[linux-lvm] LVM on SATA/PATA disks

["Bertrand Renuart" <bertrand renuart modulo1 be>]

Dear all,

I always have been told (S/P)ATA disks should somehow be avoided in server
systems. This mainly because the high rate of interrupt requests generated
by the IO subsystem will constantly interrupt the CPU which then becomes
unavailable for other server tasks. SCSI disks should be preferred mainly
for that reason.

Can someone confirm this statement?

FYI, we have to upgrade one of our development machine - hence the question.
This machine is mainly used to run unattended software builds -> moves large
quantity of small files and requires lots of CPU.

(sorry if my question is "stupid" or has already been asked many times - but
couldn't find any hint anywere)

Thanks
