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.

Uses a proprietary technology with simple interface and has easy deployment
If you are not generating a substantial amount of data, the available storage space might suffice, making scalability less of a concern. However, if your data generation increases and you require more storage, Huawei OceanStor offers solutions to expand your storage capacity. Expanding storage resources can involve additional costs and configuration efforts. Acquiring more storage solutions and ensuring their integration with your existing setup might require a significant investment of time and resources. While this process can be complex, it allows for seamless scalability as your data storage needs grow. I rate the solution’s scalability an eight out of ten.

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 most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."
"It benefits our IT organization in the way that it's easier for the administrators to manage."
"My favorite feature about Pure Storage FlashArray is definitely the simplicity; in one word, it's simple to install, simple to upgrade, simple to maintain, and simple to manage."
"The scalability is good."
"There is no comparison performance-wise."
"Has also helped simplify storage for us. The other person we put in there, took about a week to implement. And we had both arrays set up within around four hours with a thirty minute drive time between the two locations."
"NVMe data storage platform that's easy to set up and easy to use. It's stable, with a lower response time, and quick technical support."
"We actually originally went with a competitor's product, and after about eight months, a lot of wrangling, had them buy it back from us, and then we bought a similar Pure Storage product, and it's just been great."
"We struggle with finding anything to improve, as it's a powerful solution and is missing nothing."
"Its technical support team is helpful."
"The solution is easy to install and configure and it's also very stable."
"The pricing is very reasonable."
"The management of the solution is easy and documentation is very much simple, so if someone is new to the solution all they need to do is follow the documentation and they can handle the product with ease."
"The performance and ease of management are the most valuable features."
"The most valuable feature of Huawei OceanStor is the hybrid applications."
"Being a Huawei product, initial setup was easy and not difficult at all."
"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."
"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."
"The most valuable feature is definitely the always-on data deduplication."
"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."
"Technical support is absolutely great."
"Rocketing IOPS results in performance we don't have to fixate on, so we can instead focus efforts on other layers in the stack, knowing that our SAN layer is lightning fast, with capacity to spare."
"Go with it. I tell people all the time they need to take a serious look at it."
"The ratio between the physical storage and the storage we use is very high."
 

Cons

"Its price needs improvement. Its price is almost double than any other flash storage solution."
"The initial setup of the product is complex."
"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."
"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"I would like to see support for NVMe, end-to-end."
"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."
"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."
"I would love to see a true one click upgrade solution."
"Customer support is very good but if you want support and you don't have SNS switches as well, the complete solution is not there."
"We did experience a little latency with this solution."
"The main concern is regarding the usability of the data storage."
"The solution needs to improve the compression side of the application."
"The overall price of the solution should be reduced."
"Its storage capacity could be better."
"The energy could be better."
"Configuration complexity and the tools available."
"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."
"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 interface look and feel could be improved."
"Improved scale and budget planning with flexibility of the solution for budget needs and efficiency for growth with the great optimization ratio due to the nature of our use."
"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."
"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."
"The front panel of the drive shelf doesn't always seat firmly."
 

Pricing and Cost Advice

"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."
"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."
"You get what you pay for. It is expensive, but it really works."
"There is an annual or perpetual license required for this solution."
"Pure Storage FlashArray's pricing is very competitive."
"Pure is typically more expensive than everyone else. You get what you pay for, but I have lost deals to similar solutions because of pricing. They include everything, and that's another positive about Pure Storage. They aren't trying to nickel and dime their customers for different features. It is all included in one price. The license is by capacity, and the price depends on the capacity and the discount we're getting from the vendor. You get the SKU of the physical appliance, support, and maintenance, and that's it. You're licensed for whatever feature they offer. It is all rolled up into the price of the appliance."
"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."
"Pricing is very competitive, and it's better than other competitors."
"We pay a monthly licensing fee for this solution. The price could be less expensive."
"Huawei OceanStor is a cost-effective storage solution."
"Payment is determined by the amount of storage capacity required, and we have paid 50,000 euros for our usage."
"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."
"It's roughly affordable."
"Huawei's prices are very good compared to those of its competitors."
"Overall, the solution's pricing was cheaper."
"I am satisfied with the tool's pricing, which is in the middle. It is overpriced. I rate it an eight out of ten."
"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."
"Licensing is very straightforward. The cost was considerably lower than other products we looked at."
"The licensing is all-inclusive."
"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."
"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."
