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.

Extends data management capabilities while offering robust options for further enhancement
Dell ECS provides features such as active-active and geo-replication, which offers a good approach for disaster recovery. As a Dell platinum partner, we appreciate that most Dell portfolio products are integrated together. For example, Dell ECS can be integrated with other file share systems or PowerScale without requiring third-party tools. The integration between Dell products is particularly noteworthy because Dell provides the full cycle of storage solutions, from NAS, SAN, hybrid, to object storage. All these solutions are fully integrated together. The pricing is competitive when compared to other vendors. While comparing with HP's offerings, Dell ECS as object storage is one of the best. Pure Storage might offer better pricing, but you won't find the same level of integration across products if you source the full cycle from one vendor. The complete integration of Dell solutions is one of the main features I appreciate, and I often advise my customers to consider this ecosystem. This integration helps with having a single point of contact and support.

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

"I find two features of Pure Storage most valuable. The first is the "safe mode" function, and the second is its simplicity."
"It has been quite satisfactory in performance and scalability."
"Despite the overuse of buzzwords and re-classifications, the storage industry has actually seen dramatic improvements over the last 3-4 years."
"This was our first all-flash storage enclosure, so we saw huge boost in performance for all of our servers."
"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."
"Pure Storage FlashArray is a good product with minimal management requirements once set up correctly and helped reduce our storage footprint from EMC."
"Pure Storage FlashArray has helped decrease the total cost of ownership because we know what the cost is going to be every year; we don't get any hidden fees or upgrade fees, everything is included in the price."
"If you need a high-performance storage appliance that is easy to install and maintain, you pretty much can't go wrong."
"It is a stable platform."
"Dell ECS provides compatibility between on-premises and cloud-based storage, supporting protocols such as S3, which is commonly used in cloud storage, enabling integration between on-premises storage and cloud storage."
"The stability is the most valuable aspect of the solution."
"Dell ECS is a cost-effective solution that provides ease of use and availability."
"The support from Dell ECS is better than NetApp."
"Dell EMC ECS is the leading storage area network, you can do anything with it."
"The performance is good."
"It is a stable solution."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
 

Cons

"I would like to have support available in Spanish."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"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."
"If there is one thing that I did not appreciate about Pure, it is that between the two different lines, which would be FlashBlade and Everpure FlashArray, there is no easy way to migrate LUNs as far as being able to replicate across those platforms."
"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."
"Pricing could be better in comparison to other solutions."
"Based on my experience with various technologies like EMC, NetApp, and Pure Storage, one area for improvement is compliance certifications. NetApp excels in this area, particularly in the American Army or defense sector, where NetApp has approval, whereas others are striving to achieve the same. NetApp also delivers security, ransomware protection, and scale-up capabilities more effectively."
"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."
"If Dell ECS would be available as standalone software, so you can use any hardware with it, would make the solution better. It would also be good if Dell ECS had more integrations with other products."
"Dell ECS could improve the price of the solution. It is expensive."
"One area for product improvement would be the garbage collection process. It takes longer than expected, so speeding up that process would be beneficial."
"The troubleshooting feature of this solution needs to be improved, to allow organizations to fix issues without having to contact the support team."
"The deployment is not easy, and some expertise is required to configure the virtual data center and replication groups."
"However, hardware failures can impact the cluster, making it read-only."
"We have about 20 computing servers on the front end. The computing servers store the data from the network to our Dell EMC storage. We have found recently that the storage has become slower and slower."
"Dell ECS is not fully compatible with S3, as it supports around ninety percent of S3 APIs, which can be improved. Additionally, sometimes there is an issue with memory where it hangs, and they can improve garbage collection, which takes up a lot of space during cleanup."
"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

"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"It's priced higher than the market."
"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."
"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."
"I don't know the exact cost but it's around $1,000."
"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
"When you are paying more than you were paying for the storage space, you'd like the cost to be less. If they could get into the spinning disk kind of cost, that would be it."
"It is light years beyond anything else with the same price point."
"The solution could be cheaper."
"Dell ECS is a cost-effective solution."
"We initially purchased all of the licenses at the same time."
"We are not paying for the license at this stage."
"The solution's cost is quite reasonable."
"The price of Dell ECS should be reduced."
"The charges for this solution are made in blocks of models, which are purchased depending on what features an organization requires."
"The price of Dell ECS should be reduced."
"We acquired VAST Data as a one-time, capital purchase."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
