The biggest problem is that it is not able to provide block storage. It can consume block storage, you can put it on from the storage and present the span over the fiber channel or iSCSI. The problem is that they have not been able to provide block storage consumable to the customer host. This is only a side-based solution. We can install the GPFS into the customer environment but I don't think that is the best solution. The initial setup has room for improvement, it is not straightforward. Spectrum scale is very good from the performance perspective, but from the application perspective, you have to take care if you want to use a database as a service that you can consume. For example, a database, or being able to read and write it, doesn't have a deployment solution. It is missing.
The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers. It is not always easy to sell this product because certain aspects seem complicated for the customer.
