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

"They are doing very well with the product."
"This solution has improved how our organization functions in the way that it has essentially made us not have to think about storage."
"Using this solution has made our backups more reliable."
"It's very easy-to-use."
"The tool's most valuable feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."
"For those who are interested in using this solution, I would recommend it."
"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."
"Pure Storage FlashBlade's scalability is one of the most valuable features, and importantly, it always works, allowing for seamless upgrades."
"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 features of Dell PowerScale (Isilon) that I prefer the most include some of the newer technologies that are on it, which would include SmartSync and the ability for the data mover to continue to make incremental changes."
"It has saved me from having to hire one person over the last six months, and our IT team has gotten about 40 percent of its time back."
"I rate Dell PowerScale (Isilon) a ten out of ten, and we continue to keep buying it."
"The most valuable feature of the solution is its performance."
"The tool comes with cheap disks and works fast for video content."
"Using this product has enabled us to maximize the business value of our data because now, we can store all of our data in one place."
"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."
"The integration itself is pretty easy. The access appliances create the connection between both environments."
"IBM Cloud Object Storage integrates well."
"IBM has the most number of additional services, this is the main advantage."
"IBM Cloud Object Storage integrates well."
"One of Cloud Object Storage's best features is infinite capacity."
"The standout feature of IBM Cloud Object Storage is its top-notch security, making it ideal for sensitive applications like mobile financial transactions."
"Overall, I rate IBM Cloud Object Storage a ten out of ten."
"The most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."
 

Cons

"I would like to have Snapshots and Snapmail in the next release."
"I would like to see more deduplication."
"I would like to see better integration."
"The feature that we're waiting on is better integration with the cell services."
"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."
"I would like to see more VM-Aware features in the next release of this solution."
"I have not seen ROI."
"The documentational aspect of FlashBlade needs improvement."
"The solution’s interface and pricing could be improved."
"The analytics could be improved."
"That said, for the other security features, it would be helpful if Tenable - and I know it's outside the scope of this question itself - had Isilon-specific plugins."
"Dell PowerScale (Isilon) could be improved, particularly the UI, which could use some polishing as far as ease of use for the customer."
"The pricing could be reduced."
"There are some missing features in the product, especially when our company needs to do some tape backup, and we see that the tool doesn't have integration capabilities."
"Data storage performance needs to be improved."
"There is room for improvement with the updates. It can take a significant amount of time to do a major OS update. However, even though it takes multiple reboots, the cluster stays up. If we want to apply a newer version of the OS, we have to roll back some of the patches so that we can upgrade. It requires a few reboots just to do that. The cluster doesn't come down, everything is still running, but it's time-consuming, at times."
"One area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."
"IBM Cloud storage is not cheap, but it could be."
"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
"IBM has limited cloud storage."
"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
"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."
"Sometimes technical support lacks a comprehensive understanding of the entire solution, only focusing on the product they support."
"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

"The product is very expensive."
"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."
"The price of this solution could be made more affordable."
"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"The price is a little high."
"I feel that the price could always be lowered."
"Our licensing is renewed annually."
"The pricing for this solution is reasonable."
"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 a really expensive solution."
"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."
"The general cost for a system like this is expensive. The total cost depends on your use case. You need to pay for every additional feature that you use."
"Dell PowerScale (Isilon) is an expensive solution."
"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."
"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."
"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."
"Pricing is not cheap."
