Re: [Gluster-users] When to use striped volumes?

2017-01-17 Thread Dave Fan 
Hi Krutika,


The use-case would be storage for a parallel computing application with high 
concurrency.


How's striping fit into different use-case scenarios? We are targeting other 
applications as well, for example, Hadoop, Virtual Desktop, etc.


My Best,
Dave

Could you describe what use-case you intend to use striping for?

Hello everyone,


We are trying to set up a Gluster-based storage for best performance. On the 
official Gluster website. It says:


Striped – Striped volumes stripes data across bricks in the volume. For best 
results, you should use striped volumes only in high concurrency environments 
accessing very large files.


Is there a rule-of-thumb on what size qualifies as "very large files" here?


Many thanks,
Dave
