Managing efficiently with user-friendly interfaces for monitoring and managing resources
We normally recommend Dell ECS to enterprise customers and government customers Dell ECS is very easy to handle, primarily because the web UI dashboard and everything is very easy to manage for every customer. They can monitor the DPS, access failures, bandwidth, failed requests, and latency.…
Eric Burgueño - PeerSpot reviewer
Simplified data management, tremendously reducing our users’ cognitive overhead
The only thing that I think PowerScale could do better is improving the HTTP data access protocol. At the present, you cannot protect access to data via HTTP or HTTPS the same way that you can secure data access through other protocols like NFS or SMB. You can either access a file because it can be access by anyone in the organization, or you cannot at all. There is no in-between. HTTP is not considered a first-class data access protocol, so the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply. However, with the recent introduction of S3 starting from OneFS 9, I believe the necessary plumbing is already there for HTTPS to also be elevated to a first-class protocol in the future because both protocols sit behind a web server under the hood. It does not sound like it would be too complicated to implement, but it would be a valuable feature and it is currently missing.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is a stable solution."
"The tool is easy to use."
"The scalability is good."
"The most valuable feature for me is off-site storage."
"Dell's technical support team is good."
"It is 100% stable. It is also scalable."
"It's definitely good for unstructured data. In earlier days, we had Centera, so for the DR it's really good. It has load balancing facility, and we're using it with the Kemp Load Balancer."
"The performance is good."
"Features like ransomware protection, file lock retention, and third-party integrations (e.g., Superna for ransomware protection) are significant benefits."
"PowerScale helped free up our employees' time to focus on other business priorities. There are now automated jobs such as backing up and replicating data, that reduce the footprint we have. Those types of tasks were previously done manually."
"The stability of the solution is good."
"Customer service is absolutely satisfying, rating at least nine out of ten, as they have managed previous issues well."
"The solution allows me to use SSMDS to store data for end users and share it within different locations."
"This has been a valuable solution for our business overall. It offers business continuity and replication features."
"PowerScale has made it extremely easy to scale file data across our organization. We have two implementations of Isilon. One is a replica of the other. When scaling, we add nodes to each location and expand the cluster. The process is straightforward."
"Dell PowerScale is a scalable solution. It allows non-disruptive upgrades and maintenance of the system."
 

Cons

"Dell EMC ECS could improve by having Relational Database Services(RDS) to review progress. Additionally, if the training was provided it would be a benefit, it would be good for our engineers."
"One area for product improvement would be the garbage collection process. It takes longer than expected, so speeding up that process would be beneficial."
"The setup is very complex."
"You should be able to calculate so that when it's full it's 100% full, not just 90%."
"Dell ECS could improve the price of the solution. It is expensive."
"We have concerns about the write performance. We would also like it to be easier to scale out, to add more boxes to the system. And we want improved performance, to use a next-generation NFS service."
"They need to ensure that the system will work if a site goes down."
"The troubleshooting feature of this solution needs to be improved, to allow organizations to fix issues without having to contact the support team."
"The product needs to improve CLI since commands are complex. The search option is also difficult since you must give the full path."
"If they integrated some functions, as they have on Data Domain with a cyber recovery vault, it would be ideal."
"The price of the solution could be reduced."
"The analytics could be improved."
"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."
"Dell PowerScale (Isilon) is a bit expensive compared to other products."
"We had some issues with level 1 support. We had to fight with them on repeated issues. There is room for improvement in level 1 support."
"It is a bit higher priced than some of the other systems."
 

Pricing and Cost Advice

"It's a lease-based model, so it's capacity-based. We already negotiated the price a lot, but we're still doing that with Dell because somehow the product was not installed successfully, so there was a lot of struggle in the distributor territory between Dell and the environment itself. I would give the solution a 6 out of 10 for the pricing. There's a little room for improvement."
"We are not paying for the license at this stage."
"If I remember correctly, Dell ECS is an appliance, so if you buy Dell ECS, you also have to buy the hardware, while IBM is standalone software, so you can buy IBM as software only without needing to buy the hardware. On a scale of one to five, I'm rating the pricing for Dell ECS a four."
"It is an expensive solution. There is a need to make yearly payments towards the licensing costs attached to the product."
"The price of Dell ECS should be reduced."
"The solution's cost is quite reasonable."
"We initially purchased all of the licenses at the same time."
"Dell ECS is a cost-effective solution."
"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."
"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."
"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 solution is expensive; it is not the cheapest solution out there. If you look at it from a total cost of ownership perspective, then it is a very compelling solution. However, if you're looking at just dollar per terabyte and not looking at the big picture, then you could be distracted by the price. It is not an amazing price, but it's pretty good. It is also very good when you consider the total cost of ownership and ease of management."
"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"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."
"It is a really expensive solution."
"This solution is priced slightly higher than others on the market but does offer good quality. With this solution's data reduction and compression, we were able to purchase less. Costs have dropped because of the data rate of compression and deduplication."
