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.
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

"Data deduplication is one feature I found to be the most valuable in the tool...Stability-wise, I rate the solution a ten out of ten."
"We were actually able to do multiple upgrades, including head upgrades and moving between the platforms, M20 and M50, over the years. We have never once lost a ping and have never had an outage due to an OS upgrade or a complete head upgrade."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"Technical support is very good."
"The console is simple to use. It has good performance. It is easy to install, understand, and manage, with a good ratio of deduplication and compression. It is doing its job."
"It is pretty much just plug and play. There is not that much to do with it. It is very easy to use."
"The pricing of Pure Storage is all-inclusive; it is very fair, very easy, and the solution is a lot easier to install than the Dell EMC product."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"The ease of use is the solution's most valuable aspect; it's very user-friendly, and the security on the product is very good."
"Implementing this solution has been a very good decision for our in-house data center."
"The most valuable feature is the robustness, which is typical of IBM because their software generally just works."
"Some of the features that we use include replication and snapshot capabilities, especially from remote locations to our data centers. The main benefit our company sees from using Nutanix Unified Storage is simplification. In the past, we used three-tier solutions with a lot of complexity and operational overhead. Now, we want to focus on the layers above. I want to have storage available, but I don't want to have to think about it. I want it to work without any issues."
"It is more stable and scalable compared to the Windows file server."
"It removes a layer of aggregation to present storage to end users, so we do not have Windows file servers. This benefits our company by reducing one of our attack planes from a cybersecurity perspective, so we do not have to worry about the OS."
"They have well-documented best practices and the interface is good."
"Nutanix is totally reliable and very stable, it operates 24/7."
"The product's initial setup phase was simple."
"Nutanix Unified Storage (NUS) is very scalable."
"The performance of Nutanix Unified Storage (NUS) increased almost 50%."
 

Cons

"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"Going forward, don't complicate things for the customers."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"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."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"The solution is expensive."
"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"The reporting mechanisms need improvement."
"The interface is not user-friendly so the ease of use could be improved."
"The product needs to work a bit more on its ransomware detection capabilities."
"We have issues with software updates occasionally."
"As you have to go through all of the steps of technical support, it takes longer to get to an escalated level."
"A centralized file share permissions console might be useful for Nutanix Unified Storage (NUS). Getting in and directly managing permissions instead of using the snap-in from Windows itself might be something to consider, but that's a small thing."
"I would not recommend Nutanix Unified Storage (NUS) to other users or developers because it does not support fiber channel (FC) or NVMe storage, and only supports iSCSI, which I believe is outdated technology in today's market."
"The dashboard can have more details and be more useful."
"Nutanix Unified Storage (NUS) needs improvement, particularly for firmware upgrades, as sometimes updates take a whole day and it can be unclear whether the issue is with Nutanix Unified Storage (NUS) or the hardware, requiring us to reconfigure everything, which is a main point we want consolidated into one solution."
"According to the keynotes announced by Nutanix the previous day or this morning, the data storage for Kubernetes requires improvement as it has a few shortcomings in the area of operations."
 

Pricing and Cost Advice

"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."
"Because of the SSD, it is cheaper because I am not purchasing so many disks."
"The price-to-performance is good. I looked at Pure about three to four years back, but the price-to-performance wasn't right for us. Now, it's right."
"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"Pure Storage has not helped us to reduce our licensing costs."
"We evaluated Oracle and Hitachi, but Pure Storage had the better pricing."
"It is light years beyond anything else with the same price point."
"You get what you pay for. It is expensive, but it really works."
"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."
"I am not the one who makes the calls, but it seems to me that it was very competitive. Other solutions would have required dedicated hardware, so an additional CapEx has to be put in place. In that sense, it was definitely a more competitive option to go with Nutanix Files."
"The pricing is fair."
"If we compare the cost of Nutanix Objects Storage to other solutions such as VMware licenses, our current choice is Nutanix Objects Storage. This solution is more cost-effective. However, adding VMware to Nutanix would not be a cost-efficient decision, which is why we do not use it anymore."
"Nutanix is very competitive."
"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."
"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."
"The solution’s pricing could be cheaper."
"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."
