Create indexes - own File Group

[rcamarda]

With help of others on this group, I've been learning and researching
about indexes; an area I neglected.
I see I can specify which filegroup I wish to create an index, which
the default is Primary.
I have more than one drive in my SQL server where I put data and logs
on their own logical raid groups.
My databases are SIMPLE, so they dont use much, if any logs (none as I
understand).
I was thinking of adding an additional file to my database and use it
solely for the indexes.
Any thoughts?

SQL Server 2005 Enterprise x64 SP2
8 disk SAS Raid 1+0 w/ 512mb ram w/ battery backup.
Thanks,
Rob

Yes, I've done this and putting your non-clustered indexes in its own group
can provide an improvement. Especially for rebuilds and the like.

HOWEVER, your database most definitely DOES use the logs. SIMPLE simply
means that as soon as transactions are complete, the log is truncated so it
won't grow. But it is definitely being used.

Keep in mind that w/o logs, you seriously hamper your disaster recovery
options. Since you're running SQL Server Enterprise, that makes me suspect
this is more than just a little test site.

Greg,
Its a data warehouse. I have tools that could rebuild an empty
database pretty quickly (few hours) and I have daily backups. Builds
take about 2 hours, then its read only the rest of the day.
I use enterprise because of our licensing.

Thanks for the info!
