ROI

Sentiment score
1.0
Organizations reduced costs and improved performance with Pure FlashArray X NVMe, achieving quick ROI and efficient resource management.
Sentiment score
8.5
Huawei OceanStor offers significant cost savings and performance improvements, with some organizations seeing returns and efficiencies within a year.
Sentiment score
6.9
Nutanix Unified Storage boosts ROI by reducing costs, enhancing uptime, scalability, and efficiency, while improving data management and productivity.
By opting for the gold subscription every three years, you get a free upgrade to the latest controller release.

Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
Huawei OceanStor users face challenges with integration, support, performance, and pricing, suggesting improvements in various technical and operational areas.
Nutanix Unified Storage requires upgrades in storage capabilities, ease of use, FTP compatibility, analytics, security, support, and pricing.
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.
Huawei currently lacks a solution for high-performance AI, unlike other companies like DDN, WekaIO, or IBM BlueStore.
The stated capacity was not a true reflection of the actual capacity.
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.
Huawei OceanStor offers competitive pricing and valuable features, though its licensing model may increase costs, yet remains cost-effective.
Nutanix Unified Storage offers competitive pricing, appreciated for cost-effectiveness, but may be expensive for small businesses or specific regions.
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.
Huawei is priced competitively, encouraging companies to consider it over other products.
Huawei OceanStor's pricing is very aggressive, making it highly competitive.
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.

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.
AmanullahMehmood - PeerSpot reviewer
Offers better price and features compared to its competitors
The technical support for the solution is very good. Huawei, in our region, has more than 2,000 employees in the office, and they mostly have post-sales engineers for storage, servers, and networks. Huawei also trains its partner engineers on the storage it offers. If a customer faces any problem, then a partner engineer will first resolve it. If an issue is not resolved in the tool, then Huawei engineers get involved, and the case gets lodged with Huawei's tech team, after whom a Huawei engineer will come. The partner, a tech team, and then a Huawei engineer get involved in the support process. I rate the technical support an eight out of ten.
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.
