Overview

The HP 749800-001 is a P244br/1G FBWC RAID controller engineered specifically for HP ProLiant DL160 and DL180 Gen9 servers running v3 or v4 Intel Xeon processors. It provides hardware-based RAID functionality that offloads storage management from the main server CPUs, allowing the system to dedicate more processing power to applications and workloads. With 2 internal SAS ports operating at SAS-1200 speeds, it connects directly to the server's drive bays to manage disk arrays with minimal latency.

The 1GB flash-backed write cache is the controller's most critical feature for data integrity. Unlike traditional battery-backed caches that degrade over time and require periodic replacement, the FBWC uses flash memory to preserve cached write data during unexpected power events. This means data in transit is protected without the ongoing maintenance overhead of monitoring and replacing batteries. For organizations running these Gen9 servers in production environments, this controller provides a proven, cost-effective way to maintain RAID protection and storage performance.

Pros & Cons

👍 Pros

  • 1GB flash-backed write cache protects data during power failures without relying on a battery.
  • Hardware RAID offloads storage processing from the server CPU for better overall system performance.
  • SAS-1200 interface provides high-bandwidth connectivity to internal drive arrays.
  • Designed as a drop-in component for DL160 and DL180 Gen9 servers with no compatibility guesswork.

👎 Cons

  • Compatibility is limited to specific HP ProLiant DL160/DL180 Gen9 server models only.
  • Only 2 SAS ports, which may be insufficient for servers requiring extensive drive connectivity.
  • As a previous-generation controller, it lacks support for newer NVMe or SAS-2400 standards.
  • Requires a compatible Gen9 server chassis, so it cannot be repurposed in other hardware platforms.
