When you Scale Out how to Scale In by Increasing Density using Raided SSD
Sharding-splitting data for a single database server onto many database servers is a method to scale horizontally and is needed to get more disk IOPS from a mechanical harddrive server architecture. Its a method that works yet has pitfalls which this session talks about. The main focus is what happens when Solid State Disk Drives replaces traditional mechanical harddrives (spinning metal) in a sharded environment and answers to questions like
How much more IOPS with SSD
What Raid Levels and Controllers work for certain SSD drives
How do you migrate data from shards to increase density on SSD Shards
Why Multi Mysql Instances per SSD server is great.
How INNODB compression really helps in an SSD environment
