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.

Account Technology Specialist at a tech vendor with 10,001+ employees

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

"It works quite well for us, and I would recommend it."

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."

"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."

"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."

"When compared with Pure Storage FlashBlade, I would recommend Pure Storage FlashBlade; it's easier to set up, easy to expand capacity, and very easy to upgrade."

"It uses the same platform for connectivity so integration is seamless."

"Speed and ease of use are the two most valuable features."

"The initial setup is pretty quick."

More Everpure FlashBlade pros

"The performance, overall, is quite impressive."

"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 we started using, beyond the initial scope for the solution, is the multi-protocol system that allows you to access the same set of files using different network protocols like NFS or SMB. PowerScale’s Unified Permission Model ensures that data security and access permissions are honoured regardless of whether the client is a Windows desktop or a Linux server"

"The most valuable feature of the solution is its performance."

"The tool's most valuable features are scalability and stability."

"The solution has simplified management by consolidating our workloads, and rather than managing all the different workloads on different storage arrays and Windows Servers, we just have one place per data centre where we manage all their unstructured data, saving us time."

"Dell PowerScale (Isilon) stability is solid as a rock."

"My experience with Dell as a vendor is pretty good; they are probably one of the best in the industry."

More Dell PowerScale (Isilon) pros

"IBM has the most number of additional services, this is the main advantage."

"The standout feature of IBM Cloud Object Storage is its top-notch security, making it ideal for sensitive applications like mobile financial transactions."

"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."

"IBM Cloud Object Storage integrates well."

"Overall, I rate IBM Cloud Object Storage a ten out of ten."

More IBM Cloud Object Storage pros

Cons

"It's on the expensive side, as expected for a niche product."

"The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top."

"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."

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

"I would like to see the licensing fees improved as well as the price per terabytes."

"The speed could be improved."

"The integration with S3 needs some improvement."

"I would like to see more monitoring capability included in the next release of this solution."

More Everpure FlashBlade cons

"The initial setup for this solution is complex."

"There is room for improvement in its handling of object storage."

"The pricing is expensive, but I think it's a fair value because it does manage itself."

"PowerScale is not suitable for virtual environments."

"They could improve implementation, as we had to rack and stack it ourselves."

"Perhaps if there was a local chatbot built within the system or on the dashboard where we could directly ask for anything on the OneFS, it could help us."

"We're struggling with the UID mapping and how to configure mapping-related things."

"Because of the magic that it does 'under the hood,' it is very difficult to find out within the system where all your storage is going."

More Dell PowerScale (Isilon) cons

"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."

"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."

"IBM has limited cloud storage."

"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."

"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."

"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."

More IBM Cloud Object Storage cons

Pricing and Cost Advice

"Licensing fees are paid yearly."

"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."

"I feel that the price could always be lowered."

"The pricing for FlashBlade is between cheap and moderate."

"Our customers have seen a reduction in TCO."

"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."

"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."

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

More Everpure FlashBlade pricing and cost advice

"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."

"Dell PowerScale (Isilon) is an expensive solution."

"Dell PowerScale is an expensive solution compared to other products like Qumulo."

"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 pricing for this solution is reasonable."

"The solution is expensive; it is not the cheapest solution out there. If you look at it from a total cost of ownership perspective, then it is a very compelling solution. However, if you're looking at just dollar per terabyte and not looking at the big picture, then you could be distracted by the price. It is not an amazing price, but it's pretty good. It is also very good when you consider the total cost of ownership and ease of management."

"It is a really expensive solution."

"The price of the solution is high."

More Dell PowerScale (Isilon) pricing and cost advice

"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."

"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."
