8 (DDP) where the hardware handles the expensive byte touching operations, such
9 as CRC computation and verification, and direct DMA to the final host memory
14 On transmitting, Chelsio S3 h/w computes and inserts the Header and
15 Data digest into the PDUs.
16 On receiving, Chelsio S3 h/w computes and verifies the Header and
17 Data digest of the PDUs.
21 S3 h/w can directly place the iSCSI Data-In or Data-Out PDU's
23 on the Initiator Task Tag (ITT) in Data-In or Target Task Tag (TTT)
28 On transmitting, S3 h/w accepts the complete PDU (header + data)
29 from the host driver, computes and inserts the digests, decomposes
30 the PDU into multiple TCP segments if necessary, and transmit all
31 the TCP segments onto the wire. It handles TCP retransmission if
34 On receiving, S3 h/w recovers the iSCSI PDU by reassembling TCP
35 segments, separating the header and data, calculating and verifying
36 the digests, then forwarding the header to the host. The payload data,
37 if possible, will be directly placed into the pre-posted host DDP
38 buffer. Otherwise, the payload data will be sent to the host too.
40 The cxgb3i driver interfaces with open-iscsi initiator and provides the iSCSI
43 Using the cxgb3i Driver
46 The following steps need to be taken to accelerates the open-iscsi initiator:
48 1. Load the cxgb3i driver: "modprobe cxgb3i"
52 * in the case of recompiling the kernel, the cxgb3i selection is located at
58 2. Create an interface file located under /etc/iscsi/ifaces/ for the new
61 The content of the file should be in the following format:
66 * if iface.ipaddress is specified, <iscsi ip address> needs to be either the
67 same as the ethX's ip address or an address on the same subnet. Make
68 sure the ip address is unique in the network.
77 too big. A error message in the format of
82 "-I <iface file name>" option needs to be specified with most of the
83 iscsiadm command. <iface file name> is the transport interface file created
