759559-001 HPE Smart Array 2GB FBWC 12GB SAS Controller

The HPE 759559-001 Smart Array Controller is a RAID (Redundant Array of Independent Disks) controller, which means it provides redundancy and fault tolerance to a storage system by combining multiple physical disks into a single logical unit. The controller is designed to support up to 12Gb/s SAS (Serial Attached SCSI) interface and offers compatibility with HPE’s ProLiant Gen9 and Gen10 servers.

One of the key features of the Smart Array Controller is its 2GB Flash-Backed Write Cache (FBWC). The FBWC is a high-speed memory buffer that can temporarily store data being written to the disk. This allows the controller to write data faster and more efficiently, as it can bundle multiple writes into a single larger write.
