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,

As far as I understand all you want is to attach a SAN volume to your server. It this is it all you need is iSCSI driver for your server to operate your HBA adapter and an SAN with necessary configuration. Veritas Storage Foundation is for complex tasks such as converting a solaris volume to a Linux volume etc.

When it comes to Oracle Cluster Oracle has its own Clustering software and also some support for volumes. You sdont need Veritas there too.

The simple answer to your question is YES. You don't need any extra tools if all you want to do is a simple cluster with a fixed conection to SAN. These veritas products are for hetrogenous environments or data-centers with diverse hardware and/or frequent switching from one platform to another or moving to another system /platform easily.

So you are suggesting that we should be able to create the needed SAN volumes and map them to the Linix OS without Veritas Storage Foundation

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

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.
Cheers,

But this is not supported by Oracle in production environments!
