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.

Open-source with great disk management and task synchronization
The system itself allows you to add any feature. The only bad thing is that this maybe depends on FreeBSD, and sometimes finding documentation is difficult. For example, we knew that previous versions automatically enabled the Linux kernel, yet with the recent version, this was no longer the case. Now, there was the possibility of being able to create Debian-based jails, and finding the documentation was not easy or fast. That said, in the end, we succeeded. If you find the documentation, it is always incomplete and fragmented.

Quotes from Members

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

Pros

"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."
"The features of Dell PowerScale (Isilon) that I appreciate the most include the scale of architecture and the way it is designed, which benefit my company by providing less downtime and less overhead."
"Customer service is absolutely satisfying, rating at least nine out of ten, as they have managed previous issues well."
"The major advantages include data protection, ransomware protection, and cloud capabilities, and the primary advantage is the ability to use the entire cluster in one unified file system, which is a feature I have not observed in other products."
"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 tool comes with cheap disks and works fast for video content."
"Dell has been great with everything."
"The solution in general has allowed us to move off of multiple Windows boxes where they had huge data stores, and we migrated it to the Isilon, making it easier and more cost-effective with just one point of contact."
"The ease of use of the 'jail', the management of backups, and copies to easily create test and pre-production scenarios have speeded up the development and distribution of business apps."
"Its stability is the most valuable. It is reliable, and we don't have to worry too much about it."
"The stability is quite good; our system is in production and we have not had any problems with it, and when a drive fails, we don't really have any disruption because we can easily rebuild the disk, even if it is very large."
"The program is fast, fun to work on and easy."
"FreeNAS is much simpler and easier to use than other solutions, but we don't have the complete range of features that come with the full version."
"The fact that no data are lost when a hard drive fails is extremely reassuring, as I have had two of five drives fail at one time and no data were lost."
"It has the best storage capacity."
"It integrates well into either Windows or Linux environments."
 

Cons

"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."
"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."
"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."
"Its configuration needs to be more straightforward."
"We have issues in Brazil with the procurement of solutions because we have to check the entire market and justify the pricing to our audit institutions, making it difficult to keep with the same vendor."
"One downside of Dell PowerScale (Isilon) is that it is really complicated to configure."
"My experience with customer service and technical support has been challenging. The reason is that it is difficult to find subject matter experts around the solution."
"There are some missing features in the product, especially when our company needs to do some tape backup, and we see that the tool doesn't have integration capabilities."
"Make it easier to find out how to fix things when something goes wrong."
"They can improve the integration with PSA systems. This functionality could be better."
"FreeNAS should be better prepared for clustering."
"They should include clustering for the solution."
"If you find the documentation, it is always incomplete and fragmented."
"The support for S3 needs to be improved."
"Its support for Hyper-V clusters."
"One of my hard drives has failed and the documentation that I've been able to find has not helped."
 

Pricing and Cost Advice

"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."
"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."
"The general cost for a system like this is expensive. The total cost depends on your use case. You need to pay for every additional feature that you use."
"The platform is not cheap. However, on the software side, you can choose what you want license. So, you can start your licensing with the features that you need, then after buying the platform add some other features."
"The only drawback for us is that it's a large upfront investment. This was a huge decision for a startup company to make. It took a bit for us to get over the line on it, but we have not regretted it."
"It is a really expensive solution."
"The pricing for this solution is reasonable."
"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."
"Its price is okay. It suits our needs."
"For our configuration, we pay a little bit less than €10,000 ($12,000 USD) per year."
"We use the free version of the program."
"Its licensing cost is based on the hardware capacity."
