We may need more servers in the future. This task is to estimate the hardware requirements so those figures can be passed on to Tech Ops.
CPU: Dual Intel(R) Xeon(R) CPU E5-2640 v3
Disk: 800GB raw raided space (2x 800GB SSD RAID1 or similar, software RAID is fine)
Number of servers:
eqiad: 36-31 = 5
codfw: 36-24 = 12
numbers are: [desired size of cluster] - [current size of cluster] = [number of servers to add]
