RedHat Linux , HP SAN & Oracle-Do we still need Veritas Volume Manager?
Hi,
We are in the process of data migration where we have standardised on the following systems:
1- HP EVA4100 SAN
2- Xeon-based HP servers
3- RedHat Enterprise Linux
4- Oracle database
Now as far as SAN volume management is concerned , do we still need a third party software like Veritas Storage Foundation?
In addition and to provide clustering software for the Oracle database , do we still need Veritas Cluster Server to do that?
In other words , can't we simply have the above two functionalities provided out of the box with the HP SAN and Linux?
Kindly advice
Thanks

Hi,
Yeah this is what I suggest. Because SAN's generally have web interfaces to do the necessary partitioning and assignment. This is what you need now from what I understand what you ask. You only need a product like Veritas Storage Foundation only when you have heterogenous environmensts and say you need to move a Linux volume to an AIX server (iVeritas does the conversion of the filesystems so that AIX can use the volume)
Similarly when you need is a simple cluster of of two systems you can accomplish this by using Oracle Cluster software called RAC (Real Application Cluster. You need Veritas only you have "exotic" requests like using several diffrent unixes and when your main system fails you want to move to another platform!! etc.
Here's a link from Oracle site it just decribes how to setup clustered systems (and naturally an SAN too) for Oracle.

(the Oracle Enterprise Linux they tla ka bout is simply a repacked RHEL 4)
I hope this helps.

But this is not supported by Oracle in production environments!

What about the Veritas Cluster Server? Do we still need it ? We are not going for Oracle RAC (its too expensive)
Kindly advice
