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

"The best features Everpure FlashArray offers are its ease of setup and incredible performance, which is better than most other software or hardware that we have used."
"Pure Storage has the right business model and will be around for a long time."
"After moving to Pure Storage, I have noticed that our databases are considerably faster and our performance has improved by at least four times."
"All our junior partners can administer the storage arrays. It is simple and easy to use. We don't have to dedicate a whole team of full time people to work on it."
"The performance is great."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"The most valuable feature of this solution is the support."
"They can provide a lot of performance, so there is not a lot of difference, but efficiency is something customers value because the compression can be up to twice of the second competitor."
"Very efficient adaptive flash technology: Even without having hundreds of rotating disks like we had in our former SAN system or having to buy all-flash storage, we get predictable and low latency numbers for all of our storage systems."
"Our upgrades are seamless. Whether we're adding storage, or upgrading the software, we don't take an outage for those upgrades."
"The most valuable features are ease of administration, stability, performance and customer support."
"Scalability is another reason we chose to go with Nimble: upgrading to another storage array. If we need higher capacity or throughput, we can just replace controllers, we don't have to replace or forklift-upgrade the whole chassis."
"Our virtual admins are able to take control of Nimble and know how to allocate the storage, whenever it is required, thus reducing time."
"We couldn’t be happier with our ROI on this product. It has made managing both storage and VMware simpler and more efficient."
"The deduplication and compression capabilities are powerful, and we see deduplication savings ratios at ten to one and twenty to one."
"Easy to configure and view information of the system's health."
"Implementation of the solution is very simple."
"The most valuable aspect is the use of solid-state storage drives instead of spinning drives."
"Provisioning large numbers of virtual desktops has sped up considerably."
"Using snapshots allows us to automate production database refreshes to development environments in minutes, rather than in hours."
"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."
"The ratio between the physical storage and the storage we use is very high."
"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."
"It is consistently stable; haven't had a single issue with it."
 

Cons

"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."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool."
"Currently, the solution fails to support file screening."
"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."
"What I dislike about Everpure FlashArray is that in the replication, if it is in the pod, we cannot directly add devices to the pod without breaking the relationship."
"It would be nice if Pure had something in its portfolio that provided higher deduplication and compression for backups."
"I would like a feature to integrate with external or cloud solutions."
"I would like to see support for NVMe, end-to-end."
"Perhaps more stability to the InfoSight VMVision feature."
"We face challenges with hardware delivery."
"I want to see the full integration with OneView. I know they have started it, but I haven't had a chance to look at and evaluate it."
"The only thing that I can really compare Nimble to is all-flash because, right now, Nimble is a hybrid solution. I would like to see them come out with an all-flash alternative."
"Honestly, the only thing that could really get better is the price."
"It would have been nice if the vendor had informed us of a known bug that occurred during the firmware upgrade because we could have prevented our only major failure."
"HPE Nimble Storage does not scale well. It needs improvement."
"We are also a user of the SimpliVity stack and I didn't feel that the roadmap for that has played out."
"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."
"The interface look and feel could be improved."
"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."
"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."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"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."
"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 think it should have better performance with small files. With big data, its performance is top notch, but it is difficult to load small files."
 

Pricing and Cost Advice

"The cost has room for improvement."
"We do not incur additional costs beyond the licensing fee."
"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."
"The price is very reasonable when compared to other solutions."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"It's a good price point and it's a solid product for the price."
"Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."
"You can pay extra for Evergreen support, which gives you free upgrades when new features are introduced."
"It is very pricey. You pay for what you get, and this storage solution is great. It is well worth the cost."
"HPE Nimble Storage didn't require a license at the time."
"HPE Nimble Storage is more expensive than some of the other solutions, such as Pure Storage. They charge more for every feature than other vendors."
"If we had stuck with EMC, we would have spent a lot more. We have EMC in-house, we have a bunch of them. Switching to Nimble saved me millions of dollars over the past three years... Nimble fills a need for performance within a budget that is in the sub-million dollar range."
"I believe the array, maintenance, and everything totaled around $140,000 dollars."
"The price is negotiable and when we first received the quote it was expensive, but after dealing with them and receiving a discount, the price is reasonable."
"We buy the arrays outright, so we don't pay anything on an ongoing monthly basis for licensing."
"The price of HPE Nimble Storage is good."
"Kaminario is very competitive on price. They also have a pay per TB model."
"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."
"The licensing is all-inclusive."
"Licensing is very straightforward. The cost was considerably lower than other products we looked at."
"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."
"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."
"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."
