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.
Moin-Shah - PeerSpot reviewer
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 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."
"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."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"It has good, reliable, fast storage."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"What I really like about this program, is that it is easy to use and easy to configurate."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The most valuable features of this solution are its ease of use and performance."
"It's faster and more resilient."
"The most valuable feature of Dell PowerMax NVMe is its replication feature."
"The SRDF site-to-site replication for the volumes is the most important feature for us. That enables us to do site recovery and replication for our VMware infrastructure."
"We are using the solution's application and snapshot feature."
"We removed the need to observe whether we ran into issues with the performance of disks or number of IOPS. Previously, our Oracle Database would throw us performance errors. Now, with PowerMax, everything runs smoothly."
"Performance and management aspects are satisfactory."
"The solution's snapshot capabilities and replication are very good features. Snapshots are allowing us to quickly build analytical models directly from production data. This gives us amazing insights into market trends and allows us to build more effective trading algorithms. Replication offers us unparalleled levels of resilience."
"The product is very fast and reliable."
"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."
"It is unified. This is the best thing that Nutanix gave to the world. You can do everything from one point."
"I would recommend Nutanix Unified Storage. It's easy to use, and they are the best when it comes to storage services."
"Nutanix Unified Storage is a stable solution that provides good storage and efficiency."
"The Nutanix block files are the most valuable feature."
"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 solution's most valuable feature is the Prism Central centralized management console."
"Nutanix support deserves a rating of nine out of ten."
 

Cons

"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."
"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."
"They could add more support for file storage and different types of storage."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"Adding some functions to the product would be beneficial."
"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."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"The tool's pricing is higher than competitors."
"Dell PowerMax NVMe needs to increase storage and improve scalability."
"The one area for improvement in Dell PowerMax NVMe would be to align the features of the on-premises version with those available in the cloud, as this would provide added value and flexibility."
"There is also room for improvement in the PowerMax architecture and hardware itself. They should design the PowerMax on the basis of PCIe 4.0. I would like to see the possibility of an NVMe drive that operates on PCIe 4.0 and not PCIe 3.0."
"I would like a more informative CloudIQ for iOS. What you can see via the web UI significantly differs from what you can see via the web application."
"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."
"If you go to Pure or you go to NetApp, they deliver in one month. If you go to Dell or HP, they will take up to six months for delivery. This is not a business model for today."
"I hear from people on my team that they would like improved reporting. While there are some decent tools for doing reporting, they would like to see a lot more built-in functionality. This way when they are logged into the interface everyday doing basic management tasks, they could also see some statistics on what is their storage pool usage and will be their projected usage with their current data growth. They want to be able to see more detailed stats on how they are using the system and have forecasting."
"Although they call it unified storage where you have SAN and NAS, with a NAS implementation on top of a SAN, the NAS implementation is a little complicated and clumsy. As SAN, as block storage, it is very powerful... If they could provide a very good NAS implementation, it would be better, so that customers don't have to look for other simple solutions for NAS."
"Security is an area for improvement. When there are vulnerabilities, there needs to be a faster approval process. The solution needs to automatically target the vulnerabilities and not waste too much time."
"The solution's monitoring and security features could be improved."
"Allowing the use of the Gflag compromises the integrity of the Nutanix system and its established standards."
"A centralized file share permissions console might be useful for Nutanix Unified Storage (NUS). Getting in and directly managing permissions instead of using the snap-in from Windows itself might be something to consider, but that's a small thing."
"I really want some AI or even basic AI to be included in the Nutanix Unified Storage (NUS) license."
"There are still some gaps in the solution's synchronization that could be improved."
"It functions as intended. We don't have any real requests or improvements. We're primarily focused on protecting our data. However, we use Varonis, so it would be nice to have better integration with that."
"The solution should include more protocols to access data."
 

Pricing and Cost Advice

"We pay approximately $50,000 USD per year in licensing fees."
"The licensing is on a yearly basis."
"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."
"Our licensing fees are $500,000+ USD."
"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."
"With VMware, we pay $300,000 annually."
"Given its price, Pure is not the first option."
"The labor savings and support have been significant. If we're talking 100 hours of labor every three months, that is 100 hours of a database engineer costs. There are performance latency numbers as well as costs associated with recovering data that gets lost, and this system doesn't lose data. You can look at numbers that go around the cost of downtime, if data is not available. This system doesn't go down. Everyone's ROI is going to be unique, but the dependability and performance of the system combined with its ease of operation will definitely save businesses of all sizes money."
"The pricing is competitive. I would rate the pricing of the solution a six out of ten."
"The price is really high."
"In terms of price-performance, it beat out other competitors when we were taking a look and comparing it to the market. That was one of the biggest driving points for us."
"The cost of the solution is quite noticeable, but it provides a good fit regarding the price of the hardware and all of the required licenses."
"Dell offers various pricing models, including a pay-as-you-go option where storage is provided without upfront charges, billing only for used capacity. As a 360° partner, significant discounts are available."
"The price is on the market. It's not inexpensive, but it's available on the market."
"The cost is expensive. While VMAX now has good pricing, PowerMax is a little expensive."
"I am not the one who makes the calls, but it seems to me that it was very competitive. Other solutions would have required dedicated hardware, so an additional CapEx has to be put in place. In that sense, it was definitely a more competitive option to go with Nutanix Files."
"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."
"The solution's pricing is better compared to other products."
"It is very good. It is much more competitive than a dedicated storage platform."
"Nutanix offers different pricing options, including Ultimate and Ultimate Pro."
"The product is pricey."
"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."
"I assume Nutanix Unified Storage (NUS) has helped reduce our total cost of ownership."
