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.

Provides good object storage functionalities

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

"The inter-cluster replication feature, called SyncIQ, allows you to set up all of the jobs and move your data entirely, either timely or all at once."

"There are also the policies that you set up on replication and purging files, and policies for something called WORM. That's a "write once, read many," where you can't overwrite certain files or certain data. It puts them in a "protected mode" where it becomes very difficult for someone to accidentally delete. We use that for certain files or certain directories, because we're dealing with video and some video has to be protected for chain-of-custody purposes. The WORM feature works great."

"I buy Dell PowerScale (Isilon) because of the price, service, and technology, and the technology that is particularly good for my company is that I have two Dell PowerScale (Isilon) systems in two sites, and I use replication between them with Superna software, which is a third-party Dell technology."

"The solution allows me to use SSMDS to store data for end users and share it within different locations."

"The solution is stable."

"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 most valuable features are scalability and flexibility."

"The technical support has been excellent. I would give them a ten out of ten for support."

More Dell PowerScale (Isilon) pros

"The most valuable feature is the ease of management and administration."

"The solution has good compatibility with different kinds of storage."

"The product does save time for our company."

"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."

"Saves a lot of time in generating and managing documents."

"The initial setup was straightforward as MinIO provided good support documentation and took a couple of days to complete."

"Very good at object retrieval."

"I use the solution's basic object storage functionalities, like AWS S3 compatible APIs and creating buckets."

More MinIO pros

Cons

"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."

"Data storage performance needs to be improved."

"Always, there is room for improvement in terms of cybersecurity, as new challenges are continually emerging in the market."

"The analytics could be improved."

"The downside of Dell PowerScale (Isilon) is that if we are replacing a drive, sometimes in the worst-case scenarios, some of the other drives will also go to the SmartFail state."

"The deployment of Dell PowerScale (Isilon) is not really complex but depends on the hardware deployment."

"I have experienced a RAM failure in some of the nodes of Dell PowerScale (Isilon), and that required hardware replacement."

"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."

More Dell PowerScale (Isilon) cons

"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."

"MinIO could use a time patch on it. It could also use better documentation for some languages like Python."

"We had minor bugs occasionally."

"The documentation of the solution should improve."

"There should be the ability to expand the size after it has already been deployed. Currently, you cannot do that. It doesn't support an increase in size. Each time we spawn a new MinIO, we need to track the particular MinIO instance or tenant that has the file. Therefore, we had to create a multi-tenant solution that tracks the MinIO that has our artifacts. It isn't in one single instance. It should have better multi-tenancy support."

"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 product's initial setup phase is complex."

More MinIO cons

Pricing and Cost Advice

"Dell PowerScale (Isilon) is an expensive solution."

"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 product with a high storage capacity suitable for large data requirements."

"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."

"This solution is priced slightly higher than others on the market but does offer good quality. With this solution's data reduction and compression, we were able to purchase less. Costs have dropped because of the data rate of compression and deduplication."

"The pricing is excellent."

"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."

"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."

More Dell PowerScale (Isilon) pricing and cost advice

"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."

"MinIO is a free open-source solution."

"This solution is open source so it is free."

"We use the solution's open-source version."
