## Summary description

The HPE SmartArray P441 is a 12Gb external SAS RAID controller with 4GB FBWC. It supports RAID levels 0, 1, 5, 6, 10, 50, and 60, ensuring data protection and performance. With a data transfer rate of 12 Gbit/s and 4096 MB internal memory, it is designed for high-speed data processing. The controller is compatible with SAS and SATA drives and features a PCI Express x8 interface. Dimensions: 241.3 mm x 57.2 mm x 90.5 mm. Ideal for enterprise storage solutions.

## Long description

The HPE Smart Array P441 Controller is a low-profile PCIe3 x8, 12 Gb/s Serial Attached SCSI (SAS) RAID controller designed to add external storage capacity and enterprise-class storage features to compatible HPE ProLiant Gen9 rack and tower servers. The controller provides eight external physical links, support for transportable flash-backed write cache (FBWC), and advanced RAID capabilities to maintain data availability and simplify storage expansion for servers with limited internal space.
Advantages
The controller increases storage performance by offering 12 Gb/s SAS connectivity and an optional 4 GB DDR3-1866 flash-backed write cache that reduces write latency in logging-intensive workloads. It supports transportable FBWC for cache migration to a replacement controller, optional HPE Secure Encryption to protect data at rest, and predictive spare activation to improve rebuilds and uptime. Integration with HPE Smart Storage Administrator and compatibility across the Smart Array family simplify configuration and future migration.
Key specifications
Interface: PCIe3 x8
SAS speed: 12 Gb/s Serial Attached SCSI (external)
External links: 8 physical links
Cache: Transportable 4 GB DDR3-1866 Flash-Backed Write Cache (FBWC)
Optional features: HPE SmartCache, HPE Secure Encryption
Supported servers: Select HPE ProLiant Gen9 rack and tower models
How to use
Install the HPE Smart Array P441 Controller into an available PCIe3 x8 slot in a supported ProLiant Gen9 server and connect the external SAS storage devices to the controller’s external ports. Use the included HPE Smart Storage Administrator (available via intelligent provisioning) to configure RAID arrays, enable FBWC and optional features such as SmartCache or Secure Encryption, and perform ongoing management. If replacing the controller, transportable FBWC allows cached data to be migrated to the new controller to preserve write data.
Recommendations
For improved write performance and data reliability in database or logging-heavy workloads, enable the transportable FBWC and consider adding HPE SmartCache. Use HPE Secure Encryption where regulatory or security requirements mandate data-at-rest protection, and manage arrays via HPE Smart Storage Administrator for straightforward configuration and migration within the Smart Array family.
