Mounting multiple TRANS_DIR's on a single VM, Hosting mutiple SAP Instances

[Former Member]

I'm looking for the best practices on mounting mutiple SAP TRAN DIR's on a single VM ,hosting 3 SAP instances, SRM 7, MDM 7and GTS 7. This will be on a Windows 2003 OS with SQL 2008.

Option 1:

One NAS MOUNT with one Drive letter with mutiple SAP Tran Dir's underneath it:

example:

R:\SRM\USR|SAP\TRANS

\MDM\USR|SAP\TRANS

\GTS\USR\SAP\TRANS

Modify the DIR_TRANS in RZ10 to relflect the parameters above

Option 2:

Mutiple NAS mounts with mutiple Drive letters with one SAP TRANS DIR on each:

example:

R:\USR\SAP\TRANS -> SRM

S:\USR\SAP\TRANS -> MDM

T:\USR\SAP\TRANS -> GTS

Thanks

Hi,

i dont think putting all the transport dirs in one drive or different drive will have much performance difference.

Consider space availability also that if you put all the 3 transport dirs in same drive then it might create space issues for you later. but if you have ample space available then have all the three transport dirs in same drive.

And make other drives for backups and other DB stuffs.

Let us know what decision you take.

Cheers!!!

Hi,

Both options will work.

But performance point of view "OPTION - 2" is more suitable as those mount points will be on different physical partitions.

So you will get best DISK PERFORMANCE.

Hi,

I would suggest you to go with the option 2
