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

"From an investment standpoint, the support staff I require for it is greatly reduced, so I don't have the in-depth requirements that I had on other products."
"We have seen a good reduction in the amount of total storage space that we're using because of the deduplication."
"One of the lesser sung advantages was when we started running our interface engine on Pure Storage. The ability to process messages and pass them through in our organization skyrocketed purely because of a disk that I owned which we were getting out of Pure Storage."
"Its array houses our entire production environment."
"Their technical support is excellent. It's the best out of any of the vendors we work with."
"It is an SSD array that has awesome performance, low submillisecond latency, and does what it is supposed to do. It just works, which is difficult for things to do anymore."
"Compared to other storage boxes, Everpure FlashArray is very useful because it is cost-effective and requires less work."
"There was a dramatic improvement in operating costs just as a result of the environmentals and space, let alone the cost of the unit itself."
"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."
"In the beginning, when they sold us Nutanix Unified Storage (NUS), they told us the performance would be 30%. Then we came to them and said, 'You are a liar. It's not 30%, it's 800% increase.'"
"For customer service and technical support, I would rate them a nine out of ten."
"The availability of the environment is incredible, and with Prism Central, you're able to diagnose and go over issues quickly."
"The solution's most valuable features are its support and speed."
"The product's benefits stem from the ease of use and management it offers to its users."
"The solution is easy to use, share, and manage."
"Now, we have much more control over our File Share environment, it is much easier to manage, and we've reduced the IT infrastructure footprint by 70%."
"The solution is simple and robust."
 

Cons

"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."
"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."
"The GUI could improve, it could be more intuitive. There is hidden functionality."
"I have been primarily working with storage and have not fully explored other areas, but there is some room for improvement when it comes to performance reporting."
"It's expensive, but you get what you pay for."
"We understand that they're thinking about it, but one of the things that would be nice is if they added some basic file-level capabilities to the platform. The idea is that they would run a basic NFS or CIF share from the controllers. FlashBlade is the powerhouse for File and Object storage, but if you don't need all that power, a lightweight file function would make FlashArrays more versatile."
"It is not possible to create a cluster on top of multiple arrays."
"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."
"The price is not the best; it is too high."
"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."
"Arcserve OneXafe is not used in many cases in the market that we work in."
"There is some confusion in the reporting when I have to create the report for statistics. I find it is not so user-friendly."
"Its interface is very simplistic. It is a good thing for people because of the ease of use, but at times, I find it too simplistic. It is hard to find advanced options. They should eventually expand it and provide additional drop-down lists or menus with advanced feature sets."
"Improving quota policies would be advantageous, particularly by offering the option to implement blocking instead of just issuing warnings."
"The GUI is not user-friendly for new users and has room for improvement."
"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."
"Customer service is more difficult to call and they do not responding as much as, for example, DataCore. It's not the same level of satisfaction compared to DataCore. Responses could be faster."
"The product does not offer one console."
"The dashboard can have more details and be more useful."
 

Pricing and Cost Advice

"The price of Pure Storage FlashArray is expensive."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."
"Cost-wise, it's been very effective."
"The licensing is $100,000."
"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."
"I don't know the exact cost but it's around $1,000."
"Because of the SSD, it is cheaper because I am not purchasing so many disks."
Information not available
"I'm happy with the cost and licensing because I don't have big volumes."
"I find Nutanix Files Storage competitively priced, even its feature set. Its price is seven out of ten."
"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."
"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."
"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."
"The product is pricey."
"Nutanix is very competitive."
