HPE SFF Flash Adapter with Dual Micro Form Factor uFF SSDs
The HPE Small Form Factor (SFF) Flash Adapter packages two 6G SATA Micro Form Factor (uFF) SATA Solid State Drives (SSDs) in a Dual Domain SFF Smart Drive bay which enables customers to install twice as many drives in an HPE Synergy compute module when compared to standard SFF Smart Drive bays.

HPE Synergy is a single infrastructure of physical and virtual pools of compute, storage, and fabric resources, and a single management interface that allows IT to instantly assemble and re-assemble resources in any configuration. As the foundation for the New Style of Business infrastructure, HPE Synergy eliminates hardware and operational complexity so IT can precisely deliver infrastructure to applications faster and with greater flexibility.

The HPE SFF Flash Adapter with Dual uFF SSDs increases flexibility, availability and serviceability for storage resources inside the compute module. The HPE SFF Flash Adapter with Dual uFF SSD option increases the composability of the compute module by enabling configurations that support a broader range of applications and workloads by providing up to 4 drives (2 x HPE SFF Dual uFF SSD options) within 2 drive bays, for example for higher drive performance, or when an on-line spare drive is needed. When higher application availability is required, customers can separate RAID1 mirror boot drives from the application. DATA availability is increased by being able to configure a RAID5 set, which also means more usable capacity

HPE SSDs deliver exceptional performance and endurance for customers with applications requiring high random IOP performance. These drives deliver higher performance, lower latency, and more power-efficient solutions when compared with traditional rotating media.
