Hi Oracle-L,

I'm preparing to install ASM using our EVA storage and I'm trying to decide how many volumes to request from my storage manager.

There are two configurations we consider: 1) Ask for two volumes - one for data files, the other for flashback, archive logs, backups, etc. Then run ASM with external redundancy and external striping. Let EVA do the RAID thing for us. 2) Ask for multiple data volumes and multiple backup volumes. Configure ASM to do its own striping. Since EVA will do its own stripe+mirror thing, we'll have double striping.

I'm leaning toward the first option since it seems more manageable.

Does anyone on the least have a good reason to go with the second option? I'm worried that I'm missing something, because all ASM papers natually assume there will be multiple ASK "disks".
