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

"It uses the same platform for connectivity so integration is seamless."
"The fact that the solution is extremely stable and it works really great each dollar spent on this solution is worth it."
"We chose Pure because we like their support model and we like their performance."
"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."
"I would rate Pure Storage FlashBlade a ten out of ten."
"I would recommend this solution to other interested companies because it's extremely fast."
"From the customer's perspective, this is the easiest product that I've tested, it's seamless."
"The flexibility and the user-friendly interface are the most valuable features."
"The reliability and stability of Dell PowerScale (Isilon) is good, with no downtime."
"You plug in a new node and data starts migrating over to it, and IT spreads out the load. We've added multiple nodes to the system since deploying it. The process is pretty seamless, and we are able to do it with no downtime. It's a very easy process to do."
"The solution's flexibility for supporting various data workloads while keeping them protected is great."
"Its scalability has been huge for us."
"PowerScale helps our clients consolidate data storage and multiple applications onto a single platform for easier manageability."
"The technical support has been excellent. I would give them a ten out of ten for support."
"The capacity and scalability are what I appreciate the most about it; that was huge for us. We saw its benefits immediately after we started using it."
"The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites."
"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 most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."
"The integration itself is pretty easy. The access appliances create the connection between both environments."
"IBM Cloud Object Storage integrates well."
"One of Cloud Object Storage's best features is infinite capacity."
"Overall, I rate IBM Cloud Object Storage a ten out of ten."
"IBM has the most number of additional services, this is the main advantage."
 

Cons

"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."
"I would like to see better integration."
"The solution is expensive."
"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products."
"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."
"There could be improvements in public cloud integration."
"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."
"The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."
"The price always has room for improvement."
"They could improve implementation, as we had to rack and stack it ourselves."
"Technical support could be improved. Whenever we have a hiccup, we'd like to get it fixed maybe quicker."
"I have experienced a RAM failure in some of the nodes of Dell PowerScale (Isilon), and that required hardware replacement."
"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."
"It would be nice to see tools like Superna Eyeglass built into PowerScale."
"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."
"My experience with customer service and technical support has been challenging. The reason is that it is difficult to find subject matter experts around the solution."
"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 Cloud storage is not cheap, but it could be."
"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."
"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."
"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."
"IBM Cloud storage is not cheap, but it could be."
"IBM has limited cloud storage."
 

Pricing and Cost Advice

"The price is a little high."
"I understand that it is competitively priced compared to other brands."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"Our licensing is renewed annually."
"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."
"The price could be cheaper."
"Pricing for this solution is reasonable."
"It is a really expensive solution."
"The price of Dell PowerScale (Isilon) is reasonable."
"The pricing is excellent."
"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"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 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."
"Our company finds the pricing high, but it decreases over time."
"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."
