RE: Hardware for RAC?
Title: Message 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.

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. Chinedu, before you launch into using/testing RAC, you should (or ITS should) ask itself the question 'Do I need RAC?'. Mogens Nørgaard, a gurufrom 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.

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

Hello, I have been asked to setup a test environment forRAC.However, I don't know so much about hardware. My questions may appear dumb, please take no offence, I'm a beginning DBA and I really want to know. 1. Can I use 2 nodes of different makes (one IBM and one Compaq), but using same Oracleand OS versions (9.2.0.4 Linux respectively)? 2. Can I set RAC up, using only the public network? Thanks in advance Regards Chinedu
