Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
Users desire NVMe support, improved UI, active-active controllers, enhanced features, better integration, and flexible pricing for HPE Alletra Storage.
Nutanix Unified Storage needs improvements in scalability, customer service, integration, and features like analytics, data protection, and user interface.
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.
They shouldn't strip out anything from InfoSight. That is really helpful software to see how the storage arrays are performing and has helped us do a lot of troubleshooting.
They would like to have one tool that can take them everywhere. There should be a single pane of glass.
Most importantly, there is going to be the flexibility of moving compute and storage on Alletra MP.
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.
HPE Alletra Storage's pricing is seen as high but justified, offering both predictable and flexible licensing options.
Nutanix Unified Storage offers strong ROI and robust features but may be cost-prohibitive for smaller businesses with complex licensing.
While the prices may be higher than those of other vendors, we see it as a market leader with benefits.
The support can be a bit pricey, but the solution is more cost-effective than anything else out there.
I would give it a nine out of ten in terms of costliness.
For future use, we bill based on device consumption rather than the traditional datacenter model.
The predictability of having that one-time cost is everything for the data center.
It's expensive.
Compared to buying three or four vendor solutions, it is much cheaper.
The cost has doubled for the same amount of data, which was a challenge when presenting use case justifications for the increased cost.
Nutanix Unified Storage (NUS) has definitely helped reduce our total cost of ownership.

Featured Reviews

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.
Anand Algesan - PeerSpot reviewer
Provisioning and encryption ease improve data storage efficiency
To improve HPE Alletra Storage, it needs to have a true active-active controller; it claims to have an active-active controller from the back end, however, the second node is pretty much sitting there doing nothing. The MV 10000 series, which is the next series, is an improvement to HPE Alletra, and HPE is already doing that. In the next release, I would prefer to see better dedupe features; I know other companies do excellent dedupe, and they have protection group policies, meaning you have immutable data in case of a ransomware attack. If you're on the SAN, it should give you a way to protect that data without being erased. Other vendors have that capability built-in, ensuring that you can't erase the data, so features similar to that would be great.
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.
