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

"With Dell PowerScale (Isilon), it uses not just a terabyte but petabytes of data, storing a large amount of data takes within minutes, and you can bring it down to seconds as well, as it does not take much time to upload or copy the data here and there, and upgrades also do not take much time."
"On a scale of one to ten, with one being worst and ten being best, I would rate Dell PowerScale (Isilon) a ten."
"Dell PowerScale is a scalable solution. It allows non-disruptive upgrades and maintenance of the system."
"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 solution's most valuable features are scalability and flexibility."
"The most valuable features of the solution are flexibility and ease of implementation."
"Its scalability has been huge for us."
"Dell PowerScale includes a wealth of features that are important from a security and recovery perspective."
"Replicated and erasure coded pools have allowed for multiple copies to be kept, easy scale-out of additional nodes, and easy replacement of failed hard drives. The solution continues working even when there are errors."
"The most valuable feature is the stability 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."
"I like the distributed and self-healing nature of the product."
"What I found most valuable from Red Hat Ceph Storage is integration because if you are talking about a solution that consists purely of Red Hat products, this is where integration benefits come in. In particular, Red Hat Ceph Storage becomes a single solution for managing the entire environment in terms of the container or the infrastructure, or the worker nodes because it all comes from a single plug."
"The ability to provide block storage and object storage from the same storage cluster is very valuable for us."
"It has helped to save money and scale the storage without limits."
"We are using Ceph internal inexpensive disk and data redundancy without spending extra money on external storage."
 

Cons

"One downside of Dell PowerScale (Isilon) is that it is really complicated to configure."
"There are some missing features in the product, especially when our company needs to do some tape backup, and we see that the tool doesn't have integration capabilities."
"Some improvements to the NFS support would be of interest to us."
"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."
"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."
"Always, there is room for improvement in terms of cybersecurity, as new challenges are continually emerging in the market."
"Dell PowerScale can improve on its multi-tenant part because as a service provider, we have bigger clusters in data centers where we can serve multiple customers and grant them dedicated management points and automation features that can be managed in a multi-tenant environment."
"The cost of Dell PowerScale is currently high and there is room for improvement."
"The licensing cost is excessively high. This is a significant issue from my perspective."
"An area for improvement would be that it's pretty difficult to manage synchronous replication over multiple regions."
"Geo-replication needs improvement. It is a new feature, and not well supported yet."
"Please create a failback solution for OpenStack replication and maybe QoS to allow guaranteed IOPS."
"It would be nice to have a notification feature whenever an important action is completed."
"It took me a long time to get the storage drivers for the communication with Kubernetes up and running. The documentation could improve it is lacking information. I'm not sure if this is a Ceph problem or if Ceph should address this, but it was something I ran into. Additionally, there is a performance issue I am having that I am looking into, but overall I am satisfied with the performance."
"This product uses a lot of CPU and network bandwidth. It needs some deduplication features and to use delta for rebalancing."
"When it comes to the capabilities of Red Hat Ceph Storage such as object, block, and file storage, I am not fully satisfied."
 

Pricing and Cost Advice

"Dell PowerScale is an expensive solution compared to other products like Qumulo."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"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."
"The pricing for this solution is reasonable."
"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."
"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."
"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."
"There is no cost for software."
"Most of time, you can get Ceph with the OpenStack solution in a subscription​​ as a bundle.​"
"The other big advantage is that Ceph is free software. Compared to traditional SAN based storage, it is very economical."
"The operational overhead is higher compared to Azure because we own the hardware."
"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."
"I rate the product’s pricing an eight out of ten."
"The price of this product isn't high."
