One of my T620's with H710P adapters has crashed 3 consecutive weekends in a row when it was receiving lots of data (dozens of VHD files) to be written. The system is Raid-5 with 5 SAS 600GB disks.
I am pretty sure all drivers are up to date. The system runs fine when under normal loads but has crashed under heavy loads 3 times now which is of obvious concern. Any suggestions other than contact Dell support and requesting a new adapter?
