Hello,

thank you for your ideas.

A few additional questions: For better IO/s performance we think about using more drives with 1GB (or less). So we get 11TB in a RAID5. This gives us 8x11=88TB for a single server machine which is near our capacity targets -- great. Backup will be done with a second identical server+storage system.

Now the next question: Given this machine with 88TB, how can we further scale capacity and performance when this system is not enough. This will be 3 years from now.
