  You cannot mix SAS and SATA in the same array. You also cannot mix HDD and SSD. If the S300 doesn't support SSD, then it may not know the difference between a SATA SSD and a SATA HDD, so it may work, but 1) I wouldn't count on it, and 2) just know that on real RAID controllers, it can't be done. In the end, I'm not sure if it will accomplish your goals. The reason I asked is because you may have been able to just add the SSD's as a new VD, then move database files, etc. to it to improve speed, but this all sounds like a lot of work for little return. I'd just invest in a good backup, recovery solution. Can this run in a virtual environment?
We have an older PE T110 first generation with a PERC S300 RAID controller and 4x250GB drives. However, because the controller is older, there is not much in terms of documentation on SSD compatibility. Has anyone had any success upgrading any server/workstation using a PERC S300 with an SSD of any kind in RAID 10 configuration? Lastly, I don't recall what kind of connector is on the existing drives and am a little confused about the difference between SATA and SAS. What normally comes stock with this system and what would I need if I moved to SSD's? New cables? Anything else I would need to know?
