From the moment when the UPS rapports "Low Battery" to the end of the shutdown, too mutch time is passing. So the computer does not have enough time shut down properly. Can I shut down the computer on the "On Batery" status? Or can I shut down when the UPS rapports 50% of the battery? Thank you.

Hi! I would like to know the status of the frequency scaling in XEN. I found a web site saying that XEN doesn’t work with frequency scaling, at the other hand I found some fixes for powernow-k8 to get rid of some messages. I have an AMD64. powerno-k8 works find with non-XEN kernels, but with XEN-kernels I get the error: powernow-k8: Found 1 AMD Athlon(tm) 64 Processor 3400+ processors

The rest were all 10, 9, or 8 oz.

..., but there are also weak cells, not clearly related to missing lead. What really matters, IMHO, is how many Ah one can pull out of the battery, and measuring that directly seems more direct. There's also the question of discharge rate. I used to use standard rates of 1 A, larger for bigger bateries, smaller for little ones. This is contrary to industry norm which is a 20h rate. Then I had batteries I wanted to return, and realized I really needed to test at the specified rate. So now i do 20h rate, which which means nameplate capacity / 20h, so 450 mA for a battery specified at 9 Ah. Wit...

In our development lab, I am installing 4 new servers, that I want to use for hosting KVM. each server will have its own direct attached raid. I'd love to be able to 'pool' this storage, but over gigE, I probably shouldn't even try. most of the VM's will be running CentOS 5 and 6, some of the VM's will be postgresql database dev/test servers, others will be
