The HP NC380T PCI Express Dual Port Multifunction Gigabit Server Adapter is the industry's first PCI Express dual port multifunction network adapter supporting TOE (TCP/IP Offload Engine) for Windows only, Internet Small Computer Serial Interface (iSCSI), and RDMA (Remote Direct Memory Access) over a single network connection.

Because each port on the NC380T supports multiple functions, it can assume any defined networking role:
- As a TOE device for Windows only, the NC380T shifts processing of the communications protocol stack (TCP/IP) from the server CPU to the network adapter (also known as a NIC), thereby freeing CPU cycles for other duties. With TOE, network communications are improved, and server efficiency is increased.
- As an iSCSI HBA, the NC380T combines two well-known technologies, SCSI and Ethernet, to give HP ProLiant servers ready access to storage boxes over the same wire used for networking. Accelerated iSCSI gives the NC380T block storage access over TCP/IP. iSCSI enables the NC380T to function as both a NIC and an HBA from a single connection. This capability is valuable when you want to consolidate resources and simplify your infrastructure with a single I/O device.
- As a high-speed, low-latency multifunction network adapter, the NC380T provides the fastest communication between two RDMA-capable systems by providing memory to memory communications between servers so that data from the memory of one computer can communicate directly into the memory of another with minimal CPU and memory overhead.

Ideal for...
Resource-constrained customers wanting greater server efficiencies
- The NC380T increases the efficient use of TCP offload resources for Windows only, making sure that the connections dynamically move between host and NIC, depending upon workload
- With TCP/IP Offload Engine (TOE) for Windows only, the NC380T reduces the CPU cycles required to process network traffic in Windows environments
- By using Receive Side Scaling in multiple CPU systems, network traffic is no longer bottlenecked because the NC380T supports dynamic load balancing of incoming traffic across CPUs
Corporate data centers looking to simplify their operations
- When the NC380T is deployed as an iSCSI initiator, it functions as an HBA with accelerated performance for access to individual storage devices and SANs
- The flexibility of the NC380T enables IT staffs to simplify their management operations by having a single I/O device provide both networking and storage needs
- By providing unified networking and storage connections, the NC380T enables the deployment of a single fabric environment
Enterprise customers requiring the highest in performance networking
- Remote Direct Memory Access (RDMA) functionality is a high speed, low latency protocol supported as an add-on capability to the NC380T for direct memory to memory transfer of data
- Applications currently constrained by memory, CPU, or networking throughput will gain the most from RDMA-enabled NC380T because it makes application scaling a reality
- Clustered servers will benefit from the optimized performance of RDMA when the NC380T is used as a cluster interconnect
