Hi Andrew, thanks for your input. So what we know by now: No matter which Solaris version we run, the effect always seems to be the same. What I forgot to mention in my previous mail: The T2000 is equally as noisy! I had one for a short period of time in 2010, before I needed to sell it again. When I first switched on the T2000 I didn't believe my ears. And just as with the T1000 this noise wouldn't decrease through picld at all :( It is as if Porsche designes a top-end sports car, and everything is just amazing. Only a tiny problem: Due to a minor design flaw you cannot close the windows at all. Ok, so to me the only solution seems to be: A) Run it remotely, never be in the same room. B) Replace the fans, or take the system itself into another chassis all together. %martin ------------------------------------------- illumos-discuss Archives: https://www.listbox.com/member/archive/182180/=now RSS Feed: https://www.listbox.com/member/archive/rss/182180/21175430-2e6923be Modify Your Subscription: https://www.listbox.com/member/?member_id=21175430&id_secret=21175430-6a77cda4 Powered by Listbox: http://www.listbox.com
