AW: ASM # of Files

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.
