We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
"GPFS monitoring is the best feature."
"The most valuable feature is the ability to share files across different platforms."
"We are using it for monitoring all of our storage."
"The high performance of the solution is its most valuable aspect. If you compare it to other storage solutions, it's much better."
"The most valuable feature is that there is no single point of failure."
"The most valuable feature are the caching capabilities using the storage class memory."
"It's mainly about the storage expansion, like in hyper-converged solutions."
"The flash ability, in terms of tiering and caching, is amazing"
"The biggest problem is that it is not able to provide block storage."
"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."
"Integration with other vendors is not available."
"It would be helpful if there was a graphical user interface that could walk you through the deployment process. The instructions surrounding setup aren't the best. They need to be more step-by-step."
"More optimization could be done in terms of mirroring."
"I think the online documentation needs a lot of work and so do the sizing tools."
"It is scalable, but only beyond two nodes. If I go for two nodes it's not scalable. I need to build a complete cluster from the beginning if I'm going for two nodes."
"Documentation management could be improved"
"The licensing is based on the number of terabytes."
"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."
"With the data center licensing and everything that is connected to that, this solution is relatively costly."
"Cost-wise the product is one of the more affordable within the category of products."
Storage Spaces Direct uses industry-standard servers with local-attached drives to create highly available, highly scalable software-defined storage at a fraction of the cost of traditional SAN or NAS arrays. Its converged or hyper-converged architecture radically simplifies procurement and deployment, while features like caching, storage tiers, and erasure coding, together with the latest hardware innovation like RDMA networking and NVMe drives, deliver unrivaled efficiency and performance.
