Solid State Storage TCO Calculator

This tutorial will demonstrate the Enterprise TCO calculator, the result of the SNIA SSS TCO work group. Representatives from rotating disk, DRAM, and NAND storage joined together to create an application based calculator that will return the TCO benefits, performance gains, and green power benefits of different SSS solutions. Using inputs ranging from I/O characteristics to HDD specs and capacity, the calculator churns through possible RAID configurations, replacement rates, power/performance tradeoffs, and other computations to provide the optimal SSS setup. We will walk through a few of the calculations and many assumptions we make and demonstrate the adaptability of the calculator. The results include Power, Space, and storage savings, as well as expected total IOPS, and percentage reduction in power (green drive improvement).

Learning Objectives:

• Introduce the TCO calculator, the default assumptions, and how every user can benefit from the tool.
• Explore which application scenarios return the greatest TCO opportunities, and which may not be good for a SSS solution
• Educate datacenter users and providers of the overall $$$ impact of SSS storage, beyond what is seen in the upfront cost.
