- "Isilon has limitations on the number of files that can be generated."
What is our primary use case?
How has it helped my organization?
Isilon is flexible in supporting various data workloads while keeping them protected. Dell continues to release updates and patches which enhance the use of this solution. This includes offering ransomware protection.
We are working with Dell to implement a cyber security solution, which is called the air gap solution. We also have Dell Data Domain systems. We back up the data from Isilon or any other system into Dell Data Domain. From Dell Data Domain, we offload to the air gap and secure the data into the air gap or Isilon.
The system is robust. It has had a big impact on the efficiency of our organization. It serves as storage for our core application, which is a revenue-generating application. It plays a key role in our business.
Isilon has the ability to scale file data, although we have not explored this within our business yet.
What is most valuable?
The offloading of data from Isilon to ECS object storage has been cost-effective.
What needs improvement?
Isilon has limitations on the number of files that can be generated.

Works
Data access and security platform that has drastically increased efficiency ratios
Pros and Cons
- "The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product. This solution has also had a positive impact on our employees' productivity because it reduces the amount of admin that our staff needs to handle."
- "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."
What is our primary use case?
We use this solution for high concurrency connection and data capacity.
How has it helped my organization?
It has improved our organization by filling a gap in some of our home-built applications. It provides a single unified space across the scalable infrastructure. There are no longer multiple points of entry required for the workload.
The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product. This solution has also had a positive impact on our employees' productivity because it reduces the amount of admin that our staff needs to handle.
PowerScale has helped us reduce our overall risk. We lean on the regulatory compliance and SCD drives to ensure data security. It offers various data multi-protocol capabilities. They recently introduced S3, as well as traditional file workloads including SNB, NFS, and SFTP. The security is built-in and includes SED and self-encrypting drives. This allows us to instantly monitor compliance.
What is most valuable?
The scalability of this solution has been most valuable. We have been able to start with a specified workload size and be able to double, triple, or tenfold it without having to change the environment.
What needs improvement?
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.
For how long have I used the solution?
I have been using this solution for ten years.
What do I think about the stability of the solution?
This is a stable solution.
What do I think about the scalability of the solution?
This is a scalable solution. It offers multiple petabytes and tens of thousands of concurrent connections.
Which solution did I use previously and why did I switch?
Other solutions that we have used have been administratively intensive.
What was our ROI?
We have been leveraging this platform and folding it into our application stack. This has removed the need for a third-party solution which has reduced overall costs and provided ROI.
What other advice do I have?
This solution requires maintenance. Once the platform is properly deployed, there is a BAU component of maintenance including the replacement of hard drives.

Senior Consultant at a tech company with 11-50 employees
Good stability and performance with the capability to scale
Pros and Cons
- "The stability of the solution is good."
- "The solution can be a bit complex for those not well versed in the technology."
What is most valuable?
The solution is easy to use.
The product has global name recognition.
The performance, overall, is quite impressive.
The stability of the solution is good.
What needs improvement?
The solution lacks a cloud version.
It would be useful if the solution could direct to AWS or Google Cloud effectively or have an AWS version. With the global lockdown conditions, you can't get to the site. It would be easier if it was connected to the cloud.
The solution can be a bit complex for those not well versed in the technology.
For how long have I used the solution?
I've been using this solution for a few years now.
What do I think about the stability of the solution?
The solution, so far, has been very stable for us. We don't have issues with Isilon itself, however, every once in a while we do face a few stability issues.
What do I think about the scalability of the solution?
The solution is scalable, however, it's quite complex, so it's not exactly straightforward. For organizations that have a lot of items they need to upgrade, it's good to have support to help. However, the solution can scale if a company needs to.
We have a few hundred users on the solution right now.
How are customer service and technical support?
The technical support aspect of the solution has been good. We've been satisfied with their level of attention and find them to be knowledgable and helpful.
Which solution did I use previously and why did I switch?
We didn't previously use a different solution, however, we are looking to switch solutions now, simply due to the fact that we would like to migrate to the cloud.
How was the initial setup?
The initial setup was a bit complex for personal not knowledgeable with the solution. When you are just shown a manual, it does take a while to understand how everything works. It's not exactly straightforward.
What's my experience with pricing, setup cost, and licensing?
While the initial setup isn't too expensive, it can end up being expensive depending on how many machines you have or how big you are.
What other advice do I have?
We're a reseller of Isilon products.
I'm not sure which version of the solution we are using. It's one of the version seven releases.
Right now, we are researching moving from on-premise to cloud, and want to know whether there is something that is more convenient than Isilon when moving to a cloud server.
For example, with EMC, if you have something on-premise, and if you want a cloud version, you should rather take ECS. The company finds the concept a bit confusing, so they are looking around for something that is similar in terms of ease of use, and yet has a cloud version as an option.
As it stands now, I'd advise new users to rather use the Dell EMC service and learn on the job. It will be faster to get set up and be able to handle the solution.
It's still a fairly good solution. Overall, I'd rate it eight out of ten.
Which deployment model are you using for this solution?
On-premises

What was our ROI?
We have seen a return on investment with the hybrid model. However, we haven't seen a return on investment with the all-flash model because it is a bit more expensive than other products. It takes three to five years to see a return on investment with the solution.
What other advice do I have?
I usually recommend this product for enterprise companies that require massive capacity. It is not for small and medium-sized businesses. The solution provides faster backup. I would recommend the solution to other users. We use Dell PowerScale (Isilon) for long-term data retention. Dell is doing an excellent job of raising product awareness among partners and customers through advertisements.
Overall, I rate the solution a seven out of ten.
