Product Description
The HPE 451344-B21 SAS 3Gb Pass-through Module is an essential component for expanding storage capabilities within HPE ProLiant server environments. This module is engineered to provide a direct, unmanaged connection between the server's SAS host bus adapter (HBA) and external SAS storage devices. Unlike managed switches or controllers, the pass-through module simply routes the SAS signals, offering a straightforward and cost-effective solution for increasing storage density. With sixteen SAS ports, this module offers significant connectivity for direct-attached storage (DAS) configurations. Each port operates at the SAS 3Gb/s standard, ensuring adequate bandwidth for many storage applications. The pass-through nature means that the server's operating system or HBA directly manages the connected drives, simplifying the storage architecture and reducing potential points of failure associated with active management components. This module is particularly useful in scenarios where simplicity, reliability, and direct control over storage are paramount. It is ideal for configurations requiring the connection of multiple hard drives or solid-state drives directly to the server, such as in storage servers, high-performance computing nodes, or environments where external JBOD enclosures are utilized. The 451344-B21 ensures robust physical connectivity for SAS storage expansion.
