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.

Has optimized performance using cluster deployment and distributed file access but needs better visibility into network dependencies
IBM Spectrum Scale being software-based storage allows users to utilize any hardware supported or defined by IBM without dependency on physical hardware provided by IBM. This is one of the features I appreciate most because if you have existing infrastructure at your site but don't want to reinvest in hardware, you can purchase IBM Spectrum Scale software and deploy it as software-defined storage. Users can comfortably access data from their host to the storage host without relying on new network setup when deploying GPFS as it uses the existing corporate network. However, high-speed ethernet network is required. By adding switches to the same network where client hosts reside and deploying GPFS storage array, any file system created on the storage cluster can grant export permissions determining which hosts can access specific file systems. These hosts can directly mount them as remote file systems. The process is simpler compared to defining IQN for providing access to client hosts. Creating a cluster for clients with virtual machines or physical Linux/Windows machines requires installing GPFS services on client nodes, which creates a client cluster. Access is defined on the storage cluster for the particular client cluster, allowing all hosts in that client cluster to mount file systems with granted permissions.

Hyper-converged storage has improved performance and now supports high redundancy for our VMs
Nutanix Cloud Infrastructure (NCI) was transparent because we were on a regular infrastructure before. We went on NCI and were able to improve performance, but it did not really change how things worked. The performance was really better for applications and access times to the data. I regularly looked at the analytics to see what was going on in my servers and what it was saying to optimize performance. It was pretty interesting because it could analyze and give insights on how to get things working better. In the latest versions, the Prism interface has been replaced by Prism Central. This requires another machine to be deployed to manage the servers.

Quotes from Members

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

Pros

"Technical support is very good."
"It has been quite satisfactory in performance and scalability."
"It simplifies storage."
"We chose Pure Storage because it had the best performance of all the products that we tested."
"We saw a vast improvement when we switched over to using the Pure Storage model over the XtremIO."
"Support has been helpful."
"I have never experienced an outage with the product or had any support that was below excellent."
"FlashArray's data reduction and NAS features are incredible. Its performance is the best I've worked with."
"There is nothing else that even compares to Spectrum Scale."
"Technical support has been very helpful, and they provide us with pretty good solutions that we can implement moving forward."
"It has been pretty reliable throughout the years. As far as capacity is concerned, it can handle most heavy loads."
"Spectrum Scale is one of the most important products in our environment now."
"We use it for our data over multiple systems, and at the same time it is a shared file system that works pretty well for the most part."
"Allows us to share files across multiple environments."
"We are using it for monitoring all of our storage."
"It is incredibly scalable; you can add more storage to it, add more file sets, and add it to more servers, making it a robust product that should be able to expand with us."
"Nutanix does a superb job with technical support."
"We now increase the capacity of our datacenter without having to add more square footage, while increasing its horsepower, allowing us to run more servers utilizing less space than before."
"The technical support on offer is the best part of the product; they are excellent and we are extremely satisfied with their level of service."
"It is 100% stable. It's the most stable infrastructure that we have."
"We went on Nutanix Cloud Infrastructure (NCI) and were able to improve performance, but it did not really change how things worked."
"With Nutanix, we saved a lot of money due to that new technology."
"Compression, deduplication, and erasure coding have improved storage usage by almost three times."
"My experience with the Nutanix Acropolis is good from both a reseller and end-user experience."
 

Cons

"The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors."
"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"They should work on their upgrades, they're not smooth."
"For large storage needs, it is expensive."
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"I would prefer that they lower their pricing."
"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."
"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."
"We do not feel as a company that the product can grow with us anymore, so we are not going to use it anymore."
"Maybe it needs integration with HA."
"I wish there were some graphical user interface to access the GPFS file system creation and monitoring."
"We do have some issues where Spectrum Scale does not work as expected. We have seen our Spectrum Scale servers go down unexpectedly, but because we have a cluster, it does not take out the entire organization."
"Initially, stability was a concern as we encountered numerous issues and errors."
"The solution's pricing could be better."
"Integration with other vendors is not available. This feature would be very helpful."
"Notifications could be improved as they're not currently very useful."
"Nutanix Cloud Infrastructure lacks compatibility with certain older processors."
"We feel that the cost for capacity is still more expensive compared to other solutions."
"It is small but complex."
"The licenses for Nutanix are very complicated."
"I would like to see more Kubernetes and container-related workflows and multiple cloud-partner management. I would also like to see how they will synergize all these AI/ML functionalities that are available on other platforms."
"From an administration perspective, the software's pretty big; it would be great if they could add more features and API integrations to the higher-level products."
"For these types of workloads, we realized the solution doesn’t seem to fit well, leaving many of the requests either being dropped or transmission lost."
 

Pricing and Cost Advice

"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 do not incur additional costs beyond the licensing fee."
"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"Pure has been flexible with us on the pricing models."
"The pricing is reasonable."
"Our costs are around $100,000."
"The solution is costly but reliable."
"The licensing is based on the number of terabytes."
"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."
"Nutanix Acropolis AOS is affordable, it has good value. The final price depends a lot on the hardware used, it's an appliance in the end. Whether you use HPE as the hardware vendor or Supermicro as the hardware vendor, it really depends on what hardware is used which is the main cost."
"The solution is quite expensive."
"Our licensing fee on the total setup up was about R900 000."
"In terms of the solution's licensing, it's quite comprehensive."
"My advice is to get the ultimate license, as it is worth it."
"Its licensing model is easy, but the bad thing is that we need to pay for the whole capacity at once. With VMware vSAN, we only have to pay for the capacity that we are using, which is not the case with Nutanix. So, we have more overhead for the licensing cost with Nutanix."
"The basic license that comes with the box allows basic virtualization features but advanced automation features would require an upgrade of licenses."
"Setup cost is minor, pricing is quite a bit (we have a 7-node-cluster for about 450K EUR with 2 vGPU-nodes for Citrix) but that includes hardware, software, and support."
