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.

Reliable flash storage has delivered strong data reduction and secured sensitive information
There is still some room for improvement when it comes to scalability, mainly in the interoperability and integration aspects. Every storage vendor has certain limitations, and this is not limited to NetApp; it applies to everyone in the industry. I do not see any other significant areas for improvement with NetApp AFF C-Series at this time. NetApp is working on their roadmap, which is solid, and they are developing certain features that are yet to be released.
NISHANTPANCHAL - PeerSpot reviewer
Principle Technical Specialist at a comms service provider with 1,001-5,000 employees
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

"The most valuable feature is it never goes down. We can expand and create volumes."
"The most valuable feature is its upgradeability."
"Once we solved the data reduction and what Pure does we were hooked."
"It reduces space and the polar consumption. It also accelerates the application."
"We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."
"The most valuable feature is replication."
"It's very fast, easy to use, and the cloud-based management is good."
"The deduplication and compression meet all of our system requirements."
"NetApp offers a cost-effective solution with very robust hardware."
"NetApp AFF C-Series is a good product for entry-level flash storage, the system is competitive in terms of pricing, and the value proposition is strong."
"I rate Nutanix Unified Storage (NUS) nine point five to ten, as it's easy to manage, scalable, has great performance, and includes advanced features."
"The best Nutanix Unified Storage features are its recovery and data speeds. It has resolved the issue of accessing information quickly."
"Unified Storage's centralized management features enable us to accomplish whatever we want in terms of operations and migrations."
"I find that Nutanix’s resilience is the most valuable because it is a feature that is not found in other technologies."
"Customer support for Nutanix Unified Storage (NUS) is top-notch."
"My experience with using Nutanix Unified Storage (NUS) for data-intensive workloads is that we have many SQL Servers and they perform much better than they did when we used hybrid converged previously."
"I would recommend Nutanix Unified Storage. It's easy to use, and they are the best when it comes to storage services."
"Nutanix Unified Storage is a stable solution that provides good storage and efficiency."
 

Cons

"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"We haven't seen ROI yet."
"For scalability, I rate it a six out of ten. We reach a limit. We never reached this limit, however, the architecture allows you to go until a certain size, and after that, you have to buy another array."
"The price is too high."
"It took us a year to get it to stabilize and to get the best out of Pure."
"Many high-end platforms from other vendors like Dell EMC or Hitachi, their backend has Active/Active architecture, unlike Pure Storage FlashArray which doesn't utilize an Active/Active architecture on the backend."
"I wish they could add more of a monitor on the machine itself so you don't have to rely on a KVM or something to look at the display, such as an onboard diagnostic display."
"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 still some room for improvement when it comes to scalability, mainly in the interoperability and integration aspects."
"We faced one bug that impacted our NetApp last month, and it took some time to identify the underlying issue."
"Pain points are just in the management and understanding of how the functions work. As far as updating and day-to-day operations, if my staff is properly trained and we have those proper training sessions, we don't have that many issues. There can be more educational resources from their side."
"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."
"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."
"For P1 and P2 alerts in the Nutanix Unified Storage (NUS) file share system, including SMB, NFS, objects, or blocks, we must maintain vigilant monitoring. This is crucial because system downtime can disturb the entire ecosystem and impact all applications."
"From the speed perspective of Nutanix Unified Storage (NUS), it could enhance some features to make it the best storage solution in the market."
"The CVM consumes more memory and CPU, as it will be allocated a minimum of 32 GB. For a large data store, they are unnecessarily consuming extra resources through the built-in CVM."
"Requires higher upfront investment"
"Another aspect that needs improvement is continuous protection against security threats such as ransomware and potential data leakage."
 

Pricing and Cost Advice

"The cost has room for improvement."
"The price is reasonable."
"Price is about the only thing that's wrong with it. A little bit better pricing would be great."
"Pure came in at a better price point than EMC and performed better than Compellent."
"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."
"The solution is expensive."
"You get what you pay for. It is expensive, but it really works."

"Nutanix is priced a bit higher than some of its competitors. A lot of Chinese companies like Huawei are entering the Saudi Arabian market trying to provide similar solutions for a lower price. It offers a good value, especially the support. Nutanix has a highly competent team. The after-sales support is excellent."
"It is not too high for what we are using."
"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."
"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."
"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 product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."
"The licensing model the tool has is cheaper than an HCI storage solution."
"The pricing is a bit too high."
