HPE 804228-B21 Smart Array 12GB PCI-Express 3 X8 SAS Expander

Product Description

The HPE 804228-B21 Smart Array SAS Expander is a crucial component for expanding storage capacity within HPE ProLiant servers. It connects to an existing HPE Smart Array Controller via the PCIe interface and provides additional SAS ports, allowing for a greater number of SAS and SATA hard drives or SSDs to be integrated into the server's storage subsystem. This is particularly beneficial for configurations requiring a high density of drives or for future scalability. Operating at 12Gb/s SAS speeds, this expander ensures that the increased number of drives can still achieve high-performance data transfer rates, maintaining the overall efficiency of the storage array. The PCI-Express 3.0 x8 interface provides ample bandwidth for the expander to communicate effectively with the host system and the connected drives, preventing bottlenecks. It is designed to work seamlessly with compatible HPE Smart Array controllers, ensuring a robust and reliable storage solution. By utilizing the 804228-B21, IT administrators can build more extensive and flexible storage solutions without needing to replace their existing Smart Array Controller with a model that has more native ports. This cost-effective approach allows for the addition of more drives for increased capacity, improved RAID configurations, or enhanced data redundancy, supporting the evolving needs of data-intensive environments.
