Pure Storage FlashBlade is scalable.
There are between 5 and 10,000 people using it in our organization.
There are no limits to scalability, which is essential for central storage.
The scalability of Microsoft Storage Spaces Direct has been extremely good, allowing for both vertical and horizontal expansion.
It has limitations; it's configured for eight servers per site but can be scaled to 16 servers.
The scalability of Microsoft Storage Spaces Direct is limited.
In case there is any issue with any blade, the data is moved to another.
Microsoft Storage Spaces Direct has been incredibly stable as long as it is configured correctly; incorrect configurations lead to surprises, which is common with any product.
Storage Spaces Direct is stable enough, however, there can be some glitches.
Technical support definitely needs significant improvement.
Its configuration should be easier.
One way Pure Storage FlashBlade can be improved is by having more compatibility between the FlashArray and FlashBlade.
there should be improvements in how to get and filter logs
The area of DataCore SANsymphony that has room for improvement is the support.
DataCore SANsymphony can be improved with high availability as it offers synchronous mirroring between physical and separate sites to ensure business continuity and disaster recovery.
The licensing for Microsoft Storage Spaces Direct could be improved to be clearer, as calculating license requirements requires significant expertise; even Microsoft resources do not provide the full picture needed for licensing, leaving gaps that become evident once we move to deploy solutions.
One year ago, I had a problem, and it was difficult to identify and solve due to a lack of tools.
The performance of Microsoft Storage Spaces Direct is challenging when trying to support both NVMe and SATA SSDs, and there are problems regarding performance that need to be addressed.
The pricing of Pure Storage FlashBlade is expensive compared to other products I used from other companies in the past, but one benefit is that they have built-in ransomware protection.
Regarding pricing, it is okay; we needed exactly this in size, and the price was a lot lower than competitors, making it good for us.
They have made some improvements regarding the pricing, but it's still too expensive.
The cost changed from a perpetual license to a subscription model.
I find the Azure Local to be a bit expensive, especially due to hidden costs associated with additional tools needed for monitoring and alerting.
Pricing is an advantage of Storage Spaces Direct.
We can plug in many blades, and we can have data up to one terabyte.
The best features of Pure Storage FlashBlade include better throughput and better performance.
Pure Storage FlashBlade's scalability is one of the most valuable features, and importantly, it always works, allowing for seamless upgrades.
Customers can extend storage with flexibility, as one is not obligated to purchase hard disks or controllers from the same storage vendor.
DataCore SANsymphony's ability to enhance storage utilization is very good because it's agnostic and it can be deployed on every environment, which is perfect for my clients.
This flexibility and scalability have helped our organization in practice because it is important for us as it decouples the storage management software from the physical hardware, creating a software layer of intelligence.
The redundancy and fault tolerance features of Microsoft Storage Spaces Direct have helped maintain data integrity and availability in my company by providing multiple copies through three-way mirroring, delivering hardware performance needed for our applications, which is crucial.
For caching, I use disks with more total bits written, which protects the main storage because writes are combined.
The price performance is the best advantage of Microsoft Storage Spaces Direct.
