[AusNOG] Global switch Level 4 Hard disk's

[Matt Perkins]

I can also confirm that the customers with cheaper hard SATA hard disks 
seem to be seeing many more problems then the people with SAS. It's also 
interesting that all the Supermicro Servers seem to be ok where the 
effected servers were all Dell's Not sure I have enough servers to make 
any case based on that But perhaps the layout of the drives of the 
Supermicro's transfers less noise then the layout of the Dell's

All in all this does appear to be a Noise related issue as a result of 
the alarm's and gas release.
