Experiences with Sun T2000 servers on SAP systems

[Former Member]

Hello,

We are currently involved in a project to migrate our SAP systems from a Windows 2003 to a Solaris 10 platform. Our application server layer will be based on Sun T2000 servers for both ABAP and Java stacks.

I would be interested in hearing from anyone using T2000s in the application server layer to understand their perception of the performance of these systems.

Thanks in advance,

Hi,

Thanks for the comments - we will flag this up and see how the project wants to proceed.

We have actually solved the issues sourrounding performance on sun multi threaded servers.

What you need to do is create a 'Zone' on the solaris server and then allocate resources to the zone.

Then sap seems to fly.

This is fully supported by the way.

Just set this up with NW7 on a T2000 and some T5120's

Basically what occurs is that you setup SAP on one zone.

You then allocate the full 64cpus to this zone, as well as the 32/64gb of ram.

SAP runs as one thread within the zone, but the zone then allocates this thread across all the cpus.

Works like a dream,

Regards

James

Hi Brendan,

we have several SAP ECC installations with some T2k included. What we recommend from our experiences: the T2k is very slow if you focus on the peak performance compared to a x64 server. So we used the T2k as database server, connected with SAN, using mutlipathing. And from our point of view the T2k performs very well. As the AS layer we used x64 server (like X4200/V40z) and installed the databases on the T2k in zones. T2k has a lot of RAM and we configured the database with more data cache than we do usually - minimizing the storage access.

We cannot recommend using T2k as application server as the machine is quite slowly. We have a test installation on a T2k for some developer and due performance simple programming projects take a long time.

Just our experiences...
