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.
Alan Powers - PeerSpot reviewer
HPC CTO at a manufacturing company with 10,001+ employees
Stability-wise, a device that has been up and running for years
The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"Using this solution has improved our consolidation ratio and it saves us a lot of space."
"Pure Storage FlashArray has significantly improved our data center performance. It handles high workloads efficiently, providing better performance in the environment. With increased storage capacity, it has led to improved overall system performance. The tool's technology is a standout feature. It has helped me reduce storage costs by 15 percent."
"Despite the overuse of buzzwords and re-classifications, the storage industry has actually seen dramatic improvements over the last 3-4 years."
"This solution is very scalable."
"My advice to others looking into using Everpure FlashArray is that it's a really good product, especially if your main purpose is to get high speed with more redundancy and reliability; then go for it."
"It's simple, powerful, and ready to use."
"The white glove customer service that I get is their greatest value."
"Firstly, dedupe is the most valuable feature, hands down, and simplifying storage is also a big win overall."
"It is a highly available product."
"The solution has improved our organization by speeding up our operations and increasing the scale of operations (growth capacity)."
"The solution is easy to use."
"We struggle with finding anything to improve, as it's a powerful solution and is missing nothing."

"The write performance could be improved because it is less than half of the read performance."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
 

Pricing and Cost Advice

"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."
"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."
"Our costs are around $100,000."
"Price is about the only thing that's wrong with it. A little bit better pricing would be great."
"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."
"The price of the solution can be a bit expensive. There is an additional fee for support."
"Pricing is moderate. It is neither cheap nor expensive."
"It's roughly affordable."
"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."
"The price of the solution could be less expensive. However, there are not any licensing costs."
"The price of the license is quite low, so it's not something special or expensive."
"The product is cheap."
"This product value matches its price."
"Huawei's prices are very good compared to those of its competitors."
"Huawei OceanStor is priced very well but is a bit complicated."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
