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.

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.

Stability-wise, a device that has been up and running for years
The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"My favorite feature about Pure Storage FlashArray is definitely the simplicity; in one word, it's simple to install, simple to upgrade, simple to maintain, and simple to manage."
"The performance is great."
"FlashArray's data reduction and NAS features are incredible. Its performance is the best I've worked with."
"Pure Storage FlashArray has helped us to improve the reporting and the billing cycle."
"Their support is top-notch, and their NPS scores reflect this."
"Very efficient storage"
"My advice to others looking into using Everpure FlashArray is that it's a really good product, especially if your main purpose is to get high speed with more redundancy and reliability; then go for it."
"The best features of Pure Storage FlashArray are its ease of use and user-friendly interface, and the performance allows all types of services to be visualized from a single point of interface, making it more robust and user-friendly."
"The best features of Nutanix Unified Storage (NUS) are its simplified management, scale, and performance; data services can be easily consolidated, which help in disaster recovery services, replication, and reducing complexity and costs associated with this architecture."
"My opinion is that this solution has very good stability."
"Nutanix has excellent product documentation available on their portals, written in simple, easy-to-understand language."
"The integration with Prism Central makes it a lot easier to manage, so we just have a single pane of glass location that we can go to. We do not have a separate admin console or anything that we have to use."
"The biggest return on investment for me when using Nutanix Unified Storage (NUS) is the management aspect since it's easier to manage."
"We had three racks full of storage and now it is just half a rack."
"The most valuable feature is the unified dashboard, as it allows us to easily observe everything from a single location."
"Nutanix Unified Storage (NUS) can meet any storage need that a company has, such as traditional block storage for NFS or virtualization, and it can deliver a file solution for different kinds of needs of a company, and even objects for backup, for logs, for data lakes, for image repositories."
"This has been one of the most reliable storage systems that I have ever used."
"The solution is useful for machine learning and scientific applications, including computer simulations."
 

Cons

"The GUI could improve, it could be more intuitive. There is hidden functionality."
"I like what they're doing, but some of my customers complain that they do not have all the bells and whistles and knobs to fine-tune workloads that some of the competitors have. In my opinion, that's good. All customers don't have dedicated storage gurus, and they can get themselves into trouble if they fine-tune too many of those high-performance knobs, but they do get knocked down. Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE. I personally think 95% of my customers are better off letting the system fine-tune itself. That was something that you needed to do 12 or 15 years ago, but now with all-flash, the technology can handle what it needs to handle. Customers just end up shooting themselves in the foot if they are tweaking too many default settings."
"CIFS and SMB Shares cannot be mounted directly."
"It would be good to have metrics of the box's performance so we can see what it delivers, but currently, I can't see what it's actually doing."
"I would prefer that they lower their pricing."
"Everpure FlashArray can be improved as the pricing is expensive, but you do get what you pay for; you are paying a premium for better service, better warranties, less downtime, and other things, so I do not know that a lower price would work out because you probably would not have that high of quality for those things."
"I would like to have support available in Spanish."
"The only thing is that we've had to upgrade controllers a few times because we ended up wanting to use more stuff on here."
"There is some confusion in the reporting when I have to create the report for statistics. I find it is not so user-friendly."
"From the speed perspective of Nutanix Unified Storage (NUS), it could enhance some features to make it the best storage solution in the market."
"I believe that one of the most complicated parts of Nutanix Unified Storage is the configuration of the DNS issue in Active Directory. Sometimes it is a bit complicated to troubleshoot or detect an error when integrating it with Active Directory."
"The integration feature with Nutanix Unified Storage (NUS) could be improved, maybe into a more stabilized version."
"From a management side, the one thing I would prefer is if it were a bit less expensive for smaller enterprises. It's a bit costly. If they provided flexible modules where you could pick and choose features, and only pay for what you use, that would be an improvement."
"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."
"The interface is not logical. It should be a little simpler."
"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."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
"The write performance could be improved because it is less than half of the read performance."
 

Pricing and Cost Advice

"The price of Pure Storage FlashArray could always improve. They are still more expensive than some alternative offerings. Cost is always a concern and when there is a battle they tend to be more expensive."
"We feel that the pricing is fair and the licensing process was easy for both."
"The pricing is very attractive and it delivers performance for the money."
"Pure Storage FlashArray is expensive."
"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 is always room for negotiation."
"It could always be lower, but it's okay."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"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 cost of Nutanix Unified Storage can be prohibitive for some small and medium-sized businesses, making it challenging for them to adopt the product."
"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 solution is highly-priced."
"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 not too high for what we are using."
"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
