Technical Lead at Wipro Limited
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.

Good customer service and support and suitable for large environments
It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

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

"What I like most about this solution, is the speed, resiliency and scalability."
"Compared to Unity, these arrays offer significant advantages, such as NVMe technology and higher IOPS."
"The tool has reduced our power consumption."
"It's a great return on investment, based on the mission."
"This solution has helped my organization by cutting down on provisioning time. I used to have to provision a VM and it would take ten minutes. Now, it takes thirty seconds."
"The solution has great efficiencies because it has scalability."
"From the first test that we have conducted, we are very satisfied with this solution."
"It is fast and reliable. It works."
"Ease of Use: Someone can learn it in only few hours Performance: Easy Tier is doing miracles Data Compression: Up to 80% space reduction in the database"
"High performance and ease-of-management are the most valuable features."
"We use IntelliFlash products for larger environments, like Qatar Airways."
"The initial setup is straightforward."
"Once we got this solution in there, we were able to get the reporting down from eight hours to under 20 minutes."
"After five years, the cost decreases over 30% and the performance increases over 50%."
"We have been able to realize storage space savings for our virtualization environment and it has reduced our electricity usage by reducing the number of disks needed for the virtual environment."
"Data Compression: Up to 80% space reduction in the database"
"I strongly recommend Nutanix Unified Storage (NUS) to all users as a modern cloud computing system, offering significant cost savings for clients, customers, and vendors while providing excellent cloud infrastructure operations."
"The real-time alerts generated by this system enable us to swiftly address and mitigate such threats."
"After working with other Nutanix solutions, I can say that everything has a purpose, and it is pretty bulletproof."
"Nutanix support deserves a rating of nine out of ten."
"Nutanix Files is a complete solution in the Telco Machine and offers a host of benefits, including easy management, upgrading, and analytics of new data."
"The most valuable features of the solution are replication and backup and our company needs a tool to help us with disaster recovery and the security of our data."
"One of the main features of Nutanix Unified Storage (NUS) that I find most valuable is the flexibility and scalability of it, as well as the ability to perform replication for our Disaster Recovery environment."
"From an analytics perspective, the best aspect of Unified Storage is its locality. When you read data, you want to know that you're only reading data from the particular local storage node. It's also critical to access the data as quickly as possible from that. From a business perspective, the most important thing is ease of use. Having a combination of compute and storage makes it much easier to manage."
 

Cons

"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"Based on my experience with various technologies like EMC, NetApp, and Pure Storage, one area for improvement is compliance certifications. NetApp excels in this area, particularly in the American Army or defense sector, where NetApp has approval, whereas others are striving to achieve the same. NetApp also delivers security, ransomware protection, and scale-up capabilities more effectively."
"It was a little costly."
"We would like to see more cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array."
"A noticeable area for improvement is the support for object storage. The FlashArray does not natively support object storage like S3 or Swift, which pushes customers needing these features towards the more expensive FlashBlade."
"I would like to see them develop the ability to integrate with more AWS services."
"The pricing needs to be improved as they offer very high budgeting prices. Searching is a big challenge in Pure Storage FlashArrays, especially when trying to restore a VM."
"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."
"I would say it's somewhat scalable, maybe not so much as some of the competition, but we don't really care."
"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."
"In future releases, I look forward to more AI features."
"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"It's annoying that if you turn on SMB3 (as opposed to the earlier CIFS protocol), then it is not possible to access a file store using a mixture of SMB and NFS."
"Snapshots are not as easy to access as on a NetApp device."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"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."
"The implementation is a little bit complex and should be made easier."
"The feature request I have is for the consistent improvement of how user account permissions are assigned in Nutanix Unified Storage."
"There are some processes, like if I like to change the data storage to another place, I have to use CLI, and I don't like it since I believe that it could have been simpler in GUI."
"Improvement is needed regarding clarification to customers about storage capacity. While 100% storage is allocated, customers can only access 70 to 80% when examining deeply."
"Security is an area for improvement. When there are vulnerabilities, there needs to be a faster approval process. The solution needs to automatically target the vulnerabilities and not waste too much time."
"There should be more information. If it gets used more by more people, they will have a bigger community to share ideas. It is still kind of newer. It is not as big as Dell and other companies."
"The dashboard could be more customizable"
 

Pricing and Cost Advice

"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"The license for Pure Storage FlashArray includes the support and there are no additional payments that are needed. This is not an inexpensive solution, you need to understand the value of your data before you use a backup solution."
"FlashArray is expensive, but the quality justifies the price."
"Pricing is moderate. It is neither cheap nor expensive."
"The pricing of Pure Storage FlashArray is reasonable."
"It's expensive, but you get what you pay for."
"There is an annual or perpetual license required for this solution."
"We consume it as a service, and that's actually something we really like, or at least I really like from the technical perspective. That's because it means there is no hassle when we need to upgrade arrays to add capacity. We just interact directly with technical counterparts, and we say, "Hey, we're filling up," and they say, "All right, here's another data pack." They ship it in, and we install it. So, the as-a-service model has worked very well. Given the outstanding data reduction rates, it has improved our profitability because we're selling allocated volumes as part of the cloud service or recovering those costs from our tenants. It is very efficient, but that has offset the premium price. It started out that way, but over time, as we've added capacity, the price per gig has gone down a lot because we have a lot of it."
"I think we pay around 100 grand per year for three arrays or four arrays."
"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."
"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."
"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."
"Nutanix Unified Storage pricing is reasonable."
"From what I hear from the management, Nutanix Unified Storage has comparatively decent pricing."
"My company is in Brazil, and making the payments in dollars is tough for our organization."
"Nutanix Unified Storage is competitively priced. There aren't any competitors that can do much better for the same price."
"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."
"The price can always be improved. As a customer, you always seek reasonable solutions within your budget, and they give us little to do a lot. My IT team always has to justify that we are choosing an optimal solution, so the price could be a little lower Maybe the prices could be a little bit lower."
