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.

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

"What I really like about this program, is that it is easy to use and easy to configurate."
"Overall stability is very good. It is a very stable solution."
"Technical support has been helpful and responsive."
"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 system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"It has benefited my organization because it has reduced time to insights."
"The latency is good."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"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."
"The management interface is great and you have handy access to several details about your file shares."
"We have virtually zero downtime with Nutanix. It updates itself, and we can easily move machines from one cluster to another."
"What I found to be the most valuable features were better performance and uptime."
"The most valuable feature is the storage density of the nodes. We went with the HP's low-density nodes."
"From an analytics perspective, the best aspect of Unified Storage is its locality. When you read data, you want to know that you're only reading data from the particular local storage node. It's also critical to access the data as quickly as possible from that. From a business perspective, the most important thing is ease of use. Having a combination of compute and storage makes it much easier to manage."
"We can utilize mixed storage block-sized objects and combine various databases within a unified interface."
"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."
"This has been one of the most reliable storage systems that I have ever used."
"The solution is useful for machine learning and scientific applications, including computer simulations."
 

Cons

"The tool's portfolio is minimal. It is expensive."
"There are some challenges with data encryption and reduction."
"The software layer has to improve."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"We need better data deduplication."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"There is room for improvement in the pricing of the product."
"Managing other storage infrastructure on Nutanix Files Storage is an area for improvement. In particular, I want to add other forms of storage from different vendors not currently in Nutanix Files Storage, to the file server, for better management."
"I would like to see the integration of artificial intelligence and machine learning technologies. That could definitely be a major breakthrough in providing a unified, seamless experience for end-users. It could reduce costs as well as human effort."
"Historically, it has been a hyper-converged infrastructure, so when you are looking to grow the solution, you need to scale the compute and storage. Having the ability to scale the storage independently would be a good improvement."
"The management is pretty clunky, in my opinion. It could be a little bit better."
"Pricing can always be better."
"Its licensing can be better. They can make it easier for us to scale our infrastructure."
"We have issues with software updates occasionally."
"I have heard that there have been latency problems."
"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 product is expensive."
"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."
"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."
"We pay approximately $50,000 USD per year in licensing fees."
"The support cost per array is about $20,000 a year for 24/7 support."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"Given its price, Pure is not the first option."
"The solution is highly-priced."
"Nutanix Unified Storage pricing is reasonable."
"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."
"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."
"It is not too high for what we are using."
"While the price may not be the most affordable, I believe it offers good value for the benefits it provides."
"Its pricing is good to okay. It is not super inexpensive, but it is still competitive. Everything could always be lower."
"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."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
