Hello slekutis,   Unfortunately this would not be a suitable platform for your recovery. Neither the T620 itself or the H310 are validated for Server 2019.   The T620 supports up to Windows Server 2016 : [URL] The H310 should have native support in WS2016.  We don’t have a Server 2019 driver for the H310.   See if you can find something more like the original host.   Please let me know if you have any other questions.
We have a T620 server with a PERC H310 RAID adapter. We're trying to recover an image from a different server that runs Server 2019 to this one. The recovery runs about 6 hours and then fails with a variety of error codes.  Is the PERC H310 adapter compatible with Server 2019?
