Using Solaris’ Dtrace functionality a systems engineer determines that noise is responsible for his intermittent disk latency problems. Just wait for the last part of the video, it’s worth it.
I usually don’t like to cross-post between blogs, but this problem seems prevalent enough that it needs more exposure. We’ve solved it at TLF, and here’s how:
So, I finally had a chance to play with VMware ESXi. It’s pretty much what I expected, a straight-up version of ESX. Very, very nice… I’ll start moving more servers over from VMware Server 1.x and report back on my progress.
One of the things that annoyed me out of the gate is the lack of SSH support. It’s there in the underlying operating system, just not enabled. Here’s how to turn it on:

Type “unsupported”
Enter the root password at the password prompt.
Edit /etc/inetd.conf with vi, and uncomment the SSH line
Yet another cool-geeky thing. Sort of wraps LoTR in with steampunk to bring you the wickedest clock I’ve ever seen:

Your life is being eaten away by time, second by second, and represented by the Chronophage eating away, bit by bit. Oh yea, when it strikes the hour it sounds like chains falling into a coffin.
