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

"Compared to Unity, these arrays offer significant advantages, such as NVMe technology and higher IOPS."
"The most valuable feature is it never goes down. We can expand and create volumes."
"Everpure FlashArray is very good with AI development and is very suitable for low downtime and critical mission storage, so customers who need critical mission storage and those chasing performance should consider this solution."
"The best feature is consistently lower latency, even when IOPS crank up to over 75K. The product maintains submillisecond response time, which is incredible."
"For us, the most valuable feature is the compression and deduplication. Being able to deploy a three to one ratio for storage is absolutely critical in today's world with the growing need for storage and the growing need for more space."
"What I like most about this solution, is the speed, resiliency and scalability."
"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."
"Manageability is its most valuable feature; it is simplified storage, as we don't have to maintain or administer it on a daily basis, which is good, and we can depend on the solution's ability to phone home and leverage the built-in support function of the product."
"With Dell PowerScale (Isilon), it uses not just a terabyte but petabytes of data, storing a large amount of data takes within minutes, and you can bring it down to seconds as well, as it does not take much time to upload or copy the data here and there, and upgrades also do not take much time."
"Dell PowerScale overall is easy to use."
"I can certainly recommend PowerScale for mission-critical workloads, it is a powerful but simple platform with little administration overhead."
"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."
"Regarding stability, I find no lagging, crashing, or downtime with Dell PowerScale (Isilon), and it is a highly scalable, stable, and reliable solution that I have experienced."
"Customer service is absolutely satisfying, rating at least nine out of ten, as they have managed previous issues well."
"Dell PowerScale (Isilon) definitely deserves ten out of ten for scalability."
"The standout feature of IBM Cloud Object Storage is its top-notch security, making it ideal for sensitive applications like mobile financial transactions."
"IBM has the most number of additional services, this is the main advantage."
"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 Cloud Object Storage integrates well."
"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."
"Overall, I rate IBM Cloud Object Storage a ten out of ten."
 

Cons

"Currently, the solution fails to support file screening."
"I would like to see them lower the costs."
"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."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"In the next release, I would like to see file-level encryption."
"We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client."
"It would be nice to have a better view of the allocated capacity on their Platform as a Service solution because we have to do some manual calculations to understand how much we are going to pay every month to use the storage that is allocated."
"Pure will probably have to move to other layers of the stack, not only storage but, maybe, hyperconverged."
"The solution isn't suitable for small environments or small customers."
"Isilon has limitations on the number of files that can be generated."
"Beyond containerized storage support and software updating, I have had very bad experiences with Dell PowerScale (Isilon) because they present more issues than other storage options, even when compared with NetApp."
"Dell PowerScale can improve on its multi-tenant part because as a service provider, we have bigger clusters in data centers where we can serve multiple customers and grant them dedicated management points and automation features that can be managed in a multi-tenant environment."
"Sometimes, it takes too long to set up everything. That's something I would want them to improve."
"We lost our technical sales reps about two years ago. We haven't gotten one assigned to us and we'd love to have one."
"Improvements could be made on the object storage side."
"The support offered by the product is an area of concern where improvements are required."
"One area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."
"IBM has limited cloud storage."
"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."
"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."
"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 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."
 

Pricing and Cost Advice

"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"We have seen a reduction in TCO."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"I would prefer that they lower their pricing."
"The price was more favorable than Dell EMC."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"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..."
"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."
"It is a really expensive solution."
"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."
"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."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"The only drawback for us is that it's a large upfront investment. This was a huge decision for a startup company to make. It took a bit for us to get over the line on it, but we have not regretted it."
"I always want things to be less expensive. However, I would say the pricing is fair. Their costs are in alignment with their competitors. It is a good value for the money."
"Dell PowerScale (Isilon) is an expensive solution."
"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"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."
"IBM Cloud is cheaper than AWS. If you want to scale your cloud infrastructure, it can be bought at almost the same price."
"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."
