We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

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
1.0
Hitachi VSP E Series' ROI varies by use case, excelling in high IOPS workloads, with efficient manageability and support.
Sentiment score
6.9
Nutanix Unified Storage boosts ROI by cutting costs, enhancing efficiency, improving management, and strengthening data security for users.
By opting for the gold subscription every three years, you get a free upgrade to the latest controller release.
If you wait more than seven years to buy another one, you get a return on your investment.
Return on investment depends on the use case, especially for workloads demanding high IOPS.
For me, the biggest return on investment when using this solution is that we do not have to have much support staff to run it.
The scalability challenge with previous systems is lessened with Nutanix since we can expand by adding new hardware without needing migrations.
We are saving approximately 20% to 25% compared with the competition.

It automatically triggers tasks, causing performance issues.
 

Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
Hitachi VSP E Series is costly, has a complex interface, and requires unified storage and improved marketing and documentation.
Nutanix Unified Storage requires enhancements in implementation, analysis, technical support, FTP compatibility, management, integration, security, and usability.
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.
I recommend creating one product for unified use, like other manufacturers, which includes both block and file storage in one platform.
Hitachi is quite expensive, and small to medium-sized organizations usually do not purchase it.
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.
Hitachi VSP E Series is an enterprise-level, costly storage solution ideal for banks requiring high performance and availability.
Nutanix Unified Storage offers competitive pricing, valued for features and ROI, but may be costly for smaller users.
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.
Hitachi is generally expensive, providing products designed for enterprise customers like banks with transactional workloads.
The solution is expensive, which can be considered a con.
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.
Paolo Brega - PeerSpot reviewer
Rated highly for robust integration and diverse features
Currently, we are not approaching the virtual storage. We are working with Hitachi and Pure Storage; in some cases, we work with NetApp. We work with more or less all the stack of Hitachi products, starting from the small machine up to the VSP, the big family, the high-end, depending on the customer, the end user. We have very poor experience with Hitachi VSP E Series because we don't have big customers, just a couple. We had experience with VSP, specifically the E Series. We don't take care of data protection features from Hitachi because our customers do not generally involve us in this area as it is not our focus. Integrating Hitachi VSP with a hybrid cloud environment is not particularly complex. The automation process is handled by our storage administrator; I support them in the choice but don't work directly with that. I would rate Hitachi's pricing around a three, stability an eight, and Hitachi VSP's scalability a 10, as you can scale whenever you want. Hitachi VSP can compete absolutely on the market. When comparing solutions, Hitachi VSP is the best for me. I have rated this solution 9 out of 10.
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.
