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.

A robust solution with good performance and support
This is a solution that scales well, although I think that we have stabilized in terms of use. With respect to scalability, we have an open question as to whether we will be able to grow into a cloud-based deployment. We don't know in what ways this solution will assist us with the migration, or whether we can still use it for DR. We don't know about the type of backup, be it full, incremental, or otherwise. We are also looking for a cost-savings if we migrate. These are things that we will find out over time. We have about two petabytes of data.

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

"We chose Pure Storage because it had the best performance of all the products that we tested."
"Pure Storage has been the go-to storage array for me; it's a lot smaller, easier to set up, faster to upgrade, more reliable, and the performance is very stable."
"If you need a high-performance storage appliance that is easy to install and maintain, you pretty much can't go wrong."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"We actually originally went with a competitor's product, and after about eight months, a lot of wrangling, had them buy it back from us, and then we bought a similar Pure Storage product, and it's just been great."
"The simplicity of it. The performance is good, but the simplicity is the best thing. Storage management is quite complex, but Pure Storage is easy to manage."
"Our clients see a reduction in total cost of ownership by around 40%."
"It overperforms both in terms of storage capacity and throughput, and bandwidth capability."
"The ease of use is the solution's most valuable aspect; it's very user-friendly, and the security on the product is very good."
"The most valuable feature is the robustness, which is typical of IBM because their software generally just works."
"Implementing this solution has been a very good decision for our in-house data center."
"The stability is good. This is the number-one product in that regard."
"Acropolis AOS's networking concept is excellent."
"This is a very flexible solution that you are able to run however you want."
"If you are looking for a computer, power, networking and storage solution, this is a great option."
"The most valuable features are the user-friendly dashboard and that we don't need to move resources manually when adding new nodes into running clusters."
"One of the most valuable features is the One-Click Upgrade. When I need to update the system, I do it with one click. This product is amazing because everything is easy to manage, from network management to snapshots."
"The most valuable feature I have found to be the Acropolis Hypervisor (AHV)."
"The machines provisioning times have reduced drastically."
 

Cons

"The solution is not cheap. It's much more expensive than DataCore."
"In terms of improvement, Everpure FlashArray could have more attractive UI/UX design compared to other solutions."
"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."
"They have a product, FlashBlade, which is their object storage integration, and that's something that we haven't integrated with yet. This might be an area for additional focus as it would play into scalability, because the very nature of object storage is that it's infinitely scalable."
"The scalability of the solution is extremely costly."
"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"Once, before Pure went public, we were a member of their customer advisory board and beta tested replication. One requested enhancement yet to manifest is the scheduling of snapshot replications."
"The reporting mechanisms need improvement."
"The interface is not user-friendly so the ease of use could be improved."
"The solution does not lend support when we connect with a few dongle licenses."
"Nutanix has a complex infrastructure, we have customers that consider VMware instead. Additionally, the performance could be better."
"We ran into an issue as a managed service provider because Acropolis isn't designed to be used the way we are running it."
"It would be great if they could improve the GUI features."
"While their overall Nutanix Bible is good, they are lacking good descriptions for particular scenarios that might be helpful to many users."
"In Thailand, there really isn't a cloud version of Nutanx available to us."
"The process of migrating from old hardware to new could improve."
"I rate it a nine out of 10 because I think there is still room for improvement on the price."
 

Pricing and Cost Advice

"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."
"In terms of other contemporary arrays, Pure is something you need to have a use case for, as it's not priced for you to buy one off-the-shelf. If you have a use case, heavy lift Oracle Databases, any type of noticeable virtual desktop infrastructure (VDI), or need low latency and high throughput, you should consider all-flash at least and probably Pure Storage."
"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."
"I would prefer that they lower their pricing."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"Pure has been flexible with us on the pricing models."
"My organization has a yearly license, but I believe that Pure Storage FlashArray has capacity-based licenses as well. I'm definitely happy with the pricing."
"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."
"For a database, on a yearly basis, we pay approximately $3,500 for licensing fees. The solution is sold as a subscription on a yearly basis so there are no other ancillary costs."
"If you are cost-sensitive then this solution is not for you."
"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 price of the solution could improve. Nutanix has recently changed its pricing model from perpetual to subscription. They have identified there are challenges with the pricing model."
"Reconsidering the licensing packages could reduce the price, especially for companies that may not need all the bells and whistles. Many of the features are based on open-source software, so there's potential to offer more flexible pricing options. Additionally, with the right expertise, companies could potentially create similar environments themselves, reducing the need for extensive support and licensing costs. I rate its pricing a six out of ten. The tool costs around 300,000 dollars per year."
"They offer multiple tier licensing which means that lower level licensing will have less features."
"The price of the solution is high."
"I don't feel that I am receiving the performance which I am paying for."
"Nutanix Cloud Infrastructure's pricing is higher now."
"My advice is to get the ultimate license, as it is worth it."
