With "4-port SAS Cable Port" you mean a break out cable and you have not a 4 port Card? I ask because the "Dell 12Gbps SAS HBA" should be the standard dual port HBA and normaly you need a standard one-to-one cable to connect your devices to that HBA.
Iam not aware of a #PN for a 4 Port Cable.  I have seen such a cable in an HPE environment.

You see a error within Dell Storage Manger (for Compellent) or within the Windows OS? Do you have connected a Compellent SAN and your Tape to your Poweredge Server?

Note: In the past, with the old 6Gbit SAS HBA as soon as you have a Tape/Library connected no other devcies where supportet/allowed.  Not sure about the new 12G four port HBA.

You may post in the wrong forum section. If possible send a screenshot.

Hello 3 Zinc

Could you please suggest driver for for my Dell R740 Server Windows 2019 ,  I was looking for it but couldn't find. what type of driver RAID or NON-RAID ???

You should describe or send a foto of your SAS HBA.  The already installed Dual Port 12G SAS HBA is the right one for a 14Gen. Server.

If you have installed  OMSA or a iDRAC Enterprise you can take a look into the HW Inventory to identify the Card,

@Origin3k  

Yeah I checked in IDRAC there are two adapters

Dell HBA355e Adp is 4-Port for Tape-Library

Dell 12Gbps HBA is 2-Port  for Backup server 

& I also Searched for the driver of Dell HBA355e only

"SAS-Non-RAID_Driver_YCHJ6_WN_2.61.29.02_A02.EXE"  is coming , so that is compatible with my system ??  Do this NON-RAID Driver break RAID Configuration ??
