It would seem you're one of the countless we see here with hardware, real or imaginary, who has no workload, or is seeking a workload for his hardware. This is the wrong approach. You need to approach this list with: 1. This is my workload 2. This is the hardware I currently have (suitable or not) 3. How do I best setup my storage to meet my workload requirements? You're approaching this backwards. -- Stan
