I know there has recently been a flurry of mails regarding Oracle on a
filer but is anyone running Informix on one? I ask because there are
alot of issues with the whole Informix/Onbar kludge that we are running
into in an effort to evaluate this.
Netapp has been involved in the preliminary discussions and will be in
the future as well but I wanted to get an idea from real people in the
real world as to the problems you solved and others you ran into.
Here's a primer of what we think are the benefits:
1) snapshots - much faster than tape backup, takes minimal disk space
2) snapmirror - easy DR
3) snaprestore - fast recovery from an archive (snapshot) for testing
and/or devel
4) snapvault - able to take snapshots every 5 minutes (avoid logical
logs altogether) and migrate them to R100, increased retention period
due to minimal space requirements
5) system recovery - data resides on filer so cpu becomes a FRU
Here are a couple of issues/questions regarding the above:
Can all Informix data (i.e., database, binaries, etc.) reside on nfs
leaving only system files on the cpu (i.e. system, services, vfstab)?
Can snapshots every 5 minutes really replace logical logs if 5 minutes
is an acceptable point-in-time recovery period?
Can snapshots be used to get a reliable backup without quiescing the
database?
In the event that logical logs are still required we would write them
to mirrored internal drives. Has anyone managed to write these logs to
nfs?
Thanks.
