Operates seamlessly and minimizes downtime while meeting enterprise file share demands
The features of Dell PowerScale (Isilon) that I appreciate the most include the scale of architecture and the way it is designed. These features benefit my company by providing less downtime and less overhead. While I have not calculated an exact number regarding the reduction in downtime, we have always been using the product, so we have no baseline to compare it to. However, it is a very good product. Dell PowerScale (Isilon) scales very well with the growing needs of my company.

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

"PowerScale is one of those things that will grow in your environment; once you start it with one thing, you'll learn that it can do much more, very quickly."
"This solution offers flexibility in supporting various data workloads and is very easy to work with, making it our go-to solution for all data storage."
"Dell PowerScale is a scalable solution. It allows non-disruptive upgrades and maintenance of the system."
"The fact that the business saw a noticeable improvement in performance the day we switched over was a game-changer, not to mention the ability to seamlessly swap out the nodes to move from the older Isilon platform to Dell PowerScale, with no data migration, making everything seamless, done behind the scenes, and users only noticing the jump in performance."
"The solution's scalability is very good."
"The reliability and stability of Dell PowerScale (Isilon) is good, with no downtime."
"Of all the components in our IT system, it's probably the least troublesome."
"The stability of the solution is good."
"The program is fast, fun to work on and easy."
"What I like about it is that I can work on it from any computer or any device. The initial setup is very simple. The setup wizard is really helpful."
"Its stability is the most valuable. It is reliable, and we don't have to worry too much about it."
"The solution has been very stable so far."
"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."
"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."
"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."
"After using FreeNAS I will never spend money for commercial products like Dell or 3Par."
 

Cons

"The solution can be a bit complex for those not well versed in the technology."
"Dell PowerScale can improve on its multi-tenant part because as a service provider, we have bigger clusters in data centers where we can serve multiple customers and grant them dedicated management points and automation features that can be managed in a multi-tenant environment."
"The initial setup for this solution is complex."
"The cost of Dell PowerScale is currently high and there is room for improvement."
"My experience with pricing, setup cost, and licensing for Dell PowerScale has been expensive."
"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."
"The pricing is expensive, but I think it's a fair value because it does manage itself."
"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."
"One of my hard drives has failed and the documentation that I've been able to find has not helped."
"FreeNAS should be better prepared for clustering."
"They can improve the integration with PSA systems. This functionality could be better."
"Make it easier to find out how to fix things when something goes wrong."
"They should include clustering for the solution."
"The latest version of the dashboard doesn't work as good as the previous version. Sometimes we change our dashboard back to the previous version because the latest version just doesn't work as good."
"Its support for Hyper-V clusters."
"The one thing that I find difficult to do which is very time-consuming is that I like to have a backup of the important files."
 

Pricing and Cost Advice

"The price of Dell PowerScale (Isilon) is reasonable."
"Pricing for this solution is reasonable."
"Our company finds the pricing high, but it decreases over time."
"Dell PowerScale is expensive on the start-up side but we can recoup those costs quickly by not having to reapply the savings to other equipment."
"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."
"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."
"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 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 free version of the program."
"For our configuration, we pay a little bit less than €10,000 ($12,000 USD) per year."
"Its price is okay. It suits our needs."
"Its licensing cost is based on the hardware capacity."
