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.
Anna Sofo - PeerSpot reviewer
Since switching, our clients have reported improved performance and reduced latency
I like NetApp AFF's deduplication. The solution's AutoSupport feature is efficient and effective because customers are notified of potential issues before they experience problems with NetApp. The support is sold based on metro clusters, so they guarantee the client's business continuity. NetApp has an Active IQ app that allows you to get information on your smartphone.

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

"What I really like about this program, is that it is easy to use and easy to configurate."
"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."
"Everything, especially the VMs inside, is pretty fast."
"I appreciate the performance."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"It has good, reliable, fast storage."
"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."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"This solution makes everything a lot faster. The time to move data around, boot and migrate VMs is much faster."
"The most important features are the IOPS and the ease of the ONTAP manageability."
"The features that I found most valuable are SnapMirror and SnapVault; these provide DR and backup for data redundancy."
"We are spending less time putting out fires, so there's a tangible benefit right there."
"Speed, reliability, ease of use are the most valuable features."
"Replication would be one of the most valuable features."
"We have a unified storage to access the file and NAS. We can do all the things in the same solution. We do not need any other product or storage mix."
"One of the main features that differentiate AFF from the FAS products, or some other technologies used, is the footprint of these arrays are significantly smaller than the traditional ones. Also, the performance that you get to these new arrays is really significant. You can see a huge difference there. By switching to it, we can achieve more storage performance and efficiency as well as in the long run lower down some of the TCOs due to reducing the footprint."
"The solution is easy to use, share, and manage."
"The integration with Prism Central makes it a lot easier to manage, so we just have a single pane of glass location that we can go to. We do not have a separate admin console or anything that we have to use."
"The reliability and availability are the most valuable features. Reliability is important because it can run my workloads. I need to be able to take advantage of the VMs that are executing on the storage. It has to be reliable. It's also important to have the storage available for scaling VMs on demand."
"It gives more security that the data isn't going to get lost."
"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."
"The product's initial setup phase was simple."
"Nutanix Unified Storage is a stable solution that provides good storage and efficiency."
"I like its interface. It is very interactive and simple to use."
 

Cons

"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"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."
"There are some challenges with data encryption and reduction."
"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."
"I'd like to see the product implement active replication for vehicles such as VMware."
"In the future, I would like to see integration with enterprise backup systems."
"I don't work on the technical side of things, so it's hard for me to highlight areas of improvement, but maybe the price could be a little better."
"I've had a few cases where support wasn't able to answer the question or they took quite a while."
"The upgrade process could be a lot quicker, but it's still good as it is. The failovers and things like that are harder than expected."
"In terms of improvements, they could have a couple more things that are usually done through the command line."
"When it comes to the cloud, they might need to improve in terms of making it clear why someone would use a NetApp solution over cloud-made storage."
"It used to give us the volume where LANs should be placed when we created a LAN in the older version. However, in the newer version of ONTAP, it does not give where to place the LAN in the volume. So, that liberty has been taken away. If that was there again, it would be very good."
"The admin tools and the integration with other products and clouds can be improved. It should also be easier to identify and troubleshoot problems in this solution. It takes a long time, and it should be improved."
"AFF could introduce different subscriptions on the platform."
"It could be more user-friendly."
"We have issues with software updates occasionally."
"We have some problems with Nutanix Unified Storage's support because they asked us to change our hardware."
"Its interface is very simplistic. It is a good thing for people because of the ease of use, but at times, I find it too simplistic. It is hard to find advanced options. They should eventually expand it and provide additional drop-down lists or menus with advanced feature sets."
"Perhaps when it comes to deploying NUS virtual machines on top of CVMs, it should not be necessary for it to be in all of them or they should require fewer resources on the servers."
"Customer service is more difficult to call and they do not responding as much as, for example, DataCore. It's not the same level of satisfaction compared to DataCore. Responses could be faster."
"The biggest thing for me, which is a pet peeve of mine, is the integration with the hardware platforms."
"The feature request I have is for the consistent improvement of how user account permissions are assigned in Nutanix Unified Storage."
 

Pricing and Cost Advice

"The support cost per array is about $20,000 a year for 24/7 support."
"The product is expensive."
"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."
"With VMware, we pay $300,000 annually."
"Our licensing fees are $500,000+ USD."
"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."
"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."
"With other options, you need to buy a couple of different products to achieve the same outcome."
"The solution is moderately priced."
"Always consider whether you can afford the solution."
"We benefited from implementing all-flash by reducing our data center footprint. We took it from 30 racks to just over five. This is one of the biggest savings for us."
"We have been able to utilize and leverage equipment which was purchased a decade ago up until this past year. So, we were running disk shells for 13 years and all we were doing was upgrading the filings and controllers, and using the same disk shells. Therefore, we were able to do something where we didn't have to invest that much. Recently, we had to upgrade all our disk shells, but it was a lot less because the technology had changed a lot since those times. It is faster now, and we have SSDs. We have larger drives that are 4TBs and 6TBs. Everything can condense so we are saving disk shell space and rack space. We are paying less now than we did at that time"
"Comparing this solution to others it may seem expensive, but the price to performance for NetApp is greater."
"NetApp is getting too expensive."
"Look at the different options that NetApp offers. Look for a model and option which fits your needs correctly. Don't buy a low-end product for a high-end job."
"I find Nutanix Files Storage competitively priced, even its feature set. Its price is seven out of ten."
"The pricing is a bit too high."
"I'm happy with the cost and licensing because I don't have big volumes."
"The product is pricey."
"Its pricing is good to okay. It is not super inexpensive, but it is still competitive. Everything could always be lower."
"Nutanix Unified Storage isn't expensive."
"The cost of Nutanix Unified Storage can be prohibitive for some small and medium-sized businesses, making it challenging for them to adopt the product."
"Nutanix Unified Storage pricing is reasonable."

NetApp vs. XtremIO
Is there another storage platform as feature rich as NetApp FAS? I think it is fair to say that NetApp FAS running Clustered Data ONTAP is a very feature rich platform – the move to the clustered version of ONTAP has brought many next-generation features including Scale-out and Non-disruptive…
