Unified file sharing has simplified multi-tenant access and has delivered seamless data replication

Dell PowerScale (Isilon) includes its replication features; when we decommissioned our old Isilon cluster, we migrated all of the data to a new cluster, and it was pretty seamless. All you have to do is create the certificates and make those certificates available to the target cluster, then initiate a few jobs. The inter-cluster replication feature, called SyncIQ, allows you to set up all of the jobs and move your data entirely, either timely or all at once. Another suitable feature is the ability to back up your directories; you can take snapshots for all of your directories, and in fact, I believe you can take around a thousand snapshots for a single directory. The inter-replication, geo-replication is one feature. Dell provides a variety class of hardware suitable for your workloads, meaning if your data is just lab and not critical, you don't have to spend much on the hardware; conversely, if your data is mission-critical, you can buy a high-performance node from Dell. Additionally, you can span Dell PowerScale (Isilon) cluster to a large number of nodes, and code upgrades are pretty smooth because all protocols will be upgraded under a single piece of code. Since it provides a single file system that spans across the nodes, you don't have to worry about that directory structure being separately created on individual nodes, making it a fitting solution for a data lake solution because you can access the same data from multiple protocols.

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

"The single pane of glass for both IT and for the end-user is a valuable feature. On the IT side, I can actually control where things are stored, whether something is stored on solid-state drives or spinning drives... The single pane of glass makes it very easy to use and very easy to understand. We started at 100 terabytes and we moved to 250 and it still feels like the exact same system and we're able to move data as needed."

"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."

"The solution's most valuable features are scalability and flexibility."

"Prior to Isilon, we had to access data from multiple different platforms, and this solution offers unified storage and the ability to consolidate and migrate data, which was a big step forward and allowed us to cut costs by eliminating multiple platforms and putting it all on one array."

"Customer service has been really good."

"Regarding stability, I find no lagging, crashing, or downtime with Dell PowerScale (Isilon), and it is a highly scalable, stable, and reliable solution that I have experienced."

"I don't have to rebuild the cluster to add a node."

"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."

More Dell PowerScale pros

"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."

"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."

"They have the scalability that we need, that we ask for, and I think it is a very, very good solution."

"Very stable and very scalable."

"We get our data faster and it's very reliable; we don't go down."

"In terms of quality and uptime, it is the thing to have."

"NetApp is faster than other storage brands."

"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."

More NetApp Private Storage pros

Cons

"I would like to see improvements in data deduplication. In our environment, the deduplication ratio is approximately 2 or 2.3 to 1, so I believe there can be enhancements in this area."

"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."

"Data storage performance needs to be improved."

"My advice for others looking into using Dell PowerScale is that it is not cheap, so make sure that your use case matches the need for that type of technology; do your research."

"The analytics could be improved."

"It would be nice to see tools like Superna Eyeglass built into PowerScale."

"There should be some enhancement where Dell PowerScale can have block level functionality or block storage kind of functionality."

"An example of something that is problematic at the moment or that I would want to see improved is that there needs to be further delineation between access zones and settings."

More Dell PowerScale cons

"The one thing I've noticed with NetApp when you buy hardware and you can use it for a while and then you have to get new hardware."

"There is room for improvement in the support. It has been a problem for our team."

"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."

"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."

"I would like to have the Active-Active feature. Some competitors already have it. I would like NetApp to add it to stay competitive."

"The solution could improve by having better support experts. For example, they do not have clear instructions on configuration."

"I'm not sure how easy it is to use on the cloud versus on-prem."

"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."

More NetApp Private Storage cons

Pricing and Cost Advice

"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."

"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 an expensive product with a high storage capacity suitable for large data requirements."

"Pricing for this solution is reasonable."

"The pricing for this solution is reasonable."

"The solution's licensing cost varies based on capacity and performance 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."

More Dell PowerScale pricing and cost advice

"The price could be lower."

"NetApp Private Storage is cheaper here in India compared to other solutions, such as Dell."

"In general, I am pleased with the pricing, though it is a little high."

"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."
