Only a little over a week before the User conference and I am still burning the midnight oil to get as much information for my presentations as possible. I thought I would tease you a bit here. What do you get when you put 4 Intel X-25E’s ( Sun branded) SSD’s running RAID10 in a Sun 4450 and run the sysbench fileio test on it?
NO CTL, NO DRIVE

*NO CTL or W CTL : No controller cache, or with controller cache
*NO DRIVE or W DRIVE : No onboard drive cache, or with drive cache
What does this mean? What about RAID 5 Numbers? What about actual MySQL Results? Come and see me talk about it in a week! Or wait for the post UC cliff notes if you can not attend. You know this is just a teaser:) Get this and more if you come and listen to me drone on and on about SSD’s! I will say this… A client I work with has a 16 disk raid 10 array ( 10K disks ) with 2GB of cache that scores around 2500 Requests per second in all of the above tests… just giving you some food for thought.
** Server has a Adaptec RAID Card with 256MB of battery backed cache. OS was Redhat 5.3, ext3 … 64K Stripe size
