+- Swap solid-state drives in place of spinning hard disks
+- Install faster CPUs
+- Lower SLA expectation at a cheaper maintenance cost

+- Replacing hard disks with solid store drives
+- Swapping the CPU for a faster model
 
+Horizontal:
+- Purchasing 4 more systems for a total of 13 processing systems
+- Adding more CPUs to add more processing lines
