Hello.

 

We are currently experiencing performance issue on our setup that is using iSCSI on HUS 130

 

Is it possible to change flowcontrol option?   Strangely, the Hitachi engineer who helped our setup was not aware if flowcontrol

 

is being supported on this platform but from my packet capture (Portspan), we have figured out that this device was sending

 

huge number of pause frames to its connected switches. I wonder if there is no way to turn this off as i now suspect this is the

 

culprit of this performance issue. 

 

 

One other thing is how to check if HUS is configured for SCSI3 - reservation.  The host OS is windows 2012 Hyper-V and the performance

 

is getting worse when turn on several VMs so i like to make sure that SCSI3 is configured and working properly.

 

If  anyone has any idea please shed some light on this..

 

Thanks.
