Finally got some breathing space for my first post of the year! In order to get a major client through Christmas which is traditionally their busiest period of the year (where load normally goes up five-fold), we embarked on a major platform refresh where both the back end SQL Server DBMS was upgraded from SQL 2008R2 to SQL Server 2012 and the hardware was upgraded to 2 x Dell PowerEdge R910s with 4 x 10 (physical) cores and 512GB of RAM in each server.
Do you have tempdb on Fusion-io (or equivalent) technology? Is your reindexing job left on default settings (re-orgs at 5-15% and full rebuilds at @ 30%)? If so, then you might be interested in the findings in this post. The benefits of flash memory as a replacement for spinning drives in order to boost SQL Server performance is well documented. However, I’m not sure if one particular benefit has been fully exploited.
