[lustre-discuss] Do I need Lustre?

[Brett Lee]

Hi Neil,

One of the considerations in using Lustre should be the I/O patterns of
your applications.  Lustre excels with large, sequential reads and writes.

Another are the costs, to include hardware, software, support, and coming
up to speed with Lustre.  These components interact.  For example, having
professional support helps with coming up to speed on Lustre. :)

Hey Michael!
