HP 488454-001 16x Ports SAS 3Gb/s Pass Through Module

Product Description

The HP 488454-001 is a specialized SAS (Serial Attached SCSI) module engineered to provide direct, unmanaged connectivity for storage devices within compatible HP server environments. Featuring 16 individual SAS ports, this module acts as a simple conduit, passing data signals directly between the server's SAS controller and connected hard drives or storage expanders. This pass-through architecture means the module itself does not perform any RAID (Redundant Array of Independent Disks) operations, leaving all storage management and configuration to the host server's controller or operating system. Operating at a SAS interface speed of 3Gb/s, the 488454-001 module ensures adequate bandwidth for a variety of SAS drives, including HDDs and SSDs, as well as for connecting to external SAS expanders to further increase drive counts. Its primary purpose is to facilitate direct-attached storage configurations, offering a straightforward and efficient way to integrate internal or external SAS storage without the overhead or complexity of hardware RAID controllers. This makes it ideal for applications where software RAID or direct drive access is preferred. This module is typically found in HP ProLiant server configurations that require extensive direct storage connectivity. Its design prioritizes simplicity and performance for direct storage access, making it a crucial component for storage-intensive workloads, high-performance computing, or environments utilizing software-defined storage solutions. The 16-port density allows for significant storage expansion within a compact footprint.
