This course aims to explore the operational characteristics of SSDs in enterprise storage systems through a large-scale field study. The learning outcomes include understanding the level of write amplification, effectiveness of wear leveling, and the impact of factors on SSD performance and lifespan. The course teaches about NAND usage rates, write amplification factors, and the differences between enterprise storage systems and data centers. The teaching method involves presenting findings from a comprehensive field study. This course is intended for professionals working with enterprise storage systems or anyone interested in the operational aspects of SSDs in production environments.
Operational Characteristics of SSDs in Enterprise Storage Systems - A Large-Scale Field Study
Overview
Syllabus
Computer Science UNIVERSITY OF TORONTO
Research Questions • Performance and lifespan of SSDs are affected by operational characteristics.
Systems Description . We focus on NetApp's enterprise storage systems
What are NAND Usage Rates in the field?
Write Amplification Factors (WAF) SSDs internally perform housekeeping tasks (garbage collection, wear levelling, etc.) resulting in Write Amplification
Write Amplification Factors (WAF) in production?
Which factors impact WAF? . Several factors can affect an SSD's write amplification.
