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.

Has supported continuous broadcasting with reliable performance and consistent operations
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

"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."
"The initial setup was easy because we received support from their partners, which enabled us to install it without difficulty."
"The solution allows me to use SSMDS to store data for end users and share it within different locations."
"This has been a valuable solution for our business overall. It offers business continuity and replication features."
"I can certainly recommend PowerScale for mission-critical workloads, it is a powerful but simple platform with little administration overhead."
"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."
"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."
"Eyeglass is used to monitor for malware, which is very useful for us."
"In terms of quality and uptime, it is the thing to have."
"NetApp has really added a lot of features over the years to improve the product and performance. They can do things now like control ingress. They can control egress."
"NetApp has its own dedicated operating system, so it will not be affected by any wireless piggybacking or malware. That's the beauty of NetApp's operating system."
"For recording and stability, NetApp Private Storage is the best."
"NetApp has its own dedicated operating system, so it will not be affected by any wireless piggybacking or malware."
"Integration with other NetApp solutions and merging them is manageable."
"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."
"NetApp is faster than other storage brands."
 

Cons

"Because of the magic that it does 'under the hood,' it is very difficult to find out within the system where all your storage is going."
"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."
"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."
"The support offered by the product is an area of concern where improvements are required."
"The tool's support team and the way the cases are handled by the product's technical support team are both areas of concern where improvements are required."
"Version upgrades and patches take a long time to complete."
"Isilon has limitations on the number of files that can be generated."
"The management and monitoring tools comprise a disparate suite of products and the roadmap is very unclear. We've got four different products that look after the Isilon, management-wise, and it's a bit of a mess."
"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."
"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."
"The documentation could be improved."
"I would like to have the Active-Active feature. Some competitors already have it. I would like NetApp to add it to stay competitive."
"We had to write a number of custom tools or scripts ourselves to use it as a staging area between our on-premises datacenter and our cloud installation."
"They need a little more technical people in Akola."
"There is room for improvement in the support. It has been a problem for our team."
"I'm not sure how easy it is to use on the cloud versus on-prem."
 

Pricing and Cost Advice

"The solution's licensing cost varies based on capacity and performance requirements."
"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."
"Our company finds the pricing high, but it decreases over time."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"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."
"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 price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"Dell PowerScale (Isilon) 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,."
"It is an expensive solution."
"The product is costly."
"The price of NetApp Private Storage is similar to other solutions. There is typically an annual license required for this solution."
"The price could be lower."
"In general, I am pleased with the pricing, though it is a little high."
"NetApp Private Storage is cheaper here in India compared to other solutions, such as Dell."
