HPE QTH8654-CU-HP 4-Port 25GbE Host Bus Adapter
Overview
The HPE QTH8654-CU-HP is a high-speed, quad-port Host Bus Adapter (HBA) designed to provide robust and scalable connectivity for modern enterprise storage arrays. Officially designated as the HPE N9Z37A 10/25GbE 4-port Host Bus Adapter, it is engineered specifically for integration with HPE Primera and HPE 3PAR storage systems. This HBA addresses the critical need for high-bandwidth, low-latency I/O to eliminate storage bottlenecks in virtualized and flash-based data center environments. At its core, this adapter leverages QLogic technology to deliver reliable performance across four flexible ports. Each port can be configured for either 10GbE or 25GbE speeds, allowing IT managers to seamlessly migrate from existing 10Gb infrastructure to a higher-performance 25GbE network fabric without a complete hardware overhaul. This flexibility maximizes return on investment and provides a clear path for future storage network upgrades. Designed for demanding workloads, the QTH8654-CU-HP is a full-height PCIe 4.0 card that installs directly into a controller node of the storage array. Its primary role is to aggregate multiple host connections, providing the essential link between servers and the storage backend. Management is integrated within the HPE storage platform's native toolset, simplifying configuration and ongoing maintenance for administrators.
