Christoph, I am running both my fault tolerant SpectroSERVERs and my two One Click servers along with 10+ other servers as Logical Domains (Oracle VM 2) on two T4's with 64 gig RAM each. From a CPU performance point of view, it is really a blessing compared to my old V240 and 440 boxes. I have assigned 12 virtual CPUs and 12 GB memory to my primary SS and it is virtually doing *nothing* while running a lot more smooth than with the old hardware.
The only bottleneck is my local storage. We are running ZFS on four 600 gig HDDs with RAID10 for the LDOM storage pool. In this case, make sure you assign enough memory and CPU power to your I/O domain or you will encounter huge performance problems with your drives. In my case, a whole CPU core and 8 to 12 GB memory seemed to do the job. One problem though I do still have: My ArchMgr keeps dying when I do huge SQL accesses directly to the MySQL database. This didn't happen when I was on V440, but there is no explanation whatsoever why this should only appear on my new hardware; CA is still investigating.

One of my customers has to renew his hardware. At the moment he uses the M3000 servers from oracle, which is the official recommendation from CA. My support request for the new T4 series was answered with ?CA doesn?t have any experience on this hardware and so the recommendation is still the M-series?. I also asked a Oracle technician, who told me that the T4 series is a lot of better in single-threading than the old T2 series and should be a good choice for Spectrum. Anybody here has some experience with the T4 series and Spectrum?
