StarWind Storage Appliance requires improved integration, easier setup, better insights, and feature parity between demo and paid versions.
We would appreciate a built-in transparent failover in the next release to eliminate the need for a separate metro cluster.
I'm eagerly anticipating the roadmap's promise of introducing multiple controllers, which could significantly boost scalability and resilience.
We mostly rely on long-term releases. We don't need the most up-to-date features, but we need a reliable environment.
The main concern is pricing, which could deter some customers; addressing this would enhance its appeal.
The system should move towards AI-driven optimization and enhance S3 object storage capabilities.
System downtime can disturb the entire ecosystem and impact all applications.
 

Setup Cost

Enterprise buyers see Pure FlashArray X NVMe as a justified premium investment due to performance and comprehensive licensing.
Nutanix Unified Storage offers competitive pricing, valued for features and ROI, but may be costly for smaller users.
StarWind Storage Appliance is praised for its affordability, straightforward licensing, and excellent value compared to competitors for SMEs.

Jaehoon Oh - PeerSpot reviewer
Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades
I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.
Amarnath Charugundla - PeerSpot reviewer
Unified management and cost-effectiveness lead to positive experiences and future savings
Improvement is necessary wherein the memory or storage should not breach 90%, because if breached, it becomes unmanageable. We have to set alerts or CPU triggering for 95% for the first warning. Other activities on nodes or file systems should be properly maintained. We must monitor the dashboard for P1, P2 alerts in the Nutanix Unified Storage (NUS) file share system including SMB, NFS, objects, and blocks. Attention should be maintained for any alerts such as CPU, memory, and RAM alerts, as exceeding these creates issues within teams. If triggered to 95% and forgotten, it crosses the SLA breach, causing disturbances to application, web, and platform teams. Continuous monitoring on the Nutanix dashboard is essential. Even a highly experienced person in Nutanix Unified Storage (NUS) cannot provide a 10 rating out of 10 because it is a vast system. I would rate it eight from my perspective.
Kishore CA - PeerSpot reviewer
Offers stable performance even with a single node failure and manages everything with just two nodes.
The only drawback is that it takes a bit of time during initial synchronization, especially after restarting the environment. This is a potential area of improvement. There's a synchronization time, but it takes time. Initially, when we start the first environment deployment, it starts synchronizing between the storage. So, it is taking time. One thing is that even when you restart. Let's assume that the synchronization is completed and the storage is synchronized. Both storages are fully synchronized, and it is in sync mode. Now, if we want to restart both nodes, there is a case for maintenance purposes. You took both nodes for maintenance, and we rebooted it. Then, it should not synchronize again. It should be a checksum. And if there is a checksum match, there should be no synchronization again. So, one thing that should be taken care of. Another thing is that I used freeware- the community version, free license, which we deployed using PowerShare. In that case, it was very difficult to bring back another node when one node was faulty. Let's assume that both the nodes are working fine. And we found one node faulty. And we destroyed all the volumes in that and tried to bring it back. So that was a difficult factor. The final solution is that we were not able to bring back the failed node. So, we reconstructed a new data source for that. That is another drawback. In future releases, I would like to see the integration with VMware or some other things as a plugin model for VMware.
