I'd also ask myself am I 'evaluating' RAC in which case presumably = whatever
hardware you can lay your hands on will be fine, or am I 'testing' RAC = in
which case I'd suggest that you need to purchase the same hardware as = you
would be using in a live environment, which would most likely be (I = guess)
blades from one vendor.=20

Chinedu/Chandra,

Although I agree that you can use different OEM vendors as long as the = OS is
the same, be aware of the increased chances for some cross-vendor = problems.
You necessarily don't want finger-pointing between vendors when problems occur (they will!) in a complex RAC environment.
=20

Chinedu, before you launch into using/testing RAC, you should (or ITS should) ask itself the question 'Do I need RAC?'. Mogens N=F8rgaard, a = guru
from this list has an excellent article in IOUG's SELECT magazine on = this
topic. If you don't have IOUG membership, maybe Shell ITS can get one. Alternately, you may ask Mogens for a copy.

1. Yes, you can use nodes from different OEM vendors for RAC.=20
2. You will for sure need a private network or interconnect between the nodes for maintaining the heart-beat.=20

  Hello,
  =20
  I have been asked to setup a test environment for RAC. However, I don't = know so much about hardware. =20
  =20
  My questions may appear dumb, please take no offence, I'm a beginning = DBA and I really want to know.=20
  =20
3. Can I use 2 nodes of different makes (one IBM and one Compaq), but = using same Oracle and OS versions (9.2.0.4 & Linux respectively)?
4. Can I set RAC up, using only the public network?
  =20
  Thanks in advance
  =20
