How Western Digital Data Center Enclosures Work

Designed for Extreme Density and Flexibility

The Ultrastar Data60 and Data102 hybrid storage platform are a key element of next-generation disaggregated storage and Software-Defined Storage (SDS) systems. The extremely dense form factor provides the flexibility to specify the HDD and SSD combinations for balancing capacity, performance, and cost.

A flash data acceleration tier can be enabled to serve both fast data and big data applications from a single platform. The Ultrastar Data60 and Data102 address the demanding storage needs of large enterprise customers, storage OEMs, cloud service providers, and resellers/integrators that require dense, shared HDD or hybrid storage.

How IsoVibe Works

IsoVibe is a collection of Western Digital patented design innovations. Precise cuts in the baseboard act as a suspension for the drives providing isolation from the vibration transmitted from one drive to another. Vibration-isolated fans also minimize vibration and noise transmission. Additionally, vibration-isolated fans reduce the amount of transmitted interference and acoustic vibration.

Comparison testing in standard environmental conditions against two conventional enclosures showed that IsoVibe reduces rotational vibration of the drives by over 60%. Also, testing against another competitor enclosure showed head positioning total run out (a key measure of how a read/write head stays on track) reduced by 24%.
This management of vibration ensures that the drive heads are less likely to be thrown off track and therefore more likely to maintain desired performance.

The overall benefit is that performance is maintained across the platform, even when all the drives are working hard. Shock and vibration control is a significant factor in our disk drives and also our enclosure products. IsoVibe will allow Western Digital to introduce future products with even tighter track densities and enable them to operate in dense enclosures with minimal performance degradation


How ArcticFlow Works

The enclosure is divided into two zones, with rows of drives in the front, and rows of drives in the back. The front zone is cooled conventionally with the air drawn in from the cold aisle, but the warmed air is then ducted around the sides of the rear zone directly to the hot aisle. For the rear zone, cold air is drawn straight from the cold aisle into the center of the box and distributed through the rear drives, and to the exhaust on the hot aisle. This patented Western Digital technology brings innovation to a well-established product segment and delivers significant benefits.

In testing against a competitive enclosure, the Ultrastar® Data102 requires just over half the cooling power per drive slot. To put this in perspective, using California energy costs and typical data center efficiency, the savings amount to $1,500 per enclosure over a typical five-year system lifecycle. In a large data center with 20,000 drives, this could be as much as $300,000 savings in energy costs.

In testing the Ultrastar Data102 against the competitive enclosure, 30% of the drives in the competitive boxes ran at an average of 13┬░C hotter than in the Ultrastar Data102. Using an Arrhenius model for reliability de-rating, those drivesrunning at elevated temperatures are 44% more likely to fail. Thus, based on this model the comparable enclosure without ArcticFlow is likely to have 13% more drive failures over its life.
