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

"Dell has the AI to protect the EMA."

"Dell PowerScale (Isilon) definitely deserves ten out of ten for scalability."

"The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product. This solution has also had a positive impact on our employees' productivity because it reduces the amount of admin that our staff needs to handle."

"The most valuable feature of Dell PowerScale (Isilon) is all the capabilities together."

"The most valuable feature we started using, beyond the initial scope for the solution, is the multi-protocol system that allows you to access the same set of files using different network protocols like NFS or SMB. PowerScale’s Unified Permission Model ensures that data security and access permissions are honoured regardless of whether the client is a Windows desktop or a Linux server"

"PowerScale helped free up our employees' time to focus on other business priorities. There are now automated jobs such as backing up and replicating data, that reduce the footprint we have. Those types of tasks were previously done manually."

"Dell PowerScale helps in saving costs related to power and rack space, reducing physical hardware from over one hundred to twenty-nine chassis."

"The most valuable features of the solution are flexibility and ease of implementation."

More Dell PowerScale (Isilon) pros

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

"The container installation features are good. The S3 feature provisions the storage buckets making it easy. It allows me to spin up the public buckets with open-source technology."

"The ability to spawn a MinIO Tenant on demand and shut it down right after is most valuable."

"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 product does save time for our company."

"Nice web interface, easy to use, with a low memory footprint."

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

"The initial setup was very easy - one click, and it was installed."

More MinIO pros

Cons

"The solution isn't suitable for small environments or small customers."

"There is room for improvement with the updates. It can take a significant amount of time to do a major OS update. However, even though it takes multiple reboots, the cluster stays up. If we want to apply a newer version of the OS, we have to roll back some of the patches so that we can upgrade. It requires a few reboots just to do that. The cluster doesn't come down, everything is still running, but it's time-consuming, at times."

"The management and monitoring tools comprise a disparate suite of products and the roadmap is very unclear. We've got four different products that look after the Isilon, management-wise, and it's a bit of a mess."

"Dell PowerScale (Isilon) certainly has room for improvement; since it does not provide SAN at the moment, I would look for Dell to create a complete unified solution just like NetApp."

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

"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."

"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. You have a peak request on only one node and the others don't do anything."

"I have escalated questions to the technical support team of Dell, and I find the support center to be very poor compared to what it was during EMC's time."

More Dell PowerScale (Isilon) cons

"The only downside I see is that you do not have a complete picture of an object."

"The scalability is one of the limitations we have found. We are looking for another solution but they must provide the same characteristics, such as an affordable price and continuity."

"The solution lacks documentation."

"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 Distributed User Interface (DUI) needs some work. It's hard to view a large set of data on the DUI. It's an issue with the DUI's performance."

"We had minor bugs occasionally."

"The solution should have high availability. Also, support should be quick."

"The product's initial setup phase is complex."

More MinIO cons

Pricing and Cost Advice

"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 price of the solution is high."

"We paid an additional fee to have Dell's ProDeploy Plus team implement it."

"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."

"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."

"It is a really expensive solution."

"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."

"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."

More Dell PowerScale (Isilon) pricing and cost advice

"MinIO is a free open-source solution."

"My company hasn't tried the version of the solution where we need to pay to use it."

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

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

"This is an open-source solution but I am using the licensed version."
