All-flash storage has unified my clients’ workloads and has reduced TCO through efficient data services

The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors. IBM, Lenovo, and Dell are more aggressive on prices. It is a very complicated market, especially now, and I understand the prices are higher at Everpure because of the software and all the enhancements it has. However, in this competitive market, we have a big problem selling to customers that are on a tight budget. A product with better pricing would be a win in the end. The RC or C20, for example, was a very good product that I could sell more easily than other options. Everpure FlashArray//C is sufficient for most workloads and virtualization workloads if you do not have very large databases. A product like that helps, and perhaps a new product in the future that is a little cheaper than the current options would be a possibility to gain more market share. I see the return on investment clearly from using Everpure FlashArray, but the challenge is selling it to customers for the first time. There are many customers who fall in the sweet spot where they are too small for an X or even a C model. They need something a little cheaper, they have the money for a cheaper version, and they need the performance of a Pure system. These customers could be more easily approached if Everpure offers a version of a local device in the future that is even cheaper than the C-class. I am trying now to help customers understand the concept behind AG1. I know that AG1 is not profitable if capacity is less than 50 terabytes. However, some customers would be very willing to pay for 25 terabytes in a cloud operated by Pure and to have it accessible with very good speed. We will see what the future brings.

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

"My favorite feature about Pure Storage FlashArray is definitely the simplicity; in one word, it's simple to install, simple to upgrade, simple to maintain, and simple to manage."

"FlashArray's data reduction and NAS features are incredible. Its performance is the best I've worked with."

"My advice to others looking into using Everpure FlashArray is that it's a really good product, especially if your main purpose is to get high speed with more redundancy and reliability; then go for it."

"The code upgrades are very smooth."

"The tool has reduced our power consumption."

"I have never experienced an outage with the product or had any support that was below excellent."

"Running SAP on Pure Storage helps a lot without doing any further tuning to improve application performance. Our internal clients are happy."

"After switching to Everpure FlashArray, we saw significant results, as whatever hardware we used before is now compressed to 80%, maximizing space utilization in a single system."

More Everpure FlashArray pros

"Fusion provides the ability to install the secret server and distribute files; it serves as a black box where tickets are opened only if issues arise, reducing frequent upgrade problems."

"I would rate Nutanix Unified Storage a ten out of ten."

"The product's benefits stem from the ease of use and management it offers to its users."

"The most valuable features of the solution are high availability and synchronization to another location."

"For customer service and technical support, I would rate them a nine out of ten."

"Regarding downtime issues, we haven't had downtime in generations, and everything is going very well."

"The solution's most valuable feature is the Prism Central centralized management console."

"It scales well. I started with two or three servers, and I have added almost 20."

"I find that Nutanix’s resilience is the most valuable because it is a feature that is not found in other technologies."

More Nutanix Unified Storage (NUS) pros

Cons

"I would love to see a true one click upgrade solution. Right now, you have to click and schedule an appointment with Pure Storage to be able to upgrade. I would love for it to automatically download, install, and fall-over every controller as it updates."

"I would like to see the NAS add-on component become more fault-tolerant than just a single virtual machine running inside the array. I'm unwilling to use it for that reason."

"I would like to see them develop the ability to integrate with more AWS services."

"If they could make it cheaper, that would be something."

"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."

"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."

"I would like to see a Nagios monitoring plugin which watches the health and performance of the system. The only one available just checks volume capacity."

"I would rate this a seven out of ten because it's a good performance storage, but the price is a little bit high."

More Everpure FlashArray cons

"The implementation is complex, especially when using custom servers."

"Its licensing can be better. They can make it easier for us to scale our infrastructure."

"The GUI is not user-friendly for new users and has room for improvement."

"The initial setup is a little bit complex."

"The interface could be improved."

"For me, personally, it's a little bit slow because there's so much stuff in the underlying layers that even after talking with Nutanix support, I couldn't really grasp it."

"There is a feature in the product called Data Lens, and I can elaborate on its maturity. I believe this Data Lens feature could be enhanced from Nutanix's side."

"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."

"The documentation on the support site needs to be improved."

More Nutanix Unified Storage (NUS) cons

Pricing and Cost Advice

"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."

"Pure Storage FlashArray's pricing is very competitive."

"Pure Storage has not helped us to reduce our licensing costs."

"We have an Evergreen Storage subscription, which I think is a great feature."

"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."

"The price of the solution is not expensive."

"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."

"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."

Information not available

"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."

"It is competitive with other vendors, but you get more for your dollars. It is fairly priced, but not cheap."

"It's not the cheapest solution. It's in line with other solutions, but it offers features that the competitors don't have at any price point, especially with regard to analytics and ransomware prevention. No one else has any sort of object-based storage available. Nutanix Unified Storage is a lot more feature-rich. This is a situation where you get what you pay for."

"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."

"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."

"The product is pricey."

"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."

"It is very good. It is much more competitive than a dedicated storage platform."
