I am running the latest version of the Beta firmware with ATTO ISCSI initiator.
Pro 6 connected to a MacPro 10.7.3 via a Netgear Gigabit switch.
Yesterday I noticed something odd, and for the first time I encountered performance issues with the ReadyNas.
I was running two Windows Server 2008 VM's over ISCSI and then tried to copy a 12GB file onto the NAS over an AFP share. What happened was that the file copied 256MB across and then the write performance on the NAS just disappeared. The VMs were so incredibly slow that they became unusable, and the file copy operation went from 4 minutes to 72 hours.
I was able to get onto Frontview on Firefox, but even this was painfully slow. CPU was around 82% idle so I don't know what was causing the slow responsiveness. I turned off Jumbo frames but that made no difference.
I can reproduce this every time.
Is there any tests I could run or you could run internally?
