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.

Performance and interface improve data processing speeds but require complex configuration
The most valuable features of VMAX are its performance and GUI interface. We have seen significant improvements in technology over the last four to five years. The snap feature, along with deduplication, has notably enhanced our data processing speeds. We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution.

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."
"Technical support is excellent. I've had very good responses from technical support. We had a couple of cases where we needed support. Some of the communications were purely over email and some has been an actual call to the service desk."
"The management features are well organized and they have a very good dashboard."
"The availability and ease of use are the big features."
"The most valuable features would be its performance, retrieval, recovery, and backup, and it meets the customer's expectations."
"Our clients see a reduction in total cost of ownership by around 40%."
"One feature that's particularly valuable for our finance customers is Pure Storage's safe mode. It protects against ransomware attacks by taking snapshots. Our customers were very impressed with this capability. The data reduction is also impressive compared to other providers."
"Pure Storage is extremely reliable — it's never failed."
"The snapshot feature has been precious for our testing processes, application development, and managing testing environments due to its efficiency and ease of use."
"The ransomware protection feature is housed in a separate unit, specifically addressing the top twenty most critical threats."
"It works very well."
"The most valuable features of VMAX are its performance and GUI interface."
"We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution."
"The product's initial setup phase was good."
"We would buy the solution again without any hesitation."
"The most valuable features of Huawei OceanStor are the dashboards, bandwidth, and data performance."
"The solution is scalable."
"The technical support from Huawei OceanStor is good."
"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 solution works well for non-critical applications that do not require a heavy workload. The tool's all features are valuable."
"Being a Huawei product, initial setup was easy and not difficult at all."
"It is a highly available product."
 

Cons

"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"Pure Storage FlashArray could improve in the area of cryptographic information in the consoles. The user-friendliness could improve. The Pure Storage FlashArray team should come and log into the system with their maintenance credentials and then pull out the information as evidence of cryptography."
"They can also include file services such as NAS shares and CIFS shares. There should be provisioning of the file shares from a unified array."
"The GUI could improve, it could be more intuitive. There is hidden functionality."
"We haven't seen ROI."
"The price of this solution could be improved."
"Many high-end platforms from other vendors like Dell EMC or Hitachi, their backend has Active/Active architecture, unlike Pure Storage FlashArray which doesn't utilize an Active/Active architecture on the backend."
"Pure Storage FlashArray has not helped to decrease the total cost of ownership, and I believe our total cost has probably gone up, but that's balanced by our increased amount of data and number of use cases."
"The scalability of VMAX is somewhat limited, especially in terms of cache scalability. We've had to procure additional engines to address this limitation."
"There is room for improvement in the centralized administration."
"We encountered some challenges during large data migrations that could be addressed for smoother transitions."
"The configuration part of the product is an area with certain shortcomings where improvements are required."
"Improvements are needed in both partition recovery and scalability."
"Huawei is not that cheap."
"I would like to see the next generation all-flash, which could be combined."
"The solution could improve by having better integration."
"The security could be a bit more robust."
"Huawei OceanStor should work on its saturation level and should be able to take up more load. It should give the same performance that it gives at 20 or 30 percent load for 80 percent as well."
"Its data replication features work slowly for nodes."
"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."
"The main concern is regarding the usability of the data storage."
 

Pricing and Cost Advice

"Pure is not a cheap product. It is not something that is inexpensive. But, the total cost of ownership tends to be lower than with other solutions, because you don't need a lot of expertise, you don't need a lot of training or very expensive engineers or very expensive consultants."
"There is an annual or perpetual license required for this solution."
"I would rate it a seven out of ten for pricing. It could be improved."
"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."
"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."
"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."
"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 have had a couple of customers who have complained about the cost. It can be a little more expensive than some of the other platforms. After it has been installed, I have never had a customer say, "I wish we wouldn't have spent all that extra money." They have always been happy with the product after it has been installed. They might be on the fence about it because of the price, but everybody who I have ever seen install it, they are always happy with it."
"It is not a cheap product."
"The price falls within the mid-range, neither inexpensive nor high-priced."
"The price of Huawei OceanStor should be less expensive. It is expensive at the moment."
"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."
"Its price is affordable."
"Huawei OceanStor is a cost-effective storage solution."
"I am satisfied with the tool's pricing, which is in the middle. It is overpriced. I rate it an eight out of ten."
"This product value matches its price."
"The product is cheap."
"Huawei OceanStor is priced very well but is a bit complicated."
