Unified storage has simplified secure data sharing and efficient cloning across our organization

NetApp ONTAP provides a unified storage architecture for managing both SAN and NAS protocols. The cloning functionality using NetApp Snapshots is excellent for our production to development system cloning. The clone step is straightforward, as I can select the snapshot and perform the cloning immediately. The security features in NetApp ONTAP are definitely valuable. NetApp encryption offers two levels of encryption: aggregate level encryption and volume level encryption. Without the encryption key, data cannot be accessed, which provides strong data protection. The deduplication function also works well in NetApp ONTAP.

Backup storage has shrunk dramatically with deduplication but still needs stronger security options

The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.

Quotes from Members

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

Pros

"With the NetApp Data ONTAP Cluster, we get some features that are particularly helpful. For example, we can always add to and remove nodes from the cluster. The ability to move volumes online from the storage side, from one aggregate to another aggregate, or from one node to another node, keeps up the performance which helps us a lot."

"The interface is very user-friendly. There are new features, including analytics that provide insights when you log in. The dashboard is very intuitive."

"They have very good tech support who always answers our questions and troubleshoots our issues. They're great."

"Ease of use is the most valuable feature for us."

"Technical support is good. NetApp's solution engineers are good at architecting designs which are standard, but also future thinking. I've only opened a few tickets, and they've answered my questions each time. NetApp takes less than four hours to respond."

"It's very fast, NetApp is always dependable, so if we have an issue, they're very responsive."

"You can scale the product up or out."

"It makes our organization more efficient with more scale, with the ability to tier off the storage and ensure storage is efficiently utilized so we can get rid of idle data and data that is not required, then show and prove what needs and should be used, and we do use this solution for mission-critical applications."

More NetApp ONTAP pros

"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."

"The features we use for the data deduplication are nice because we're able to back up a much larger amount of data, yet it doesn't necessarily take up that much data on the devices."

"Quest QoreStor definitely saved us money."

"QoreStor has helped us to reduce our backup storage requirements on-premises. We've been using the same devices for quite a while, and so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution. The advantage here is even if we had to retire the hardware tomorrow, the QoreStor part doesn't change. We just have to have additional hardware and put the solution back on whatever hardware we pick and it'll do the same thing."

"We need revisions and safe backup so that it could be held up in court, but deduplication and compression are the main features why we have Quest QoreStor. That's where it really shines. I use ZFS and XFS at home, and Quest QoreStor is even better."

"Deduplication is the most valuable feature. It saves us a lot of space. When we back up 100 terabytes of data, after dedupe, it only uses maybe five to six terabytes for the disk space in QoreStor."

"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."

"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."

More QoreStor pros

Cons

"With NetApp ONTAP, the technology is all there, but its management process needs some simplification."

"It doesn't scale horizontally since there are a limited number of shelves."

"There is room for improvement in areas related to hardware constraints—for example, more storage efficiency, especially in terms of deduplication."

"The cost is quite high. They need to work on making it a bit more affordable."

"The support response needs improvement, especially for P1 cases. When critical cases are raised, they should ensure they call the customer and follow up properly."

"ONTAP tech support needs some improvement, but it has improved quite a bit."

"If they could come up with some more automation, this would be helpful."

"They could make the access a bit easier."

More NetApp ONTAP cons

"The setup of the software is definitely not the easiest thing. I worked a lot with Quest engineers, especially in the early days when we were first testing it and trying it out. I actually had some of the developers working with us at one point because they were going through these point releases, and I was having trouble getting it to work in this S3-compatible situation. We got it all working eventually, but setup is definitely not the easiest thing in the world."

"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."

"The importance of support is significant to me. I was working for a service provider, and all of our customers had a Quest or warning. Sometimes the support really underperforms."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial. After everything is set up and configured, there should be a way to export the configuration. In case something happens to the QoreStor server, and we need to reinstall and configure everything, being able to import the configuration would be helpful. This feature does not currently exist."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."

"They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved."

"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."

"The air gap feature is something I'd really like to see in QoreStor."

More QoreStor cons

Pricing and Cost Advice

"Our pricing with discounts is reasonable, but it may vary for others."

"ONTAP is expensive, but most storage systems are now-a-days and everything is included with the license - there are no additional fees."

"The price point is very competitive and inexpensive compared to what you receive from other vendors in the market."

"ONTAP has helped our organization reduce its overall cost of storage (somewhere in the high millions)."

"Additional costs exist if you want a license for a feature like SnapMirror."

"The solution has helped us reduce the overall cost of storage by doing an OPEX agreement with NetApp, we are paying based on utilization. Instead of fronting 30 petabytes worth of storage, we are paying for what we're using."

"While it is going to cost a lot of money, their technologies is worth it."

"At first, it's expensive. Once you start using it, it's not that expensive. When you see all the benefits, it's acceptable. It could always be better, but you get what you pay for."

More NetApp ONTAP pricing and cost advice

"Quest QoreStor's pricing is affordable. We evaluated Veeam, a well-known company for backup solutions, but found their pricing to be quite high. Veeam's price was almost double. For us, Quest QoreStor is very affordable."

"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."

"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."

"The pricing is good. It is competitive for a managed services provider. I like the ability to pay by the terabyte, allowing for an incremental cost that we and our customers can afford, so the solution grows with the customer."
