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

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The most valuable feature of this solution is its ease of use."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The high availability of the product is the most valuable feature."
"The solution is scalable."
"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."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"The features that I found most valuable are SnapMirror and SnapVault; these provide DR and backup for data redundancy."
"Technical support is good."
"The most valuable feature of NetApp AFF is the reputation of the company."
"NetApp AFF has helped to simplify our clients' infrastructure while still getting very high performance for their business-critical applications. One of our customers uses the vSAN environment in the release, then they use NFS for their VMware VCF environment and TKG environment. In this case, when they move to NetApp for the TKG and the VM infrastructures, they use AFF for block, CIFS, and NFS. It provides a single storage with NFS, block, and CIFS with deduplication, team provisioning, and compression. Everything is in there, which makes it very good to use."
"We had some customers who were running virtualization workloads on classical spinning disks. We implemented an AFF system, and they got a huge performance boost out of it because the latency of the SSDs is simply much lower. Actually, most customers benefit from the improved latency and performance from the AFF systems."
"Its efficiency and scalability are the most valuable features."
"AFF has opened our eyes in a different light of how storage value works. In the past, we looked at it more as just a container where we could just dump our customer dBms and let the customers use it in terms of efficiency. Today, to be able to replicate that data to a different location, use that data to recover your environment or be able to have the flexibility with the solution and data. These are things which piqued our interest. It's something that we're willing to provide as a solution to our customers."
"I think that the DR applications are the most valuable, including Snapshots and SnapMirror."
"Nutanix Objects is reliable."
"For somebody like me who grew up building what others call three-tier and I call traditional architecture, the valuable thing is that you can now buy it. You can have new deployments and infrastructure up and running with very little infrastructure behind it."
"The solution is very easy to manage."
"Nutanix Unified Storage is easy to use. New employees are able to come up to speed fairly quickly with regard to the day-to-day administration processes."
"The initial setup is pretty straightforward. With a few clicks, you can stand up your storage. It reduces the overall life cycle of deployment within the ecosystem."
"From an analytics perspective, the best aspect of Unified Storage is its locality. When you read data, you want to know that you're only reading data from the particular local storage node. It's also critical to access the data as quickly as possible from that. From a business perspective, the most important thing is ease of use. Having a combination of compute and storage makes it much easier to manage."
"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 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."
 

Cons

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"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."
"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's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"NetApp should have a local presence in Pakistan."
"ZAPI is kind of difficult to use. You know, it's SOAP-like, it's not really SOAP. I would like to see it more of a REST-based JSON, instead of XML."
"There are some bugs with the solution which need to be fixed."
"I think adding more features to make it more cloud enabled will help us with cloud tiering and simplify the whole cloud operations when it's integrating with our on-prem AFF products. That is one area where we would like to see more improvements from NetApp."
"It would be helpful if the compatibility matrix was a bit better."
"NetApp AFF is a highly expensive solution, and its pricing should be reduced."
"We don't have many issues related to the appliance itself. In terms of the OS, we do get some hiccups here and there."
"FC and ATTO bridges are still needed for cross datacenter replication."
"The graphical user interfaces could benefit from more attention to detail."
"The graphical user interface could provide more detail. It would be nice if we could click on the service and get some expanded definitions of them. When hiring new people, it's difficult to teach them how everything works, but if they can access everything, they can teach themselves."
"The documentation on the support site needs to be improved."
"The product needs to work a bit more on its ransomware detection capabilities."
"We have some problems with Nutanix Unified Storage's support because they asked us to change our hardware."
"There are still some gaps in the solution's synchronization that could be improved."
"There is no tagging concept in Nutanix Unified Storage where you can tag the servers."
"Nutanix needs to improve their cybersecurity options at the storage level."
 

Pricing and Cost Advice

"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 support cost per array is about $20,000 a year for 24/7 support."
"The licensing is on a yearly basis."
"As far as the licensing costs, everything is included in the license."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"Our licensing fees are $500,000+ USD."
"Comparing this solution to others it may seem expensive, but the price to performance for NetApp is greater."
"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."
"I would like it to be a lot less expensive, but it's been a very good solution for us."
"One of the reasons we like this solution is that all of the features are included with the one license."
"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."
"It's expensive. it's in the hundreds of thousands. It's beneficial, but at times, I feel compared to other vendors, we are paying a premium for the licensing that other vendors include."
"It definitely reduces costs because it simply takes less power to run these systems. While the SSDs don't take power, they are in general very big right now. So, the running cost has decreased for a lot of our customers."
"Our total cost of ownership (TCO) has decreased by 40 percent."
"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."
"Nutanix Unified Storage pricing is reasonable."
"The solution’s pricing could be cheaper."
"It is very good. It is much more competitive than a dedicated storage platform."
"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."
"The solution is highly-priced."
"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."
"Nutanix is priced a bit higher than some of its competitors. A lot of Chinese companies like Huawei are entering the Saudi Arabian market trying to provide similar solutions for a lower price. It offers a good value, especially the support. Nutanix has a highly competent team. The after-sales support is excellent."

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…
