Popular Comparisons The most valuable feature is the integration of all parts in Prism Element, the browser-based management tool.
In terms of scalability, adding a number of nodes, I find that it will not be any issues.
Popular Comparisons The iSCSI protocol is quite simple to configure.
The fact that I can now count on a true failover solution is what is most appealing.
Popular Comparisons The full suite of redundancy gives a nice sense of security for the whole environment.
The option to deploy a hyper-converged system without an expensive storage switch was a benefit.
Popular Comparisons The interface is user-friendly.
It provides high performance and business-critical storage.
Popular Comparisons The flash ability, in terms of tiering and caching, is amazing
It's mainly about the storage expansion, like in hyper-converged solutions.
Popular Comparisons A very flexible solution.
All of the administrative tasks are easy and everything is centralized.
Popular Comparisons I like the fact that we can simultaneously upload the virtual tapes to different cloud providers, and the settings can be adjusted to speed up the upload times even further.
Popular Comparisons There are many benefits to this solution. Storage virtualization and the ability to migrate massive amounts of data to other systems without impacting your client are the most valuable. It is non-disruptive for my users. We migrated 350 terabytes of data in one night to a new machine without a small system going down and a single user complaining about the performance. You have to fine-tune a lot of storage machines constantly for performance and for making sure that they are optimal, but IBM Spectrum Virtualize does this by itself. It does the adjustment on its own, and it does it right. That's what makes it different. I had a huge VSP from Hitachi, which is also a type of virtualization-based engine but with a decent size. It was a continuous performance-tuning exercise. I never had that issue with IBM Spectrum Virtualize.

Rather than evaluating based solely on feature set, make sure the SDS platform will meet all of the business objectives.
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.
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.
Company Reputation, Costs, scalability; features for Cloud or DR.
Price and support for when problems happen.
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.
