Anthony,
I would agree with everything Fuad has already expressed in his email. I'm
also adding my comments below; hope they help.
1. How does it perform?
The ODA is an engineered system. Oracle has designed it to perform pretty
well. Using I/O Calibration in testing an ODA I have seen a great deal if
IOPs pushed through the system. Overall performance will be based on you
database logical architecture and application requirements for access the
data.
2. Does it meet your expectations?
Everyone's expectations vary based on what the end usage of the ODA is for.
Customers where I have installed them, love them for the speed and compact
design. When it comes to expectations of installations, the ODA can be up
and running within a few hours.
3. Was it as quick to setup as Oracle says? How long to setup in your
shop?
Setup times vary depending what experience you have in setting up an ODA.
From bare-metal to functioning database, I've seen it between 4-6 hours (no
data). Importing your data; the timing will vary depending on the method to
move the data. For real-time migrations, would recommend GoldenGate;
outside of that Export/Import works pretty well.
4. How seamless is patching through the appliance manager?
What type of patching? There is ODA specific patching and there is normal
database patching. I know most customers I've talked with usually wait for
ODA specific patch to make the process easy. For an additional cost, Oracle
will do the patching for you.
5. How frequently are you replacing disks?
I can't really tell you how often disks will be replaced because I've only
installed them for customers. After I leave a site, it is up to the client
to monitor and replace when needed.
6. Quality of support from oracle on appliance issues?
Quality of service for engineered systems has been pretty good in my
experience.
7. gotchas?
The gotchas are the reason why myself and a few other authors (including
Fuad) decided to publish a book by Apress called the Practical Oracle
Database Appliance. When we decided to write the book, it was to give
users, like yourself, the knowledge to understand and work around the
gotchas. I'm sure this will come off as a shameless plug, but that is the
real reason why the authors of the book wrote it.

I hope this answers all your questions. If you need anything else feel free
to ask.

Anthony .
I've implemented about 50+ ODA's in the last 2 years for my previous company
and can definitely speak to some of the things that you ask,
1. how does it perform?
Performs pretty darn good but it depends on your db usage
Does it meet your expectations?
If there is a right design and understanding yes it did
Was it as quick to setup as Oracle says? How long to setup in your shop?
from plug in to db there in 4 hrs was my first experience . We had 4 ODA's
up in 3 days . here was a blog post that i did

How seamless is patching through the appliance manager?
The patching is seamless but does require downtime in some cases
How frequently are you replacing disks?
It seems like its been varied i've had a couple of ODA's where we had no
disk replacements for a whole year and a couple where we had 2 disk
replacements in a year.
Quality of support from oracle on appliance issues?
Pretty good and a one stop shop support
gotchas?
Look for the IOPS. if you have an I/O bound application make sure it scales
within the realm of the ODA. ODA is limited to Disk on the ODA and one
storage expansion. Make sure you look at your growth patterns accordingly.
And last a plug for our book that Just came out on the ODA.

Subject: Oracle database appliance X4-2
Hi folks,
We are looking to move a virtualized, memory and IO bound database from
vmware to a physical machine with dedicated storage. We are considering the
Oracle database appliance X4-2 (bare metal, no oracle vm, RAC).
current env:
vmware 5
RH 5.9
Oracle 11.2.0.3 with partitioning and advanced compression
~800GB
HP Left Hand San P4000 (three of them, RAID 10)
oracle license tied to an app with NO cpu restrictions
small overworked infrastructure team tired of hearing me complain about
performance
IO is currently our biggest issue as our SAN is not quite enterprise level
and is heavily abused, especially by this db server. We are currently
seeing ~30 millisecond latency on average. There are 35 vm's sitting on
this SAN.
I'd like to know if any other folks out there have any experience with this
hardware and if so,
how does it perform?
Does it meet your expectations?
Was it as quick to setup as Oracle says? How long to setup in your shop?
How seamless is patching through the appliance manager?
How frequently are you replacing disks?
Quality of support from oracle on appliance issues?
gotchas?
etc, etc
Any feedback would be most appreciated.
thanks!
Anthony
