Unified video storage has simplified data management and improved lifecycle planning
Pros and Cons
- "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."
- "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."
What is our primary use case?
My use cases for Dell PowerScale (Isilon) include CCTV, video management, video server, and archival storage.
What is most valuable?
What I like about Dell PowerScale (Isilon) are its best features, as it supports file and object storage, and it is very easy to manage.
The main benefit that Dell PowerScale (Isilon) brings to the table is that it gives the organization good file management.
What needs improvement?
I think Dell PowerScale (Isilon) is very good right now. Perhaps improvements could be made on the CPU level with a better CPU. I haven't used the NVIDIA yet, but a better Intel CPU would be beneficial.
The functionality that I would like to see enhanced in the future for Dell PowerScale (Isilon) is SmartPool for lifecycle management of data. I need more features, particularly for data migration and the ability to segregate data from old to new systems for lifecycle management.
For how long have I used the solution?
I have been working with Dell PowerScale (Isilon) for about 13 years.
What do I think about the stability of the solution?
I assess the stability and reliability of Dell PowerScale (Isilon) as having no crashes, but there have been performance issues. After someone performed a performance analysis and migration, I resolved the issues with SmartConnect, and the SmartConnect feature is effective as it resolves our performance issues.
How are customer service and support?
I have escalated questions to the technical support and customer service team of Dell. The support center is very poor from Dell. Compared to when it was EMC before, Dell support is getting worse nowadays, with less support.
The response time is concerning. Even if you buy ProSupport Plus, they state within two hours, but after two hours, nobody contacts you. The response time shows there is no sense of urgency. Compared to EMC, the support in our region is not as good as it was before.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
Before adopting Dell PowerScale (Isilon), the company was using NetApp.
I decided to switch from NetApp to Dell PowerScale (Isilon) because of feature advantages like file system and data protection. It is easy to manage compared to NetApp, and I think the features are better than NetApp from a feature perspective.
How was the initial setup?
I have knowledge about the deployment process of Dell PowerScale (Isilon).
My experience with deploying Dell PowerScale (Isilon) is that the challenges are more related to working with the network team on their side. The OneFS itself is very straightforward and easy.
What other advice do I have?
Dell PowerScale (Isilon) serves as a storage node and compute node in this case.
Cost saving is one benefit. The organization finds it easy to manage resources, and it is easy to get to market. We can analyze the data, which makes it much easier to go to market.
I would advise other organizations considering Dell PowerScale (Isilon) that it is easy to manage, and it consolidates all traditional NAS instead of separating file systems and protection levels. NAS is easy, especially the OneFS operating system.
Dell PowerScale (Isilon) may play major roles for small and medium-sized organizations.
My organization falls under small and medium-sized organizations in terms of size and revenue.
Dell PowerScale (Isilon) has features that specifically cater to the needs of small and medium organizations, as you can start with three nodes and then increase to 252 nodes, allowing you to start small and grow along the way.
I rate Dell PowerScale (Isilon) as a product and solution a nine out of ten.

Snapshot feature enhances data protection and malware monitoring
Pros and Cons
- "Eyeglass is used to monitor for malware, which is very useful for us."
- "Customer service is absolutely satisfying, rating at least nine out of ten, as they have managed previous issues well."
- "Improvements could be made to reduce the costs and the high level of knowledge needed to maintain and use them."
- "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."
What is our primary use case?
We primarily use Dell PowerScale for archive purposes. It functions as a large NAS.
What is most valuable?
One of the features we use in both PowerScale and Pure Storage is the snapshot feature. It's really important for us.
Additionally, Eyeglass is used to monitor for malware, which is very useful for us.
What needs improvement?
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.
For how long have I used the solution?
I have been working with PowerScale for six years.
What do I think about the scalability of the solution?
It's probably very good. However, due to both cost and the knowledge required to maintain and use them, there are considerations about scalability.
How are customer service and support?
Customer service is absolutely satisfying, rating at least nine out of ten, as they have managed previous issues well.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We do work with Dell and PowerScale, however, we are going to remove them, and as for now, it's going to be in 2026 since Pure Storage has a more cost-efficient model of storage use.
How was the initial setup?
