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.

A robust solution with good performance and support
This is a solution that scales well, although I think that we have stabilized in terms of use. With respect to scalability, we have an open question as to whether we will be able to grow into a cloud-based deployment. We don't know in what ways this solution will assist us with the migration, or whether we can still use it for DR. We don't know about the type of backup, be it full, incremental, or otherwise. We are also looking for a cost-savings if we migrate. These are things that we will find out over time. We have about two petabytes of data.

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.

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

Pros

"I use all the features of this solution and I find them to be easy to use and functional, such as the compression and capacity to expand."
"The support has been very good from Pure Storage FlashArray."
"Because of the encryption, we have different storage and the encryption can go over both, therefore we are NCA compliant."
"I would recommend Pure Storage FlashArray to other users because, first, the speed that I get with Pure Storage FlashArray is not remotely possible with any other product at this price range, and second, the support is absolutely fantastic."
"It is the SAN backbone for our company."
"Pure support is very proactive, they monitor our infrastructure in real-time, so they respond before we even open a ticket."

"I would them to have more communication with other platforms, and it appears they are already doing that."
 

Pricing and Cost Advice

"I have had a couple of customers who have complained about the cost. It can be a little more expensive than some of the other platforms. After it has been installed, I have never had a customer say, "I wish we wouldn't have spent all that extra money." They have always been happy with the product after it has been installed. They might be on the fence about it because of the price, but everybody who I have ever seen install it, they are always happy with it."
"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."
"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"Dell and Pure Storage offer competitive pricing, but Pure Storage might have a slight advantage."
"The pricing of Pure Storage is all-inclusive. It is very fair, and very easy. In comparison, Dell EMC has licensing that needs to be added if you wan to work in a complex environment or in specific functionalities."
"My organization has a yearly license, but I believe that Pure Storage FlashArray has capacity-based licenses as well. I'm definitely happy with the pricing."
"There are no licensing fees aside from the support."
"The best features come included without any additional cost."
"For a database, on a yearly basis, we pay approximately $3,500 for licensing fees. The solution is sold as a subscription on a yearly basis so there are no other ancillary costs."
"If you are cost-sensitive then this solution is not for you."
"Nutanix Unified Storage was cheaper than other solutions we evaluated."
"It is competitive with other vendors, but you get more for your dollars. It is fairly priced, but not cheap."
"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."
"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."
"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."
"From what I hear from the management, Nutanix Unified Storage has comparatively decent pricing."
"In my opinion, the product is fairly priced."
