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 solution is very scalable."

"The stability is perfect, the reliability is 100%, and the latency is always lower than 1 millisecond."

"Whoever is using Pure Storage is happy with it, including the latency and everything, and we have not received any complaints related to Pure Storage throughout the four years I have worked here, which is really great."

"What I like most about this solution, is the speed, resiliency and scalability."

"It solved many problems and provided unexpected features that improved our business execution, making us more agile internally."

"The connections are a lot faster than what we had in the past. One InfiniBand does what we did on all of our Fibre Channels."

"The technical support from Pure Storage FlashArray is perfect; if we have some trouble or we need to change something, we ask for support and they are helpful and answer immediately."

"The first set up we had was really straight forward and simple."

More Everpure FlashArray pros

"With Nutanix, we saved a lot of money due to that new technology."

"The administration console, automation, and the first cluster are all valuable features."

"It allows us to have a cloud-based ecosystem."

"Ability to create multiple VMs."

"The architecture of Nutanix is the best, and the virtualization we get, out of the box, is an advantage. Also, dedupe and compression are done natively, inside the platform, so there are no additional licenses. That adds value to it."

"A great feature involves real-time hardware changes."

"The stability of the product is excellent."

"One of the main features of the solution is that it works on many hypervisors. It is a big advantage. Additionally, the solution is compatible with VMware and Hyper-V, and the management interface, which is called Prism, is very intuitive and user-friendly."

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

"I would love to see a true one click upgrade solution."

"The price is too high."

"Technical support needs improvement. With respect to them being able to respond, they're more marketing people, less technical."

"The initial setup was a little complex. We had some initial issues with the design and had to help correct some of the white papers for it, but it wasn't your standard use case."

"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 would like to see more development on their Copy Automation Tool (CAT) for Oracle, as well as better integration for our customers running Oracle VM."

"Organizations with security concerns that prevent cloud utilization would benefit from a wider range of instruments available for offline operation. Currently, the limited selection of on-premise instruments hinders Pure Storage FlashArray's ability to compete effectively with other vendors."

"They can also include file services such as NAS shares and CIFS shares. There should be provisioning of the file shares from a unified array."

More Everpure FlashArray cons

"Nutanix now supports four hypervisors but they are not all at feature parity."

"Customer Service: It's excellent, but expensive. Technical Support: It's excellent, but expensive."

"Nutanix licensing and pricing is premium compared to other hyperconverged infrastructure vendors."

"The access speed needs to be improved."

"We ran into an issue as a managed service provider because Acropolis isn't designed to be used the way we are running it."

"Sometimes, I had to install it twice to place the solution."

"We did have some integration issues. We did have a problem with a Veeam integration."

"Given all the amazing features, there is room for improvement around the support ability of different hypervisors."

More Nutanix Cloud Infrastructure (NCI) cons

"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."

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

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

"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."

"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

"I don't know the exact cost but it's around $1,000."

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

"Because the price is a bit higher than other products, the data reduction equalizes the price with amount of the data reduction."

"It is cheaper than NetApp."

"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."

"We have seen a reduction in TCO."

"The pricing is reasonable."

"Cost-wise, it's been very effective."

More Everpure FlashArray pricing and cost advice

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

"The setup cost, pricing, and licensing are very competitive and TCO is very low compared to three-tier solutions."

"Nutanix price is high because it bundles all the components into single deals rather than allowing you to select the features that you want/will use."

"It is not cheap, but if you look at the return on investment and the total cost of ownership, it is worth the price."

"It's a cost-effective solution"

"Our licensing fee on the total setup up was about R900 000."

"The price of Nutanix is lower than other products."

"The basic license that comes with the box allows basic virtualization features but advanced automation features would require an upgrade of licenses."
