Back to Basics, Storage meets Performance

Two good back to basic items:

Distinguishing RAID 1+0 and 0+1


using autobackup for your control files.

Storage and Performance

EMC is replacing some hard drives with solid state disks in its high-end Symetrix systems. This is very good news for Oracle performance jockeys. There are several approaches I could think of off-hand for making use of this resource. Large enterprise systems have often used the expensive solid state disks as a last resort for handling massive transaction loads. As the prices glide downward we may see time sensitive areas of memory like redo move to solid state disks in more of the small and medium sized systems now using SAN/RAID for everything.
