Suitable for enterprises seeking faster transaction response and improved storage efficiency with minimal configuration effort.

## Long description

Flash-Based Write Cache module HP Enterprise 660091-001-RFB 1.6TB is a removable flash cache device engineered to accelerate write operations in compatible HPE storage controllers and arrays. The 1.6TB flash capacity temporarily stores incoming write data to reduce latency and improve overall I/O throughput for transactional and mixed workloads. The module is compatible with supported Hewlett Packard Enterprise controller platforms and integrates with existing storage firmware to provide fast, persistent caching without major configuration changes.
Advantages
The flash-based write cache improves write performance by buffering incoming writes on non-volatile flash, which reduces write latency and offloads immediate commit requirements from back-end disks. Its 1.6TB capacity offers a balance between cache hit rate and cost for enterprise environments. As a removable and vendor-specific module (HPE 660091-001-RFB), it is designed for straightforward installation and compatibility with supported HPE storage controllers and arrays. The solution requires minimal management while delivering measurable reductions in I/O wait times for write-heavy workloads.
Suitable for
Database systems with frequent small synchronous writes (OLTP)
Virtualized server environments and virtual desktop infrastructure (VDI)
High-performance mail, messaging, and collaboration platforms
Mixed read/write enterprise applications requiring reduced latency
Storage arrays where improved transaction response and cache persistence are needed

Form factor: Removable cache module for compatible HPE controllers/arrays
How to use
Install the HP Enterprise 660091-001-RFB module into a supported HPE storage controller slot according to the controller’s hardware installation guide. After physical installation, confirm firmware compatibility and enable write cache functionality through the storage controller management interface or HPE management tools. Monitor cache health and utilization via the controller’s monitoring utilities; the cache operates transparently to hosts and accelerates write operations once enabled. Follow any controller-specific steps for cache persistence and battery or capacitor-backed protection if applicable.
Usage recommendations
Use this 1.6TB flash write cache in systems documented as compatible by HPE to ensure firmware and hardware support. Keep controller firmware up to date and verify that any required cache protection mechanisms (such as persistent memory features or backup power modules) are present per the controller’s specifications. Monitor cache hit rates and latency metrics after installation to validate performance gains and adjust caching policies if the controller provides such controls.
