Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades
The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

Performance and interface improve data processing speeds but require complex configuration
The most valuable features of VMAX are its performance and GUI interface. We have seen significant improvements in technology over the last four to five years. The snap feature, along with deduplication, has notably enhanced our data processing speeds. We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution.

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.

Quotes from Members

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

Pros

"Everpure FlashArray has positively impacted my organization, particularly in performance and reliability, as we've had good improvements, making our applications run faster and giving us more confidence that they will not crash."
"The mobile app is very helpful."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."

"One could tell, the minute we switched to this program, everything ran a lot faster."
"The solution helps to simplify storage."
"Pure Storage FlashArray says no to forklift upgrades; usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime—everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray."
"It has been quite satisfactory in performance and scalability."
"The snapshot feature has been precious for our testing processes, application development, and managing testing environments due to its efficiency and ease of use."
"The product's initial setup phase was good."

Cons

"Pure Storage had operational challenges between 2016 to 2018, impacting perceived reliability."
"Price is about the only thing that's wrong with it."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"I would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side."
"A noticeable area for improvement is the support for object storage."
"In the next release I would like to see integration into other third-party player providers like Google."
"I’d love to view the average, minimum and maximum performance in the reports (Analysis tab - Performance) but it is only graphics and you need to export data in CSV to find this information."
"It would be beneficial to have a health check command that can be run from the CLI to ensure that all hardware components are functioning properly rather than having to enable remote access and connect to support for a health check."
"Improvements are needed in both partition recovery and scalability."
"The configuration part of the product is an area with certain shortcomings where improvements are required."

"I have heard that there have been latency problems."
"For improvement, the memory or storage should not exceed 90% capacity, as it becomes difficult to manage beyond this threshold."
"I would like Nutanix to provide a solution for virtual disks. This is the main problem for which we want a solution."
"One area where Nutanix Unified Storage (NUS) has room for improvement is in rollback capabilities. If I update, I cannot roll back to a lower version, which I feel is a major drawback."
"Security is an area for improvement. When there are vulnerabilities, there needs to be a faster approval process. The solution needs to automatically target the vulnerabilities and not waste too much time."
"While the stability of Nutanix Unified Storage (NUS) is good, the need for manual intervention can be a drawback."
"We have had to deal with some infrastructure and general cluster issues but these issues don't impact storage."
 

Pricing and Cost Advice

"The price of the solution is not expensive."
"It is cheaper than NetApp."
"We are finding the TCO of flash to be lower than SSD implementations."
"The price is reasonable."
"We purchased a license to use this solution and we pay for the storage ourselves."
"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."
"We have seen a reduction in total cost of ownership."
"For us, as the customer, it reduced the price of the management."
"It is not a cheap product."
"The price falls within the mid-range, neither inexpensive nor high-priced."
"It's not the cheapest solution. It's in line with other solutions, but it offers features that the competitors don't have at any price point, especially with regard to analytics and ransomware prevention. No one else has any sort of object-based storage available. Nutanix Unified Storage is a lot more feature-rich. This is a situation where you get what you pay for."
"The product has an annual licensing fee."
"The licensing currently works based on a software license. If we have files, volumes, and other licenses combined, that would be more valuable. I don't want to go for a separate license for files and a separate license for volumes. We have unified storage, so the licensing should also be unified. That would be helpful."
"The pricing is fair."
"I assume Nutanix Unified Storage (NUS) has helped reduce our total cost of ownership."
"The price of the license is expensive when comparing it to traditional storage."
"We are Nutanix partners, so it is pretty good. With the free terabyte that comes with the Nutanix clusters, we have started to build proposals for the clients. The price adjustment with the new policy of Nutanix Unified Storages seems attractive. Let us see if it has results."
"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."
