Home -> Community -> Mailing Lists -> Oracle-L -> Re:For Dick Goulet - - RE: why SAN ? why not external stor
Brian,
NetApps work just great for archive redo logs, their just an NFS mount. The problem we have had is getting things configured for Datafiles. If your use to a DAS system where you have the server and external disks, you have SCSI or Fiber cables between the two as dedicated connections. With NetApp's you replace those SCSI cables with GB ethernet cables. Not too bad IF the server and NetApp are in the same or adjacent cabinets. BUT when they aren't and your using a network switch and VLAN things get rather messy. I had a datafile out there that went offline once per hour because DBWR did not get some header info back in a "reasonable" timeframe.

Dick ... did you have problems with Netapps on your archivelogs or
just the datafiles or both??
We are considering using it for alternative archivelog solution...
Last place we were at ....we did have a few issue with datafiles but it got worked out and worked fine after that.

Rahul,
We're heading out onto the SAN route as well from the external storage
world. Right now we use a number of HP-UX servers connected to one of two
EMC
symmetrix arrays for datafiles and one of two NetApp Filers for archive redo
logs. They work well, but the EMC's are expensive and every now and then,
like
last year, you end up with a "forklift" upgrade. The NetApps are cheaper
and
are suppose to work for Oracle datafiles, but we've had a myriad of problems
getting it to work. The idea of a SAN is that the actual disks can come
from a
number of vendors and the SAN implementation handles the differences so that
you
& I only see available disk space. And from Oracle's point of view all of
the
disks are local, not remote or NFS mounted or NAS or any of that other weird
stuff out there. I would not classify it as much as a cost, but flexibility
issue.

list, one of our clietns are going to by SAN, the current oracle databases
take
around
36GB of storage.... i dnt understand there reason to go for SAN, i
sugguested to
buy an external storage
box instead. How can i justify my desicion ? (cost of not the factor)
TIA
