Customers always have their issues resolved promptly.
Pure has good storage.
The support team is familiar with the product and is available on-site during support times, which improves our experience.
Dell solutions are backed by excellent service and support.
The technical support sometimes takes three to four days to get hardware to facilities.
 

Scalability Issues

Sentiment score
7.1
Pure FlashArray X NVMe offers scalable storage with low latency, easy upgrades, though capacity customization and high costs are noted.
Sentiment score
7.8
Dell Unity XT is favored for its scalability and ease of upgrades, despite lacking high-end performance for some users.
Sentiment score
7.3
Nasuni offers scalable, user-friendly data storage, efficiently meeting diverse organizational needs and supporting physical or virtual deployments.
It is highly scalable.
It is suitable for both medium-sized and enterprise businesses.
It hasn't broken down anytime in the last six to seven years, despite hurricanes, earthquakes, and power outages.
Dell Unity XT is quite scalable and can be scaled up to the petabyte level.
For NetApp, we can recommend the FAS 8000 series.
I rated the scalability as seven because even though the solution can scale, load balancing must be done manually, as it's not automated.
 

Stability Issues

Sentiment score
8.1
Pure Storage offers exceptional stability and reliability with outstanding support, consistently achieving high user ratings for performance and service.
Sentiment score
8.5
Dell Unity XT is praised for stability, offering reliable performance and easy maintenance, with improvements post-initial bugs.
Sentiment score
8.2
Nasuni is praised for its stability, offering reliable performance, minimal maintenance, and flexibility with virtually no downtime issues.
During the eight years, there have been no problems such as hardware failure or stopping.
I would rate the stability of the solution as a ten out of ten.
I would rate the stability of the product at seven out of ten.
I would rate the overall stability of Dell Unity XT an eight out of ten.
 

Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
Dell Unity XT needs improved deduplication, compression, integration features, support, affordability, and simplified management for enhanced user satisfaction.
Nasuni struggles with cloud integration, performance, and user experience, needing improvements in data retention, security, and analytics.
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.
In the future, if Dell storages include this option, especially for Unity, it would help us target SME or medium enterprises for quicker closures and support the sales team.
I believe if Dell can integrate AI to predict potential failures, especially in hardware like hard disks, that would be very useful for proper maintenance.
The pricing is a bit higher than expected.
I suggest Nasuni improve their syslog forwarders to support TCP protocol, as it's more secure than UDP, which is plain text and not protected at all.
 

Setup Cost

Enterprise buyers see Pure FlashArray X NVMe as a justified premium investment due to performance and comprehensive licensing.
Dell Unity XT is competitively priced, offering robust features and support, suitable for mid-range budgets despite transparency concerns.
Nasuni offers competitive pricing with flexible cloud compatibility, licensing per terabyte, and cost-effective enterprise solutions.
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.
It is priced at around or under $50,000.
The cost is not cheap nor expensive.
Commercially, Dell Unity XT is viable and competitively priced.
I prefer solutions with lower pricing.
 

Valuable Features

Pure FlashArray X NVMe offers exceptional performance, reliability, scalability, and seamless VMware integration, enhancing workload efficiency and user experience.
Dell Unity XT is praised for its simplicity, performance, reliability, scalability, and cost-effectiveness, ideal for mid-range companies.
Nasuni provides scalable cloud-based file management with global file locking, data security, and efficient disaster recovery features.
Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator.
The platform's robust features include excellent sustainability tracking, and a comprehensive dashboard offering insights into IOPS, bandwidth, performance, and virtual activities.
Its data compression feature is the best that we have ever seen.
It helps with data cost management and is seen as a mid-range product with good performance.
We installed the Flash, which makes our IO operations fast and efficient.
If their growth is not significant, we might suggest mid-level Unity storage like Unity 300.
The features I find most valuable in Nasuni are the unlimited snapshots, antivirus capabilities, auditing, and ransomware protection.

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.
Syed Habib - PeerSpot reviewer
Efficient data replication and fast IOPS have improved operational performance
Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.
Barry Sunanan - PeerSpot reviewer
It helped us save 40 to 45 percent on some types of data
It can provide a 360-degree view of your data, depending on how you implement it and whether you're storing your data in Nasuni. However, if you're working with multiple cloud providers, I don't think it's mature enough to provide a 360-degree view of what's in AWS, Azure, and Google Cloud. I think it can do it, but it's still a lot of scope and range fitting. Given that Nasuni storage is actually cheaper in some areas, it made sense for us to move a lot of our data away from Microsoft. Nasuni gave us more of a 360 view of that particular data type. Other data types are a little different because the company went in a direction where they wanted to store some stuff in an AWS S3 bucket rather than a file storage system. An S3 bucket has its advantages, but if you were to store more of your data in Nasuni, you would get a wider 360-degree view of it rather than on several cloud providers. I have data in AWS, Google, and Azure, and I would like to see a wider view of all the data stored across these three top providers. Currently, I use it for AWS and Azure, but I couldn't use both of them at the same time. I think Nasuni could have better visibility across these different areas. I had to take my data out and then do some analysis to get the costs. It would be helpful to have more built-in analytics tools to compare the storage costs between the various cloud providers. I would also like some graphing capabilities. We had a tool called Grafana that we used for graphing. I think some more visual analytics like that would be nice.
