HighPoint Rocket 750 Design
The PCIe 2.0 x8 Rocket 750 features 10 SFF-8087 connectors that connect four drives apiece. There is an audible alarm buzzer at the top of the PCB, and the large heavy copper heat sink cools the HBA controller.
We spot four Marvell 88SM9715 6Gb/s port multipliers behind the four ports lining the edge of the controller. There are also four more Marvell port multipliers on the rear of the HBA. Each of these controllers supports one SATA 6Gb/s host port and five SATA 6Gb/s device ports. These chips feature integrated enclosure management features, including temperature sensors, PWM, tachometers, and voltage rail monitoring. The combination of these port multipliers with the SFF-8087 ports provides up to 40 connected 6Gb/s SATA devices. The Marvell silicon also supports SAS connections, but HighPoint does not support SAS devices with the Rocket 750.
The Xilinx XC9536XL is a 3.3V CLPD for high-performance, low-voltage applications. The real star is the Marvell 88SE9485 host controller. This controller provides an interconnect between the 5 GT/s PCIe 2.0 PHY cores, via a x8 connection, and the eight Marvell port multipliers. This controller offers RAID offload capabilities, but this functionality is not required for the HBA architecture of the Rocket 750.
HighPoint Rocket 750 Specifications
The HighPoint Technologies Rocket 750 provides users an easy-to-use Intelligent Storage Health Manager that provides simplistic control and monitoring functions for the HBA and controlled devices. SMTP provides email alerts for system events, and the physical device pane allows adjustment of drive read ahead, write caching, and NCQ settings. There is also the much-appreciated Identify LED function for locating a pesky drive among the stack of 40 attached devices.
