Hi,
I was given following task - have to reinstall two node Oracle 11g Database Standart Edition RAC with shared ASM storage attached via FibreChannel. I am quite new to RAC and AMS  Previous instance crashed due to both controllers hardware failure. I have recovered database and put into production to another server. The database size is around 300GB and expected to grow to 600GB in next ~5 years. Database is combined OLTP and OLAP (high amount of small transactions inserts/updates on current data, while archiving processed data for ever and allowing analytics over whole archive).
I have follwing hardware available:
2x db server 8 core Intel CPU, 12GB RAM, with FC
1x FC storage with 10x 300GB SAS 15k rpm
1x NFS storage 6x 1TB SATA, RAID 5, connected over 1GBit ethernet
Previously the NFS was used for exports (no rman backups) and storage was single 9x300GB RAID 5 split into 3 volumes - crs, racdb and fra. Fail of year.
Now I want to create new setup as below:
2x 300GB - mirror ~ 300GB space for cluster storage (crs) and database redo logs
2x 300GB - mirror ~ 300GB space for undo and temporary tablespaces
6x 300GB - raid10 ~ 900GB space for database user data
NFS - 6TB - fast recovery area - archive logs and rman backups
Please give me any comments and suggestion for new setup.
Thanks a lot !
