Ed, See my answers inline:
"I don't think your question is clear. What do you mean "on oracle backed by storage luns?"" We'll be using luns from a storage array vs ZFS controller disks. The luns are mapped the db server and from there initialize under ZFS. " Do you mean "on oracle hardware?" " On Sun/Oracle x86 hardware "Do you mean you plan to run oracle database on the server, with ZFS under the database? " Yes Generally speaking, you can enable compression on any zfs filesystem, and the cpu overhead is not very big, and the compression level is not very strong by default. However, if the data you have is generally uncompressible, any overhead is a waste. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
