If they are all going through the same controller you will still have a problem. Assuming you have multiple controllers you may want to address the next issue, availability. What is the configuration of the disk under /oradata (RAID 0,1,5...)? This is just as important. If you are lucky, Tim Gorman or Mathew Zito will reply to this post and tell you everything you ever needed to know about disk storage. HTH, Mike "Mark W.

Baarf. -----Original Message----- From: oracle-l-bounce@freelists.org [mailto:oracle-l-bounce@freelists.org]On Behalf Of Jose Luis Delgado Sent: Wednesday, July 14, 2004 1:54 PM To: oracle-l@freelists.org Subject: Oracle on SAN recommendation... List! I would like to receive a bit of help on this: (SunOS 5.8, Oracle 8.1.7) We have a SAN solution from EMC, they created several filesystems, one of them is named: /oradata That filesystem, was left for Oracle data only. Five databases were created for an external dba, ALL the datafiles, controlfiles and redolog files were placed in the same structure, i.e: /oradata//datafiles and controlfiles and redologfiles (not yet in archive log mode). EMC argue that, since the filesystem was created from several separate physical disks, they form a 'LOGICAL' disk, and there shouldn't be a problem with contention (due to implicit distribution of data) or something else. Is that ok? Please, can you elaborate on this? Thanks in advance! JL __________________________________ Do you Yahoo!? New and Improved Yahoo!
