Frequently asked questions
What Ethernet speeds does the HPE P14485-001 adapter support?
The HPE P14485-001, based on the Intel E810-XXVDA2 controller, supports both 10 Gigabit Ethernet and 25 Gigabit Ethernet. It exposes two SFP28 interfaces that can operate at these speeds, providing flexibility for connecting to either 10GbE or 25GbE capable switches and optics. This allows staged migration to higher bandwidth networks while using the same adapter.
Which form factor and bus interface does this adapter use?
This adapter is implemented as a plug-in card using an Open Compute Project mezzanine 3.0 interface. It is designed for servers that provide an OCP 3.0 mezzanine slot. This integration approach is common in dense data center platforms and differs from traditional PCIe add-in cards, so compatibility with OCP 3.0 slots is required.
How many network ports are available on the HPE Intel E810-XXVDA2 adapter?
The adapter provides two network ports using SFP28 interfaces. These ports support both 10 Gigabit Ethernet and 25 Gigabit Ethernet data link protocols. Dual-port design enables link aggregation, separation of traffic types, or redundancy strategies, depending on how network administrators choose to cable and configure the connections.
What is the typical power consumption of this OCP 3.0 adapter?
The specified operational power consumption for this network adapter is 8.9 watts. This figure allows data center planners to include the adapter accurately in rack-level power and cooling calculations. Knowing the adapter’s power draw is particularly important in high-density deployments where many OCP 3.0 adapters may be installed in a single rack.
Which network and transport protocols are supported?
The adapter supports standard data link protocols for 10 Gigabit Ethernet and 25 Gigabit Ethernet, along with network and transport protocols such as TCP or IP, iSCSI, and iWARP. This enables use in general IP networking, IP-based storage environments that rely on iSCSI, and low-latency transport scenarios leveraging iWARP capabilities.
What virtualization features does the adapter provide?
Virtualization-related features include Receive Side Scaling, Single Root I or O Virtualization, VMQueue, Network Partitioning, and support for Data Plane Development Kit. These capabilities are designed to improve multi-queue performance, enable efficient virtual machine networking, and allow fine-grained partitioning of adapter resources between workloads.
Does the adapter support network overlay and tunneling technologies?
Yes, the adapter supports several overlay and tunneling features, including Virtual Extensible LAN, Network Virtualization using Generic Routing Encapsulation, GENEVE, and tunnel offload. These features help integrate the adapter into software-defined and virtualized network architectures where encapsulated traffic is used extensively.
