OCPSummit19 - EW: Storage - HDD IOPS The Never Ending Story

Описание: In the never-ending search for higher density, hard disk drives have continued to create a widening performance gap in IOPS-TB. Over time software has evolved to compensate for this by optimizing hot and cool data distribution, as well as multiple layers of caching. With SSDs continuing to reduce in price, how can HDDs improve and be effectively used to bridge the performance gap? Multi-Actuator drives are on their way, and their introduction will require us to consider the impact to our storage platforms and the TCO models to see if they make sense. With higher performance comes higher power and thermal challenges. Presented by Jason Adrian
