SAN Performance on a Internal Disk Budget: The Coming Solid State Disk Revolution

Present finding gathered over 6 months working with solid state technology. The current generation of solid state drives can perform 5K random reads per second, while the current 10K rpm disk drive performs about 200 random reads per second. Thats a 25X performance improvement for 2-3x the cost of a single 10K drive.

Outline from my presentation:

- Solid State Disk!

-
  When was the last Jump in disk technology? 
  When was the last big break through in memory?
  When was the last big break through in CPU?
  When was the last big break through in disk?

-When? -Memory: DDR : 2000 DDR2 : 2003 DDR3 : 2008 -CPU : 2000 P4 2002/3 hyperthreading 2005 64 bit! 2006 Dual Core – 2007 Quad Core -Disk? VH1’s back to the 90’s NO MAJOR CHANGES SINCE BILL Clinton WAS IN OFFICE! 10K RPM 1996 15K RPM 2000 8 years since something good, SSD is game changing

- Why?

- Sun Loves Solid State

- What is SSD?

- Why is it so cool?

-Disk is the slowest part of a system Harddrive access times < 5ms Memory access times < 60 ns Cpu cache access times < 10ns SSD < .5ms

The majority of workloads tend to have some sort of IO issues
Lower failure rates

- What will this due to disk? Revolutionize disk

-Different SSD type technologies: Flash Based SLC vs MLC DDR Based MTRON & Memoright disks!
