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.

Good customer service and support and suitable for large environments
It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

Inexpensive with fast performance enhances data storage efficiency
We are using Huawei OceanStor Dorado for Hyper Metro and under Datacore products and some Sunpro products Huawei OceanStor Dorado is fast and has significantly improved data storage efficiency. The fast performance and reasonable pricing of Huawei OceanStor Dorado are the main reasons we sell…

Quotes from Members

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

Pros

"You can even review the devices from your phone. You don't need to be connected to your company's website or VPN to access alerts and reports. While you can't manage the devices using your phone, you can review all the important details about the machine."
"This was our first all-flash storage enclosure, so we saw huge boost in performance for all of our servers."
"It makes things ten times easier."
"In Pure Storage FlashArray, the dedupe and compression are excellent, and performance is good too."
"The compression and deduplication features help to make the best use of the capacity."
"FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."
"I recommend this solution for production because it has good performance and capacity management."
"The all-flash disc is the most valuable feature of this solution."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks Cheaper than pure solid state without needing to actively manage where the data is located."
"High performance and ease-of-management are the most valuable features."
"We use IntelliFlash products for larger environments, like Qatar Airways."
"Once we got this solution in there, we were able to get the reporting down from eight hours to under 20 minutes."
"Data Compression: Up to 80% space reduction in the database"
"We have been able to realize storage space savings for our virtualization environment and it has reduced our electricity usage by reducing the number of disks needed for the virtual environment."
"It performed great originally, and when it performed great, it was awesome."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"Huawei includes features for file servers and file services. It offers ransomware protection for files stored on servers. However, it does not support blocking websites."
"The platform's most valuable features are reliability, intelligence, and fast performance speed."
"The most valuable feature for me is that it deduces better, whereby it can be assigned six times the usable capacity, depending on the nature of the data."
"Two things really stand out for me. First, there's group cloning, which is very nice. It simplifies managing multiple clones across the group. Second, Huawei's multi-controller architecture with load balancing is a good part."
"Huawei OceanStor Dorado is equipped with powerful controllers"
"Overall, it works fine. It's really easy to use."
"There are very few features that are not available in this program: it has compression, it has duplication, it has a clone, it has the alternator, it has replication, it has the CAP, it has everything and very low latency, all integrated into one system."
"The majority of our customers find this solution simple to use."
 

Cons

"The only issue is the pricing. Because we have competition, our customers always take another brand and say they can save their investment."
"The price of this solution could be improved."
"When it comes to Everpure FlashArray ports shown in the GUI, it would be better if, when one of the Pure array ports went down, there was a possibility to highlight that particular port which has gone down."
"Some of the issues are that it's probably not on a par with other large storage enterprise type products."
"One thing I'd like to see in a future release is integration between their main storage array and what they call their FlashBlade product; to be able to snapshot directly from the primary array into multiple different backup copies on FlashBlade."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"I would like FlashArray to add reports that help us forecast our predicted resource needs based on current usage."
"Going forward, don't complicate things for the customers."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"I would say it's somewhat scalable, maybe not so much as some of the competition, but we don't really care."
"It's annoying that if you turn on SMB3 (as opposed to the earlier CIFS protocol), then it is not possible to access a file store using a mixture of SMB and NFS."
"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."
"The solution as it is right now is not very stable. The stability seems to have eroded."
"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."
"Snapshots are not as easy to access as on a NetApp device."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"Having distinct modules for data compression and encryption features enhances flexibility and performance optimization for users with varying requirements."
"If they implement a backup solution directly into the OceanStor then it will be a valuable feature."
"Huawei OceanStor Dorado could improve by having a multi-tier cloud option and additional protocols."
"Huawei OceanStor Dorado's biggest weakness is its lack of cloud integration."
"The technology and the features need improvement."
"They should add a feature to the platform to help us manage storage communication with one of the vendors."
"In additional features, it would be easier to do snapshots on a regular basis. So, like, a new feature that would allow you to take snapshots every hour."
"The price must be improved."
 

Pricing and Cost Advice

"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"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."
"We have seen a reduction in TCO."
"For us, as the customer, it reduced the price of the management."
"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."
"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."
"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."
"In terms of other contemporary arrays, Pure is something you need to have a use case for, as it's not priced for you to buy one off-the-shelf. If you have a use case, heavy lift Oracle Databases, any type of noticeable virtual desktop infrastructure (VDI), or need low latency and high throughput, you should consider all-flash at least and probably Pure Storage."
"I think we pay around 100 grand per year for three arrays or four arrays."
"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."
"It is an expensive solution."
"This product is not too expensive, and the price is competitive on the market."
"Huawei OceanStor Dorado has a competitive price compared to other solutions."
"There are lots of features included with this solution and some of them require additional licensing, such as creating high availability storage using a cluster."
"The pricing is very competitive."
"Huawei has very good pricing. They have some promotions that can be taken advantage of at certain times of the year, such as the end of December. They are providing aggressive pricing. In the Pakistan market, they are ready to beat any vendor in Pakistan because they want to grab the market."
"The pricing is one thing that works for them. I think their pricing is more competitively affordable than these top competitors."
"I rate the pricing a six on a scale from one to ten, where one is expensive, not cost-effective, and ten is cheap."
