Abstract
A storage system enclosure can hold hundreds of hard disk drives (HDDs) and uses high speed cooling fans to control the HDDs’ temperature. The noise and vibration induced by cooling fans will impact HDD performance – IOPS (Input/Output operations Per Second). Currently, foam is added between the HDD’s printed circuit board assembly (PCBA) and basedeck to minimize the impact on HDDs performance. However, the existing foam is smaller, which limits the effectiveness. In this paper, it is proposed to extend the foam to the interface connector area, 1) increasing the effective foam area; 2) adding a constraint to the interface connector to limit PCBA vibration and impact on basedeck. The prototype of the proposed HDD design was built and tested. IOPS increases by 14.6% for sequential write and IOPS increases by 9.2% for random write at the challenging high fan speed.
