We decided to apply the cost model here because the internal infrastructure details and pricing for well-known data centers are not publicly available. However, the full cost accounting model for storage is applicable for any kind of data center and cloud storage systems. 1 Initial Cost The CIS data center was developed in 2011. There are total 4 server racks and each rack contains 9 units. Each unit has the following configuration: 1. 2. 3. 4. 5. 6. 7. Supermicro 4U CSE-846E26-R1200B Rackmount Chassis / Rails Supermicro X8DAH+-F Dual Xeon Server Board / Intel 5520 / IPMI (2) Xeon X5650 CPUs 6 Core Westmere Processors (16) WD2003FYYS 2TB 7200 rpm Hard Drives 24 GB (6x4gb) DDR#-1333 ECCR Memory (2) LSI 9212-4i4e HBAs MegaRAID SAS 9280-4i4e with BBU’s Storage Cost 37 Total cost of a unit is $13630.
