Hello,

We are using IBM Director 4.20 with our servers.
Windows 2000 US SP4 or Windows 2003.

On these machines if I look the counter "System/File Data Operation/sec", I see consistently high usage.
Without IBM Director : 20 to 40
With IBM Director : 2500 to 3000 on average

The processes generating this load are :
RaidServ.exe : ServRaid Service
PegasusProvider.exe : ??
TWGIPCSV.exe : IBM Director Support Program

Is this normal??

In fact I dont see a real impact in term of performance, but in an MSCS cluster it generates communication errors (events 1122/1123) between the two nodes...

I tried with 4.22, same problem.

Thx in advance for your answers
