Database Software

Hello Gurus,

I am looking from the cost perspective of implementing RAC. I need you help in this regard and would like to know the cost of implementing it. I know there will be cost related to DBA, Training, Support, etc but as of now I am looking purely from hardware/software stand point.

There will be three RAC environments -

Sandbox - 2 nodes (1CPU and 5GB each)
Test - 3 nodes (2CPU and 5GB each)
Prod - 3 nodes (4 CPU and 15GB each)

Not sure what all things will be required but lets look into all that may be required to configure our sandbox/test/prod environments.

Oracle Database
Oracle RAC
ASM
High Speed Switch or Interconnect
Low Latency Interconnect
Hi-Speed Cluster Interconnect (Hub or Switch Fabric)
Shared Storage
Mirrored Disk Subsystem

I may be missing a lot in the above list so I will let you to add in the list and if possible give a rough estimate.

Thanks for your time!
