Would like to know the network configuration on exadata system which the vdb can be mounted using nFS. what is the prerequisites on the target system ( exadata) and which network interface is using to mount the VDB's .
What re the requirements on target exadata machine to mount the VDB's on exadata dbnodes.
Depending on what model Exadata you are supporting, compute nodes are equipped with four to eight (4-8) 1/10GbE network ports. One of these are reserved for management during setup/configuration, but the remainder can be used for client access and other uses such as network-attached storage and NFS.
If Exadata compute nodes are to be used as "targets" for virtual databases from Delphix, then the network configuration should be prepared as for any NFS-based network-attached storage, including the 10 GbE setting (instead of 1 GbE), as documented online here. Additional options for improved performance of network-attached storage include the use of TCP "jumbo frames" as documented online here.
As far as whether Oracle Support has objections to the use of Exadata compute nodes hosting Delphix virtual databases, Oracle Support note #1541428.1 (entitled "Is it acceptable / supported to install additional or 3rd party software on Exadata machines and how to check for conflicts?") should be helpful in clearing that concern.
Hope this helps!
thanks for the reply,
We are using the x2-2 half rack and want to know which network interface we can use.
there are 5 interfaces with 1GB and 2 with 10GB..
Out of 5 1Gb 2 interfaces are free , those are not allocated to any setup for client/management or network storage etc.
and other 2 interfaces with 10G were assigned to Infiniband interfaces to connect storage servers.
Let me know in this case how to configure the nfs , with 10G interfaces, it's already assigned to storage cells.
And also the jumbo frames configuration document was not opening, pls provide the link to access the document.
If you're saying that there are no 10GbE interfaces available for NFS, then as already stated virtual databases use the Delphix Engine appliance as a network-attached storage appliance for all datafiles, tempfiles, online/archived redo logfiles, spfiles, etc, so all of the guidelines for optimizing network-attached storage apply.
You can certainly use 1GbE interfaces for NFS, but expectations for performance of the dependent virtual databases should be adjusted accordingly.
Hope this helps!
