+===== Old Notes =====
+==== Server Side (Target) ====
+''vblade'' - user space AoE server
+''kvblade'' - kernel space server
+Performance difference?
+[[virtualization:xen_virtualization|Xen Virtualization]] - Mount AoE storage in Dom0 then share to DomU's
+[[Linux Software RAID]] 1 to mirror two RAID 5 arrays
+==== Client Side (Initiator) ====
+Begin discovery of AoE targets:
+<file>
+modprobe aoe
+</file>
+No partition necessary - put filesystem on block device:
+''/dev/etherd/e<shelfnum>.<slotnum>''
+<file>
+mkfs.ext3 /dev/etherd/e0.1
+</file>
+Partitions can be used:
+''/dev/etherd/e0.3p1''
+Custom init script to bring up and shut down AoE storage (FAQ)
+Admin Console uses port 6936
+Install compiler:
+<file>
+yum install gcc gcc-c++ autoconf automake
+</file>
+Install aoetools (domU):
+<file>
+wget http://superb-west.dl.sourceforge.net/sourceforge/aoetools/aoetools-16.tar.gz
+make install
+</file>
+Install vblade (dom0) to export storage:
+<file>
+wget http://internap.dl.sourceforge.net/sourceforge/aoetools/vblade-14.tgz
+make
+make install
+</file>
+<file>
+vi /etc/udev/rules.d/60-aoe.rules
+# These rules tell udev what device nodes to create for [[aoe]] support.
+# They may be installed along the following lines.  Check the section
+# 8 udev manpage to see whether your udev supports SUBSYSTEM, and
+# whether it uses one or two equal signs for SUBSYSTEM and KERNEL.
+# [[aoe]] char devices
+SUBSYSTEM=="[[aoe]]", KERNEL=="discover",   NAME="etherd/%k", GROUP="disk", MODE="0220"
+SUBSYSTEM=="[[aoe]]", KERNEL=="err",        NAME="etherd/%k", GROUP="disk", MODE="0440"
