Centralized management and high resiliency streamline data storage with immediate benefits and scalability

The most effective features of Nutanix Unified Storage (NUS) for us are about making multiple copies of our data across hardware nodes, ensuring that if there is a hardware failure, we still don't lose our data, which I think is the most important. Also, they have a file solution that is good for file shares, and that is of value to us. The switch from solutions such as IBM to Nutanix Unified Storage (NUS) was driven by the need for different skill sets for a separate storage team and separate compute team. Maintaining these old devices was getting prohibitively high, so consolidating everything onto Nutanix Unified Storage (NUS) made sense and allowed one set of Nutanix engineers to manage the entire estate.

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.

Quotes from Members

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

Pros

"The benefit that our clients see is the security of the whole Nutanix platform where they have simplified usage."

"What I like most about Nutanix Files Storage is the way it makes copies of the data. The solution also has high availability, which is excellent. Another valuable feature of Nutanix Files Storage is self-service, so users won't have to depend on the IT team much."

"We appreciate how Nutanix Unified Storage (NUS) performs very well. We appreciate being able to have the duplication of the data to a secondary location."

"The life cycle managers of the PCMs are very impressive, and I like them. They make our lives easy when managing patches and security updates when they come in. A life cycle manager helps to consolidate different vendors."

"The performance of Nutanix Unified Storage (NUS) increased almost 50%."

"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 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."

"It scales well. I started with two or three servers, and I have added almost 20."

More Nutanix Unified Storage (NUS) pros

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

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very 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."

"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."

"One of the best features is the support, which is excellent."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"It has benefited my organization because it has reduced time to insights."

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

Cons

"The licensing terms are restrictive, as they go by terabyte cost."

"The dashboard can have more details and be more useful."

"Nutanix Unified Storage (NUS) sits in a good place for us. The biggest improvement would be to make it more cost-effective from a storage node and storage perspective, so that the solution isn't such a question when it comes to cost-prohibitiveness versus potentially other vendors."

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

"Nutanix could improve the ability to track user actions, such as identifying who deleted a folder."

"The interface could be improved."

"The documentation on the support site needs to be improved."

"Allowing the use of the Gflag compromises the integrity of the Nutanix system and its established standards."

More Nutanix Unified Storage (NUS) cons

"We need better data deduplication."

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

"In the next release, I would like to see real-time analytics for further insight into consumption models."

"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."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

"They could add more support for file storage and different types of storage."

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

Pricing and Cost Advice

"It is very good. It is much more competitive than a dedicated storage platform."

"Nutanix offers different pricing options, including Ultimate and Ultimate Pro."

"From what I hear from the management, Nutanix Unified Storage has comparatively decent pricing."

"While the price may not be the most affordable, I believe it offers good value for the benefits it provides."

"Licensing-wise, I have no complaints. Their license is pretty simple and easy. It gives us everything we need, so I have no complaints about licensing."

"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."

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

More Nutanix Unified Storage (NUS) pricing and cost advice

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

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."

"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."

"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 support cost per array is about $20,000 a year for 24/7 support."

"We pay approximately $50,000 USD per year in licensing fees."

"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."
