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.

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

"Dell PowerScale (Isilon) has powerful security, which makes it a very reliable storage solution for our content, and also the support and observability of our system; the call home feature is fantastic because when it presents an issue, Dell automatically opens a ticket regarding any warnings or alerts, allowing us to have a complete view of our system's health."
"Dell PowerScale (Isilon) helps improve the way the organization functions through massive scalability, high performance, a single file system, high availability and reliability, flexible protocols, support for NFS, SMB, HDFS, strong security, cloud integration, efficiency, data protection, snapshot, queue, and sync queue, optimized for unstructured data."
"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."
"PowerScale helps our clients consolidate data storage and multiple applications onto a single platform for easier manageability."
"The most valuable feature for me is SyncIQ."
"Certainly, we have seen return on investment and peace of mind, especially with our two clusters that are linked together, where one is a disaster recovery solution for the other."
"The stability of the solution is good."
"I assess the stability and reliability of Dell PowerScale as top-notch, as the only issues we have ever had are just failed drives, which is to be expected."
"We feel that NetApp gave us a platform (base) which could clearly arrange all our files and volumes."
"Integration with other NetApp solutions and merging them is manageable."
"We get our data faster and it's very reliable; we don't go down."
"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."
"The solution is stable."
"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."
"As opposed to cloud, we have full control over security, use, who uses it. We own a number of different companies, so we can partition however we want."
"It gave us a platform which could clearly arrange all our files and volumes."
 

Cons

"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."
"I would appreciate seeing improvements in Dell PowerScale, particularly because it has been weak with small file writes."
"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."
"Perhaps if there was a local chatbot built within the system or on the dashboard where we could directly ask for anything on the OneFS, it could help us."
"The solution isn't suitable for small environments or small customers."
"Always, there is room for improvement in terms of cybersecurity, as new challenges are continually emerging in the market."
"If I could improve one thing on Dell PowerScale (Isilon), it would be better object storage as it recently breached into S3, and that capability could be broadened."
"One downside of Dell PowerScale (Isilon) is that it is really complicated to configure."
"I'm not sure how easy it is to use on the cloud versus on-prem."
"The documentation could be improved."
"I'm not sure how easy it is to use on the cloud versus on-prem. If they have different user experiences, they should work to make the two as similar as possible to make it easy for a user to understand both even if they only deal mainly with one."
"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."
"The price could be lower."
"They need a little more technical people in Akola. Most of the NetApp people are in Bangalore, Mumbai, or Delhi, but there are very few in Akola. I think NetApp has few technicians in Akola because they mostly rely on partners to service this area."
"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."
"This product is probably one of the most complex to set up on the market."
 

Pricing and Cost Advice

"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"Price was also a significant factor in our decision to go with PowerScale. The team at EMC, now Dell EMC, came through with a highly competitive offer that tipped the scales towards their solution. There was only one other solution around the same price point, but it could not match PowerScale on features. That other solution is no longer on the market."
"The pricing is excellent."
"It is an expensive solution."
"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."
"Dell PowerScale (Isilon) is an expensive solution."
"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."
"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."
"The product is costly."
"It is an expensive solution."
"In general, I am pleased with the pricing, though it is a little high."
"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."
"NetApp Private Storage is cheaper here in India compared to other solutions, such as Dell."
"We negotiate whatever deal we can get on the type of storage that it is, but it's totally under our control,."
