Home -> Community -> Mailing Lists -> Oracle-L -> 10g - ASM
Hello all,=20
I'm currently installing 10g on Windows 2003. Anyone using Automatic Storage Management? =20
I read this in the ASM documentation (below), and I'm concerned because a LUN is a logical volume. I wonder if implementing ASM is just an unnecessary pain for a SAN environment, especially considering the enormous SAN cache. =20
Way back when I didn't have grey hair and I worked on Unix, all my devices were logical volumes. That was standard in every Unix shop I worked in. I get the feeling I'm missing something or misinterpreting this paragraph below. It sounds like it wants direct access to disks, period.
I am not a SAN, Unix or Windoze expert. Comments, anyone? =20
Thanks
With Automatic Storage Management, the definition of the logical volumes of a storage array is critical to database performance. Automatic Storage Management cannot optimize database data placement when the storage array disks are subdivided or aggregated. Aggregating and subdividing the physical volumes of an array into logical volumes can hide the physical disk boundaries from Automatic Storage Management. Consequently, careful consideration of storage array configuration is required.
