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

"The predictive performance analytics are good."
"The snapshot feature is valuable. It protects data based on the policy."
"We find the ease of usability and setup valuable."
"My advice to people who want to implement Pure Storage FlashArray is that it's a good NVMe solution, has a lower response time, and also good for entry-level storage purposes, e.g. small offices, small to medium-sized business, etc."
"It is very easy to use."
"It helps to simplify storage. For most of our customers, when they move to Pure Storage, storage becomes an afterthought."
"One of the features that my customers are really interested in is immutable snapshots. There are immutable snapshots to which your applications can be reverted back if you are hit by some kind of ransomware threat or malicious attack. That's kind of a key deal, and it is one of the selling points I use to point out to my customers the value and the features that Pure Storage brings to the table."
"The most valuable features of Pure Storage FlashArray are simplicity, ease of use, and dashboard management."
"Implementing this solution has been a very good decision for our in-house data center."
"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."
"The most valuable feature is the integration of all parts in Prism Element, the browser-based management tool."
"In addition to the hyper-converged infrastructure, most of our clients are pleased with Acropolis' built-in replication in terms of the DR setup. Our clients also like Prism Central's advanced management and analytics, and many find Nutanix Flow and playbooks incredibly useful."
"Pricing is a little high but if you really look into what the product provides, the cost saving on setting up infrastructure and maintaining it is greatly reduced."
"The solution offers impressive performance."
"The initial setup was quite straightforward."
"We have had good feedback from our customers about this solution."
"We really love the Lifecycle manager and one-click upgrades."
"It's the only solution that can scale properly — there is no limitation on the number of nodes that a customer can have in the same cluster."
 

Cons

"The latest release contains bugs that shouldn't be in a production environment. Two incidents impacted our client, including hardware-related bugs. They need to be more cautious in testing before they release."
"The way Pure Storage does the controller storage warranty or replacement has been an issue for some people who just replace the controllers every couple of years, and that's where some of the confusion with pricing and support has come in. They should be clear on the way the controller replacements happen, as it is important to know whether or not you can get a good return on them, because it can be a little confusing."
"Pure Storage support could be a little better."
"Pure will probably have to move to other layers of the stack, not only storage but, maybe, hyperconverged."
"It was not proactive communication."
"I would not say anything because we still do not use Everpure FlashArray fully."
"It's not so scalable. It's got moderate scaling capabilities right now. The clustering technology needs a bit of work, they need to improve that."
"The 3PAR SSD arrays that we have are still failing a lot so even though we're under warranty, we still have to get someone out and usually have someone troubleshoot so that usually adds onto the cost. With Pure, we've had a disc fail and we pop it out and you pop it in and it's good to go."
"The reporting mechanisms need improvement."
"The interface is not user-friendly so the ease of use could be improved."
"The One-Click Upgrade process could/should offer the ability to integrate with 3rd party drivers. For example, we use NVIDIA Grid graphics cards. It would be amazing if, during the One-Click Upgrade process, we could "slipstream" additional VIB drivers for ESXi into the upgrade process."
"The cost of the solution is too expensive. There are other options, such as VMware, that are offered for less money. In Latin America, it seems to be overpriced for the market."
"I believe the only things that may need to improve is that the Nutanix Controller VM consumes quite a lot of resources."
"This solution offers excellent functionality but could use a stronger interface."
"The software-defined networking should be improved. It is quite substandard as compared to the VMware variant."
"One disadvantage of Nutanix Acropolis AOS is it doesn't support external storage. Connecting external SAN storage to Nutanix, it's not supported."
"I'm sure there are a lot of things that could be improved, but I'm actually very satisfied with this product. There may be some possibilities to move the virtual server dismounting points or to move the server from one group to another, but I can't think of any special improvements or update features."
"Could have better visibility with the main OEM backup integrators."
 

Pricing and Cost Advice

"We feel that the pricing is fair and the licensing process was easy for both."
"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."
"We evaluated Oracle and Hitachi, but Pure Storage had the better pricing."
"It could always be lower, but it's okay."
"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."
"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."
"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."
"The Evergreen Storage subscription is a really cool concept. As long as we maintain our subscription, we will get new controllers every three years and really never have a forklift upgrade like we currently are doing. Just that future-proofing is an ease off of my mind to know that I won't have to do what I'm dong right now again."
"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."
"The solution is quite 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."
"In terms of the solution's licensing, it's quite comprehensive."
"It is not cheap, but if you look at the return on investment and the total cost of ownership, it is worth the price."
"I don't feel that I am receiving the performance which I am paying for."
"Nutanix Cloud Infrastructure's pricing is higher now."
"Our licensing fee on the total setup up was about R900 000."
"Our customers are on three years license to use Nutanix Acropolis AOS. The price of the solution includes all features and support."
