Eric, We installed ARS on a T2000 in 2006 (it is still there) and never had any performance issues. However, we have home-grown apps and rarely have as many as 50 concurrent users. Oracle 10g and Mid-Tier are on the same box. CPU utilization is always low (<5%).
We do have Oracle databases running on T5220s. We were running in production for a couple of months when someone kicked off a job that caused an issue with disk utilization (the disks internal to the box). Because the write actions require 4 I/Os to the disk, it created waits which denied other users access to the Oracle apps. We opted to move the DBs to a arrays with a large amount of cache and the problem disappeared. Before we bought the T5220s, we also looked at the M3000. At the time, the pricing was similar except RAM was expensive for both machines (more, I believe, for the M3000). The T5220s have had a few issues with firmware, but we have found a stable version.

I was told by my capacity planning guy that Oracle 10G is one of the apps performing poorly on T-Series, while PeopelSoft app just fly on T-series box. We don't want to take a chance so we pick M3000. Eric On Thu, 12 Aug 2010 21:01:37 +0000, michael campbell <soup...@hotmail.com> wrote: > >I guess I should have weighed in earlier. We run full ITSM for a couple different organizations, to include SRM, KMX, and a full CMDB. We are doing this on T2000s in one organization, and T5120s in another. Oracle 10G and 11G and never had any performance issues. These things smoke. In an older implementation, I had 280Rs now 440s, full 5.5 ITSM, still purring. >mike > >> Date: Thu, 12 Aug 2010 17:31:33 -0400 >> From: ezh...@entergy.com >> Subject: Re: Sun Server T5120 >> To: arslist@ARSLIST.ORG >> >> Will do. >> >> On Wed, 11 Aug 2010 12:43:17 -0500, Axton <axton.gr...@gmail.com> wrote: >> >> >Interesting.
