Apologies for that. My mobile exchange email client has a like button you can tap in the email action menu. I just discovered it this morning accidentally and thought “wonder what this does. Better push it to find out.” Nothing happened or so I thought. Apparently all it does is make you look like a moron on public mailing lists. Doh!

Hi PMB



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.

Subject: [EXTERNAL] [gpfsug-discuss] GPFS best practises : end user standpoint



Hi all GPFS-gurus !



We (hardly) try to train our users in order to improve how they use storage.



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 ?

I’m talking about very basic rules such as max number of files / subdir into a directory.



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 ?



Thanks for your advices,

PMB
