<p class="MsoNormal"><span style="font-size:12.0pt">This is one of the areas where even the most experienced admins struggle. There is no single answer here. Much of it depends on your particular use case and the file system layout, storage choices, block sizes
all go together. IBM has started to provide some templates for this (the one out is for Genomics) but much is left to do. If you could share some details on the overall user environment and data myself and others could offer some ideas.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody">We (hardly) try to train our users in order to improve how they use storage.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody">I found a lot of best practices on how to configure GPFS from the admin point of view but is there any documentation about how to best user a parallel filesystem like GPFS ?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody">I’m talking about very basic rules such as max number of files / subdir into a directory.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody">I know this is closely related to the FS and storage configuration but there may exist some common rules in order to achieve the best scalabilty, right ?<o:p></o:p></span></p>
