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 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

"It is pretty much just plug and play. There is not that much to do with it. It is very easy to use."
"We were actually able to do multiple upgrades, including head upgrades and moving between the platforms, M20 and M50, over the years. We have never once lost a ping and have never had an outage due to an OS upgrade or a complete head upgrade."
"The initial setup was very straightforward and very quick. It was up and running in our data center within 24 hours of receiving it."
"The biggest return on investment for us is not having to do a swap out of the arrays every five years."
"Pure Storage FlashArray has helped us to improve the reporting and the billing cycle."
"The product has not gone down in a year, so I would say that it is stable, and we haven't seen any high spikes in read/write latency."
"In Pure Storage FlashArray, the dedupe and compression are excellent, and performance is good too."
"It helps to simplify storage. For most of our customers, when they move to Pure Storage, storage becomes an afterthought."
"The setup and the price are the most valuable and not the features related."
"We deployed Huawei OceanStor because we had some problems increasing the number of users on our database and were suffering from slowness and downtime, and after implementing All-Flash now most of our data-intensive transactions are sitting under All-Flash and we've gotten quite a good response from our users."
"Stability: The product is designed to have always HA (High Availability) with redundant network and processors."
"OceanStor brings to us the best performance as storage for our virtualization cluster, allowing a better performance in the apps that need to manipulate a huge amount of data."
"Pricing is very fair. It's competitively priced."
"The solution is easy to scale as needed."
"Huawei provides excellent and efficient support, and the product is a good price."
"We get a quick response in case any component defaults. We have seen the benefits mostly."
"Inline compression"
"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."
"The K2 has basically removed storage as a bottleneck in our datacenter."
"The GUI is very straightforward and easy to use."
"It is consistently stable; haven't had a single issue with it."
"Using snapshots allows us to automate production database refreshes to development environments in minutes, rather than in hours."
"Latency is definitely the big key for us."
"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."
 

Cons

"We ran into some issues with the program at first and we had to work around those issues to fix our problems."
"Enhanced documentation and beginner-friendly guidelines would benefit users with less configuration experience."
"We have not seen a reduction in our TCO nor have we seen ROI."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"I would recommend improvements in the graphical user interface, specifically a detailed hardware view that would allow us to see the individual drives and individual controllers more easily, as currently, they are presenting only a higher-level view."
"We haven't seen ROI yet."
"In the next release I would like to see integration into other third-party player providers like Google."
"The price of Pure Storage FlashArray could be better."
"Huawei currently lacks a solution for high-performance AI, unlike other companies like DDN, WekaIO, or IBM BlueStore."
"Technical support is okay. However, sometimes within the support system, they provide some sort of canned automatic reply to the customer instead of setting up communication with the customers."
"The duration of the built-in snapshot technology must be improved."
"The GUI is the only thing I would like to see improved, and the user interface is not so user friendly."
"From a political perspective, there are issues selling Chinese brands to Western companies, as some may not be permitted to use them."
"The technical support has been a let down for us. It's something the company has to work on. We haven't been satisfied with their level of service."
"Huawei OceanStor could improve the deployment stage, configuration, and documentation."
"The upgrading process needs improvement. Deploy it and notify the customers when new versions and stuff comes out. I don't think they're doing that well."
"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."
"The management graphical interface needs more improvement."
"The front panel of the drive shelf doesn't always seat firmly."
"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 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."
"I'd give it a perfect rating if I could push it to 300,000 IOPS like they promote; we just haven't been able to push that many IOPS out of our system."
"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."
"I would like to see them work with Cisco, so it comes off the FIs, instead of having to go through my 10-gig network."
 

Pricing and Cost Advice

"There is an annual or perpetual license required for this solution."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"My organization has a yearly license, but I believe that Pure Storage FlashArray has capacity-based licenses as well. I'm definitely happy with the pricing."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"Pure has been flexible with us on the pricing models."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"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."
"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."
"Overall, the solution's pricing was cheaper."
"The tool's pricing is competitive and affordable. It has the best possible pricing that we can get from Huawei. The prices are fixed and there are no additional costs."
"Payment is determined by the amount of storage capacity required, and we have paid 50,000 euros for our usage."
"Huawei OceanStor is a cost-effective storage solution."
"The price of the license is quite low, so it's not something special or expensive."
"I am satisfied with the tool's pricing, which is in the middle. It is overpriced. I rate it an eight out of ten."
"The price of the solution could be less expensive. However, there are not any licensing costs."
"The pricing depends on the features the customer wants, such as storage, RAM, and processors, but in general, Huawei is much cheaper compared to Dell and Cisco."
"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 licensing is all-inclusive."
"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."
"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."
"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."
"Kaminario is very competitive on price. They also have a pay per TB model."
