Re: Appropriate applications for GPFS

Have no experience of running MySQL on GPFS...however, running GPFS is
one of the options to run Oracle RAC recommended by both IBM and
Oracle. Also, GPFS is designed for high performance (according to IBM's
doc). Not done any tunning yet...sorry for not having more to share.

I am happy to be corrected on this, but GPFS (formally multi-media
filesystem)
is designed to support large-block transfers. It isn't designed for
high-speed
metadata performance (databases). I have access to the system now, but
they way funding works, they are going to have to decide on hardware to
purchase before I can do some real testing.

I will run some tests this week to help me decide, but I don't have
time to
install mysql and run tests.

Thanks,
Craig

I have a couple of users that want to move their applications to our
new pSeries 575 cluster and I need to figure out which storage system
to use. We currently have an NFS server and a GPFS filesystem.

1) MySQL database
2) Flat ascii files of tcpdump results

Sorry I cannot give more information at this time, because I don't have
it. But due to internal budget cycles I need to make a guess on what
is best (more GFPS, more NFS, and/or MySQL server with local disk).

My real question is, it is most likely that both of these applications
are metadata intensive. If so, should I avoid using GPFS for them?

Can anyone make an educated guess on the appropriateness of GFPS?

Thanks,
Craig
