How to Cool a Multi-Petabyte Rack Mount NAS Storage Servers
Cooling quickly becomes the bigger issue when compressing multi-petabytes (PB) into a small RAID or JBOD NAS rack mount storage server chassis. Space compressing complicates airflow. CFM and pressure need to provide adequate LFM across the device based on the predicted or known ambient temperature of the server room’s cool aisle. Elevation also plays a role in determining adequate cooling. As the installed storage server moves from sea level to a higher elevation, the air becomes thinner and less effective at removing heat.
Removing restrictions to flow that increase back pressure becomes vital. This is combined with different methods to move heat off the device into higher LFM and lower temperature ambient. Another critical aspect is if the enclosure is negative or positive pressure.
We frequently use CRPS power supplies as they are hot-swappable, have a range of available watts, and can be upgraded on the fly if power requirements change. Rack mount NAS storage sub-assemblies may include individual storage devices, redundant hot-swap power supplies, and redundancy in hot-swap fans. The benefit is you can replace or upgrade each sub-assembly without powering down and taking your rack mount storage server offline.
Not all storage data applications require rack mount RAID storage. Production of custom rack mount JBOD NAS storage still has its place in applications. We have designed and manufactured both rack mount JBOD and RAID storage servers.
