DAQ still stable, one week on

Its been a week since the DAQ reconfiguration which reduced the NFS/QFS disk loading and both framewriters continue to be 100% stable. The attached plot shows the restarts of h1fw0 (red circles), h1fw1 (green circles) and the DAQ system as a whole (blue squares) for the month of July. The Magenta lines show when h1fw0 and h1fw1 were modified. In the past 7 days, the only restarts of the framewriters are associated with complete DAQ restarts.

Which indicates the existing aLIGO DAQ frame writer meet/exceed the original design requirement (~10MB/sec frames to disk). They do not meet the current needs of ~30-40 MB/sec, of course
