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.

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.

HPC CTO at a manufacturing company with 10,001+ employees

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

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 will quickly overcome all the hurdles you face, including network and latency issues."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"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 database workloads are pretty fast because I frequently move data from here to there."

"The solution is very straightforward to set up."

"Technical support has been helpful and responsive."

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

"The solution uses newer technology for deduplication and compression."

More Pure FlashArray X NVMe pros

"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."

"The initial setup is pretty straightforward. With a few clicks, you can stand up your storage. It reduces the overall life cycle of deployment within the ecosystem."

"The real-time alerts generated by this system enable us to swiftly address and mitigate such threats."

"Nutanix Unified Storage is easy for end users to access. They can use it like any other drive on their systems. We have mapped it in the user system so they can scan files and store them. They can use it just like an Android drive."

"The most valuable feature is the easy interface."

"The solution is stable and extremely easy to calibrate."

"The most important point is the simplicity of the API integration. We can leverage the API integrations and connect our hybrid-cloud network environment with Nutanix's cloud storage."

"Nutanix has excellent product documentation available on their portals, written in simple, easy-to-understand language."

More Nutanix Unified Storage (NUS) pros

"The solution is useful for machine learning and scientific applications, including computer simulations."

"This has been one of the most reliable storage systems that I have ever used."

Cons

"The tool's portfolio is minimal. It is expensive."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"We need better data deduplication."

"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."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"I would like to see replication and DR features in the next release of this solution."

"I'd like to see the product implement active replication for vehicles such as VMware."

More Pure FlashArray X NVMe cons

"The solution should increase its storage capabilities."

"The GUI is not user-friendly for new users and has room for improvement."

"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."

"While they are good and they do work, some of the snapshotting and tiering features are not as simple to set up as they could be."

"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."

"I haven't had any issues with the solution so far."

"We would love to see the analytics and ransomware protection extended beyond just file servers to virtual machines, but they have a different product that covers that."

"Another aspect that needs improvement is continuous protection against security threats such as ransomware and potential data leakage."

More Nutanix Unified Storage (NUS) cons

"The read/write ratio is an area in the solution with some flaws and needs improvement."

"The write performance could be improved because it is less than half of the read performance."

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 licensing is on a yearly basis."

"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."

"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."

"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."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"Given its price, Pure is not the first option."

More Pure FlashArray X NVMe pricing and cost advice

"My company is in Brazil, and making the payments in dollars is tough for our organization."

"The price can always be improved. As a customer, you always seek reasonable solutions within your budget, and they give us little to do a lot. My IT team always has to justify that we are choosing an optimal solution, so the price could be a little lower Maybe the prices could be a little bit lower."

"The solution's pricing is better compared to other products."

"The solution is highly-priced."

"The price of the license is expensive when comparing it to traditional storage."

"We are Nutanix partners, so it is pretty good. With the free terabyte that comes with the Nutanix clusters, we have started to build proposals for the clients. The price adjustment with the new policy of Nutanix Unified Storages seems attractive. Let us see if it has results."

"Nutanix's pricing is definitely much better when compared to other storage providers. That was one of the main reasons we switched to this platform."

"The pricing is a bit too high."

More Nutanix Unified Storage (NUS) pricing and cost advice

"Price-wise, VAST Data is not the cheapest, not the most expensive one."

"We acquired VAST Data as a one-time, capital purchase."
