Hi,
in addition to the discussion about how to lay out the oracle databases within our without vsphere files I have spotted another thing:
I would strongly recommend to put only oracle binaries and oracle test databases on SATA disks. Do not put any other oracle data on SATA. We have experienced performance issues with SATA disks on our FAS6070 (with PAM-I card). In my opinion, SATA throughput is not suitable for productive databases -regardless of accessing the oracle database within vmdk-files or within dedicated volumes via NFS/iSCSI/FCP.

Hi Im setting a new Oracle Database solution to replace a old Oracle RAC on EVA8400. After reading Oracle Databases on VMware vSphere 4 - Essential Deployment Tips i got a few question still needs answered. Our new storage is a FAS 3240 7-Mode We have a SATA and SAS aggregate and 1TB Flash cache available. SAS 1 Raid Group (16 disks) SATA 4 Raid Group (56 disks)
Whats the recommendations for Datastores and VMDK's?
From i can gather i need to create a volume dedicated to Oracle and present(NFS) it as Datastore for Oracle only.
And create VMDK's like this:
VMDK-1 OS from another Datastore
Oracle Datastore VMDK-2 Oracle Binaries VMDK-3 Oracle data VMDK-4 Oracle Redo VMDK-5 Oracle Archivelogs
I have 5 databases so 5 VM's where i create a volume with Datastore for each?
Would like input from the list how others have done it.
