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…

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.

Quotes from Members

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

Pros

"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."
"The solution uses newer technology for deduplication and compression."
"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."
"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"It has good, reliable, fast storage."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."
"The solution's initial setup process is easy."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"The solution is very easy to set up."
"Its initial setup process is easy."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"Lenovo ThinkSystem DE Series is quite an elementary box, no frills. It does not have all the functionality of the DM but it is acceptable, it does its task. It integrates pretty well."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"Nutanix has excellent product documentation available on their portals, written in simple, easy-to-understand language."
"What I found to be the most valuable features were better performance and uptime."
"The capacity is very good. They use fewer nodes than before. Each node is isolated with the CPU with the performance. It is a cluster node but works separately, so the performance will be tripled."
"Whenever we have some necessity in terms of capacity and expansion of infrastructure, it's like a Lego system where they can just place in some more nodes and our needs are met."
"My opinion is that this solution has very good stability."
"The most valuable feature is that it is highly available, solving the pain-point of delaying updates to Windows-based file servers during production hours. And then the second one would be ransomware protection and analytics. It gives you great visibility and protection on your file shares that are otherwise the most common sources of vulnerabilities."
"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."
"Redundancy and availability are valuable. We have several nodes, so it stays up, and there is redundancy. Then there is availability."
 

Cons

"Adding some functions to the product would be beneficial."
"There are some challenges with data encryption and reduction."
"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"In the future, I would like to see integration with enterprise backup systems."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"The features are limited."
"Its performance could be faster."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"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."
"It would be useful to have structured solutions replicated to other sites."
"There could be a snapshot feature in the solution."
"The solution could be more scalable, although it suits our present needs."
"The implementation is a little bit complex and should be made easier."
"I believe that one of the most complicated parts of Nutanix Unified Storage is the configuration of the DNS issue in Active Directory. Sometimes it is a bit complicated to troubleshoot or detect an error when integrating it with Active Directory."
"When it comes to Nutanix Files, one thing that would be great is a slightly easier way of managing snapshots and restore points, especially when a third party is involved."
"According to the keynotes announced by Nutanix the previous day or this morning, the data storage for Kubernetes requires improvement as it has a few shortcomings in the area of operations."
"Pricing can always be better."
"Nutanix needs to improve their cybersecurity options at the storage level."
"The GUI is easy to use, but it's complex to do tasks from the command line. That is one way they could simplify things for the engineers. People tend to use a graphical interface more than the command line interface. If anything goes wrong, we need to do troubleshooting from the CLI. It would be nice if there were more ways to fix issues within the GUI."
"I have heard that there have been latency problems."
 

Pricing and Cost Advice

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."
"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."
"Our licensing fees are $500,000+ USD."
"The product is expensive."
"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."
"The licensing is on a yearly basis."
"Given its price, Pure is not the first option."
"With VMware, we pay $300,000 annually."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The pricing for this solution is good compared to HP or Dell EMC."
"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."
"The solution's price could be better."
"We have a five-year contract for providing support."
"The pricing is fair and low compared to other products in this category."
"The best thing about this solution is its price, which reduces our costs."
"It is an expensive solution."
"Nutanix Unified Storage was cheaper than other solutions we evaluated."
"I hope that it will stay the way it is. We have seen the changes in VMware and what happened to them. I have heard that Nutanix will raise the prices, but I hope that they will not do that."
"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."
"It is very good. It is much more competitive than a dedicated storage platform."
"With all of the Nutanix equipment, the licensing is expensive. We operate in the enterprise space, but we're a midsized company. At times, the price tag is a little bit shocking for a company with only 35 employees. We're not a Fortune 500 company, but we deal with Fortune 500 drug and energy companies. We have to play in that enterprise space if we're going to have enterprise customers. I'm very price-conscious, but I understand that if I want the best, I've got to pay the price."
"In my opinion, the product is fairly priced."
"Nutanix is very competitive."
"Nutanix Unified Storage is competitively priced. There aren't any competitors that can do much better for the same price."
