Choosing the right storage according to your needs could be a very long debate without a simple answer, because there are so many different types of storage solutions. As usual, you have to consider availability, scalability, performance, and manageability aspects, including some new capabilities such as data protection, data migration, security, and so on.
Traditional IOPS sizing could be too limited considering that most of the enterprise storage works with concepts more complex, such as data tiering, data reduction, and data locality; for this reason, it's always suggested you make a capacity and performance estimation using vendor-specific tools.
In most cases you will have storage with some flash technologies:
- AFA (full flash): This is where performance and storage latency could be critical and you want a storage with predictable throughput and latency...
