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.

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.

Meets our customers' needs but they should move towards high-level scaling

I the product already has scalability features, but in terms of size maybe they could do more to work with parent storage and move to high-level scaling. That area, I feel, is a place where there could be some more options in this solution. It would be a way to improve the scalability in another direction, maybe options to scale out rather than just up. So far we have done very few installations. So maybe in the coming days, weeks and months, we would be able to come up with some additional features that are needed, but right now the product has the competitive features that our clients need.

Quotes from Members

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

Pros

"This storage has to be the most well thought out and effective storage that I have had the privilege to work with."

"It saved a lot of space, as far as physical space in our data center."

"It does everything they say it will do: It's very cost-effective compared to other big players, integrates very well with VMware, is tiny so we're saving power and space in the data center, and it's really easy for us to manage."

"After installing Pure, the processes that would take 40 minutes to two hours to complete are now done in five minutes."

"It has good stability for our company."

"The compression and deduplication features help to make the best use of the capacity."

"The biggest lesson that I have learned from using Pure FlashArray is that it's user-friendly, easy to manage, and very flexible."

"If you're interested in using this solution, I recommend that you do the same — see if you like it."

More Everpure FlashArray pros

"One of the major things is that Nutanix allows you to move from VMware to Acropolis and it also allows you to move back."

"The most valuable aspect of Nutanix is the performance of the storage, which is excellent. And controlling compute, storage, the network, and security all together in one box is very efficient for us. It gives us a single platform to manage our all infrastructure."

"My advice to anyone considering Nutanix Acropolis AOS is that you won't go wrong."

"Technical support is 10/10."

"We have had good feedback from our customers about this solution."

"The solution is much faster, the performance is very good - much better than VMware, and it's much easier and faster even when you want to create a server from a template or clone."

"The solution offers impressive performance."

"The pricing is pretty good."

More Nutanix Cloud Infrastructure (NCI) pros

"Automatic rebalancing is the feature saving administration time, and also auto rebuilding."

"Comparing other products that are competing with Dell EMC (Enhanced Memory Controller), Dell seems to us to always come out on the high-side."

"The ScaleIO UI: EMC has been working with storage for a long time; therefore, they know how to clearly present any important data, including data flow and each drive's IOPS/bandwidth, and allow the user to easily monitor bottlenecks and problems, especially the rebuild and rebalance status of child objects."

"We are using it as the primary virtualization storage (both for internal corporate users and external customers) for VMware and Hyper-V virtualization platforms."

Cons

"Reports of performance and LUN utilization could be improved."

"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."

"Everpure FlashArray can be improved as the pricing is expensive, but you do get what you pay for; you are paying a premium for better service, better warranties, less downtime, and other things, so I do not know that a lower price would work out because you probably would not have that high of quality for those things."

"The only issue is the pricing. Because we have competition, our customers always take another brand and say they can save their investment."

"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."

"A noticeable area for improvement is the support for object storage. The FlashArray does not natively support object storage like S3 or Swift, which pushes customers needing these features towards the more expensive FlashBlade."

"I would like to see box-to-box encryption on replication included in the next release."

"Based on my experience with various technologies like EMC, NetApp, and Pure Storage, one area for improvement is compliance certifications. NetApp excels in this area, particularly in the American Army or defense sector, where NetApp has approval, whereas others are striving to achieve the same. NetApp also delivers security, ransomware protection, and scale-up capabilities more effectively."

More Everpure FlashArray cons

"Some of the features in the user interface can only be accessed through the command-line interface."

"We could always use a performance upgrade, or simplified management."

"It is a CentOS-based operating system, but CentOS releases security patches almost every week or every other week. However, Nutanix releases their upgrade at three or four month intervals."

"Coming from a XenServer environment, I would like better integration of XenServer into the AOS and Prism Central."

"Deployment could be more user-friendly - currently, it requires certain skills with the network and nodes."

"One of the improvements I would like to have is related to naming. It is getting confusing because they are using three-letter acronyms, which are more or less misleading. What I do not like is that they changed names and reused names. They had a meaning in the past and they are still using the names for something similar."

"The initial setup can be a bit difficult."

"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."

More Nutanix Cloud Infrastructure (NCI) cons

"There is room for improvement in the area of horizontal scaling."

"If they could introduce a write cache feature, the product would be perfect overall."

"I think ScaleIO already has some features for scalability as it is part of the reason for the product, but in terms of size, maybe they should try to address parent storage."

"It would be nice to set minimum IOPS per volume, besides just the maximum, to be able to satisfy this demand from customers out-of-the-box, not by calculating number of disks, etc."

"Ecosystem around the product: There is no built-in system for viewing history data, such as volume IOPS. We have to provide graphing by Prometheus and Grafana, which would be a good new feature in ScaleIO."

Pricing and Cost Advice

"While it comes with a higher price tag, this investment often translates to significant improvements in performance."

"The price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."

"It's a good price point and it's a solid product for the price."

"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."

"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."

"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..."

"Pure Storage has not helped to reduce our HANA licensing costs."

"The pricing is very attractive and it delivers performance for the money."

More Everpure FlashArray pricing and cost advice

"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."

"We got the renewal done recently, and there was no cost involved."

"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."

"The one disadvantage is relative, financially Nutanix Acropolis AOS is a little bit more expensive than the old solution."

"Nutanix Cloud Infrastructure is expensive."

"This product is less expensive than some of the competing HCI solutions."

"I think it's cheaper than VMware in terms of cost."

"Nutanix Cloud Infrastructure's core licensing needs to have an upper limit since processors are coming out with incredible numbers of cores on them."