The initial setup requires extensive knowledge. I have to take very expensive courses just to set it up. It's not easy, taking maybe one or two weeks of learning before I should start to use it, which makes it costly.
What was our ROI?
I do believe that it delivered ROI, however, we see a better return of investment with other products we have considered.
What's my experience with pricing, setup cost, and licensing?
Every time we purchase a PowerScale solution, we buy four nodes for one data center and four for another, with five years of maintenance covered by Dell. It's a high-cost offering amounting to three or four million Swedish kronor, or about $400,000 or euros, for approximately 480 terabytes of storage.
Which other solutions did I evaluate?
We evaluated other options. Other solutions did not match our requirements, so we chose FlashArrayX instead of a new PowerMax since it was half the price.
What other advice do I have?
If you know how to handle it, Dell PowerScale is a good product. However, Pure Storage offers similar or even better performance at a lower cost, so I rather recommend Pure Storage if you are looking for efficiency and cost benefits.
Overall, I rate PowerScale an eight out of ten.

Scalable and reliable data management enables seamless growth across extensive storage
Pros and Cons
- "My advice to other companies considering Dell PowerScale (Isilon) is that it takes a little time to understand the product, but once you have it set up and running, it will run stable for all its lifetime."
- "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."
What is our primary use case?
Our primary use case for Dell PowerScale (Isilon) is that it's the central storage platform for the whole university.
What is most valuable?
One of the most valuable features I find in Dell PowerScale (Isilon) is the scalability, as you can extend, extend, extend over time without having to move the file system.
Also, the separation between different access zones is a tenant system that really allows me to completely separate data streams, ensuring that one group of tenants is not allowed to touch or see any of the other tenants' data.
What needs improvement?
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.
For how long have I used the solution?
I have been using Dell PowerScale (Isilon) for around about 17 years.
What do I think about the stability of the solution?
A specific example of where Dell PowerScale (Isilon) made a noticeable improvement or impact on my business operations is that we had a performance impact for around about one week in the whole 17 years, which wasn't really downtime.
What do I think about the scalability of the solution?
The benefit I have realized from using Dell PowerScale (Isilon) is first of all the scalability; we started on PowerScale with around about 300 terabytes and are now two and a half petabytes, still on the same file system.
How are customer service and support?
I would evaluate Dell's support as mostly outstanding because, at least for me, I always find a way to find someone who has enough experience to help me with my problem. For easy problems, I have been through several times, but for complicated problems, I will find someone who can truly help me.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
Prior to adopting Dell PowerScale (Isilon), I was using another solution called Isilon, and I had the first Isilon outside of the labs ever delivered to the customer.
How was the initial setup?
My experience with deploying Dell PowerScale (Isilon) spans 17 years, and I think I have faced every type of problem. In every situation, I have found someone who could help me come out of the situation before anybody would recognize that there was a problem.
What about the implementation team?
Dell PowerScale (Isilon) has features that specifically cater to my needs, such as the separation between different access zones. It's a tenant system that really allows me to completely separate data streams to have legal aspects realized, ensuring that one group of tenants are not allowed to touch or see any of the other tenants' data.
What was our ROI?
I have realized a return on my investment with Dell PowerScale (Isilon). It's worth the money because of the total cost where you only pay one person to run the whole environment instead of paying 15 people to run the same on cheap hardware.
What's my experience with pricing, setup cost, and licensing?
My experience with pricing, setup costs, and licensing for Dell PowerScale (Isilon) shows it's a premium platform, so it's a big amount of money. Not too many universities in Germany are willing to spend, but I'm a one-man shop, so I'm driving and running the whole platform, which is much cheaper compared to a cheap platform where you need many people to operate it.
Which other solutions did I evaluate?
Before choosing Dell PowerScale (Isilon), I considered different vendors like NetApp and others as competitors. They had their advantages, but the overall package was better suited for our requests with Dell PowerScale (Isilon), so that was the reason for our choice.
What other advice do I have?
My advice to other companies considering Dell PowerScale (Isilon) is that it takes a little time to understand the product, but once you have it set up and running, it will run stable for all its lifetime. I rate Dell PowerScale (Isilon) a nine out of ten.
