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

"I love this solution."
"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."
"If you are looking for a new storage array, Pure Storage is, what I call 'the new kids on the block' who don't need to pull legacy systems with it."
"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."
"It uses the same platform for connectivity so integration is seamless."
"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."
"The solution is very easy to manage."
"We have seen a reduction in the total cost of ownership by around 20%."
"Prior to Isilon, we had to access data from multiple different platforms, and this solution offers unified storage and the ability to consolidate and migrate data, which was a big step forward and allowed us to cut costs by eliminating multiple platforms and putting it all on one array."
"Dell PowerScale's performance is good."
"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."
"I would rate Dell PowerScale (Isilon) as a product a ten out of ten."
"Its scalability has been huge for us."
"The performance, overall, is quite impressive."
"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."
"The most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."
"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."
"Overall, I rate IBM Cloud Object Storage a ten out of ten."
"One of Cloud Object Storage's best features is infinite capacity."
"The integration itself is pretty easy. The access appliances create the connection between both environments."
"IBM Cloud Object Storage integrates well."
"IBM Cloud Object Storage integrates well."
 

Cons

"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."
"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."
"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."
"I would like to see more VM-Aware features in the next release of this solution."
"I would like to see more VM-Aware features in the next release of this solution."
"It would be nice if you could store file-based in the same box with the same technology."
"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."
"Pure Storage FlashBlade should improve on more cloud integration."
"The initial setup for this solution is complex."
"Dell's customer service needs improvement. Specifically, hardware failures under warranty should be addressed within the promised timeline."
"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."
"We had some issues with level 1 support. We had to fight with them on repeated issues. There is room for improvement in level 1 support."
"The solution can be a bit complex for those not well versed in the technology."
"Data storage performance needs to be improved."
"The solution's rate structure or rate redundancy needs to be improved."
"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."
"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."
"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."
"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."
"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."
"One area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."
"IBM has limited cloud storage."
 

Pricing and Cost Advice

"I feel that the price could always be lowered."
"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."
"Our licensing is renewed annually."
"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 pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."
"I understand that it is competitively priced compared to other brands."
"Licensing fees are paid yearly."
"The pricing for FlashBlade is between cheap and moderate."
"The price of Dell PowerScale (Isilon) is reasonable."
"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 is an expensive solution compared to other products like Qumulo."
"Dell PowerScale (Isilon) is an expensive solution."
"Our company finds the pricing high, but it decreases over time."
"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."
"The solution's licensing cost varies based on capacity and performance requirements."
"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."
"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."
"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."
