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

"Pure Storage FlashArray has helped us to improve the reporting and the billing cycle."
"Pure Storage technology allowed us to automate tasks, reducing something which started as a 12-hour turnaround down to about 15 minutes."
"I like its speed. It has all the features that I need."
"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 helps us maintain uptime much better than other solutions we've used in the past, and the support is extremely quick and responsive."
"The biggest return on investment for us is not having to do a swap out of the arrays every five years."
"The initial setup was very straightforward and very quick. It was up and running in our data center within 24 hours of receiving it."
"It releases those to new teams within minutes at a very small storage cost amount."
"On a scale of one to ten, I would rate Amazon FSx a ten."
"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."
"The shared storage capability is highly valuable."
"My experience with pricing, setup costs, and licensing of Nutanix Unified Storage (NUS) is that compared to other vendors, Nutanix is very reasonable."
"I see that Nutanix helps to reduce the total cost of ownership in general."
"We have virtually zero downtime with Nutanix. It updates itself, and we can easily move machines from one cluster to another."
"One of the main features of Nutanix Unified Storage (NUS) that I find most valuable is the flexibility and scalability of it, as well as the ability to perform replication for our Disaster Recovery environment."
"The product is good, easy to upgrade, easy to use, and user-friendly."

Cons

"Pure Storage can improve FlashArray by providing more logging visibility to customers. Currently, there is no log visibility."
"Technical support needs improvement. With respect to them being able to respond, they're more marketing people, less technical."
"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."
"I would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side."
"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."
"Pure Storage had operational challenges between 2016 to 2018, impacting perceived reliability."
"Pure Storage FlashArray has not helped decrease the total cost of ownership."
"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."
"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
"A direct FTP feature would be beneficial instead of relying on transmission services."
"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."
"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."
"The product does not offer one console."
"The licensing terms are restrictive, as they go by terabyte cost."
"One area for improvement I noticed while using Nutanix Unified Storage (NUS) is expanding advanced analytics and predictive capacity planning capabilities to help administrators make even better long-term storage decisions."
"According to the keynotes announced by Nutanix the previous day or this morning, the data storage for Kubernetes requires improvement as it has a few shortcomings in the area of operations."
"Its features can be further enhanced from the DR and high availability points of view to match other vendors, such as NetApp. It has snapshot, replication, high availability, and other data and storage-level replication, but there are some limitations."
"Customer service is more difficult to call and they do not responding as much as, for example, DataCore. It's not the same level of satisfaction compared to DataCore. Responses could be faster."
"The integration feature with Nutanix Unified Storage (NUS) could be improved, maybe into a more stabilized version."
"I have heard that there have been latency problems."
 

Pricing and Cost Advice

"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."
"The price is very reasonable when compared to other solutions."
"We purchased a license to use this solution and we pay for the storage ourselves."
"We do not incur additional costs beyond the licensing fee."
"The cost of Pure Storage is subjective and determined by your environment. Pure Storage tends to be more expensive than NetApp, but it is cheaper than EMC. Performance varies with data workload, making cost considerations complex."
"Pure Storage FlashArray is expensive."
"There are no licensing fees or other costs."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"The lowest price I have paid is $370 or $380 per month, while the highest can exceed $3,000 per month."
"It's competitive and attractive for moving things to it and then prioritizing those newly freed up resources for something else."
"The solution's pricing is better compared to other products."
"The product has an annual licensing fee."
"The price of the license is expensive when comparing it to traditional storage."
"The pricing is a bit too high."
"The licensing currently works based on a software license. If we have files, volumes, and other licenses combined, that would be more valuable. I don't want to go for a separate license for files and a separate license for volumes. We have unified storage, so the licensing should also be unified. That would be helpful."
"While the price may not be the most affordable, I believe it offers good value for the benefits it provides."
"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."
