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

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."
"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."
"I would recommend this solution to other interested companies because it's extremely fast."
"It is very easy to use, and it is very fast."
"I love this solution."
"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."
"The most valuable feature of this solution is performance."
"From the customer's perspective, this is the easiest product that I've tested, it's seamless."
"The fact that we were able to set it up, use it, and, for the most part, didn't have to worry about it after we had it set up has been valuable."
"Our main goal is to do disaster recovery with whatever solution we use and Isilon makes it pretty simple to replicate those workloads over to our secondary data center."
"Its most valuable feature is the DR capabilities replication."
"The most valuable feature of the solution is its performance."
"PowerScale helps our clients consolidate data storage and multiple applications onto a single platform for easier manageability."
"The stability of the solution is good."
"Dell PowerScale is a scalable solution. It allows non-disruptive upgrades and maintenance of the system."
"The tool's most valuable features are scalability and stability."
"IBM Cloud Object Storage integrates well."
"The integration itself is pretty easy. The access appliances create the connection between both environments."
"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."
"IBM has the most number of additional services, this is the main advantage."
"Overall, I rate IBM Cloud Object Storage a ten out of ten."
"The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites."
"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."
 

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."
"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 Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."
"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 like to see more deduplication."
"The features provided for SMB customers are limited."
"Compared to, for example, Hitachi NAS, the solution is not mature at all; it's just in its infancy as far as technology goes."
"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. 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."
"One downside of Dell PowerScale (Isilon) is that it is really complicated to configure."
"It would be nice to see tools like Superna Eyeglass built into PowerScale."
"The improvement should be in AI. Everything is going towards AI."
"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."
"Some improvements to the NFS support would be of interest to us."
"Dell PowerScale (Isilon) could improve the load distribution capability. For example, in some cases, the system load is not distributed automatically on all the nodes but is concentrated only on one."
"Isilon has limitations on the number of files that can be generated."
"The tool's support team and the way the cases are handled by the product's technical support team are both areas of concern where improvements are required."
"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 area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."
"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."
"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."
"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."
"IBM Cloud storage is not cheap, but it could be."
"IBM has limited cloud storage."
 

Pricing and Cost Advice

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."
"The price could be cheaper."
"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."
"We used a reseller for the purchase."
"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."
"The pricing for FlashBlade is between cheap and moderate."
"I rate the tool's pricing a seven to eight out of ten."
"The pricing is excellent."
"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."
"We use the TNA approach which is a great opportunity for us to better manage the licenses based on how much consumption is available for the different customers so we can use that approach and scalability."
"It is a really expensive solution."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"Our company finds the pricing high, but it decreases over time."
"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."
"The solution's licensing cost varies based on capacity and performance requirements."
"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."
"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."
