Oracle RAC with Equallogic replication

Hello all,

We will be implimenting an Oracle RAC cluster with Red Hal Linux on Equallogic storage.  There will also an identical DR location.

I have found plenty of documentation for configuring Oracle, Redhat and the Equallogic, but I am having trouble finding documentation and best practices regarding the DR location.

I am unfamilar with Oracle so i guess my questions are relating more around how the design should be so that Oracle will function.

in the DR Site, should the servers be the Same IP addresses as the production site, or should they be a different network all together?  Is Oracle okay with using Equallogic replication, or does it require a different type of replication?

I appologize for not being able to provide specific information as I dont have a lot of it.  I am assuming the latest version of RHEL, Oracle RAC, and Equallogic firmware v. 5.0.4

Thanks!

I'm not too familiar with Equalogic's offerings in terms of replication/DR but...

Unless you have specific needs for the array-based repliation (low latency FC, FC frame compression, SRDF, etc) - Then I would use Oracle's replication product.

Just carve up LUNs at the DR site and use Oracle Data Guard to replicate.
The IPs don't really matter.

Sorry for the late reply.  I just found out that DataGuard from Oracle isnt an option becuase they arent licensed for it.  So it looks like I will have to depend on the SAN replication.

In the DR site, since the volume will be offline then brought online in a DR test or cutover, do you  have any recommendations regarding this?  Would I be okay with the servers in DR having different IP's and names than the production servers?

Thanks!

Oracle's replication product was used for the replication becuase it is cable of synchronis replication but the Equallogic is only capable of asynchronis replication.

Thanks!
