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.

Shared storage capabilities provide enterprise value with good reliability
Amazon FSx is more costly compared to other storage solutions like EBS or EFS. The auto-scaling feature should be improved, as it currently includes downtime. I need to manually increase the storage, which is not ideal. Integrating FSx with Windows Server is challenging; it's a long process involving Active Directory (AD) setup and synchronization.

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

"In Pure Storage FlashArray, the dedupe and compression are excellent, and performance is good too."
"The connections are a lot faster than what we had in the past. One InfiniBand does what we did on all of our Fibre Channels."
"Pure Storage FlashArray simplifies maintenance and management with its intuitive GUI, making storage allocation and other processes easy to understand, even for beginners."
"I recommend this solution for production because it has good performance and capacity management."
"Overall, Pure Storage FlashArray has never let us down in front of customers so far."
"We consume less physical storage because of the solution’s deduplication and compression."
"This solution is very scalable."
"Our clients see a reduction in total cost of ownership by around 40%."
"On a scale of one to ten, I would rate Amazon FSx a ten."
"The shared storage capability is highly valuable."
"FSx operates as an independent service, not tied to any server, which eliminates dependencies between applications for storage."
"I rate the stability of Amazon FSx ten out of ten."
"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."
"Nutanix Objects is reliable."
"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."
"Nutanix support deserves a rating of nine out of ten."
"The availability of the environment is incredible, and with Prism Central, you're able to diagnose and go over issues quickly."
"For customer service and technical support, I would rate them a nine out of ten."
"Since I started working with Nutanix, the only consistent thing I can identify as key is simplicity."
"Unified Storage's centralized management features enable us to accomplish whatever we want in terms of operations and migrations."
"The customer service executives of all Nutanix products are active and responsive."
 

Cons

"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"I would like to migrate to the cloud in the future and know how that would actually work with this product."
"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"I would rate this a seven out of ten because it's a good performance storage, but the price is a little bit high."
"The product should improve its response time. I have also encountered issues with its configuration."
"The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors."
"The technical support is okay, but could be improved."
"It would be good to have metrics of the box's performance so we can see what it delivers, but currently, I can't see what it's actually doing."
"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."
"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."
"A direct FTP feature would be beneficial instead of relying on transmission services."
"Areas for improvement in Nutanix Unified Storage (NUS) include more redundancy to ensure no data loss, and balancing the workloads is very important to maintain managed workloads throughout the year."
"The initial setup is a little bit complex."
"I would them to have more communication with other platforms, and it appears they are already doing that."
"There is potential to push this product more since it's not common in the market. They could increase their marketing efforts."
"A centralized file share permissions console might be useful for Nutanix Unified Storage (NUS). Getting in and directly managing permissions instead of using the snap-in from Windows itself might be something to consider, but that's a small thing."
"A more consistent flow of information would improve the solution, as I've noticed some inconsistencies, mostly stemming from the coordination between the hardware vendor and Nutanix."
"Nutanix Unified Storage (NUS) sits in a good place for us. The biggest improvement would be to make it more cost-effective from a storage node and storage perspective, so that the solution isn't such a question when it comes to cost-prohibitiveness versus potentially other vendors."
"Its licensing can be better. They can make it easier for us to scale our infrastructure."
 

Pricing and Cost Advice

"Pricing is very competitive, and it's better than other competitors."
"We have seen a reduction in total cost of ownership (TCO)."
"It is cost-effective because after buying a subscription, they provide a service to upgrade hardware for free. They are providing so many features. When you consider the features provided, it is cost-effective."
"You get what you pay for. It is expensive, but it really works."
"Pure is typically more expensive than everyone else. You get what you pay for, but I have lost deals to similar solutions because of pricing. They include everything, and that's another positive about Pure Storage. They aren't trying to nickel and dime their customers for different features. It is all included in one price. The license is by capacity, and the price depends on the capacity and the discount we're getting from the vendor. You get the SKU of the physical appliance, support, and maintenance, and that's it. You're licensed for whatever feature they offer. It is all rolled up into the price of the appliance."
"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."
"I have had a couple of customers who have complained about the cost. It can be a little more expensive than some of the other platforms. After it has been installed, I have never had a customer say, "I wish we wouldn't have spent all that extra money." They have always been happy with the product after it has been installed. They might be on the fence about it because of the price, but everybody who I have ever seen install it, they are always happy with it."
"We have an Evergreen Storage subscription, which I think is a great feature."
"The lowest price I have paid is $370 or $380 per month, while the highest can exceed $3,000 per month."
"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."
"I hope that it will stay the way it is. We have seen the changes in VMware and what happened to them. I have heard that Nutanix will raise the prices, but I hope that they will not do that."
"It is very good. It is much more competitive than a dedicated storage platform."
"The price of the license is expensive when comparing it to traditional storage."
"The solution's pricing is better compared to other products."
"While the price may not be the most affordable, I believe it offers good value for the benefits it provides."
"The solution is highly-priced."
"The pricing is fair."
