IT Manager at Regin Dalarna

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.

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.

Cons

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."

"Its configuration should be easier."

"There could be improvements in public cloud integration."

"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade.

"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 see more VM-Aware features in the next release of this solution."

"Commvault has mainly driven the Analytics, providing data and reports. However, the product has room for improvement, especially regarding storage analytics. Upgrading firmware has caused issues, requiring feature disabling to revert to traditional backups. The firmware upgrades sometimes affect Commvault backups."

More Pure Storage FlashBlade cons

"Dell PowerScale (Isilon) is a little bit pricey, and its pricing could be improved."

"The solution's rate structure or rate redundancy needs to be improved."

"We have issues in Brazil with the procurement of solutions because we have to check the entire market and justify the pricing to our audit institutions, making it difficult to keep with the same vendor."

"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."

"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."

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

"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."

"Pricing is an issue. It's quite expensive for the amount of storage we have."

More Dell PowerScale (Isilon) cons

"Its reverse proxy features could be better."

"The developer support could be better."

"There is a lack of good addons to integrate without having to use third-party applications."

"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 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."

"We had minor bugs occasionally."

"With problems, visibility is hard because everything is in containers. Difficult to get to the logs in order to figure out what the problem was."

More MinIO cons
