Home -> Community -> Mailing Lists -> Oracle-L -> Re: Oracle and NAS storage systems
Dick,
We're using Netapp F720's to store all our datafiles (production and test) in a small/medium OLTP environment and are quite happy with the setup. YMMV.
We run out of two sets of collocated servers. At each collocation there are at least two filers and at least two servers. The filers and the servers currently have three 100BaseT network connections. One front channel and two back channels. Each LAN segment is switched. Thus any server at a location can connect to any filer at that location. Datafiles can be spread across filers or spread across channels as performance requires.
The WAFL does indeed write to the nearest available inode and relinks the inode map. The unlinked inode is immediately available for rewrite unless it is a member of a snapshot. Thus while reserving unlinked blocks is inefficient from a storage perspective, it is a factor you get to control by controlling the snapshots.
