Each server has 1 GB RAM so have rerun with '-s 2047' in each case.
Yeah I could have patched it to use multiple volumes these are live
servers and I didn't want to put that much of a load on them.
) ) Looking at the specs for ExtremeRAID's: the base 1100's have
) ) StrongARM's @ 233MHz!!! wow.... anyone have one of these to run a
) ) bonnie on? (Dave Rynne)
)
) Yup, I can oblige. Here's a bunch of bonnies off three different servers
) with 1100's & MegaRAIDs. Each box was fully up at the time. Have included
) details of the drives in each case and the relevant chunk from dmesg.
