Flexibility and reliability have supported seamless data growth
I cannot think of anything to improve about Dell PowerScale (Isilon). The hardest challenge we have is due to how we've bought things over time. The way that we moved to the PowerEdge platform for the newer systems creates a scale problem as I still buy the older style systems, which are more dense storage. They're different chassis, so the problem we run into in the data center is the depth of the actual equipment. The newer equipment, if we buy an FX910 or a 900, it's a lot shorter in scale than if I buy an 83,000, which is much bigger. This makes it more complicated for deployment.

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 solution is extremely easy to manage. This is its most valuable feature."
"The reliability and stability of Dell PowerScale (Isilon) is good, with no downtime."
"The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product. This solution has also had a positive impact on our employees' productivity because it reduces the amount of admin that our staff needs to handle."
"On a scale of one to ten, with one being worst and ten being best, I would rate Dell PowerScale (Isilon) a ten."
"The features of Dell PowerScale (Isilon) that I prefer the most include some of the newer technologies that are on it, which would include SmartSync and the ability for the data mover to continue to make incremental changes."
"Its most valuable feature is the DR capabilities replication."
"This has been a valuable solution for our business overall. It offers business continuity and replication features."
"It has allowed us to have more consistent quality controls. It has also allowed us to expand the number of servers in clients processing and accessing data, allowing us to get a lot bigger projects out the door."
"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

"The cost of Dell PowerScale is currently high and there is room for improvement."
"The UID mapping and how to configure mapping-related things is a struggle."
"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."
"Dell PowerScale's deployment is not easy."
"Sometimes, it takes too long to set up everything. That's something I would want them to improve."
"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."
"There is room for improvement with the updates. It can take a significant amount of time to do a major OS update. However, even though it takes multiple reboots, the cluster stays up. If we want to apply a newer version of the OS, we have to roll back some of the patches so that we can upgrade. It requires a few reboots just to do that. The cluster doesn't come down, everything is still running, but it's time-consuming, at times."
"Pricing is an issue. It's quite expensive for the amount of storage we have."
"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."
"Pricing for this solution is reasonable."
"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."
"Our company finds the pricing high, but it decreases over time."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"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."
"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."
"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."
"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."
