The IOMMU limit set by the hypervisor varies depending on the machine,

Yes, I came across your previous post further down the intertwined

to have monitored _all_ of the system's "health" monitors such as voltage,

How did they look for predictive models on the SMART data? It sounds
like they did a fairly linear data decomposition, looking for first
order correlations. Did they try to e.g. build a neural network on it,
or use fully multivariate methods (ordinary stats can handle it up to
5-10 variables).

Dear Mark and the List,
The head node is about a terabyte of raid10, with home directories and
application directories NFS mounted to the cluster. I am still tuning
