Hola Lisa,
Imho, the DR requirements argument is rather strong, I would not argue
against that...;-)
You may find the ASM limits here:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/storeman.htm#
sthref1706
I'll copy them for your convenience:
*
63 disk groups in a storage system
*
10,000 ASM disks in a storage system
*
4 petabyte maximum storage for each ASM disk
*
40 exabyte maximum storage for each storage system
*
1 million files for each disk group
*
Maximum files sizes as shown in the following table:
Disk Group Type Maximum File Size
External redundancy 35 TB
Normal redundancy 5.8 TB
High redundancy 3.9 TB
hth (at least a bit:-))
cu,
Torsten.

only limitation I found was that a diskgroup is limited to 10k (or

for this implementation.
> What is the largest number of files you have in ASM (regardless of size)?
