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

"I find two features of Pure Storage most valuable. The first is the "safe mode" function, and the second is its simplicity."
"The administration is very easy and quite minimal, the performance is very good, the installation is pretty straightforward, and technical support is good."
"This solution has improved our organization. In the past, we had reports that were taking up to two hours and after switching to SSD storage the overall processing power dropped to half an hour. The end users saw an immediate performance gain."
"The seamless integration into the public cloud has improved my organization."
"The best features of Pure Storage are their support and analytics."
"After switching to Everpure FlashArray, we saw significant results, as whatever hardware we used before is now compressed to 80%, maximizing space utilization in a single system."
"VMware has benefited our IT organization because we're 100% VMware, everything is running on it."
"It's very fast, easy to use, and the cloud-based management is good."
"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."
"Implementing this solution has been a very good decision for our in-house data center."
"The most valuable feature is the robustness, which is typical of IBM because their software generally just works."
"We can test even the most storage-performance-hungry workloads on our Nutanix blocks."
"The Nutanix customer service is outstanding and easily the best from all vendors we work with."
"The most valuable features of Nutanix Acropolis AOS are storage and hyper-converged. The solution is easy to use and the administration is very good."
"I would say that it's a simple to use product, it fits all sizes and it is budget-friendly."
"To receive a performance enhancement by merely clicking the one button upgrade is the true value of the platform and what I look forward to the most."
"Karbon is a must-have as it drastically simplifies the deployment of Kubernetes."
"Nutanix is a converged system with web-scale technology, and the technology is invisible to the IT department so you can focus on your business instead of making IT a problem in your organization."
"This solution is great for people who do not want to go with Acropolis or other VMs."
 

Cons

"The price is too high."
"The scalability of the solution is extremely costly."
"The support for NFS protocols right out-of-the-box need improvement. I'm used to other storage vendors who have NFS support right out-of-the-box, and Pure Storage doesn't seem to have anything."
"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."
"Awareness about Pure Storage needs to increase. Currently, people mostly think of Dell and NetApp when it comes to storage."
"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."
"We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client. The current plugin for Pure Storage doesn't show up in that client at all. You have to go and use the legacy FlexFlash client to see the Pure Storage plugin in vCenter."
"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."
"USB dongle-based licenses do not allow us to directly locate the USB ports on Nutanix."
"It would be fantastic if there was a built-in layer, in Nutanix, that acted like a cloud interface. So far, we need to integrate a cloud interface on top of Nutanix for billing the usage for specific customers' domains. It would be great if a cloud gateway was built-in, inside Nutanix."
"The look and feel of the web GUI of this system needs improvement, when compared to other systems. Its hardware integration also needs improvement."
"Nutanix has a complex infrastructure, we have customers that consider VMware instead. Additionally, the performance could be better."
"Nutanix Cloud Infrastructure's cloud platform management software could be improved so that I can manage my load between the cloud and on-premises."
"Nutanix needs to improve network features like Passthrough – SR-IOV. It could be improved by supporting SR-IOV, if they had that support, I would not have needed to implement the VMWare vSAN."
"Customer Service: It's excellent, but expensive. Technical Support: It's excellent, but expensive."
"We would like to see it support other systems outside of the compute stack from which it was built."
 

Pricing and Cost Advice

"The pricing of Pure Storage FlashArray is reasonable."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."
"The pricing is very attractive and it delivers performance for the money."
"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."
"When you are paying more than you were paying for the storage space, you'd like the cost to be less. If they could get into the spinning disk kind of cost, that would be it."
"It's priced higher than the market."
"If you are cost-sensitive then this solution is not for you."
"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."
"The price of Nutanix is lower than other products."
"I know Nutanix and VxRail have similar prices and licenses. Nutanix is a go-ahead if AHV is used as hypervisor because it is already embedded in the price."
"Pricing varies greatly between license and editions."
"If a customer has been using VMware, the difference in pricing is lower. However, if they are looking to use the VMware, the price can be much higher depending on the license."
"I don't feel that I am receiving the performance which I am paying for."
"There is a license required for this solution and my clients usually purchase a two-year license with extended support. The price of the solution could be reduced, it is more expensive than competitors."
"The price of the solution is high."
"This product is less expensive than some of the competing HCI solutions."
