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

"Pure Storage FlashBlade is stable, strong, fast, and modern, and it's an enterprise-class object storage product."
"It's very easy-to-use."
"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."
"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."
"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."
"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."
"I would recommend this solution to other interested companies because it's extremely fast."
"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."
"Based on the flexibility of the system itself, it was easy for us to manage the growth by buying individual nodes as needed."
"The most valuable feature is its single space of storage."
"My advice to other companies considering Dell PowerScale (Isilon) is that it takes a little time to understand the product, but once you have it set up and running, it will run stable for all its lifetime."
"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."
"The system is robust, has had a big impact on the efficiency of our organization, and serves as storage for our core application, which is a revenue-generating application that plays a key role in our business."
"The flexibility and the user-friendly interface are the most valuable features."
"I would rate Dell PowerScale (Isilon) as a product a ten out of ten."
"The solution has simplified management by consolidating our workloads. Rather than managing all the different workloads on different storage arrays, Windows Servers, etc., we just have one place per data centre where we manage all their unstructured data, saving us time."
"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."
"The integration itself is pretty easy. The access appliances create the connection between both environments."
"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."
"The standout feature of IBM Cloud Object Storage is its top-notch security, making it ideal for sensitive applications like mobile financial transactions."
"The most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."
"IBM Cloud Object Storage integrates well."
"Overall, I rate IBM Cloud Object Storage a ten out of ten."
 

Cons

"I would like to see more VM-Aware features in the next release of this solution."
"The features provided for SMB customers are limited."
"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."
"Its configuration should be easier."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."
"I have not seen ROI."
"The feature that we're waiting on is better integration with the cell services."
"In the past year, it hasn't been as great. They seem to just follow KBS."
"The UID mapping and how to configure mapping-related things is a struggle."
"Always, there is room for improvement in terms of cybersecurity, as new challenges are continually emerging in the market."
"Dell PowerScale's deployment is not easy."
"Improvements could be made to reduce the costs and the high level of knowledge needed to maintain and use them."
"The thing that they are working on now, and we are following closely is more native cloud integrations. The way that we envision workloads in the future is around moving compute to data instead of the other way around. So, we would like to have a single pane glass to manage storage across a variety of different platforms, including native cloud. That would be awesome."
"The technical support is average. There are certainly not the best that we have ever dealt with, but far from the worst ones."
"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."
"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."
"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
"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."
"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."
"One area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."
"IBM has limited cloud storage."
"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."
 

Pricing and Cost Advice

"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."
"Our licensing is renewed annually."
"We used a reseller for the purchase."
"The price of this solution could be made more affordable."
"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."
"I rate the tool's pricing a seven to eight out of ten."
"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."
"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."
"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."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"Dell PowerScale (Isilon) is an expensive solution."
"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."
"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."
"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"Dell PowerScale is an expensive solution compared to other products like Qumulo."
"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."
"Pricing is not 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."
