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.

Offers reliable performance and availability for large deployments
I would like to see improvements in Red Hat Ceph Storage not because I necessarily think it needs improvement, but because I generally prefer to do things manually rather than following the containerization part. Current deployments are based on containers, but I deploy manually with my scripts and controls. If there are no Kubernetes-like requirements, I often prefer to deploy a whole manual process. I don't ask for improvements in the deployment model because Red Hat has its own philosophy about making things, but it's my personal choice that I prefer things manually. Some features are available only in the containerization part, so if those are also available in manual deployment, that will help.

Quotes from Members

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

Pros

"Dell PowerScale has the SmartConnect and SmartConnect Pro features. That's why I like the product."
"The most valuable feature for me is SyncIQ."
"What I appreciate about Dell PowerScale (Isilon) are its best features: it supports both file and object storage, and it is very easy to manage."
"The tool's most valuable features are high density and scalability."
"PowerScale allows us to manage storage without managing RAID groups or migrating volumes between controllers. It has really simplified things. We're not having to worry about the underlying infrastructure. That takes care of itself. We just worry about the data. It's really easy for deploying and managing storage at the petabyte scale."
"The solution is stable."
"Features like ransomware protection, file lock retention, and third-party integrations (e.g., Superna for ransomware protection) are significant benefits."
"This is the best platform that we could have for storage utilization. It is affordable and scalable. At the end of the day, it's something that we find very easy to use."
"I really like that Red Hat Ceph Storage can be used as a total solution without any storage area network components."
"Without any extra costs, I was able to provide a redundant environment."
"We are using Ceph internal inexpensive disk and data redundancy without spending extra money on external storage."
"Most of the features are beneficial and one does not stand out above the rest."
"Red Hat Ceph Storage is a reliable solution, it works well."
"Ceph Storage allows us to add value related to cost and offers a unique experience compared to traditional storage."
"Ceph’s ability to adapt to varying types of commodity hardware affords us substantial flexibility and future-proofing."
"The ability to provide block storage and object storage from the same storage cluster is very valuable for us."
 

Cons

"Dell PowerScale's deployment is not easy."
"I would like to see Dell PowerScale (Isilon) improved by enhancing the user interface, OneFS, to make advanced conversation and troubleshooting more specific, upgrade and batch management, providing deeper built-in analytics for performance and capacity planning."
"Dell's customer service needs improvement."
"The solution’s interface and pricing 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 price of the solution could be reduced."
"If I could improve one thing on Dell PowerScale (Isilon), it would be better object storage as it recently breached into S3, and that capability could be broadened."
"I would want to see more AI features with Dell PowerScale (Isilon)."
"Ceph is not a mature product at this time. Guides are misleading and incomplete. You will meet all kind of bugs and errors trying to install the system for the first time. It requires very experienced personnel to support and keep the system in working condition, and install all necessary packets."
"What could be improved in Red Hat Ceph Storage is its user interface or GUI."
"I've heard the integration with OpenShift is great, however, the licensing cost is excessively high."
"In the deployment step, we need to create some config files to add Ceph functions in OpenStack modules (Nova, Cinder, Glance). It would be useful to have a tool that validates the format of the data in those files, before generating a deploy with failures."
"The management features are pretty good, but they still have room for improvement."
"I have encountered issues with stability when replication factor was not 3, which is the default and recommended value. Go below 3 and problems will arise."
"While the documentation for Ceph Storage is helpful, it could be improved."
"While the documentation for Ceph Storage is helpful, it could be improved."
 

Pricing and Cost Advice

"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."
"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."
"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 price of the solution is high."
"The pricing for this solution is reasonable."
"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."
"If you can afford a product like Red Hat Ceph Storage then go for it. If you cannot, then you need to test Ceph and get your hands dirty."
"The other big advantage is that Ceph is free software. Compared to traditional SAN based storage, it is very economical."
"The price of Red Hat Ceph Storage is reasonable."
"Most of time, you can get Ceph with the OpenStack solution in a subscription​​ as a bundle.​"
"I rate the product’s pricing an eight out of ten."
"We never used the paid support."
"The operational overhead is higher compared to Azure because we own the hardware."
"The price of this product isn't high."
