I would evaluate the customer service and technical support for Dell PowerScale (Isilon) as great. We've sent out emails at 6:00 in the morning and received replies at 7:15. We've been working with the same team for at least as long as I've been there, which is about two years, and this consistency has been awesome. If I had to rate them from one to ten, with ten being the best, I would definitely give them a ten.
Which solution did I use previously and why did I switch?
Before adopting Dell PowerScale (Isilon), we were using a few old Unispheres, Unities, and PowerStore. Most of those were all end of life, which is why we made the change.
How was the initial setup?

System Engineer at a tech vendor with 10,001+ employees
Storage has supported large-scale virtualization tests but still needs stronger API expertise
Pros and Cons
- "The initial setup was easy because we received support from their partners, which enabled us to install it without difficulty."
- "I believe the support engineers need to improve their skills."
What is our primary use case?
Dell PowerScale's primary use case for our organization is server virtualization.
What is most valuable?
I would describe the overall operational efficiency and ease of use of Dell PowerScale as satisfactory given our current testing phase. We purchased the entry-level model, so the speed is not optimal, but we do not require high speed, which is acceptable for our needs. Regarding efficiency, we have not yet started the service. We will begin our main service one month later, so I am unable to evaluate the other functions at this time. We have not yet conducted measurements on these capabilities.
What needs improvement?
I believe the support engineers need to improve their skills. In our case, the engineer provides adequate hardware support, but they lack expertise in supporting Dell PowerScale's API and Kubernetes-related APIs such as CSI API. Although Dell PowerScale can support Kubernetes API, our engineer does not possess the necessary knowledge in this area.
For how long have I used the solution?
I have been working with Dell PowerScale for only one or two months since we purchased it two or three months ago. We acquired Dell PowerStore one month prior to that. The timeframe has been too short to fully evaluate the solution.
What do I think about the scalability of the solution?
Dell PowerScale has demonstrated scalability, with our company having more than 30,000 people testing it.
How are customer service and support?
I would rate Dell technical support as normal and not problematic. As I work in Korea, the server and related support is excellent, but the storage support is somewhat inconsistent.
On a scale from one to ten, I evaluate Dell technical support as six or seven.
I believe the product itself is adequate, but the Korean support engineer needs to improve their skills.
Which solution did I use previously and why did I switch?
Before Dell PowerScale, we had already used Dell servers, but this is the first time our company has implemented storage from Dell.
How was the initial setup?
The initial setup was easy because we received support from their partners, which enabled us to install it without difficulty.
What about the implementation team?
We require approximately 50 administrators for this implementation.
What was our ROI?
To measure the effectiveness of Dell PowerScale, before we purchased the product, our requirement was efficiency of at least three times. We did not have many additional requirements beyond this efficiency goal and the project schedule and delivery timeline.
What's my experience with pricing, setup cost, and licensing?
Regarding the price of Dell PowerScale, I consider it a budget storage solution.
What other advice do I have?
We purchased Dell PowerScale from their partner. I provide this review with a rating of six out of ten.

- "The product itself is capable of very much, but the initial deployment experience can be lacking possibly because it does not incorporate any design phase."
What is our primary use case?
We were looking at getting a solution in for storage. I have worked with storage before, and I have worked with parallel storage systems more than NAS appliances.
I have worked with Lustre, PowerScale, and NetApp as well. I would describe myself more as a user of NetApp and PowerScale. I work with customers who work with Dell PowerScale (Isilon).
We are a consultancy firm, so we also partner with Dell and we deploy and deliver AI solutions, and Dell PowerScale (Isilon) sits underneath those. This makes it very important to our operations.
What is most valuable?
The top three valuable features for me are the redundancy, reliability, and mixed NFS and Samba share, SMB sharing.
We use a tool called IOR, which measures the IOPS and the throughput for very tailored and specific I/O scenarios. This allows you to test it under different conditions.
Dell PowerScale (Isilon) is brilliant for scalability and really, really good in that regard. They are adding new features all the time, which I have not used yet, but they are adding RDMA technology. This provides really low-latency connections between the clients and the machine itself, which is really good for AI-type workloads as well.

What do I think about the scalability of the solution?
We utilize 70,000 terabytes on Dell PowerScale (Isilon).
How are customer service and support?
Generally, when we put in a ticket on something regarding Dell PowerScale (Isilon), it takes a while to get to the right person as we wade through first-level support.
Once we reach the second level person or the right level, the support is great and awesome.
I would rate the support for Dell PowerScale (Isilon) as probably an eight.
Which solution did I use previously and why did I switch?
We switched from NetApp before I joined my team, and while we were using Dell PowerScale (Isilon), we merged with other organizations that were using different solutions and sunset those uses into Dell PowerScale (Isilon). They were using Pure Storage in some other places.
How was the initial setup?
I would describe my experience deploying Dell PowerScale (Isilon) as easy.
It's a very quick, seamless product, and once we get it in, it's just a matter of setting up some policies to copy data over, whether for an LCR or standing up a completely fresh new one.
With Dell support always there to help, it remains pretty straightforward since the software is intuitive.
Maintenance and upgrades for Dell PowerScale (Isilon) are also pretty straightforward; sometimes they're a little slow due to the size of our cluster, however, overall, the support is good and maintenance is easy.
What was our ROI?
Certainly, we have seen return on investment and peace of mind, especially with our two clusters that are linked together, where one is a disaster recovery solution for the other. We get a lot of peace of mind from that, and it's worth every penny.
The second cluster of Dell PowerScale (Isilon) gives us flexibility for small things like code upgrades, all the way to scenarios where we have lost this data center or data, allowing us to check if data is still intact on the other side; we can flip easily.
What's my experience with pricing, setup cost, and licensing?
I don't get involved in the pricing, TCO costs, and licensing of Dell PowerScale (Isilon) since I'm more involved in engineering what we need, so the prices are hammered out elsewhere.
Which other solutions did I evaluate?
We haven't considered any other solutions besides Dell PowerScale (Isilon).
What other advice do I have?
My role using Dell PowerScale (Isilon) involves overseeing the hardware and the software, and managing some of the permissions and access to the data on the array.
Overall, I would rate Dell PowerScale (Isilon) a nine 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.

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.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.
