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.

Replication and dashboard improve system integration efficiency
It's a good product, but the implementation with the new systems is done via the cloud dashboard from HPE. I can't activate the system without a cloud connection, which is a bit laggy if I don't have the right firewall settings, making it take longer to implement the storage. It was better with the old systems, where I could install and activate without cloud connectivity.

A solution with a simple configuration and good stability but it's quite expensive
Access to technical support should be improved for our region. Technical support is good, but they're very hard to access. When we have a problem with this storage, it's usually related to a very bad configuration. All-Flash Storage is very, very expensive. They are important solutions so I don't really have any ideas about how to rectify this. The device could use better monitoring tools.

Quotes from Members

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

Pros

"What I appreciate most about Everpure FlashArray is that it performs compression and deduplication fantastically."
"It makes things ten times easier."
"Lone segmentation is simpler and more agile. It's improved the velocity in overall provisioning from project to operation."
"Pure Storage FlashArray offers numerous valuable features, such as low latency and high throughput."
"At this point, I don't know anything that they could provide in a better way."
"This solution is very scalable."
"Scalability is one of the best features. You can quickly add more. You can swap out the drives with larger sizes, you can add more shelves. All of that is perfect - the whole concept of keeping it modular..."
"The speed is the most valuable feature, along with the ease of getting it connected. We were able to get it online in less than a day."
"HPE Nimble Storage is very stable and performs well."
"With our previous storage product, I would probably spend 2-4 hours a week managing it, logging, checking on things, and fixing issues, and since we've switched to Nimble, I probably spend an hour a month doing various maintenance tests, which has greatly reduced the amount of handling that our storage requires."
"The deployment is fast."
"The SAN has been great, it has been a big help."
"They do a good job of helping people do storage in a very simple way."
"Support is superb, InfoSight with VM Vision gives us in-depth knowledge, setup and management are easy without needing storage experts, and performance delivers on all that it promises."
"The return on investment for us has been a tremendous asset."
"HPE Nimble Storage has helped our customers and has saved them money for the future."
"Implementation of the solution is very simple."
"Logic/software management"
"From my perspective, it is a huge success fulfilling everything we needed and more!"
"So coupled with the simplicity, performance, and just absolute ease of use of the management of it, I don't know why anyone wouldn't buy it."
"Using snapshots allows us to automate production database refreshes to development environments in minutes, rather than in hours."
"The stability of the solution is very good."
"Ease of use: My installers - my administrators over the system - they love how easy and fast it is to install and spin up a LUN and get going."
"The GUI is very straightforward and easy to use."
 

Cons

"With the introduction of Albireo technology and 81x data de-duplication reduction, Pure Storage better start looking at more effective de-duplication techniques."
"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 scalability of the solution is not as good as it probably could be."
"From a scalability perspective, it is a very small storage solution, so it's not very expandable."
"When creating a support case, visibility should be extended to others involved in assisting."
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."
"The backend of this solution utilizes an Active/Passive architecture, rather than an Active/Active architecture, which is a disadvantage, when compared to some of its competitors. Its storage capacity should be expanded in the next release."
"The solution that I have is a hybrid, not a full flash. The hybrid version could be improved."
"The product is near perfect, but there is always room for further development; maybe, more automation in snapshot management."
"The only drawback I find is the size of the components."
"Pure Storages have some option, which allows us the ability to directly download that host inventory and volume report. We can receive everything directly generated from the storage itself. We do not need to use some other web browser or something. If HPE Nimble Storage could do the same it would be a benefit."
"The solution could improve by having more granularity. For example, having the ability to go deeper into specific IO channels or specific latency issues that can happen would be a benefit. HPE has this ability on their side but it would be useful to have it on our side."
"HPE Nimble Storage provides only SAN-based storage and does not support NAS-based storage."
"The large hardware components may be difficult to fit into some standard racks."
"The resellers did the implementation of the solution, we did not do it ourselves. We have ten people for the deployment of the solution."
"There are some mid-market SMB customers that it may not fit the best for from a pricing perspective, but for the vast majority of our customers, once we aware of it and learned about the technology which it performed with, it fits a very useful metric."
"I would like them to improve the look of the product’s external casing and shelves."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"I would love to see capacity on its DRAM. I know it's not cost effective for them to do it, but I think that it could be a big differentiator and was a big differentiator from the beginning."
"The management graphical interface needs more improvement."
"I would like them to come down in price."
"There are a few areas where the system could be improved. Examples would be that the system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."
"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."
 

Pricing and Cost Advice

"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."
"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."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"We purchased a license to use this solution and we pay for the storage ourselves."
"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."
"The pricing of Pure Storage FlashArray is reasonable."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"The best features come included without any additional cost."
"The pricing is better than some of the competitors, such as Dell EMC."
"It is very pricey. You pay for what you get, and this storage solution is great. It is well worth the cost."
"I would classify it as an expensive product."
"There is a monthly fee to use the solution."
"The price of HPE Nimble Storage is good."
"Our hybrid solution could do with some more competitive pricing and more scaled-down deployments. Already, the smallest one is too much for us. We would flourish by having a smaller unit."
"The solution is a little pricey compared to others on the market."
"I believe the array, maintenance, and everything totaled around $140,000 dollars."
"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."
"Licensing is very straightforward. The cost was considerably lower than other products we looked at."
"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."
"The licensing is all-inclusive."
"Kaminario is very competitive on price. They also have a pay per TB model."
"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."
"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."
