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.

They can make more solutions for cloud integration in NetApp Private Storage. It should be easier to use the cloud S3 integration, maybe from a NetApp interface, where users can choose the type of storage before sending to S3. I would like to see more audit and performance logs via cloud integrations and ONTAP. Without the need for separate software.

Quotes from Members

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

Pros

"Dell PowerScale includes a wealth of features that are important from a security and recovery perspective."
"I assess the stability and reliability of Dell PowerScale (Isilon) as perfect, as we haven't had any hiccups with it so far."
"Ability to scale the number of nodes without having to build additional clusters."
"The technical support has been excellent. I would give them a ten out of ten for support."
"The product's scalability feature is super easy to use."
"I rate Dell PowerScale (Isilon) a ten out of ten, and we continue to keep buying it."
"Dell PowerScale (Isilon) is a platform that is very easy for teams to work with."
"Overall, Dell PowerScale (Isilon) has made the management of the data and networks easier."
"Very stable and very scalable."
"Its flexibility and ability to configure volumes is its most valuable aspect; I have no problem configuring the product for different kinds of use cases and configuring throughput or configuring some kind of logical volumes and so on."
"NetApp has its own dedicated operating system, so it will not be affected by any wireless piggybacking or malware."
"The most valuable feature of NetApp Private Storage is out-of-the-box integration with the SAN switches. They are much easier compared to Dell solutions. Additionally, the connector that comes with the solution that allows connection back to the Cisco SAN switches is very good. In Dell, I would need to use an FCIP or CIP port that is required."
"In terms of quality and uptime, it is the thing to have."
"It gave us a platform which could clearly arrange all our files and volumes."
"They have the scalability that we need, that we ask for, and I think it is a very, very good solution."
"The most valuable feature is integration."
 

Cons

"A recent development is, that there's a key feature coming out in OneFS 9.3, however, when you then try to get to 9.3 or 9.4 of the OneFS, it's been pulled from the download of the Dell website and we're referring back to 9.2.1 as the target code."
"The solution isn't suitable for small environments or small customers."
"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[...]the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply."
"We have had issues with internal load balancing between some of the shelves. That is an ongoing issue that support is trying to address."
"One downside of Dell PowerScale (Isilon) is that it is really complicated to configure."
"The deployment of Dell PowerScale (Isilon) is not really complex but depends on the hardware deployment."
"I'd like to see more Iceland products in the cloud so that we can port our data into different environments if needed. I would also like to see a virtual appliance or software-defined Iceland product."
"The portal is really complicated to figure out features and functions, and it could be easier to navigate."
"I'm not sure how easy it is to use on the cloud versus on-prem."
"The users find the new version's GUI complicated to use."
"There is room for improvement in the support. It has been a problem for our team."
"The solution could improve by having better support experts. For example, they do not have clear instructions on configuration."
"This product is probably one of the most complex to set up on the market."
"I would like to have the Active-Active feature. Some competitors already have it. I would like NetApp to add it to stay competitive."
"They can make more solutions for cloud integration in NetApp Private Storage. It should be easier to use the cloud S3 integration, maybe from a NetApp interface, where users can choose the type of storage before sending to S3."
"NetApp Private Storage is still integrated into the ISCSI connectivity and the FC protocol. I would recommend them to migrate to the FCIP because the SAN switches are moving further to an FCIP, and are scaling out of the ISCSI connectivity. Sooner or later, that will be an issue for NetApp Private Storage. An NFCIP should be available to them moving three years down the line."
 

Pricing and Cost Advice

"It is an expensive solution."
"The pricing is excellent."
"The price of Dell PowerScale (Isilon) is reasonable."
"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."
"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."
"It is a really expensive solution."
"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 solution's licensing cost varies based on capacity and performance requirements."
"In general, I am pleased with the pricing, though it is a little high."
"The price could be lower."
"NetApp Private Storage is cheaper here in India compared to other solutions, such as Dell."
"It is an expensive solution."
"We negotiate whatever deal we can get on the type of storage that it is, but it's totally under our control,."
"The price of NetApp Private Storage is similar to other solutions. There is typically an annual license required for this solution."
"The product is costly."
