Simplified data management, tremendously reducing our users’ cognitive overhead
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. You can either access a file because it can be access by anyone in the organization, or you cannot at all. There is no in-between. HTTP is not considered a first-class data access protocol, so the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply. However, with the recent introduction of S3 starting from OneFS 9, I believe the necessary plumbing is already there for HTTPS to also be elevated to a first-class protocol in the future because both protocols sit behind a web server under the hood. It does not sound like it would be too complicated to implement, but it would be a valuable feature and it is currently missing.

Well-suited for virtualized environments and highly stable solution
We are in a VMware Intra environment, so we are utilizing NetApp Storage for our virtualization infrastructure NetApp offers multiple features that we utilize for our projects. At the moment, we are extensively using SnapMirror Flex. There is room for improvement in the support. It has been a…

Quotes from Members

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

Pros

"The stability of the solution is good."
"Since it can scale so easily, as long as I have money to buy more nodes, I can grow it as big as I need to. That is important in our business. As sequencing technologies continue to evolve, and as those technologies evolve, the amount of data generation never gets smaller. It just always seems to get bigger. This is one of the absolute key aspects: We can grow on demand without having to forklift stuff."
"The best thing is that it works. We don't have to maintain it too much; we usually upgrade once a year."
"The tool comes with cheap disks and works fast for video content."
"The most valuable feature of Dell PowerScale is its scalability."
"The most valuable feature is its single space of storage."
"I don't have to rebuild the cluster to add a node."
"Dell PowerScale is a scalable solution. It allows non-disruptive upgrades and maintenance of the system."
"NetApp is faster than other storage brands."
"It gave us a platform which could clearly arrange all our files and volumes."
"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."
"Integration with other NetApp solutions and merging them is manageable."
"The solution is stable."
"Very stable and very scalable."
"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."
"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."
 

Cons

"The product needs to improve CLI since commands are complex. The search option is also difficult since you must give the full path."
"Dell PowerScale (Isilon) could improve the load distribution capability. For example, in some cases, the system load is not distributed automatically on all the nodes but is concentrated only on one. You have a peak request on only one node and the others don't do anything."
"The solution's rate structure or rate redundancy needs to be improved."
"We had some issues with level 1 support. We had to fight with them on repeated issues. There is room for improvement in level 1 support."
"That said, for the other security features, it would be helpful if Tenable - and I know it's outside the scope of this question itself - had Isilon-specific plugins."
"Dell's customer service needs improvement."
"It is a bit higher priced than some of the other systems."
"Improvements could be made on the object storage side."
"It is not the fastest storage solution."
"The solution could improve by having better support experts. For example, they do not have clear instructions on configuration."
"There may actually be so many features that the end-user gets lost in the volume."
"I would like to see the GUI management simplified in the next release."
"The users find the new version's GUI complicated to use."
"I think that it should work better with Microsoft solutions, more integrated with Microsoft. We also need integrated NAS and block storage."
"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."
 

Pricing and Cost Advice

"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"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."
"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."
"This solution is priced slightly higher than others on the market but does offer good quality. With this solution's data reduction and compression, we were able to purchase less. Costs have dropped because of the data rate of compression and deduplication."
"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 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."
"The pricing for this solution is reasonable."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"The product is costly."
"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 could be lower."
"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."
"It is an expensive solution."
