand 4x DDR PCI-Express host channel adapter. Dual port indicates that two InfiniBand ports are provided on a single card. This allows a host to connect to two separate InfiniBand links or fabrics using the same adapter, subject to system and topology design.

What system bus does the HP 483512-B21 require?

The product is identified as a PCI-Express host channel adapter. This means it must be installed in a compatible PCI-Express slot within the host system. Procurement and engineering teams should confirm that the target servers support PCI-Express adapter cards before planning deployment of this InfiniBand adapter.

What does zero memory mean for the HP 483512-B21 adapter?

The HP 483512-B21 is described as a zero memory host channel adapter. Zero memory indicates the adapter does not provide on-board memory for data offload. Instead, it operates in conjunction with host system resources and software. This characteristic can guide expectations on how the adapter integrates into the overall system architecture.

What type of product is the HP 483512-B21 in network terms?

The HP 483512-B21 is categorized as an InfiniBand 4x DDR dual port PCI-Express zero memory host channel adapter. In network terms, it functions as a host channel adapter, connecting servers or hosts to an InfiniBand fabric using the InfiniBand 4x DDR interface and the PCI-Express system bus.

Product overview

The HP 483512-B21 is an InfiniBand 4x DDR dual port PCI-Express zero memory host channel adapter designed for environments that use InfiniBand interconnects. As a dual port adapter, it provides two InfiniBand 4x DDR interfaces, supporting connectivity where InfiniBand technology is deployed. The PCI-Express form factor allows integration into compatible server or workstation platforms that accept PCI-Express adapter cards. The zero memory host channel adapter design means the adapter does not incorporate on-board memory for offload, aligning it with architectures that rely on host system resources. This product fits into configurations that require an InfiniBand 4x DDR link and dual port capability, while maintaining a straightforward hardware profile. With its combination of InfiniBand 4x DDR, dual port layout, PCI-Express interface, and zero memory architecture, the HP 483512-B21 offers a standardized adapter option for InfiniBand-based infrastructures.
