Smarts on new Sun servers T5220 - T5240
The Smarts family installation guides mention Sun models which are closed to end-of-life, namely V490.
Has someone experience of Smarts installation on Sun servers such as T5xx0 (with solaris 10)?
Is it supported by EMC?

FYI...
I have been performing some quick and dirty benchmarking of the new Sun T5120 server versus an older V480 for an AM server.
Basic specs are:
V480 with 8G RAM, 4 CPU each @ 900Mhz
T5120 with 16G RAM, 1 x 1.2 GHz UltraSPARC T2 8-Core, 64 Threads
Both running latest AM 7 code on Solaris 10.

Foundation V7.0.2.0(72591), 14-Jun-2007 04:18:43 Copyright 1995-2007, EMC Corporation - SmartPack 2, Build 1
Somewhat surprising, I have found the performance virtually identical between the two servers.
Discovery: I set both servers to discover (via seed file) about 3,200 satellite terminals and the discoveries completed within a few minutes of each other.
Reconfigure Time: Both servers take about 15 minutes (+- 1 minute) to complete reconfiguration of the 3,100+ devices. CPU usage during reconfigure is very different between the two servers, but I think that goes more to how it is reported by the multi-core architecture of the 5120. Using the domain manager GUI to connect to either domain is sluggish at best while reconfiguring.
Polling statistics: Virtually identical
Conclusion:
* It looks like the combination of the number of devices + network latency are the highest determining factors in AM polling performance.
* Clock speed + number of devices determines the reconfigure time.
o The multi-cores of the new T5120 box are somewhat wasted using the same configuration. There may be some custom configuration to crank up the number of threads that could help in this area.

Thanks for your answer. It's quite helpful.
I am also looking for some sort of "EMC official" statement that says the T5xxx family has been tested for Smarts and is a recommended platform.
Any idea where to find this kind of info?
best regards

The official answer from EMC was that the T52xx series was NOT recommended for AM/PM services. Those servers are acceptable for the Adapter platform and SAM services however. As an enterprise we have decided to migrate to SMARTS on the Linux platform as you can get much more horsepower now with equal reliability and much less expense on x86 hardware.
