Active Archival Storage - A Cost of Ownership Analysis
The technology choice for implementing deep and
active digital archives has historically been between tape and optical.
Content addressed systems that are based on commodity disk drives have
recently become available as an alternative.
The Enterprise Strategy Group (ESG) was contracted by
Plasmon, a leading optical archiving solutions
provider, to perform a third party analysis of the cost of acquisition and
ownership of each of these archival technologies – tape, optical, and
disk.
This analysis is based on the actual case study of a
financial services firm shopping for a 12 TB archive.The financial
services firm needed a solution to archive 8 GB of new data and handle
2,500 queries daily. The cost of acquisition and ownership was measured
over 3 years of operation. Only clearly quantifiable list prices were
included in this study to avoid the effects of subjective
interpretation.
