<p><b>New page</b></p><div>This page is intended for sites to use as a template in order for them to describe their SRM setup in detail. Obviously, sites can change/alter the format to suit their specific needs, but do not edit '''this''' page! The questions posed below are just to give sites an indication of the sort of information that should go here. Suggestions for additions are welcome and should be sent to [[User:Greig_cowan|Greig]].<br />

== Admin node(s) ==<br />
<br />
DPM headnode is <tt>svr018.gla.scotgrid.ac.uk</tt>. Runs DPM, DPNS and SRM daemons (v1 and v2). Only a small filesystem on this host for testing purposes - usually set to read only.<br />
<br />
== Disk Server(s) ==<br />
<br />
Nine grid disk servers, <tt>disk032-disk041</tt> (but not <tt>disk037</tt>, which is for "local" cluster disk). <br />
<br />
Hardware 22x500GB Hitachi SATA drives connected to an Areca PCI-X card.<br />
<br />
Disk servers are setup as RAID 6 with 1 hot space, so have ~9.5TB of usable space.<br />
<br />
To support the Areca card SLC is used (currently SLC4X, i386).<br />
<br />
== Optimisation ==<br />
<br />
Filesystems are ext2 formatted. Will move to xfs once x86_64 is supported by DPM (see [[Performance and Tuning]]). Having no filesystems on headnode improves transfer reliability.<br />
<br />
== Additional Information ==<br />
<br />
DPM has been a pretty trouble free experience.<br />
