Eugene Hemphill - PeerSpot reviewer
Helps to save money and resources with the data compression feature
One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.
Gastone Canali - PeerSpot reviewer
Provides good stability and is reliable in terms of performance
The solution is reliable in terms of performance They should include a snapshot feature for the solution. We have been using the solution for two to three years. The solution is stable. We have 60 solution users in our organization. The solution's initial setup process is easy. It takes three…

Pricing challenges overshadow efficient data handling and fast deployment
In terms of improvement areas for Nutanix Unified Storage (NUS), pricing is a significant issue, and another aspect is that the export of Nutanix backups does not support CD-ROMs, which is a disadvantage. Currently, it only supports QZ bus types for backups, which limits compatibility. When comparing Nutanix Unified Storage (NUS) with other solutions in the market, it falls short because it only supports iSCSI backups, while competitors also support QZ, iSCSI, fiber channel, and NVMe storage. The solution requires no maintenance for patching since it is designed effectively, but Nutanix Unified Storage (NUS) does not support fiber channel connectivity or external attached storage through NAS, limiting its compatibility. Additionally, technical support response time and efficiency are lacking in comparison to competitors.

Quotes from Members

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

Pros

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"It has benefited my organization because it has reduced time to insights."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."
"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"The high availability of the product is the most valuable feature."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"The solution is very easy to set up."
"The solution's initial setup process is easy."
"Lenovo ThinkSystem DE Series is simple to use"
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"Nutanix Unified Storage is a stable solution that provides good storage and efficiency."
"It is very scalable."
"My company has benefitted from Nutanix Unified Storage because we have everything in a centralized place. With Prism Central, we can go to the console files and do what we have to do."
"Nutanix Unified Storage (NUS) is very fast in terms of migration and data access with respect to VM, OS, and storage, experiencing a 30% faster performance compared to VMware."
"We migrated over to Nutanix and saw an immediate improvement in the performance."
"Nutanix support deserves a rating of nine out of ten."
"The deployment was very easy."
"What I found most valuable in Nutanix Files Storage is its high availability and ability to scale out with many VMs."
 

Cons

"The UI for this solution needs to be improved."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"There is room for improvement in the pricing of the product."
"The software layer has to improve."
"There are some challenges with data encryption and reduction."
"They could add more support for file storage and different types of storage."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"Improvements can be made to the product's performance."
"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."
"The solution could be more scalable, although it suits our present needs."
"It would be useful to have structured solutions replicated to other sites."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"Its performance could be faster."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"There could be a snapshot feature in the solution."
"We have had to deal with some infrastructure and general cluster issues but these issues don't impact storage."
"Since it's part of Prism, I might suggest integrating the management console into Prism instead of having a separate console; that's the only change I would recommend, and it's not a significant issue."
"When considering the difference in cost benefits, if you consider it only as a storage solution, you may find it expensive."
"The dashboard can have more details and be more useful."
"Lowering the price would improve this product."
"There is an occasional language barrier between some of the technicians, which can be challenging; however, that doesn't prevent us from being assisted, as they can remote in and use Pulse to view our cluster and gather logs and reports."
"For P1 and P2 alerts in the Nutanix Unified Storage (NUS) file share system, including SMB, NFS, objects, or blocks, we must maintain vigilant monitoring. This is crucial because system downtime can disturb the entire ecosystem and impact all applications."
"Some of the new features in the tool cannot be used with just one click, as was possible in the past."
 

Pricing and Cost Advice
