HPE 874576-B21 ML350 Gen10 12Gb SAS Expander Card
Overview
The HPE 874576-B21 is a storage controller upgrade card designed to dramatically scale the internal storage capacity of specific HPE ProLiant servers. It directly addresses the need for greater drive density within a single server chassis, making it a critical component for businesses experiencing rapid data growth, particularly within the HPE ProLiant ML350 Gen10 tower server environment. This kit provides a straightforward path to adding a significant number of internal drives without the cost of an external storage array. At its core, the card functions as a high-speed data traffic hub for your storage subsystem. Leveraging a 12Gb/s SAS interface and a PCI Express 3.0 host connection, it ensures that data throughput is not a bottleneck, even when the server is populated with high-performance SSDs. The expander intelligently manages connections for up to 28 internal drives, allowing for a mix of both SAS and SATA drive types to balance cost and performance. This flexibility is crucial for creating tiered storage configurations within the server itself. Designed for seamless integration, the expander card installs into a full-height PCIe slot inside the server. As a complete kit, it includes the necessary Mini-SAS cables to connect the card between a primary Smart Array controller or HBA and the server's drive backplanes. This approach simplifies deployment, providing system administrators with a reliable, manufacturer-approved solution for maximizing the storage potential of their server investment.
