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.
Juan-Contreras - PeerSpot reviewer
Ensures streamlined management, simplified infrastructure, and efficient data handling
It has effectively managed our unstructured data, including audio and video files. We've experienced smooth operations without any complaints regarding uploading or downloading videos. While video usage isn't as frequent, we primarily utilize it for downloading videos related to specific incidents for administrators or our police department. We've encountered no issues uploading files of any kind. Transitioning from VMware to Nutanix has highlighted the overall flexibility of Nutanix's platform. Unlike VMware's three-tier system, Nutanix simplifies the learning curve by streamlining operations. The update process, in particular, has been favorable, with no critical issues encountered. The resiliency of Nutanix hasn't been thoroughly tested in our environment so far. However, I routinely check fault tolerance settings to ensure they meet our requirements. During the update process, I've observed critical errors occur as hosts restart, but Nutanix's self-healing mechanism handles these issues seamlessly. The benefit of using Nutanix is evident in several ways. Firstly, we've effectively compressed our storage while significantly expanding our overall storage pool. Previously, our service had a capacity of twenty-five terabytes, but with Nutanix, we've scaled up to a hundred and twenty terabytes physically and approximately fifty terabytes logically. This expansion has been accompanied by noticeable improvements in performance, particularly with reduced latency and IOPS well within the boundaries of our equipment. All our resources are centralized in a single location for managing and running storage: our data center. We operate three Nutanix nodes within this center, effectively managing everything from one central location. We don't have any other locations outside of our data center running a Nutanix cluster. Nutanix's capability to eliminate silos within our organization's storage infrastructure was discussed during our recent call with the engineer. Although we haven't explored this feature extensively yet, there's a forthcoming project where we anticipate leveraging it.One thing I'd appreciate is having a desktop application similar to what VMware offered. With VMware, I could download a separate client program onto my computer, allowing me to log in directly rather than accessing the host through a browser.

Supercharges enterprise storage by way of highly optimized hardware, comprehensive data management and a feature rich interface.
During their early years, I was a member of Pure's Customer Advisory Board. In addition, when we first adopted Pure, they did not have replication GA yet. We got into their beta testing program and help them work out certain issues with that technology. One weakness I can say the array has, still to this day, is limited control on scheduling snapshots. Depending on the type of replication schedule you are building, you may or may not have control on specifying the start time of a given replication schedule. This is not a very big problem in the grand scheme of things, but something nonetheless that has bothered me about the scheduler in general. Another area for improvement would be automatic host alias creation. Other platforms such as EMC Unity/PowerStore will automatically detect the host name, create a alias for it and associate the logged in HBA's to it. Pure does not do this for you and as a result, requires manual configuration. This can be very time consuming especially when you are deploying a large number of new servers.

Quotes from Members

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

Pros

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The most valuable features of this solution are its ease of use and performance."
"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 most valuable feature of this solution is its ease of use."
"The solution is scalable."
"One of the best features is the support, which is excellent."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"Overall stability is very good. It is a very stable solution."
"Nutanix Unified Storage is a stable solution that provides good storage and efficiency."
"Nutanix's analytics provide better insights into all of our files."
"Management-wise, it has made work a lot easier. It is all in one place physically. It is much better now."
"I appreciate its storage licensing model, as it offers flexibility."
"We have virtually zero downtime with Nutanix. It updates itself, and we can easily move machines from one cluster to another."
"I like its interface. It is very interactive and simple to use."
"The inclusion of it in the Nutanix Objects Storage platform simplifies my process as I am no longer required to acquire a separate platform. Instead, I can simply purchase additional licenses as needed. All management can be performed from a single unified interface, making it a convenient and streamlined experience."
"Some of the features that we use include replication and snapshot capabilities, especially from remote locations to our data centers. The main benefit our company sees from using Nutanix Unified Storage is simplification. In the past, we used three-tier solutions with a lot of complexity and operational overhead. Now, we want to focus on the layers above. I want to have storage available, but I don't want to have to think about it. I want it to work without any issues."
"The first year, we started out with one or five terabytes and it took what was 20 terabytes of storage down to less than one terabyte."
"The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side."
"The data reduction technology part of the scalability has been impressive, like its ability to host additional workloads, volumes of data, and databases."
"The dashboard is nice. It is easy to manage compared to other storage solutions such as Dell EMC."
"The most valuable feature is it never goes down. We can expand and create volumes."
"The simplicity of it. The performance is good, but the simplicity is the best thing. Storage management is quite complex, but Pure Storage is easy to manage."
"There was a dramatic improvement in operating costs just as a result of the environmentals and space, let alone the cost of the unit itself."
"The predictive performance analytics are good."
 

Cons

"We would like to see VNC integration or be able to use Pure Storage with VNC."
"Maybe the price can be reduced since the solution is very expensive."
"The tool's pricing is higher than competitors."
"I would like to see replication and DR features in the next release of this solution."
"In the future, I would like to see integration with enterprise backup systems."
"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"The UI for this solution needs to be improved."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"It is challenging to configure access control settings."
"The documentation on the support site needs to be improved."
"Perhaps Unified Storage could be improved by including artificial intelligence to make searches more effective. Also, if someone has access who shouldn't, it could automatically update, so I do not need to physically remove permission. The platform could do it automatically. AI could make it more self-service."
"Another aspect that needs improvement is continuous protection against security threats such as ransomware and potential data leakage."
"The solution is very expensive."
"We have some problems with Nutanix Unified Storage's support because they asked us to change our hardware."
"Some of the new features in the tool cannot be used with just one click, as was possible in the past."
"The feature request I have is for the consistent improvement of how user account permissions are assigned in Nutanix Unified Storage."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool."
"The price of this solution could be improved."
"In the next release, I would like to see file-level encryption."
"The file functionality could be better."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"Pure Storage support could be a little better."
 

Pricing and Cost Advice

"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."
"The support cost per array is about $20,000 a year for 24/7 support."
"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"Our licensing fees are $500,000+ USD."
"As far as the licensing costs, everything is included in the license."
"With VMware, we pay $300,000 annually."
"Given its price, Pure is not the first option."
"The solution's pricing is fair."
"It's not the cheapest solution. It's in line with other solutions, but it offers features that the competitors don't have at any price point, especially with regard to analytics and ransomware prevention. No one else has any sort of object-based storage available. Nutanix Unified Storage is a lot more feature-rich. This is a situation where you get what you pay for."
"From what I hear from the management, Nutanix Unified Storage has comparatively decent pricing."
"I'm happy with the cost and licensing because I don't have big volumes."
"Nutanix offers different pricing options, including Ultimate and Ultimate Pro."
"If we compare the cost of Nutanix Objects Storage to other solutions such as VMware licenses, our current choice is Nutanix Objects Storage. This solution is more cost-effective. However, adding VMware to Nutanix would not be a cost-efficient decision, which is why we do not use it anymore."
"The cost of Nutanix Unified Storage can be prohibitive for some small and medium-sized businesses, making it challenging for them to adopt the product."
"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."
"There are no licensing fees or other costs."
"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."
"We are finding the TCO of flash to be lower than SSD implementations."
"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"The pricing of Pure Storage FlashArray is reasonable."
"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."
