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.

MinIO should provide an easier subscription model for companies that don't have a huge amount of data. Our company has a maximum of 100 terabytes of data. The solution should provide more bugging tools in the open-source version to encourage people to buy the support services. It's not an easy decision. If I go to the management and tell them that I need to buy a service, there should be an easier subscription model for companies that don't have huge amounts of data. For me, getting a subscription for 15,000 a year for a system already in production might be a bit hard. I think MinIO supports a minimum of one petabyte or 100 terabytes of data. Since we don't have such huge amounts of data, buying a subscription for the solution is a bit difficult. Hence, we're only using the open-source version for now. If MinIO becomes really crucial for our business, we could ask the management to get a subscription.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Dell PowerScale (Isilon) is brilliant for scalability and really, really good in that regard."
"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."
"Dell PowerScale includes a wealth of features that are important from a security and recovery perspective."
"I rate Dell PowerScale (Isilon) a ten out of ten, and we continue to keep buying it."
"The solution is stable."
"The most valuable feature is its single space of storage."
"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."
"I would rate Dell PowerScale (Isilon) as a product a ten out of ten."
"The initial setup was very easy - one click, and it was installed."
"It performs efficiently compared to other solutions."
"The initial setup was straightforward as MinIO provided good support documentation and took a couple of days to complete."
"The most valuable features are that MinIO is open, it works on-premise, and is compatible with the Amazon industry which is great for finding compatible libraries in many languages which is very good for developers."
"The tool’s integration is very easy. This feature has helped us reduce development time. The solution also has many out-of-the-box features like versioning support and management of roles and permissions. The product also supports clustered deployment."
"The stability of MinIO is good."
"MinIO is easy to install and use, especially for standalone installations."
"Good interface and a good approach to development and testing environments."
 

Cons

"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."
"Always, there is room for improvement in terms of cybersecurity, as new challenges are continually emerging in the market."
"The pricing could be reduced."
"It would be nice to see tools like Superna Eyeglass built into PowerScale."
"The analytics could be improved."
"The price of the solution could be reduced."
"Improvements could be made on the object storage side."
"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. That's a little bit of a ding that we have on it. It does so much magic in order to protect itself from drive failures or multiple drive failures, that it automatically handles the provisioning and storage of your data. But by doing that, finding out why a file of a certain size, or a directory of a certain size, is using more storage than is being reported in InsightIQ, is very difficult to discern."
"The product's initial setup phase is complex."
"The main issue we face with MinIO is performance."
"The only downside I see is that you do not have a complete picture of an object."
"The documentation of the solution should improve."
"The solution should have high availability. Also, support should be quick."
"Documentation could be improved."
"Its reverse proxy features could be better."
"The MinIO dashboard is minimal as there are only a couple of features inside the dashboard for a basic user. I would like this to be more robust with more click-around features."
 

Pricing and Cost Advice

"Dell PowerScale (Isilon) is an expensive solution."
"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 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."
"Pricing for this solution is reasonable."
"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."
"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 for this solution is reasonable."
"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."
"This solution is open source so it is free."
"My company hasn't tried the version of the solution where we need to pay to use it."
"We use the solution's open-source version."
"This is an open-source solution but I am using the licensed version."
"We use the solution's open-source version."
"MinIO is a free open-source solution."
