Accelerated iSCSI
Accelerated iSCSI Pack for Embedded Multifunction Server Adapters enables the embedded network
controller's iSCSI offload engine (for the supported operating systems) thereby providing access to
storage boxes and to servers over a single connection.
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 network adapter, functioning as an HBA, 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.

iSCSI enables improvements in the economics, operating distance, and manageability of storage
networks. iSCSI also leverages the security capabilities of IP networks.
