Yes we did. I don't remember that it was a package deal. I do remember
that we had a Dell server contract at the time but got an exception to
buy a fully configured 2 node HP RAC solution. It wasn't HP Unix
though. Windows 2000 Server at the time on HP servers.

Did you have HP servers connecting to the HP SAN?
I had a hardware consultant tell me the other day that HP-UX does not
support asynch IO except on raw devices. I am curious if that is a true
statement.

We bought an HP SAN a few years ago which was our first one. We
are a
Windows Server shop. Two bad things happened. We bought the
business
copy option for about 60 or 80k and found out later that it
couldn't
handle all aspects of the Oracle File System. We wanted to
automate this
and take cold backups of our data warehouse. We wanted to create
a new
lun and assign it a drive letter and found out there was no way
to
automate it. You had to manually get in there to assign a new
drive
letter. So, somehow, a major feature which was one of the
deciding
features that steered us to buying it was totally lost.
The second thing was that parts became unavailable a lot sooner
than we
thought. It was a pretty significant purchase for us, about
200k, and we
thought we would be able to use the thing for a long time. So,
make
sure you know exactly how long this thing needs to run and how
long
parts are going to be available. Stock up on drives. Don't
assume that
in three years you will be able to add another cabinet and
drives. They
won't be available.
Otherwise I wasn't too unhappy with it. At first it was the
magic box.
We added too many databases to it and found out the hard way
what
happens when you do that. Now we know. The support was very
good the
first 3 years. They offered 24X7 monitoring and a couple of
times
called us to tell us they were sending parts or people to fix it
before
we knew we had a problem.

Subject: SAN evaluation
We have just begun the process of evaluating a new SAN vendor.
We are
presently developing a list of criteria/requirements/questions
for the
new vendor. So far we have come up with the following:
1. What is their I/O speed.
2. What kind of SAN replication options do they offer.
3. Presently we are using RAID 5. I would like to move to RAID
0+1.
What do they recommend?
4. Does their product have any Oracle related features. For
example, I
know that HP has a SAN developed specifically for an Oracle
warehouse.
Does their product have any bells and whistles for RAC, Streams,
etc.
Has anyone gone through a similar exercise where they had to
evaluate a
SAN vendor? If so, could you share your thoughts with the list?
Thanks,
Tom
