Featured Reviews

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.

Seamless management and exceptional performance facilitate efficient data handling
I have not faced significant problems or challenges with Dell PowerMax NVMe during this time, although one area for improvement is its user-friendliness, as it's a bit engineer-oriented. Specific knowledge and expertise are required to manage it properly, which some users might find a bit challenging, yet it's not a big deal for me. With user experience in mind, an improvement for Dell PowerMax NVMe could be clearer total capacity measurements from snapshots and clones, which should be more visible for better planning. Additionally, a template script from PowerMax could assist customers in easily integrating their API-interconnected systems without needing extensive knowledge. To improve regarding scripts, I recommend that if a customer wants to automate snapshots from other systems, Dell can assist by providing plug-and-play integrated templates that allow customers to drag, drop, modify, and connect with any target system for generating snapshots without logging into the storage directly.
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.

Quotes from Members

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

Pros

"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."
"The most valuable features of this solution are its ease of use and performance."
"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 most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"Technical support has been helpful and responsive."
"The solution is very straightforward to set up."
"The most valuable feature of this solution is reliability."
"The solution is stable. I would rate it ten out of ten."
"The features I find most valuable about Dell PowerMax are its stability and flexibility."
"The uptime is the most valuable feature."
"PowerMax is a compact high-performance appliance. It is one of the best devices in terms of performance specs. It includes an NVMe All-Flash Array."
"The upgradability and extendibility for the size of the storage unit are noteworthy."
"Dell support for Dell PowerMax is exceptional, rating a perfect 10 out of 10."
"It is a true, stable product."
"The most valuable feature of Dell PowerMax is its reliability."
"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 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."
"It's a centralized place for management. With all our virtual machines and Kubernetes in there, it's a single place to manage all of our resources, instead of having to jump around to different places."
"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."
"I like its interface. It is very interactive and simple to use."
"I find that Nutanix’s resilience is the most valuable because it is a feature that is not found in other technologies."
"We can utilize mixed storage block-sized objects and combine various databases within a unified interface."
"My opinion is that this solution has very good stability."
 

Cons

"It is on the expensive side."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"In the future, I would like to see integration with enterprise backup systems."
"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 UI for this solution needs to be improved."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"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."
"Dell needs to offer more midrange storage options with enterprise-class features similar to the PowerMAX."
"The solution should integrate better with OpenShift and Kubernetes architecture."
"Support of the product can be slow and an administrative challenge: planning, scheduling, and overseeing data center access for a Dell EMC rep. One improvement could be to enable a self-maintenance option. The requirements that we go through to get Dell EMC onsite to replace failed drives, power supplies, and other small redundant parts can be unnecessarily complex. If simplified, they could send us the parts, then we could replace them much faster, more easily, and truly within the SLA parameters."
"I would like to see more security features and improvements in the platform's ease of management."
"Remove the need for physical or hardwired virtual servers to run consistency groups, instead make the expensive array controllers handle that."
"The tool is costly compared to other similar products. The product's pricing needs to be improved. I would like the product to include the replication feature in its future releases."
"Dell PowerMax needs more connectivity options for projects that require separate web access."
"The tool needs to improve its performance. Today's applications are demanding a response rate of one millisecond or below. The product should also look into AI integration."
"Allowing the use of the Gflag compromises the integrity of the Nutanix system and its established standards."
"If they can add an integrated DLP feature, it would be great."
"From the speed perspective of Nutanix Unified Storage (NUS), it could enhance some features to make it the best storage solution in the market."
"The graphical user interfaces could benefit from more attention to detail."
"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."
"The dashboard can have more details and be more useful."
"The dashboard could be more customizable"
"The solution is very expensive."
 

Pricing and Cost Advice

"Given its price, Pure is not the first option."
"Our licensing fees are $500,000+ USD."
"We pay approximately $50,000 USD per year in licensing fees."
"With VMware, we pay $300,000 annually."
"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."
"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."
"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 cost has room for improvement."
"The price is really high."
"The price is on the market. It's not inexpensive, but it's available on the market."
"From reclaiming data center space which is so tightly constrained these days, it will pay for itself in a short amount of time, which is fantastic. Anything we can do to get more out of our current physical data center space helps us a ton, and PowerMax has helped enable that."
"One area for improvement, one that everybody always comes to, is price... it's still quite expensive to purchase these big arrays... For us, the pricing doesn't make Dell EMC uncompetitive."
"Support pricing is very high. Our support contract is about to expire and Dell EMC provided us with an extremely high renewal quote. It was four times more than the support contract for our previous EMC VNX solution."
"Our costs for the product are three million."
"Our costs are on a yearly basis."
"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 is highly-priced."
"While the price may not be the most affordable, I believe it offers good value for the benefits it provides."
"From what I hear from the management, Nutanix Unified Storage has comparatively decent pricing."
"It is very good. It is much more competitive than a dedicated storage platform."
"The price of the license is expensive when comparing it to traditional storage."
"The licensing currently works based on a software license. If we have files, volumes, and other licenses combined, that would be more valuable. I don't want to go for a separate license for files and a separate license for volumes. We have unified storage, so the licensing should also be unified. That would be helpful."
"Nutanix Unified Storage is competitively priced. There aren't any competitors that can do much better for the same price."
