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

"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 initial setup is very straightforward. You simply plug it in and turn it on."
"The solution offers amazing performance."
"We have looked at all of the platforms, and to see what Pure was able to do within a PoC environment meant that we never turned back our PoC environment."
"This solution has improved our organization in the way that we used to see latency but now with this solution we don't. It also has good performance. Latencies have come down for our performance in the SQL databases. We can put a lot more in a lot less in terms of space savings. We also save data center space have good deduplication."
"Pure Storage FlashArray provides immediate benefits to our customers with its easy setup process, allowing for instant use and rapid realization of advantages."
"The performance is very good."
"Non-disruptive upgrades: You can upgrade at anytime without worry."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"After five years, the cost decreases over 30% and the performance increases over 50%."
"We use IntelliFlash products for larger environments, like Qatar Airways."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks Cheaper than pure solid state without needing to actively manage where the data is located."
"It performed great originally, and when it performed great, it was awesome."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"It has cut batch job runtime in half, so we're seeing performance improvement throughout the organization."
"Tegile All-Flash Storage Arrays deliver maximum performance, high density, compelling economics and it is ideal for latency-sensitive, business-critical workloads such as online transaction processing, real-time analytics, decision support, and data warehousing."
"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."
"What I appreciate most about Nutanix Unified Storage (NUS) is how easy it is to use and how simple it is to create new volumes and containers, and it's pretty quick."
"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 capacity is very good. They use fewer nodes than before. Each node is isolated with the CPU with the performance. It is a cluster node but works separately, so the performance will be tripled."
"The solution's most valuable features are its support and speed."
"The solution is stable and extremely easy to calibrate."
"Nutanix Unified Storage (NUS) is very scalable."
"Unified Storage's centralized management features enable us to accomplish whatever we want in terms of operations and migrations."
 

Cons

"On the technical side, the way that the array performs cleanup and garbage collection sometimes pushes it close to 100 percent utilization, causing some stress."
"If there is one thing that I did not appreciate about Pure, it is that between the two different lines, which would be FlashBlade and Everpure FlashArray, there is no easy way to migrate LUNs as far as being able to replicate across those platforms."
"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."
"The product should improve its response time. I have also encountered issues with its configuration."
"Everything has been good, but we faced one issue last year while migrating volumes from one Pure Storage to another. The snapshots were not visible in the Veeam backup portal."
"I would recommend improvements in the graphical user interface, specifically a detailed hardware view that would allow us to see the individual drives and individual controllers more easily, as currently, they are presenting only a higher-level view."
"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."
"In the next release of the solution I would like to see Vormetric native block encryption."
"I would say it's somewhat scalable, maybe not so much as some of the competition, but we don't really care."
"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."
"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"The solution as it is right now is not very stable. The stability seems to have eroded."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"The monitoring matrix and its dashboard need work."
"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."
"We have issues with software updates occasionally."
"The product does not offer one console."
"For future updates, I think Nutanix Unified Storage (NUS) should look at features similar to what ONTAP of NetApp is doing, such as tiering to the public cloud."
"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."
"Allowing the use of the Gflag compromises the integrity of the Nutanix system and its established standards."
"Pain points are just in the management and understanding of how the functions work."
"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."
 

Pricing and Cost Advice

"Pure Storage has not helped to reduce our HANA licensing costs."
"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."
"Pure Storage FlashArray's pricing is very competitive."
"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."
"We have seen a reduction in total cost of ownership (TCO)."
"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."
"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."
"Nutanix's pricing is definitely much better when compared to other storage providers. That was one of the main reasons we switched to this platform."
"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 Unified Storage isn't expensive."
"From what I hear from the management, Nutanix Unified Storage has comparatively decent pricing."
"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."
"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."
"It is very good. It is much more competitive than a dedicated storage platform."
"The solution's pricing is fair."
