I was wondering whether this kind of mirroring can be done with ASM alone.
Since this does not seem to be the case, I will probably use a SAN-controller at each site,
giving me many small RAID1 volumes and then do the site mirroring and striping in ASM.
Are there any disadvantages going this way (other than having to pay for the two SAN-controllers)?
