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

"Running SAP on Pure Storage helps a lot without doing any further tuning to improve application performance."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"Technical support is good."
"The reliability is very good."
"The best features of Pure Storage FlashArray are its ease of use and user-friendly interface, and the performance allows all types of services to be visualized from a single point of interface, making it more robust and user-friendly."
"Pure Storage FlashArray is simple and easy to use. It offers protection when removing devices. It has the ability to undo deletes."
"The speed is the most valuable feature of this solution."
"My favorite feature about Pure Storage FlashArray is definitely the simplicity; in one word, it's simple to install, simple to upgrade, simple to maintain, and simple to manage."
"The solution in general has allowed us to move off of multiple Windows boxes where they had huge data stores, and we migrated it to the Isilon, making it easier and more cost-effective with just one point of contact."
"Dell PowerScale's performance is good."
"This is the best platform that we could have for storage utilization. It is affordable and scalable. At the end of the day, it's something that we find very easy to use."
"It is stable and very user-friendly."
"Dell PowerScale (Isilon) actually combined a shared file system that scales seamlessly and works effectively, making the blocking and tackling exactly what was advertised."
"The most valuable feature for me is SyncIQ."
"What I like the most about Dell PowerScale (Isilon) is that the storage capacity is very high."
"Prior to Isilon, we had to access data from multiple different platforms, and this solution offers unified storage and the ability to consolidate and migrate data, which was a big step forward and allowed us to cut costs by eliminating multiple platforms and putting it all on one array."
"The most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."
"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."
"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."
"One of Cloud Object Storage's best features is infinite capacity."
"IBM Cloud Object Storage integrates well."
"IBM Cloud Object Storage integrates well."
"The standout feature of IBM Cloud Object Storage is its top-notch security, making it ideal for sensitive applications like mobile financial transactions."
 

Cons

"I would like to see support for NVMe, end-to-end."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"We would like to see more cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array."
"The support for NFS protocols right out-of-the-box need improvement. I'm used to other storage vendors who have NFS support right out-of-the-box, and Pure Storage doesn't seem to have anything."
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."
"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."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"The latest release contains bugs that shouldn't be in a production environment. Two incidents impacted our client, including hardware-related bugs. They need to be more cautious in testing before they release."
"Improvements could be made to reduce the costs and the high level of knowledge needed to maintain and use them."
"The downside of Dell PowerScale (Isilon) is that if we are replacing a drive, sometimes in the worst-case scenarios, some of the other drives will also go to the SmartFail state."
"We have had issues with internal load balancing between some of the shelves. That is an ongoing issue that support is trying to address."
"My experience with customer service and technical support has been challenging. The reason is that it is difficult to find subject matter experts around the solution."
"Technical support could be improved. Whenever we have a hiccup, we'd like to get it fixed maybe quicker."
"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."
"The cost of Dell PowerScale is currently high and there is room for improvement."
"Since our Dell PowerScale (Isilon) is our own on-prem in-house built system, we don't have many up-to-date resources, and we're still a few years behind."
"Sometimes technical support lacks a comprehensive understanding of the entire solution, only focusing on the product they support."
"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."
"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
"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 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."
"IBM Cloud storage is not cheap, but it could be."
 

Pricing and Cost Advice

"Cost-wise, it's been very effective."
"We feel that the pricing is fair and the licensing process was easy for both."
"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."
"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."
"Because of the SSD, it is cheaper because I am not purchasing so many disks."
"Pure Storage has not helped us to reduce our licensing costs."
"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"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."
"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."
"It is a really expensive solution."
"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."
"It is an expensive solution."
"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."
"We use the TNA approach which is a great opportunity for us to better manage the licenses based on how much consumption is available for the different customers so we can use that approach and scalability."
"The solution's licensing cost varies based on capacity and performance requirements."
"The price of the solution is high."
"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."
"IBM Cloud is cheaper than AWS. If you want to scale your cloud infrastructure, it can be bought at almost the same price."
"Pricing is not cheap."
