Informix on RHEL on VMWare - cooked vs. raw devices recommendation

Slow running backup
variety of reasons. a very simple test will be to take a level 0 archive to /dev/null. If the time is still slow then its probably due to either a lot of database activity or i/o transfer rate back from the storage where the db chunks reside. If fast then it's the transfer rat…

Re: HP AutoRAID question....
Billy, The main thing have noted on HP performance is that KAIO is slower than AIO VPs. But AIO VPs use a lot more CPU resources than KAIO. For example an archive on KAIO shows very little CPU usage, about 10% of 5 CPUS whereas using the AIO VPs uses 50% of three CPUs plus 5 - 1…
