Is a V490 adequate hardware for Oracle 11g

We are running Oracle 10 on a V490 and it is running OK.  When we upgrade to oracle 11 running the same systems and same workload are we likely to have performance problems?  I guess another way to look at it is does Oracle 11 require much more horsepower than oracle 10 for the same amount of work?

All Oracle documentation can be found at:
http://www.oracle.com/pls/db112/portal.all_books

Choose the Installation Guide you wish.

As long as your system meets the minimum requirements and depending on what specific features of Oracle you are using, it should be at least as fast.

I do a lot with XML in Oracle and performance increased for me substantially moving to 11g.  I've seen some posts on Experts-Exchange where some people saw slower performance.

11g has a LOT of new features related to performance.  You will need to familiarize yourself with them to take advantage of 11g.

For example:  Automatic Memory Management is even better in 11g.  Basically just two parameters to manage Memory.

After all that:  If you can get more memory/disks, I'm sure Oracle would take full advantage of it.

Those are windows requirements.  I should have been more clear - this is a SunFire V490 running Solaris 10 and currently Oracle 10.  We are going to upgrade to Solaris 10 and Oracle 11.   I'm not the Server admin or the DB admin but for "reasons" that I won't go into I'm being asked to determine if a server upgrade is needed in order to perform this upgrade.  I don't know where to start.  Do you have a corresponding link for Solaris servers like the one for windows?
