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

"It performs well and it is also very fast."

"The performance of FlashBlade is excellent. It does not necessarily leverage the SOS API that some of the newer products leverage, but I found its speed pretty much on par and comparable. It is fast, and it does what it is supposed to do."

"The most valuable features are the Metro clustering, and disaster recovery."

"The solution is very easy to manage."

"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."

"It's very easy-to-use."

"We haven't had any issues with it, it's easy to use, and the speed is incredible."

"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

More Everpure FlashBlade pros

"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."

"Since I started working with Nutanix, the only consistent thing I can identify as key is simplicity."

"The availability of the environment is incredible, and with Prism Central, you're able to diagnose and go over issues quickly."

"We have been able to save local disk space by using Data Lens. We upload 18 GB to the cloud and are able to save 20% to 25%."

"The product is good, easy to upgrade, easy to use, and user-friendly."

"The most important point is the simplicity of the API integration. We can leverage the API integrations and connect our hybrid-cloud network environment with Nutanix's cloud storage."

"The product's initial setup phase was simple."

"DR and the replication power are valuable."

More Nutanix Unified Storage (NUS) pros

"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."

"The extreme compression of data is a big thing for us. We were looking for an online backup solution, and QoreStor is very good in terms of data compression. It helps us minimize the required storage in the Blob Storage environment."

"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."

"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."

"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."

"QoreStor has helped us to reduce our backup storage requirements on-premises. We've been using the same devices for quite a while, and so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution. The advantage here is even if we had to retire the hardware tomorrow, the QoreStor part doesn't change. We just have to have additional hardware and put the solution back on whatever hardware we pick and it'll do the same thing."

"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."

"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."

More QoreStor pros

Cons

"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."

"The features provided for SMB customers are limited."

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

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

"It's on the expensive side, as expected for a niche product."

"I would like to see more deduplication."

"The solution is expensive."

"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."

More Everpure FlashBlade cons

"The training programs could be improved. It's quite challenging to find adequate learning resources online, as there isn’t much available on the internet or YouTube."

"Lowering the price would improve this product."

"There should be more information. If it gets used more by more people, they will have a bigger community to share ideas. It is still kind of newer. It is not as big as Dell and other companies."

"I think Nutanix Unified Storage (NUS) can be improved with integration with vendors other than VMware or Dell, seeking more integrations with other storage vendors."

"When it comes to Nutanix Files, one thing that would be great is a slightly easier way of managing snapshots and restore points, especially when a third party is involved."

"When considering the difference in cost benefits, if you consider it only as a storage solution, you may find it expensive."

"The interface is not logical. It should be a little simpler."

"Improvement is needed regarding clarification to customers about storage capacity. While 100% storage is allocated, customers can only access 70 to 80% when examining deeply."

More Nutanix Unified Storage (NUS) cons

"The air gap feature is something I'd really like to see in QoreStor."

"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."

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

"The ransomware protection of QoreStor could use improvement."

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

"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."

"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."

More QoreStor cons

Pricing and Cost Advice

"The price is a little high."

"The product is very expensive."

"I feel that the price could always be lowered."

"The price could be cheaper."

"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."

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

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

"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."

More Everpure FlashBlade pricing and cost advice

"I'm happy with the cost and licensing because I don't have big volumes."

"The licensing model the tool has is cheaper than an HCI storage solution."

"With all of the Nutanix equipment, the licensing is expensive. We operate in the enterprise space, but we're a midsized company. At times, the price tag is a little bit shocking for a company with only 35 employees. We're not a Fortune 500 company, but we deal with Fortune 500 drug and energy companies. We have to play in that enterprise space if we're going to have enterprise customers. I'm very price-conscious, but I understand that if I want the best, I've got to pay the price."

"If we compare the cost of Nutanix Objects Storage to other solutions such as VMware licenses, our current choice is Nutanix Objects Storage. This solution is more cost-effective. However, adding VMware to Nutanix would not be a cost-efficient decision, which is why we do not use it anymore."

"The solution is highly-priced."

"In my opinion, the product is fairly priced."

"For clients running Nutanix, the licensing cost for Files is a small add-on cost."

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

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."

"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."

"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."

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