Has handled backup storage needs reliably and supports seamless upgrades
In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

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 tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."
"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."
"It's very easy-to-use."
"There has been a reduction in the total cost of ownership by around 20%."
"We haven't had any issues with it, it's easy to use, and the speed is incredible."
"We chose Pure because we like their support model and we like their performance."
"If you are looking for a new storage array, Pure Storage is, what I call 'the new kids on the block' who don't need to pull legacy systems with it."
"The ease of deployment and management has helped us simplify our storage."
"The most valuable features of the solution are flexibility and ease of implementation."
"PowerScale helped free up our employees' time to focus on other business priorities. There are now automated jobs such as backing up and replicating data, that reduce the footprint we have. Those types of tasks were previously done manually."
"Dell PowerScale (Isilon) helps improve the way the organization functions through massive scalability, high performance, a single file system, high availability and reliability, flexible protocols, support for NFS, SMB, HDFS, strong security, cloud integration, efficiency, data protection, snapshot, queue, and sync queue, optimized for unstructured data."
"The solution allows me to use SSMDS to store data for end users and share it within different locations."
"Customer service has been really good."
"Certainly, we have seen return on investment and peace of mind, especially with our two clusters that are linked together, where one is a disaster recovery solution for the other."
"Features like ransomware protection, file lock retention, and third-party integrations (e.g., Superna for ransomware protection) are significant benefits."
"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."
"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 standout feature of IBM Cloud Object Storage is its top-notch security, making it ideal for sensitive applications like mobile financial transactions."
"The integration itself is pretty easy. The access appliances create the connection between both environments."
"IBM Cloud Object Storage integrates well."
 

Cons

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."
"They need better integration with public clouds along with a better hybrid solution."
"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."
"The speed could be improved."
"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."
"We have one system at a customer's site that has had a lot of problems over the last year — I think maintenance was required over seven times before everything was corrected."
"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."
"The feature that we're waiting on is better integration with the cell services."
"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."
"Dell PowerScale (Isilon) certainly has room for improvement; since it does not provide SAN at the moment, I would look for Dell to create a complete unified solution just like NetApp."
"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."
"We're still fairly new with it. It's been a pretty positive experience thus far. However, they could improve implementation, as we had to rack and stack it ourselves."
"We're struggling with the UID mapping and how to configure mapping-related things."
"I would make Dell PowerScale (Isilon) better by improving SmartSync in the graphical user interface. Currently, everything has to be done through the command line, and I prefer having a graphical interface."
"Sometimes, it takes too long to set up everything. That's something I would want them to improve."
"The pricing could be reduced."
"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
"The performance could be better. It isn't bad, but everything is network-based, so you have a performance penalty on the network. You can never achieve the same performance as hardware. That's the disadvantage of cloud storage solutions in general. Cloud performance is one of the main issues clients have."
"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."
"If I had to choose one area, it would be making the consoles more intuitive would be helpful. Sometimes, they can be a little complicated if you're not familiar with them."
"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."
 

Pricing and Cost Advice

"The price of this solution could be made more affordable."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"I feel that the price could always be lowered."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."
"Our customers have seen a reduction in TCO."
"The product is very expensive."
"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."
"It's a high-cost offering amounting to three or four million Swedish kronor, or about $400,000 or euros, for approximately 480 terabytes of storage."
"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."
"Our company finds the pricing high, but it decreases over time."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"The pricing is expensive, but I think it's a fair value because it does manage itself. It definitely is much simpler than any of the other scale-out storage platforms that we've looked at in the past."
"The platform is not cheap. However, on the software side, you can choose what you want license. So, you can start your licensing with the features that you need, then after buying the platform add some other features."
"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."
"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."
"Pricing is not cheap."
"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."
