hp smart array controller is in a lock-up state

It really seems like a storage issue, every error leads to that, however everything storage related has been tested or replaced (except for cables, backplane, harddrives themselves). HPE want us to replace the controller again. VMware suggested a few things that did not solve the issue, now states that the problem is within the hardware. We have opened cases with both VMware and HPE.

Reinstalled ESXi completely using configuration backup.

Updated smartpqi driver from VMW to OEM version

Limit IOPS for VM to 400, resulted in smartpqi timeout PSOD.

Updated ESXi 7.0 to 7.0U2 (both installations using HPE image).

Updated all server firmware using newest HPE SPP.

has entered the All paths down stateġ719-Slot 0 Drive Array - A controller failure event occurred prior to this power-up, lock up code 0x27006 Should this be the expected behaviour, shouldn't storage just start to throttle? And vice-versa, storage can handle the Veeam jobs, but when moving operations start storage again times out.

When moving operations happen storage behaves just fine, however the server also hosts a Veeam VM for backups, when the backup occurs the storage just crashes. In short - We have VM with multiple large disks (10s of TBs), we need to move data between them.

Hello, we currently have an unpleasant case where upon storage activity the datastores timeout, host alongside with VMs has to be reboot in order to regain access.
