AMCC builds on established 3ware SATA RAID leadership to introduce the 3ware 9690SA SAS controller, the new standard in Serial Attached SCSI RAID. As SATA and SAS technologies converge, users look to 3ware SATA for price and performance and to SAS for SAS/SATA connectivity with expansion up to 128 devices. High-Performance Serial Attached SCSI (SAS) RAID Controller AMCC’s 3ware 9690SA SAS/SATA hardware RAID controllers deliver industry-leading RAID 6 and RAID 5 Highlights performance, expanded scalability, robust fault tolerance, and multi-terabyte capacities.

Abstract

This document describes how to set up AMCC PPC 440 based systemsrunning DENX Linux for SAN applications over iSCSI transport.

It explains the process of setting up the iSCSI target and initiatorto use RAID arrays created on 'katmai' (440SPe) and 'taishan' (440GX)boards as SAN appliances.

Building the iSCSI target and initiator kernel components (includedinto the release tarballs) require the access to the kernel sourcetree.

Configuring and building target components:

For the target, the linux-2.6-denx tree was used, version 2.6.21-rc3

  1. Build the target kernel
    The following options should be enabled: For a LSI SAS controller: For Linux RAID support: Also, enable the SCSI disk option.
    Note: Make sure to disable the CONFIG_DEBUG_MUTEXES option.
    • katmai_iscsi.config: iSCSI kernel configuration for 'katmai' board
    • taishan_iscsi.config: iSCSI kernel configuration for 'taishan' board
    • uImage_katmai_iscsi: Linux kernel image for 'katmai' board
    • uImage_taishan_iscsi: Linux kernel image for 'taishan' board
  1. Build the iSCSI Target software (IET):
    • Download the iscsitarget-0.4.14.tar.gz tarball from http://iscsitarget.sourceforge.net
    • Unpack and apply patches:
      • compat-2.6.14-2.6.18.patch - apply with '-R' switch.
    • Build:
    • Install (being root)
  2. Configure the iscsitarget. Edit /opt/eldk-4.1/ppc_4xx/etc/ietd.conf . Set the target name appropriately. It may be left unchanged, though. For this example, the target name was set to the following: Edit the following string to set the 'Lun' to be the Linux RAID device:
  3. Boot the target. Note the LSI SAS device and connected discs are recognized:
  4. On the target, create the RAID5 array using the 'mdadm' utility:
  5. Start the iSCSI target service:

Building and configuring the iSCSI Initiator

In this example, a standard PC running Fedora Core 5 Linux was used as hostsystem.

Note: We also tried to use the iscsi-initiator-utils packagefrom the Fedora Core 6 distribution to set up the iSCSI initiator ona Fedora Core 6 host. This package contains only user-levelcomponents; kernel modules used are from the mainline Fedora Core 6kernel. Such a combination did not work in our tests; the target getsdiscovered but doesn't appear as a local SCSI virtual drive. We endedup with the iscsi_tcp module stuck and being unloadable from thekernel, so we had to reboot the system.

There is note athttp://www.open-iscsi.org/cgi-bin/wiki.pl/Supported_Kernels thatkernel mainline modules should not be used, so we downloaded and builtthe package:

  1. Download open-iscsi-2.0-754.tar.gz from http://www.open-iscsi.org/
  2. Unpack and build:
  3. Install (being root)
  4. Create the following file:
  5. Start the initiator (being root)
  6. By default, the initiator is not configured for auto-connect the target. To automate the discovery/login, see open-iscsi-2.0-754/README
    First, run the discovery process (192.168.80.17 is the IP address of the 'taishan' board): Login (connect) to the discovered target: After this, you should be able to find the virtual appliance in /proc/scsi/scsi: Examine 'dmesg' output for the virtual disk name to use:
  7. Partition, format and mount the disk:
  8. After use, unmount the virtual disk and disconnect from the target:

Here you can find aa tarball with daemon, utilities, kernel modules andconfiguration files as used for this demo.It works both on katmai and taishan.
