Vendor business manager at TD SYNNEX BRASIL

AI projects have gained momentum as our team has built a strong pipeline for data‑intensive workloads

The best features Everpure FlashBlade offers, which stand out to both me and our customers, are its exceptional performance for AI and analytics workloads, its ability to scale seamlessly, its unified file and object storage architecture, and simplicity of management. Customers also value the fast backup and recovery capabilities, which are critical for cyber resiliency strategies. One of the challenges we face in Brazil is the price point. Everpure FlashBlade is a premium solution, and for many customers, the initial investment can be difficult to justify unless they have very demanding workloads such as AI, large-scale analytics, high performance, or cyber recovery. Because of this, our focus is on identifying customers where the business value and performance benefits clearly outweigh the cost. Since we have not yet deployed Everpure FlashBlade in production with a customer in Brazil with TDCX, I cannot speak from direct operational experience regarding its positive impact. However, Everpure FlashBlade has helped us engage in strategic conversations around AI, cyber resiliency, and modern data architectures. We have Everpure FlashBlade available in Brazil with TDCX for proof of concept activities, which allows customers to validate performance, scalability, and their real-world use cases before making an investment decision. This has been a significant asset in the presales and technology evangelization process and has helped customers understand the business value of Everpure FlashBlade. We have a proof of concept with a customer called M. Dias Branco in Lardas in Brazil. The project is in progress and we hope to close this sale this year.

Unified storage has simplified private cloud operations and delivers strong security and ROI

Regarding areas for improvement, I think Data Lens could be enhanced from Nutanix's side, but it has been a long time since I logged into that console, so I do not remember much. It is a SaaS-based offering on the Nutanix portal. It is not something you deploy on-premises; it is not on-prem access. You connect your cluster to the SaaS-based Nutanix and then access the Lens console. I need to check it since it has been almost two or three months since I logged in. Nutanix Enterprise AI actually needs to improve a lot if I compare it with any other product such as NVIDIA and other offerings in the market. Nutanix Enterprise AI still requires a lot of work. I did not check that in much detail technically, but whatever I thoroughly checked, it still lags behind in many features. When it comes to AI-related features, I think the ecosystem of Nutanix is not as big as NVIDIA because NVIDIA has its own inferencing system and model training platform such as NeMo, NeMoTron, and others. Nutanix does not have such things. It can be built using NVIDIA CUDA libraries, but what I saw when I was testing the product is that you can run NVIDIA NeMo and PyTorch and two other things, but as a software, Nutanix does not have an end-to-end platform. That is something Nutanix should focus on.

Backup storage has shrunk dramatically with deduplication but still needs stronger security options

The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.

Quotes from Members

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

Pros

"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."

"Speed and ease of use are the two most valuable features."

"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."

"The solution provides many controllers; more controllers lead to higher performance, and it is a unique feature provided by the product that other tools do not have."

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

"FlashBlade offers low latency, high throughput, and seamless scalability."

"The solution provides many controllers."

"We can capacity plan at a greater level than we used to."

More Everpure FlashBlade pros

"Customer support for Nutanix Unified Storage (NUS) is top-notch."

"What I appreciate most about Nutanix Unified Storage (NUS) is how easy it is to use and how simple it is to create new volumes and containers, and it's pretty quick."

"Nutanix Volumes is a perfectly stable product."

"Nutanix Files is a complete solution in the Telco Machine and offers a host of benefits, including easy management, upgrading, and analytics of new data."

"What I found most valuable in Nutanix Files Storage is its high availability and ability to scale out with many VMs."

"I would rate Nutanix Unified Storage a ten out of ten."

"My overall rating for Nutanix Unified Storage (NUS) would be nine out of ten, as I have no complaints."

"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."

More Nutanix Unified Storage (NUS) pros

"The dedupe and compression are pretty extreme. On disk, we're getting dedupe rates of up to 65 percent of data and compression of 34 percent. When you go to the cloud, it's more like 76 percent for dedupe and almost 50 percent for compression."

"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."

"This software solution can be installed on many different types of hardware, which makes it very flexible. We can run it on virtual machines or virtual servers, providing convenience for solutions of varying sizes, from small to large."

"Quest QoreStor definitely saved us money."

"The features we use for the data deduplication are nice because we're able to back up a much larger amount of data, yet it doesn't necessarily take up that much data on the devices."

"We need revisions and safe backup so that it could be held up in court, but deduplication and compression are the main features why we have Quest QoreStor. That's where it really shines. I use ZFS and XFS at home, and Quest QoreStor is even better."

"Quest QoreStor is very stable compared to our previous solution."

"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."

More QoreStor pros

Cons

"I would like to see more deduplication."

"We have one system at a customer's site that has had a lot of problems over the last year — I think maintenance was required over seven times before everything was corrected."

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

"I would also like to see better support for CIFS workloads."

"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."

"I would like to see more monitoring capability included in the next release of this solution."

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

More Everpure FlashBlade cons

"Allowing the use of the Gflag compromises the integrity of the Nutanix system and its established standards."

"The licensing terms are restrictive, as they go by terabyte cost."

"Since it's part of Prism, I might suggest integrating the management console into Prism instead of having a separate console; that's the only change I would recommend, and it's not a significant issue."

"The pricing could be improved."

"The GUI is not user-friendly for new users and has room for improvement."

"We have issues with software updates occasionally."

"In summary for improvements, I would say stay on the integration path, keep those integrations heavy, and let us use the software and technologies with everybody."

"It would be beneficial if there were a migration tool for the new way of syncing data for data protection."

More Nutanix Unified Storage (NUS) cons

"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."

"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something. So that when we don't do a backup, we want the QoreStor to stay offline. It would be a nice feature to have."

"They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved."

"There can be some kind of monitoring solutions to alert users to issues with the appliance or software, making it easy for customers to monitor their systems in the field."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial. After everything is set up and configured, there should be a way to export the configuration. In case something happens to the QoreStor server, and we need to reinstall and configure everything, being able to import the configuration would be helpful. This feature does not currently exist."

"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."

"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable. You have to have a connection to support to install."

"The setup of the software is definitely not the easiest thing in the world."

More QoreStor cons

Pricing and Cost Advice

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

"We used a reseller for the purchase."

"Licensing fees are paid yearly."

"Our customers have seen a reduction in TCO."

"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."

"The product is very expensive."

"The price of this solution could be made more affordable."

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

More Everpure FlashBlade pricing and cost advice

"Nutanix is very competitive."

"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."

"Its pricing is good to okay. It is not super inexpensive, but it is still competitive. Everything could always be lower."

"I hope that it will stay the way it is. We have seen the changes in VMware and what happened to them. I have heard that Nutanix will raise the prices, but I hope that they will not do that."

"The solution is highly-priced."

"The pricing is fair."

"The price of the license is expensive when comparing it to traditional storage."

"The solution's pricing is fair."

More Nutanix Unified Storage (NUS) pricing and cost advice

"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."

"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."

"Quest QoreStor's pricing is affordable. We evaluated Veeam, a well-known company for backup solutions, but found their pricing to be quite high. Veeam's price was almost double. For us, Quest QoreStor is very affordable."

"The pricing is good. It is competitive for a managed services provider. I like the ability to pay by the terabyte, allowing for an incremental cost that we and our customers can afford, so the solution grows with the customer."
