I am migrating a site that currently uses raw partitions for their
oracle files. I am wondering if it is true that performance is 20%
higher or if that was only in the early days? What, in your
collective experiences/comparison test, has been the true performance
gain of raw devices?
I am also wondering if anyone has any experience with the Veritas
Database Edition. We have Sun E5000's w/ Volume Manager bundled, but
this is an extra ($$) product. The advantage is that, according to
sun and Veritas, their "Quick I/O" feature offers the ease of using
filesystems and a volume manager with raw-device access speeds.
Anyone had a chance to test this out and how stable do you find the
product. We will be running a 100 to 150GB's worth of oracle
databases on each 5000.
thanks for any input
