RAC interview questions

user8803475Nov 17 2009 — edited May 8 2010

Project:

The installation is on "Oracle Enterprise Linux 5.2 x86_64" and Oracle RAC 10GR2 on IBM x3850 M2 Servers and IBM N-Series storage connected via
redundant Fibre-channel switches. They want to use ASM for disk handling.

Questions are:
1. How many voting disks do we need per cluster (considering we have a redundant Fibre-channel connections)?

2. How many OCR disks do we need and what is the recommended access (OCFS2 or RAW)?

3. How do we calculate the bandwidth needed for the cluster interconnect? We currently have configured 2 x 1Gbit Ethernet ports for this.

Any thoughts?
Thanks
