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

"Using this solution has made our backups more reliable."
"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."
"The main feature I have found to be product replication."
"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."
"Pure Storage FlashBlade is stable, strong, fast, and modern, and it's an enterprise-class object storage product."
"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."
"The number one aspect of FlashBlade is performance; the ability to move large amounts of data through a training array is pretty much unparalleled, and the scalability has been great."
"Pure Storage FlashBlade's scalability is one of the most valuable features, and importantly, it always works, allowing for seamless upgrades."
"The best thing is that it works. We don't have to maintain it too much; we usually upgrade once a year."
"Features like ransomware protection, file lock retention, and third-party integrations (e.g., Superna for ransomware protection) are significant benefits."
"I don't have to rebuild the cluster to add a node."
"This has really changed the way our company can acquire and process data in the field, allowing us to differentiate ourselves against all our competitors."
"We use the solution internally to support our own managed servers and run our own support center."
"What I appreciate about Dell PowerScale (Isilon) are its best features: it supports both file and object storage, and it is very easy to manage."
"Dell has the AI to protect the EMA."
"My experience with Dell as a vendor is pretty good; they are probably one of the best in the industry."
"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 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."
"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."
"One of Cloud Object Storage's best features is infinite capacity."
"IBM Cloud Object Storage integrates well."
 

Cons

"The speed could be improved."
"The solution is expensive."
"In my opinion, one way Pure Storage FlashBlade can be improved is by having more compatibility between the FlashArray and FlashBlade, allowing for synchronized data between both platforms."
"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person, and nine out of ten times, we get an email right back saying that person is off until tomorrow."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"The feature that we're waiting on is better integration with the cell services."
"The price of this solution could be made more affordable."
"Its configuration should be easier."
"Some improvements to the NFS support would be of interest to us."
"The only thing that I think PowerScale could do better is improving the HTTP data access protocol."
"There aren't many templates still coming out for it. They need to provide templates so we can copy and paste what we've done in the past to future, new things."
"I would want to see more AI features with Dell PowerScale (Isilon)."
"I'd like to see more Iceland products in the cloud so that we can port our data into different environments if needed. I would also like to see a virtual appliance or software-defined Iceland product."
"The price always has room for improvement."
"The management and monitoring tools comprise a disparate suite of products and the roadmap is very unclear. We've got four different products that look after the Isilon, management-wise, and it's a bit of a mess."
"Backward compatibility is something Dell PowerScale (Isilon) could work on."
"One area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."
"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."
"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 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."
"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
"IBM Cloud storage is not cheap, but it could be."
"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 product is very expensive."
"I rate the tool's pricing a seven to eight out of ten."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"The price could be cheaper."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"I understand that it is competitively priced compared to other brands."
"Our licensing is renewed annually."
"We used a reseller for the purchase."
"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."
"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 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 pricing is excellent."
"The solution's licensing cost varies based on capacity and performance requirements."
"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 expensive on the start-up side but we can recoup those costs quickly by not having to reapply the savings to other equipment."
"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."
"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."
