Dell-IMSourcing DS UN939 SAS Controller

This Dell-IMSourcing DS UN939 SAS PCI-Express controller card connects storage drives to compatible Dell PowerEdge and PowerVault servers. It installs in a PCI Express plug-in slot and presents a SAS interface for the attached drives. The card is supplied new and serves as a dedicated host adapter for SAS storage expansion.

For servers needing a SAS host adapter

System administrators adding SAS hard drives or tape units to a supported Dell server use this card to provide the required host interface. Builders working with non-Dell platforms or requiring a different host bus type should select a controller that matches their specific hardware.

PCI Express host interface

The card communicates with the server motherboard through a PCI Express host interface. Compatibility depends on the server model accepting this form factor and interface, so verify the target system supports a PCI Express SAS controller before purchase.

Does the UN939 SAS controller card include cables or brackets, or must they be purchased separately?

The card is supplied as a plug-in card only; SAS cables and mounting brackets are not included and must be sourced separately.

The PCIe host interface lets the UN939 present SAS drives to the operating system at the bus speed supported by the server's slot, enabling direct attachment of compatible SAS storage.
