What is the optimal stripe size formatting for a drive supporting a SQL 2014 DB, on Windows 2012 R2? Is it 4K or 64K?
All SQL databases are on Fusion iO cards, and our primary database is approximately 3 TB, used for both OLAP and OLTP.
Using Fusion iO cards, through Storage Spaces, we have ran iOMeter testing as follows:
· With 64k 100% read, 0% write = using 64k formatting 8,200 i/o per sec, using 4k formatting 262,000 i/o per sec.
· With 64k 50% read, 50% write = using 64k formatting 7,000 i/o per sec, using 4k formatting 11,000 i/o per sec.
