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.

Flexibility and reliability have supported seamless data growth
I cannot think of anything to improve about Dell PowerScale (Isilon). The hardest challenge we have is due to how we've bought things over time. The way that we moved to the PowerEdge platform for the newer systems creates a scale problem as I still buy the older style systems, which are more dense storage. They're different chassis, so the problem we run into in the data center is the depth of the actual equipment. The newer equipment, if we buy an FX910 or a 900, it's a lot shorter in scale than if I buy an 83,000, which is much bigger. This makes it more complicated for deployment.

Enables seamless data replication and supports comprehensive data analytics workflows
The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites. Also, important is the capability to provide RESTful APIs for custom connectors. In terms of security, I advise customers to rotate access keys to enhance protection. Additionally, scalability is effortless as you can add nodes or expand the license.

Quotes from Members

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

Pros

"The first year, we started out with one or five terabytes and it took what was 20 terabytes of storage down to less than one terabyte."
"We chose Pure Storage primarily because of its combination of performance and ease of use."
"The performance is great."
"We have tons of capacity on it."
"I am very satisfied with this solution and I would recommend it to others."
"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."
"We noticed a dramatic increase in application performance when moving it from NetApp to Pure Storage."
"The most valuable features of Pure Storage FlashArray are simplicity, ease of use, and dashboard management."
"Customer service is absolutely satisfying, rating at least nine out of ten, as they have managed previous issues well."
"The single pane of glass for both IT and for the end-user is a valuable feature. On the IT side, I can actually control where things are stored, whether something is stored on solid-state drives or spinning drives... The single pane of glass makes it very easy to use and very easy to understand. We started at 100 terabytes and we moved to 250 and it still feels like the exact same system and we're able to move data as needed."
"The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product."
"Dell PowerScale has the SmartConnect and SmartConnect Pro features. That's why I like the product."
"The solution's most valuable features are scalability and flexibility."
"Since it can scale so easily, as long as I have money to buy more nodes, I can grow it as big as I need to. That is important in our business. As sequencing technologies continue to evolve, and as those technologies evolve, the amount of data generation never gets smaller. It just always seems to get bigger. This is one of the absolute key aspects: We can grow on demand without having to forklift stuff."
"Features like ransomware protection, file lock retention, and third-party integrations (e.g., Superna for ransomware protection) are significant benefits."
"The flexibility and the user-friendly interface are the most valuable features."
"IBM has the most number of additional services, this is the main advantage."
"The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites."
"One of Cloud Object Storage's best features is infinite capacity. This is one of the main advantages if you don't want to use your own storage. You also have the ability to write only, write once, and read many. It's like tape storage but software-based. This feature is essential for financial institutions that require that kind of protection if you write backup or data there."
"IBM has the most number of additional services, this is the main advantage."
"IBM Cloud Object Storage integrates well."
"The most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."
"Overall, I rate IBM Cloud Object Storage a ten out of ten."
"The integration itself is pretty easy. The access appliances create the connection between both environments."
 

Cons

"For large storage needs, it is expensive."
"The way Pure Storage does the controller storage warranty or replacement has been an issue for some people who just replace the controllers every couple of years, and that's where some of the confusion with pricing and support has come in. They should be clear on the way the controller replacements happen, as it is important to know whether or not you can get a good return on them, because it can be a little confusing."
"I’d love to view the average, minimum and maximum performance in the reports (Analysis tab - Performance) but it is only graphics and you need to export data in CSV to find this information."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."
"We understand that they're thinking about it, but one of the things that would be nice is if they added some basic file-level capabilities to the platform."
"The time-to-market could be better at times, but I think that's true for all vendors of hardware."
"We had some issues with level 1 support. We had to fight with them on repeated issues. There is room for improvement in level 1 support."
"If I could improve one thing on Dell PowerScale (Isilon), it would be better object storage as it recently breached into S3, and that capability could be broadened."
"The product needs to improve CLI since commands are complex. The search option is also difficult since you must give the full path."
"The product’s expansion capacity, pricing clarity, and ease of use need improvement."
"The legacy file system for Epsilon didn't scale into the cloud and didn't have a separate OS."
"The deployment of Dell PowerScale (Isilon) is not really complex but depends on the hardware deployment."
"We see room for improvement in Dell PowerScale (Isilon) because we need personnel to effectively utilize all our infrastructure; it's not easy to find skilled people to work on AI and data analysis."
"The solution lacks a cloud version."
"Sometimes technical support lacks a comprehensive understanding of the entire solution, only focusing on the product they support."
"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
"One area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."
"One improvement could be incorporating a feature similar to Dropbox's version history. This would allow users to track modifications made to files over time, which is particularly important for maintaining a record of changes. While the free version might not include this feature, it could be included in the paid version to provide added value to clients. Additionally, having a version history feature that allows users to access modifications made to files over the past three months could be beneficial."
"Room for improvement depends on customer needs. Some customers prefer pure Object Storage using the S3 protocol, while others use a gateway in front of the storage grid to enable CIFS or NFS."
"IBM Cloud storage is not cheap, but it could be."
"The performance could be better. You can never achieve the same performance as hardware, and cloud performance is one of the main issues clients have."
"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
 

Pricing and Cost Advice

"It is light years beyond anything else with the same price point."
"We purchased a license to use this solution and we pay for the storage ourselves."
"The pricing of Pure Storage FlashArray is reasonable."
"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."
"It's a good price point and it's a solid product for the price."
"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."
"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."
"Pure has been flexible with us on the pricing models."
"The price of the solution is high."
"The pricing is excellent."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"This solution is priced slightly higher than others on the market but does offer good quality. With this solution's data reduction and compression, we were able to purchase less. Costs have dropped because of the data rate of compression and deduplication."
"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."
"Price was also a significant factor in our decision to go with PowerScale. The team at EMC, now Dell EMC, came through with a highly competitive offer that tipped the scales towards their solution. There was only one other solution around the same price point, but it could not match PowerScale on features. That other solution is no longer on the market."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"Dell PowerScale is expensive on the start-up side but we can recoup those costs quickly by not having to reapply the savings to other equipment."
"IBM Cloud is cheaper than AWS. If you want to scale your cloud infrastructure, it can be bought at almost the same price."
"You have the option of a monthly or yearly license. Most customers choose the monthly option. I understand what you would like to say. IBM also lets you choose among four types of Cloud Object Storage. The difference is usage, performance, etc. Of course, high-performance storage is more expensive, while low-performance storage is for cold data, and it's really cheap."
"Like most cloud providers, IBM likely charges based on storage capacity, typically per gigabyte or terabyte. Their pricing is competitive when compared to AWS or Microsoft."
"Pricing is not cheap."
