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.
Hassan_Zaki - PeerSpot reviewer
Integrated AI and clustering enhance storage operations effectively
I promote and recommend Dell PowerStore for all workloads to my clients and customers. Most of my customers have one appliance per site. Approximately 80% of my customers have Dell PowerStore implemented in their data centers. We always use CLS as another Dell solution for cybersecurity and data security. The CLS is integrated with the Data Domain, PowerProtect Data Domain, not with Dell PowerStore. Windows, Linux, and some customers use Red Hat or SUSE. We have many operating systems working with Dell PowerStore in the same environments and data centers. CloudIQ and Storage IQ are used by some customers, but Apex AIOps has not been widely adopted yet. Dell PowerStore has integration with VMware and Kubernetes. Most workloads work fine and have very good integration with Dell PowerStore, except for one or two specific workloads in the market. On a scale of one to ten, I rate Dell PowerStore a nine.
Amarnath Charugundla - PeerSpot reviewer
Unified management and cost-effectiveness lead to positive experiences and future savings
Improvement is necessary wherein the memory or storage should not breach 90%, because if breached, it becomes unmanageable. We have to set alerts or CPU triggering for 95% for the first warning. Other activities on nodes or file systems should be properly maintained. We must monitor the dashboard for P1, P2 alerts in the Nutanix Unified Storage (NUS) file share system including SMB, NFS, objects, and blocks. Attention should be maintained for any alerts such as CPU, memory, and RAM alerts, as exceeding these creates issues within teams. If triggered to 95% and forgotten, it crosses the SLA breach, causing disturbances to application, web, and platform teams. Continuous monitoring on the Nutanix dashboard is essential. Even a highly experienced person in Nutanix Unified Storage (NUS) cannot provide a 10 rating out of 10 because it is a vast system. I would rate it eight from my perspective.

Quotes from Members

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

Pros

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The solution is very straightforward to set up."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"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."
"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."
"The solution uses newer technology for deduplication and compression."
"I appreciate the performance."
"Dell EMC PowerStore is scalable."
"In the five months we've been running Dell PowerStore, it's been 100% uptime with no issues at all, so it's been excellent."
"The most valuable feature of Dell PowerStore is the metro cluster because we have two data centers and high availability."
"The return on investment since switching to Dell PowerStore has been really good."
"Currently, the features of replication and deduplication have been very important to us."
"The most valuable feature is the unwavering performance."
"We find NAS to be the most impactful feature of Dell PowerStore. The compression and deduplication technology is very important and essential, and this was one of the reasons that we decided to go with Dell PowerStore."
"My company found the tool to be really easy to use, expand, and manage."
"I strongly recommend Nutanix Unified Storage (NUS) to all users."
"The most valuable feature is the unified dashboard, as it allows us to easily observe everything from a single location."
"The reliability and stability of Nutanix Unified Storage (NUS) are very good, and after almost four or five years of usage, we haven't encountered significant issues."
"It is very scalable."
"It scales well. I started with two or three servers, and I have added almost 20."
"One of the main features of Nutanix Unified Storage (NUS) that I find most valuable is the flexibility and scalability of it, as well as the ability to perform replication for our Disaster Recovery environment."
"We had three racks full of storage and now it is just half a rack."
"Offers high performance, full control, and strong security for mission-critical workloads."
 

Cons

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"I would like to see replication and DR features in the next release of this solution."
"In the future, I would like to see integration with enterprise backup systems."
"Maybe the price can be reduced since the solution is very expensive."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"There are some challenges with data encryption and reduction."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"I have realized nothing exemplary from using Dell PowerStore, except hat the user interface is clunky, and we've had issues with that."
"The design needs to be something similar to Pure Storage. It would be beneficial if there are different color or lighting options for different product casings. Different colors are helpful when working in the data center server room."
"We would consider this solution if the pricing is competitive with other options, as it offers a very good solution. However, the current price is slightly higher than the competition."
"We used to be able to see the metrics for our customers. On Compellent, we could look up that customer and see all the metrics. That is not allowed for us now. We cannot do that anymore. I have to be explicitly allowed by the customer to do that, and some companies' security does not allow that."
"If I could improve the product in any way, I would add features that make it look nicer compared to the DisplayPort."
"The interface of Dell PowerStore reminds me of the Cisco mentality where it's just boxes moving around as you're clicking; it's not easy to understand what you're trying to do, and you have to have solid documentation to navigate the system and make changes to ensure you're not jeopardizing your system as you present and remove storage and expand LUNs."
"You cannot delegate permissions."
"Dell PowerStore is a very expensive storage solution. That said, the speed for recovering information is amazing. I would make the product cheaper. The discounts from Dell to South America are not sufficient because we need better pricing. The discounts for small PowerStores are not enough to close deals since I'm a distributor. As both a user and seller, it's challenging to sell Dell PowerStore to the channel or final customers because we don't have enough discount from Dell."
"We have some problems with Nutanix Unified Storage's support because they asked us to change our hardware."
"The pricing could be improved."
"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."
"There is potential to push this product more since it's not common in the market. They could increase their marketing efforts."
"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."
"For future updates, I think Nutanix Unified Storage (NUS) should look at features similar to what ONTAP of NetApp is doing, such as tiering to the public cloud."
"Nutanix Unified Storage (NUS) can be improved in the area of big data workloads, as we still need to improve performance there."
"Nutanix Unified Storage (NUS) needs improvement in compatibility with Windows solutions."
 

Pricing and Cost Advice

"As far as the licensing costs, everything is included in the license."
"The product is expensive."
"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."
"With VMware, we pay $300,000 annually."
"Our licensing fees are $500,000+ USD."
"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."
"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."
"Dell PowerStore charges for the hardware warranty every three years. The price will depend on the storage model or how much hardware it has."
"Dealing with the licensing part of the product is very simple, especially considering the fact that we don't have many licenses associated with the tool."
"The price is high compared to the Tunisian market."
"PowerStore's pricing is reasonable."
"It is easy to work with Dell from the licensing perspective."
"The price of Dell EMC PowerStore could be better, it is a bit expensive."
"The solution’s pricing is always too high."
"The pricing structure and licensing model of Dell PowerStore are pretty decent. It's pretty competitive."
"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."
"While the price may not be the most affordable, I believe it offers good value for the benefits it provides."
"It's definitely a lot cheaper than buying a new EMC array. We bought a five-year commitment on all the hardware and software. I don't know what the cost was back then, but I do remember it was cheaper."
"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."
"The price of the license is expensive when comparing it to traditional storage."
"It is very good. It is much more competitive than a dedicated storage platform."
"In the manufacturing industry, we operate under very lean principles where costs are heavily scrutinized. There was some initial hesitation, but the performance we've experienced since switching to the Nutanix platform, along with the peace of mind from having confidence in our platform to not give us issues that keep us up at night, has smoothed over much of that scrutiny."
"In my opinion, the product is fairly priced."
