You have to know the converged infrastructure vs. the hyperconverged infrastructure, and the differences lie mainly in the SAN in a converged environment, making a SAN a single point of failure, as opposed to an HCI solution in which there is no single point of failure and can reach the same number of IOPs and higher than a converged infrastructure. However, many companies are slow to make the change for the initial investment cost, in the long run, companies choose HCI and know that HCI solution is the right one enters another analysis.
After evaluating all of the requirements, the first and main aspect should be reliability and data integrity.
The aspect that is most important depends entirely upon the business objectives and needs of the client. Some need scalability, some need a specific application compatibility, some need specific hypervisors, some need to focus on DR/backup capability. It's not a great question.
Company Reputation, Costs, scalability; features for Cloud or DR.
Price and support for when problems happen.
Rather than evaluating based solely on feature set, make sure the SDS platform will meet all of the business objectives.
Do a careful POC and make very very sure the solution does not corrupt data when you have a major storage issue like an array failure.
Start with the economics and in your evaluation criteria, stress not only the new features and capabilities being touted but on how much disruption will it cause to your current environment, does it protect and leverage your existing investments and is it software that can bridge different deployment models (serverSAN, pure software, appliance, hyperconverged or hybrid cloud) since we live in a 'hybrid' world and how much true agility it brings to meet change and growth. To often vendors tout specific new models or features and describe these new 'shiny objects' as panaceas, but the reality is often the new comes with a 'rip and replace' mindset that forgets about existing investments and how to add agility and future-proofing to your infrastructure to readily accept new technologies and absorb them within the overall management versus creating yet another independent silo to manage. Look at the economics and think big picture to avoid stop-gap solutions that actually add complexity and cost.
