Good afternoon, hope the weekend is going well for everyone.
Izzy the Golden Retriever, on behalf of Enjellic Systems Development,
would like to announce the release of the Xen-SAN system. This is a
package which provides hotplug support and documentation for allowing
Xen DomU guests to participate as first class initiators in a Storage
Area Network (SAN).
The package can be downloaded from the following URL:
ftp://ftp.enjellic.com/pub/xen/Xen-SAN-0.1.0.tar.gz
This implementation provides support for dynamic creation and
termination of SAN connections at the request of the XL toolstack.
The block devices implemented by these connections are exported by the
blkback interface to the guests. This allows storage for Xen guests
to be managed as any other initiator in a SAN environment with the
advantage of the guest requiring no knowledge of SAN implementation
mechanics.
Due to interest in the package and development and testing deadlines
this release contains support only for iSCSI initiators. NPIV support
for fibre-channel SAN''s is under testing and will be included in a
subsequent release.
The package has been tested extensively with the following components:
Xen 4.2.1
open-iscsi 2.0.873
kernel.org Linux 3.4.x Dom0/DomU
SCST 2.2.x target implementation
The goal of the sub-system is to operate as standalone hotplug
scripts. A small modification is required to extend lock coverage in
the ''block'' script. A modified ''block''
script, which has been tested
to function identically to the script released with the Xen sources,
is included. This package WILL NOT function properly with the default
script.
Since development in and function of the Linux/Xen hotplug environment
is best described as ''intrigueing'' we are interested in
feedback on
issues which may exist outside our customized storage and
virtualization environment. Due to the complexity of the sub-systems
involved users are STRONGLY recommended to review the included
documentation.
We hope the open-storage and virtualization communities find this to
be a useful contribution to the eco-system.
