Your power as a buyer is stronger before the sale closes: Ask for what's required to effectively evaluate storage vendors' system performance.
Storage vendors love to talk about their performance specifications, such as IOPS, throughput and latencies. The problem is that there's no standardization of those specifications among vendors.
There is little guidance as to how vendors measure or come up with those storage system performance numbers or how they correlate to a specific workload or application. In addition, vendors measure performance in different ways. Add in different storage types -- block, file and object -- and it gets even more complicated.
You, the IT pro, are essentially left to your own devices to figure it out. So, how should you compare performance?
There are many different distributed file systems available, so careful analysis of the options, as well as good project management, helps ensure a successful installation.
Distributed file systems enable users to access file data that is spread across multiple storage servers. Key features -- including application and platform support and storage type -- differ from one product to another, so it's crucial for organizations to make a vigilant comparison of distributed file systems.
Users must examine their requirements and the differences among distributed file systems, evaluate the many products available on the market and then commence a systematic process for selection and implementation.
