Real Cost of Storage White Paper 9 Copy data is a massive burden upon cost and until recently was an accepted 'tax'. This needn't be the case. Addressing it can go a long way to reducing storage costs without a huge disruptive architectural transformation process. Smart new copy data virtualisation technologies can reduce data storage costs by up to 75% in a traditional Mode 1 infrastructure model, and great data storage efficiencies can be gained in Mode 2 if the application is built within the guidelines of 12 factor app development. Make the True Cost of Data Storage Services Comparable To truly determine the cost of your current or desired data storage services include the costs for all of the following. • The primary storage. The actual hardware device or cloud service the data set is recorded to. • The presentation layer. The software and hardware used to connect and present the storage in a format that is useful to the application e.g. block, file or object. • Durability. What level of protection the data set is afforded. What Data Storage Services are Appropriate? Having found a cost effective solution, determine whether it is fit for purpose for the use case. Considerations in this instance will include. • Data type. Structured or unstructured. • Presentation. Block, native object, or file system. • Performance. IOPS and latency, which in turn will determine proximity to the application. • Cloud Readiness. The application needs to be truly cloud native to exploit the economies of a Mode 2 environment. • Sovereignty. Be sure to understand any territorial mandates for compliance. • Use case. Not everything needs to fly first class. Some production-subordinate services might be enhanced with smart technology or lower service class deliverables. Advice for Cost-Effective Data Services Identifying the real cost of a data storage service is essential but need not be difficult. Here are six suggestions to get you started. Understand the data storage service required for each unique use case. Then investigate the means by which that service could be delivered e.g. on-premises, managed service, public cloud. Armed with this information, organisations can make fair comparisons and informed choices. Include CAPEX and OPEX costs. Both CAPEX and OPEX costs such as power, datacentre space, support and maintenance, consumables (particular relevant to removable media such as tape), management/operations time must be considered. If comparing a cloud service solution, factor in the uplift in network costs that might be required to deliver the requisite service availability (dual routing), security, load balancing, bandwidth and performance. Most importantly look for the hidden transit and egress costs that often catch people by surprise. Consider the intangibles. These are costs that won't specifically appear on any data services bill of materials: − The cost of money – how much would the business recognise in deposit interest or loss of opportunity cost if the cash disposed to a capital intensive solution were retained in the bank for more useful business purposes? This may suggest using an OPEX based solution such as cloud, managed service or lease finance is best. − Agility – what impact can a more agile service have on an organisation's ability to respond to market change? How can an agile service deliver competitive edge? Can that value be quantified? ■ Physical ■ Software ■ Durability 1 2 3
