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

"The performance, overall, is quite impressive."
"PowerScale allows us to manage storage without managing RAID groups or migrating volumes between controllers. It has really simplified things. We're not having to worry about the underlying infrastructure. That takes care of itself. We just worry about the data. It's really easy for deploying and managing storage at the petabyte scale."
"The solution in general has allowed us to move off of multiple Windows boxes where they had huge data stores, and we migrated it to the Isilon, making it easier and more cost-effective with just one point of contact."
"The major advantages include data protection, ransomware protection, and cloud capabilities, and the primary advantage is the ability to use the entire cluster in one unified file system, which is a feature I have not observed in other products."
"What I like the most about Dell PowerScale (Isilon) is that the storage capacity is very high."
"Dell PowerScale overall is easy to use."
"The most valuable feature of the solution is the unlimited scalability. The tool has high availability and high storage capacity."
"The solution's flexibility for supporting various data workloads while keeping them protected is great."
"At the moment, we are extensively using SnapMirror."
"It gave us a platform which could clearly arrange all our files and volumes."
"The solution is stable."
"NetApp is faster than other storage brands."
"The most valuable feature is integration."
"We get our data faster and it's very reliable; we don't go down."
"If your company has the budget for NetApp Private Storage I would recommend it."
"Disaster recovery. And I like the security very much. I think they have the needed options for security. Can manage NPS using the same tools and process that we use today."
 

Cons

"Pricing is an issue. It's quite expensive for the amount of storage we have."
"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 UID mapping and how to configure mapping-related things is a struggle."
"I have escalated questions to the technical support team of Dell, and I find the support center to be very poor compared to what it was during EMC's time."
"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."
"The solution's rate structure or rate redundancy needs to be improved."
"The pricing could be reduced."
"Dell PowerScale (Isilon) could be improved, particularly the UI, which could use some polishing as far as ease of use for the customer."
"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."
"This product is probably one of the most complex to set up on the market."
"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."
"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."
"I think that it should work better with Microsoft solutions, more integrated with Microsoft. We also need integrated NAS and block storage."
"There is room for improvement in the support. It has been a problem for our team."
"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."
"The users find the new version's GUI complicated to use."
 

Pricing and Cost Advice

"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 pricing for this solution is reasonable."
"It is an expensive solution."
"Pricing for this solution is reasonable."
"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 only drawback for us is that it's a large upfront investment. This was a huge decision for a startup company to make. It took a bit for us to get over the line on it, but we have not regretted it."
"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."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"The price could be lower."
"It is an expensive solution."
"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."
"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."
"We negotiate whatever deal we can get on the type of storage that it is, but it's totally under our control,."
