Data storage across all organisations is growing exponentially and “large” data is becoming a costly and growing problem.
How do you calucate the Total Cost of Ownership per gigabyte of storage – our breakdown of this is as follows based on analysis of customer installations, cost of storage (based on EMC hardware) and administrative and backup costs:
| Initial Cost | Depreciated Cost per Annum (4 Years) | |
| Cost of Storage Hardware per GB | £4.61 | £1.15 |
| Cost of Backup Hardware per GB | £9.52 | £2.38 |
| Cost of Administration per GB Current | £0.24 | £0.24 |
| Total Cost per GB | £14.37 | £3.77 |
This gives a Total Cost of ownership per GB of £14.37 and an ongoing TCO of £3.77
Some customers have used figures as high as £18 per GB for TCO so a range may be appropriate.
