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

"The solution has simplified management by consolidating our workloads. Rather than managing all the different workloads on different storage arrays, Windows Servers, etc., we just have one place per data centre where we manage all their unstructured data, saving us time."
"What I like the most about Dell PowerScale (Isilon) is that the storage capacity is very high."
"Dell PowerScale (Isilon) definitely deserves ten out of ten for scalability."
"The most valuable feature of Dell PowerScale is its scalability."
"It's easy to manage. The web UI is very intuitive, and there's CLI also that you can use to manage it."
"Its most valuable feature is the DR capabilities replication."
"The solution is extremely easy to manage. This is its most valuable feature."
"The single pane of glass for both IT and for the end-user is a valuable feature. On the IT side, I can actually control where things are stored, whether something is stored on solid-state drives or spinning drives... The single pane of glass makes it very easy to use and very easy to understand. We started at 100 terabytes and we moved to 250 and it still feels like the exact same system and we're able to move data as needed."
"The configuration of the solution and the user interface are both quite good."
"We use the solution for cloud storage."
"The scalability feature is used by all users and is critical for our operations."
"We have some legacy servers that can be associated with this structure. With Ceph, we can rearrange these machines and reuse our investment."
"Most valuable features include replication and compression."
"Stratus allows more reliability than all the other types of computers available."
"radosgw and librados provide a simple integration with clone, snapshots, and other functions that aid in data integrity."
"The community support is very good."
 

Cons

"Improvements could be made to reduce the costs and the high level of knowledge needed to maintain and use them. We had old hard drives with moving parts in Dell PowerScale, and due to this, we must switch to a more efficient environment with all-flash."
"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."
"Dell's customer service needs improvement. Specifically, hardware failures under warranty should be addressed within the promised timeline."
"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."
"The biggest weakness is small file handling. Small file compression options are not enabled out of the box. It would be good to have this enabled by default."
"Some improvements to the NFS support would be of interest to us."
"The deployment of Dell PowerScale (Isilon) is not really complex but depends on the hardware deployment."
"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."
"If you use for any other solution like other Kubernetes solutions, it's not very suitable."
"Please create a failback solution for OpenStack replication and maybe QoS to allow guaranteed IOPS."
"When it comes to the capabilities of Red Hat Ceph Storage such as object, block, and file storage, I am not fully satisfied."
"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."
"The licensing cost is excessively high. This is a significant issue from my perspective."
"Rebalancing and recovery are a bit slow."
"I've heard the integration with OpenShift is great, however, the licensing cost is excessively high."
"I have not identified any drawbacks, however, the response to public platform inquiries could be faster."
 

Pricing and Cost Advice

"Pricing for this solution is reasonable."
"Dell PowerScale (Isilon) is an expensive solution."
"Dell PowerScale is an expensive solution compared to other products like Qumulo."
"The price of the solution is high."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"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."
"The only drawback for us is that it's a large upfront investment. This was a huge decision for a startup company to make. It took a bit for us to get over the line on it, but we have not regretted it."
"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."
"We never used the paid support."
"The operational overhead is higher compared to Azure because we own the hardware."
"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."
"Most of time, you can get Ceph with the OpenStack solution in a subscription​​ as a bundle.​"
"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 price of Red Hat Ceph Storage is reasonable."
"The price of this product isn't high."
