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.  

> However, one limitation has been placed on me: the size of the files
presented to ASM will be limited to 33G due to DR requirements.  

> I can't find the limit to the total number of files ASM can manage. The
only limitation I found was that a diskgroup is limited to 10k (or

> was it 1k?) files - probably more than I will manage in the next few years
for this implementation.  

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