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

"It is easy to manage. You don't have to have the same people who used to manage the Dell EMC arrays because the solution is more intuitive."
"It comes with a large number of features out-of-the-box, which makes it easy for us to see problems and manage capacity."
"Very efficient storage"
"It solved many problems and provided unexpected features that improved our business execution, making us more agile internally."
"Manageability is its most valuable feature; it is simplified storage, as we don't have to maintain or administer it on a daily basis, which is good, and we can depend on the solution's ability to phone home and leverage the built-in support function of the product."
"The code upgrades are very smooth."
"We were previously on legacy storage systems, and after moving to Pure Storage, our stability and performance both drastically improved."
"The most valuable feature of the Pure Storage Flash Array is the blazing fast monitoring."
"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."
"Right now, technology-wise, I feel Nutanix appears to have the simplicity side of things going for them."
"The snapshots, cloning, and replication are all effective in helping to reduce downtime. It can replicate cluster data for disaster recovery and it provides high availability in case a node or a disk fails."
"There are a lot of things I really like. Perhaps the best part is taking a snapshot of a virtual machine. It's very quick. Another useful part is replication and creating a protection domain: using the protection feature to replicate a machine to a remote site for DR purposes."
"Our environment is now consolidated into one solution, making it easier to get support because we no longer need to go to multiple vendors and can just have one point of contact."
"The most valuable feature is Move, which allows you to migrate virtual machines from VM to AHV."
"They have one of the best technical supports in my experience."
"It has solid performance and provides data locality."
"The solution has single-window management, the ability to create VMs and monitor their usage on the fly, and the ability to add more resources if required."
 

Cons

"We would like more extended historical data to help with some of the capacity planning. This is something that we are asking for all the time. E.g., what was the historical performance of this particular volume? So, we would like more historicals."
"There is not a great need for improvement, but better pricing could be beneficial."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"The main disadvantage of Pure Storage FlashArray is the price."
"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."
"The price of this solution is high and should be lowered."
"The price of this solution could be improved."
"Larger capacity and more storage ports would be the two things I'd like to see."
"The reporting mechanisms need improvement."
"The interface is not user-friendly so the ease of use could be improved."
"In the licensing, it needs to be clear about features because it is not clear whether Flow is integrated or not."
"It has the ability to connect to Azure or AWS for storing backups. I would like to have the capability to spin up a backup on Azure or AWS for disaster recovery purposes."
"I would enjoy an advanced mode where experienced users can leverage their knowledge to do advanced things currently only allowed using the command line tools on the CVM."
"Site-to-site replication needs some work."
"When we have issues with the solution, they tend to be around networking."
"Pricing and licensing are definitely not cheap, but not bad either."
"Areas for improvement would be the memory setting and the CPU setting reserve features, which are not available on Acropolis. I also feel that the DR solution, the reporting, and the component that is combined with the Nutanix OSP need to be improved."
"Nutanix marketing strategy needs improvement, particularly in Myanmar."
 

Pricing and Cost Advice

"Its price is almost double than any other flash storage solution."
"All storage is expensive so any price improvement would help."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"I would prefer that they lower their pricing."
"It's priced higher than the market."
"The pricing of Pure Storage FlashArray is reasonable."
"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"There are no licensing fees aside from the support."
"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."
"Their technical support is really good. They have been very helpful."
"Nutanix Cloud Infrastructure could be cheaper. It's costly to upgrade the solution. There are no additional costs aside from the license."
"The price of the solution is high."
"Its price is fine. I can't really complain about that."
"Nutanix is cheaper than Cisco HyperFlex, although it depends on the configuration because Nutanix can also be expensive."
"Our Nutanix license is for five years. There is a support arrangement there, but that aspect is more or less taken care of during the initial installation. With HCI architecture, whenever we do any kind of auto scaling or scaling of servers and resources, there is a significant amount of software licensing involved."
"It is slightly more expensive compared to a standard, on-prem, bare-metal configuration. There is about a 30 percent overhead there."
"The cost of Nutanix Acropolis AOS is reasonable."
