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.

Offers good performance and
Once, I've been in a program, but they stopped supporting protocols like HTTP, STP, and that kind of stuff. All of the DIP supports at the beginning were kind of support when it was just Python and just five storage. And it happened a few times that the customer required the STP and HTTP protocol for storage. And I was surprised I couldn't do it anymore with NetApp. So, it would be beneficial for them to support both kinds of protocols. The only little black points that I would put on top of NetApp FAS Series. There is room for improvement in deployment and configuration processes. The thing with ONTAP is that we have a lot of layers, from the raw disks to the volumes we present to servers and configure. There are quite a lot of things to configure. Probably NetApp should ease the way to install that. In NetApp products, such as ONTAP and FAS, a solid understanding of storage is still necessary to handle configurations in larger systems. It's not the same with Pure Storage or Huawei. Even someone less familiar with storage could manage it, making it more accessible.

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

"The high availability of the product is the most valuable feature."
"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."
"The most valuable feature of this solution is reliability."
"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."
"Everything, especially the VMs inside, is pretty fast."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"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."
"It has benefited my organization because it has reduced time to insights."
"I have found all the features useful in NetApp FAS Series."
"The storage efficiency provided a maximum savings in our storage utilization."
"Compression of the backup Oracle by RMAN on NFS saves space 5:1."
"The solution is stable."
"It is good to have a unified storage where you can have block and file level protocols."
"The most valuable features are the NAS features and NetApp's excellent support."
"The most valuable feature is SnapMirror."
"Snapshot, deduplication, and compression features are valuable."
"I rate the overall solution ten out of ten."
"Redundancy and availability are valuable. We have several nodes, so it stays up, and there is redundancy. Then there is availability."
"Nutanix technical support is excellent, with swift responses based on priority."
"Offers high performance, full control, and strong security for mission-critical workloads."
"My company has benefitted from Nutanix Unified Storage because we have everything in a centralized place. With Prism Central, we can go to the console files and do what we have to do."
"The feature I like most about Nutanix Unified Storage (NUS) is the ability to optimize storage spaces."
"Nutanix Unified Storage is very stable."
"The solution is very easy to manage."
 

Cons

"We would like to see VNC integration or be able to use Pure Storage with VNC."
"There are some challenges with data encryption and reduction."
"In the future, I would like to see integration with enterprise backup systems."
"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."
"In terms of what needs improvement, the dashboard and management could be simplified."
"It is on the expensive side."
"The software layer has to improve."
"The UI for this solution needs to be improved."
"One area that needs improvement is the hyper-converged solution. Although NetApp has a solution, compared to Nutanix, it falls short."
"The solution could do more than just data."
"They should add new features to the product."
"Regarding the stability of NetApp FAS Series, I would rate it seven or seven point five because there are frequent panic messages."
"When we were going through all the MFA hardening and the anti-ransomware setup, I gave some feedback to our executive. The MFA process for getting that set up on the AFF systems was cumbersome compared to some of our other systems."
"Needs to ​add wizards for newer, inexperienced users."
"The high cost of the product is an area of concern, so from an improvement perspective, the tool needs to be made cheaper."
"There is no NetApp infrastructure set up here in Greece."
"Nutanix Unified Storage (NUS) sits in a good place for us. The biggest improvement would be to make it more cost-effective from a storage node and storage perspective, so that the solution isn't such a question when it comes to cost-prohibitiveness versus potentially other vendors."
"The pricing can be quite high."
"There should be more automation. Going deeper, I would appreciate seeing out-of-the-box automation for storage provisioning and maybe some more customer-facing, web portal-type or API functionality to Jira or ServiceNow."
"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."
"What's missing in Nutanix Files Storage is the support for multiple intranets or VLANs on the same file from different networks and network devices."
"The graphical user interfaces could benefit from more attention to detail."
"There are some processes, like if I like to change the data storage to another place, I have to use CLI, and I don't like it since I believe that it could have been simpler in GUI."
"Another aspect that needs improvement is continuous protection against security threats such as ransomware and potential data leakage."
 

Pricing and Cost Advice

"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."
"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."
"As far as the licensing costs, everything is included in the license."
"The support cost per array is about $20,000 a year for 24/7 support."
"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 product is expensive."
"We pay approximately $50,000 USD per year in licensing fees."
"The licensing is on a yearly basis."
"In general, I find NetApp to be very expensive. That's the main issue I have with them. So it's a drawback in terms of pricing."
"Cost effective storage for all performance levels (including all-flash)."
"The only area that could be improved is to lower prices for their All Flash FAS."
"We purchased it for four years, and it wasn't expensive. It was reasonable. Every company has a different agreement with NetApp. We got everything we wanted with all the bells and whistles and all the features and functionalities."
"The tool is expensive."
"It is a moderately low-priced platform."
"The price it not low, but comparing features to other vendors, the price can be balanced."
"I would rate the pricing a seven out of ten, with ten being expensive. We pay a one-time purchase price."
"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."
"It is competitive with other vendors, but you get more for your dollars. It is fairly priced, but not cheap."
"The pricing is a bit too high."
"Nutanix Unified Storage was cheaper than other solutions we evaluated."
"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."
"The product is pricey."
"From what I hear from the management, Nutanix Unified Storage has comparatively decent pricing."
"It is not too high for what we are using."
