    The HP ProLiant Essentials Accelerated iSCSI Pack enables the embedded Multifunction NIC on a ProLiant server to run accelerated iSCSI over IP networks. iSCSI allows block-level storage data to be transported over widely used IP networks, enabling end users to access the storage network from anywhere in the enterprise. Additionally, it offloads the iSCSI function to the NIC rather than taxing the CPU of the server.

    Accelerated iSCSI allows the embedded network controller to multi-function as both a NIC and an HBA, thereby providing access to storage boxes and to servers over a single connection. Additionally, it offloads the iSCSI software to the hardware for improved performance. With the protocol stack processing offloaded to the NIC, it reduces CPU utilization. This sort of offloading can greatly improve the speed with which requests are processed and sent to the network. The process begins when an application sends a request to the operating system (OS) to read or write data. The OS generates the appropriate SCSI commands and data request in the form of a message. Before the message can be sent over an IP network, it is processed through iSCSI to encapsulate the request into the TCP/IP protocol stack (attaching routing, error checking, and control information) for transmission over the network. The HBA (i.e. the network controller) transmits the packets over the IP network. When the packets reach the target device, they go through a reverse process to reassemble (sequence) the data, which is then moved to the SCSI controller. The SCSI controller fulfills the request by writing data to or reading data from the target device. If it is a read transaction, the target returns data to the initiator using the iSCSI protocol.
