Storage Platform Engineer at Expedia Group
Unified file sharing has simplified multi-tenant access and has delivered seamless data replication
Dell PowerScale (Isilon) includes its replication features; when we decommissioned our old Isilon cluster, we migrated all of the data to a new cluster, and it was pretty seamless. All you have to do is create the certificates and make those certificates available to the target cluster, then initiate a few jobs. The inter-cluster replication feature, called SyncIQ, allows you to set up all of the jobs and move your data entirely, either timely or all at once. Another suitable feature is the ability to back up your directories; you can take snapshots for all of your directories, and in fact, I believe you can take around a thousand snapshots for a single directory. The inter-replication, geo-replication is one feature. Dell provides a variety class of hardware suitable for your workloads, meaning if your data is just lab and not critical, you don't have to spend much on the hardware; conversely, if your data is mission-critical, you can buy a high-performance node from Dell. Additionally, you can span Dell PowerScale (Isilon) cluster to a large number of nodes, and code upgrades are pretty smooth because all protocols will be upgraded under a single piece of code. Since it provides a single file system that spans across the nodes, you don't have to worry about that directory structure being separately created on individual nodes, making it a fitting solution for a data lake solution because you can access the same data from multiple protocols.

An entry-level, flash-based storage system designed for enterprise-class applications
It took significantly longer to set up the solution with Huawei compared to other options. But when creating servers for VMware virtualization in one data center, it was a relatively quick process. The Huawei's solution, even with the assistance of an engineer, took more than one month, possibly extending to two months. Chinese engineers were involved in the process, which contributed to the delays.

Quotes from Members

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

Pros

"The maintenance is very good, and the deployment is straightforward as well."
"The most valuable feature of the solution is the unlimited scalability. The tool has high availability and high storage capacity."
"Dell PowerScale is a scalable solution. It allows non-disruptive upgrades and maintenance of the system."
"Dell PowerScale's performance is good."
"This has been a valuable solution for our business overall. It offers business continuity and replication features."
"PowerScale allows us to manage storage without managing RAID groups or migrating volumes between controllers. It has really simplified things. We're not having to worry about the underlying infrastructure. That takes care of itself. We just worry about the data. It's really easy for deploying and managing storage at the petabyte scale."
"The solution provides massive performance, scalability, efficiency, and ease of management."
"I appreciate the high-availability data storage feature of Dell PowerScale the most, as it has benefited my organization by improving storage and collapsing technologies, making it easier for the users and aligning with our digital transformation initiatives by collapsing a large environment to a small footprint."
"It has many options for scalability, and it is stable."
"The storage capacity is really one of the most valuable features. Also, the GUI is very friendly and the switches gives high performance. The technology used in storage is RAID which as helped us a lot to expand and store various items ."
 

Cons

"If they integrated some functions, as they have on Data Domain with a cyber recovery vault, it would be ideal."
"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."
"I would like to see Dell PowerScale (Isilon) improved by enhancing the user interface, OneFS, to make advanced conversation and troubleshooting more specific, upgrade and batch management, providing deeper built-in analytics for performance and capacity planning."
"The analytics could be improved."
"We lost our technical sales reps about two years ago. We haven't gotten one assigned to us and we'd love to have one."
"Backward compatibility is something Dell PowerScale (Isilon) could work on."
"I would make Dell PowerScale (Isilon) better by improving SmartSync in the graphical user interface. Currently, everything has to be done through the command line, and I prefer having a graphical interface."
"Always, there is room for improvement in terms of cybersecurity, as new challenges are continually emerging in the market."
"The handling of data deletion and bulk servers setup could have been more straightforward and easier when dealing with data removal or setting up servers. I believe Huawei could enhance their solutions, especially managing storage, to provide a better experience for customers."
"The call charges and the management cost should be more friendly. They can also include monitoring and management."
 

Pricing and Cost Advice

"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 price of Dell PowerScale (Isilon) is reasonable."
"Price was also a significant factor in our decision to go with PowerScale. The team at EMC, now Dell EMC, came through with a highly competitive offer that tipped the scales towards their solution. There was only one other solution around the same price point, but it could not match PowerScale on features. That other solution is no longer on the market."
"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."
"It is a really expensive solution."
"Dell PowerScale (Isilon) is an expensive solution."
"The pricing is excellent."
"It is an expensive solution."
"The installation is expensive as they often come as a comprehensive package. The design is more integrated, and everything is bundled together as part of the solution. This is what contributes to the higher cost of their solutions because when you purchase one element, it often comes with additional features and components, and you end up paying for the entire package."
"It is cheaper than other solutions."
