The following series implements Intel I/O Acceleration Technology (I/ OAT) support for open-iscsi. This series works on the 2.6.24.x kernels. We are working on modifying the patches to work with the new tcp recv path in open-iscsi from the 2.6.25-rcx kernels. I recommend using the latest stable 2.6.24 kernel to apply the patches. We're putting these out now to solicit feedback from the community, and will submit new patches against the upstream open-iscsi kernel. Please feel free to send any comments/suggestions to me or the list. We also continue to work on performance tuning these patches. Each patch in this series has additional descriptive notes. Please apply the patches in the order 01-tcp_dma, 02-networking, 03-iscsibase, and 04- iscsioffload. I have just applied these patches using stg on the stable version of kernel 2.6.24.4 from git.kernel.org successfully. Please let me know if for some reason these don't apply cleanly for you.
The following additional features may need to be enabled in .config by the user if not active by default by running "make menuconfig." 1. Under "Device Drivers" enable DMA Engine Support, and Intel I/OAT. 2. Under "Device Drivers" enable SCSI low level drivers support and the iSCSI initiator over TCP/IP. To enable the features in the patches, please ensure that the "ioatdma" module is loaded using "modprobe ioatdma." We noticed a marginal increase in throughput using Intel 1Gb ethernet cards (e1000) and a significant increase in throughput using the Intel 10Gb cards. NOTE: THIS SERIES WILL ONLY COMPILE ON THE 2.6.24.X KERNELS AND NOT THE LATEST (2.6.25-RCx)UPSTREAM KERNELS. -- Supreeth Venkataraman --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
