Not to be confused with the popular storage requirements calculator, this new tool from the MS Exchange team was created to help you determine the mailbox server disk costs (purchase price and lifecycle power and cooling costs).
The calculator helps in two ways:
- The calculator takes a series of storage design configurations and determines their respective costs. The underlying goal here is two-fold:
- To show that you can achieve the same capacity and I/O requirements utilizing Small Form Factor SAS disks for relatively the same cost as Large Form Factor FC disks.
- To show that there are other disk solutions (e.g., SATA) that can be viable and reduce the disk footprint cost.
In the situation where you are unsure whether you want to deploy Single Copy Clusters (SCC) or Cluster Continuous Replication (CCR), the calculator can compare SCC+SAN disk configurations against CCR+DAS disk configurations from a cost perspective.
