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

"Features like ransomware protection, file lock retention, and third-party integrations (e.g., Superna for ransomware protection) are significant benefits."
"It has allowed us to have more consistent quality controls. It has also allowed us to expand the number of servers in clients processing and accessing data, allowing us to get a lot bigger projects out the door."
"The tool comes with cheap disks and works fast for video content."
"For maximizing storage utilization, PowerScale is great. When you write the data to it, it spreads it out to all the nodes, so you get all the performance from the entire pool."
"My experience when deploying Dell PowerScale (Isilon) was very straightforward, as we had Dell come on site to do all the actual setup, which was a big help."
"It assists with eliminating storage silos because it provides SMB and NFS protocols. PowerScale has also helped free up our employee's time to focus on other business priorities."
"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"
"The product's scalability feature is super easy to use."
"Data redundancy is a key feature, since it can survive failures (disks/servers). We didn’t lose our data or have a service interruption during server/disk failures."
"The most valuable feature is the stability of the product."
"Ceph Storage allows us to add value related to cost and offers a unique experience compared to traditional storage."
"High reliability with commodity hardware."
"I like the distributed and self-healing nature of the product."
"Ceph has simplified my storage integration. I no longer need two or three storage systems, as Ceph can support all my storage needs. I no longer need OpenStack Swift for REST object storage access, I no longer need NFS or GlusterFS for filesystem sharing, and most importantly, I no longer need LVM or DRBD for my virtual machines in OpenStack."
"It's a very performance-intensive, brilliant storage system, and I always recommend it to customers based on its benefits, performance, and scalability."
"radosgw and librados provide a simple integration with clone, snapshots, and other functions that aid in data integrity."
 

Cons

"I have experienced a RAM failure in some of the nodes of Dell PowerScale (Isilon), and that required hardware replacement."
"There is room for improvement in its handling of object storage."
"Dell PowerScale (Isilon) could improve in terms of having some problems with using IPv6 and IPv4 on the same namespace at the same time, which is one of our biggest problems as you have to do some really bad workarounds to get that working."
"The thing that they are working on now, and we are following closely is more native cloud integrations. The way that we envision workloads in the future is around moving compute to data instead of the other way around. So, we would like to have a single pane glass to manage storage across a variety of different platforms, including native cloud. That would be awesome."
"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."
"I'd like to see more Iceland products in the cloud so that we can port our data into different environments if needed. I would also like to see a virtual appliance or software-defined Iceland product."
"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."
"We had some issues with level 1 support. We had to fight with them on repeated issues. There is room for improvement in level 1 support."
"If troubleshooting is needed, the response should be faster."
"Some documentation is very hard to find."
"It needs a better UI for easier installation and management."
"While the documentation for Ceph Storage is helpful, it could be improved."
"Please create a failback solution for OpenStack replication and maybe QoS to allow guaranteed IOPS."
"The management features are pretty good, but they still have room for improvement."
"Routing around slow hardware."
"It would be nice to have a notification feature whenever an important action is completed."
 

Pricing and Cost Advice

"It is an expensive solution."
"The pricing is excellent."
"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 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."
"The pricing for this solution is reasonable."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"I always want things to be less expensive. However, I would say the pricing is fair. Their costs are in alignment with their competitors. It is a good value for the money."
"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."
"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."
"There is no cost for software."
"The other big advantage is that Ceph is free software. Compared to traditional SAN based storage, it is very economical."
"I rate the product’s pricing an eight out of ten."
"The price of Red Hat Ceph Storage is reasonable."
"The price of this product isn't high."
"We never used the paid support."
"The operational overhead is higher compared to Azure because we own the hardware."
