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.
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.

Solution lead at Globe Mobile
A versatile storage solution suitable for various workloads in cloud environments providing scalable architecture, granular Quality of Service and consistent performance
The most significant benefit lies in its exceptional performance, driven by its Flash-based architecture. This enhances routing speed and, consequently, database performance. The provisioning process is efficient and doesn't demand higher latency, ensuring optimal data transfer performance which is particularly valuable for tasks like data mining, where quick results are essential.

Quotes from Members

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

Pros

"We are finding the TCO of flash to be lower than SSD implementations."
"VMware has benefited our IT organization because we're 100% VMware, everything is running on it."
"The most valuable feature is the speed of it, as it is much faster than anything that we can get from similar competitors, and the solution helps to simplify storage."
"It saved a lot of space, as far as physical space in our data center."
"Provides fast access and is user-friendly."
"The most valuable feature of Pure Storage FlashArray is the complete set of functions it provides."
"The features that are there now are really what we need."
"The GUI is very easy to use and intuitive."
"I like its interface. It is very interactive and simple 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."
"What I appreciate about Nutanix Unified Storage (NUS) is that we have faced several issues in the Unified Storage, the compression and deduplication features have worked exceptionally well in the Unified Storage, and it has helped my business as it operates seamlessly without any interruption."
"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."
"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."
"I see that Nutanix helps to reduce the total cost of ownership in general."
"The solution is stable and extremely easy to calibrate."
"The performance of Nutanix Unified Storage (NUS) increased almost 50%."
"SolidFire provides seamless performance across your storage system when you need to scale up. Other storage systems do not do that."
"The most valuable feature of this solution is its scalability."
"It's a very compact device. For a medium-sized business, it's very helpful because the device is efficient and very fast."
"What is nice with SolidFire is that the QoS is embedded, and for each volume you create, you put the QoS on it, and you're sure to grantee the service level agreement for the customer, depending on the workloads he needs."
"If you buy the solution for its specific purpose it will work well."
"Provisioning times have gone down and a lot of the random errors from different things that we've seen across time kind of all went away."
"I would say in terms of architecture and in terms of functionality, the product is quite good."
"SolidFire is one of the products that does have great APIs right out-of-the-box; it works great, and the tools and the other stuff seem to work a little better right out-of-the-box than the ONTAP stuff does, C-Mode."
 

Cons

"The solution could improve by having a multi-tenant feature."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"I’d love to view the average, minimum and maximum performance in the reports (Analysis tab - Performance) but it is only graphics and you need to export data in CSV to find this information."
"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."
"The data reduction that we had initially anticipated when we bought Pure and we move over, is way lower than the expected reduction. It depends on the workloads, of course. But that has been a challenge at times."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"I would appreciate improvements on daily health checks."
"I think replication is one area that still needs improvement."
"The current hardware is not as dense as it could be. In our deployment, we have 2 PB per site, and we have to have 24 nodes. That's a lot of cabling and network ports that we use up. More dense nodes would be better."
"Allowing the use of the Gflag compromises the integrity of the Nutanix system and its established standards."
"There are some techniques that need to be improved because sometimes, during processes, it gets stuck on the console, requiring command line interventions, indicating gaps between the GUI and command lines."
"For improvement, the memory or storage should not exceed 90% capacity, as it becomes difficult to manage beyond this threshold."
"Requires higher upfront investment"
"The interface is not logical. It should be a little simpler."
"I acknowledge that the price of the product can be too high, and it would be beneficial if pricing were more flexible for end users."
"In summary for improvements, I would say stay on the integration path, keep those integrations heavy, and let us use the software and technologies with everybody."
"You don't have business continuity with SolidFire. I think it could be a nice feature to have in the future."
"The tool should improve its initial cost which is expensive compared to other products."
"For people using FC SAN, SolidFire is not an option because of the interface."
"The upgrade process could be better."
"A little better segregation of the multi-tenancy. Right now, it's just VLAN-specific, that's all you can do."
"On the negative side of it, I'm working on support, and I would get not enough detail or the support tech would say, "Check the manual.""
"However, when we wanted to change how we want to do it and basically start it over, do some hands on training with some of the architects who would be working on it, one of the issues was there wasn't an admin password at the BIOS level to restart it over."
"In fact, the price is quite high compared to other vendors, but what we really loved about SolidFire was the agility of the team."
 

Pricing and Cost Advice

"We do not incur additional costs beyond the licensing fee."
"Price is about the only thing that's wrong with it. A little bit better pricing would be great."
"Pure has been flexible with us on the pricing models."
"We lost a lot of customers because we couldn't compete on price with other vendors."
"The price is reasonable."
"It is cheaper than NetApp."
"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"Pure Storage FlashArray is expensive."
"The pricing is a bit too high."
"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."
"The price of the license is expensive when comparing it to traditional storage."
"I find Nutanix Files Storage competitively priced, even its feature set. Its price is seven out of ten."
"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."
"I'm happy with the cost and licensing because I don't have big volumes."
"The pricing of Nutanix is generally higher compared to other vendors, which is a common observation, but it provides value through its support and features offered to customers."
"From what I hear from the management, Nutanix Unified Storage has comparatively decent pricing."
"On a scale where one is a high price and ten is a low price, I rate the solution between three and four. It is an expensive solution."
"Based on what I heard from other people, its price was on the higher side."
"We would probably use SolidFire more, except we're getting more bang for our buck with our purchases of ONTAP right now, and the deal we made with NetApp, so it's more of just a cost decision"
"The price of this solution is more expensive than others."
"It might be considered expensive, but when evaluating performance, it represents good value online because you pay for what you get."
