Re: Redo Log Placement - RAID 10 ok?

I think you are saying redo instead on undo.    

  800GB/day is quite a lot. It depends on whether   your i/o subsystem can sustain this throughput. This can be found out from the storage \ vendor.    

  Secondly the redo write rate depends at the rate at which the application commits. Batch \ commits are much better.    

  Another option is trying use use unrecoverable loads, with   selective backup of tablespaces maybe by using split mirror.    

  RAID 10 is recommended. For this redo rate, it is better to allocate   separate set of disks only for redo.
