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.

Has improved data reliability while requiring better pricing and localized support
The most valuable features of Arcserve OneXafe are improving persistent data, which I believe is very important. I use other products too, not only Arcserve OneXafe; we use TrueNAS as well. I have utilized Arcserve OneXafe's data deduplication feature. It helps my storage efficiency significantly. The product satisfaction with this product helps with storage efficiency. Regarding Arcserve OneXafe's immutable object storage helping against ransomware, the call was not clear, and I had difficulty listening to what was discussed. Arcserve OneXafe improves precision of data. I have used Arcserve OneXafe's continuous data protection. This is beneficial for operational continuity because we use it constantly. I have no objections to Arcserve OneXafe technology; I think that is very good.
NISHANTPANCHAL - PeerSpot reviewer

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

"The cost of Pure FlashArray is a bit high compared to peers, but its sustainability and features justify the price."
"When we needed to replace the other arrays, we went straight to Pure and life-cycled them into Pure in every segment we have."
"The most valuable feature is its data reduction."
"Everpure FlashArray is probably not cheap storage, but it provides great performance, scalability, and everything a customer needs."
"With Pure Storage FlashArray we have been able to deploy several thousand VDI servers, virtual machines, very quickly and efficiently."
"It's very fast and very easy to use. It performs well and is both flexible and compatible. We like it because it's easy to use."
"Even if it costs a little bit more, you do get more for what you pay."
"Now, with Pure Storage, we have totally eliminated that problem."
"The most valuable features of Arcserve OneXafe are improving persistent data, which I believe is very important, and I have utilized Arcserve OneXafe's data deduplication feature, which helps my storage efficiency significantly."
"The simplicity and the ability to perform small backups are the most effective features for data protection in Arcserve OneXafe."
"The solution is very easy to manage."

"Nutanix Unified Storage (NUS) has simplified my storage management across different workloads and improved application performance and availability while supporting hybrid cloud and modern applications with centralized management."
"The customer service executives of all Nutanix products are active and responsive."
 

Cons

"I would like to see them develop the ability to integrate with more AWS services. There are increasingly more and more services coming out from AWS but there are also certain constraints where we can't move everything over to a cloud as well. We would like for things that are on-premise to be easily integrated with AWS."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"I find the pricing of Everpure FlashArray to be quite high compared to other storage solutions; however, the reliability and features are commendable."
"For large storage needs, it is expensive."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"Enhanced documentation and beginner-friendly guidelines would benefit users with less configuration experience."
"The price of the solution can improve."
"What I dislike about Everpure FlashArray is that in the replication, if it is in the pod, we cannot directly add devices to the pod without breaking the relationship."
"Arcserve OneXafe is not used in many cases in the market that we work in."
"The price is not the best; it is too high. It's not the best solution in terms of price, although the solution itself is good."
"The price is not the best; it is too high."
"Perhaps when it comes to deploying NUS virtual machines on top of CVMs, it should not be necessary for it to be in all of them or they should require fewer resources on the servers."
"One thing I'd appreciate is having a desktop application similar to what VMware offered."
"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."
"There is some confusion in the reporting when I have to create the report for statistics. I find it is not so user-friendly."
"The product does not offer one console."
"The solution should increase its storage capabilities, as it has been required to make use of local data storage and local pockets and magnets."
"The solution should include more protocols to access data."
"The problem is that we need to invest a lot of money to get AI, and therefore, we are not going to purchase AI right now."
 

Pricing and Cost Advice

"Pure Storage FlashArray's pricing is very competitive."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."
"We do not incur additional costs beyond the licensing fee."
"The cost of Pure Storage is subjective and determined by your environment. Pure Storage tends to be more expensive than NetApp, but it is cheaper than EMC. Performance varies with data workload, making cost considerations complex."
"There are no licensing fees aside from the support."
"The pricing is reasonable."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
Information not available
"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."
"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."
"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 solution's pricing is fair."
"The product is pricey."
"I'm happy with the cost and licensing because I don't have big volumes."
"Licensing-wise, I have no complaints. Their license is pretty simple and easy. It gives us everything we need, so I have no complaints about licensing."
"It is competitive with other vendors, but you get more for your dollars. It is fairly priced, but not cheap."
