Senior Storage Engineer at Shell

Data management and availability improve operations, but cost and support need attention

For snapshots, there should be something similar to a recycle bin. When someone mistakenly deletes a snapshot, it should be stored for about two days before disappearing from the system. Regarding storage optimization, when purchasing a 10 terabyte disk, after formatting, you can only use approximately 8 terabytes. They should improve this so users can utilize 90% instead of 80% of the disk space. 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. Comparing NetApp ONTAP to other solutions such as EMC, the cost of contract renewals and warranties is relatively expensive. They should extend their renewal window beyond the current six months to one year options. A longer warranty period of two years for new systems, controllers, or filers would be beneficial. Overall, they should reduce subscription costs for businesses.

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

"We use a lot of SnapVault and SnapMirror features for disaster recovery and daily backups to meet SLAs."

"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."

"The solution is certainly reliable."

"The product is good at deduplication. Also, the new automation feature is good, as it saves us a lot of time."

"Over the last five years of implementing a MetroCluster ONTAP, we've been able to improve and keep a high availability for our organization."

"If you lose connectivity, it has one-sided redundant connectivity on the back-end for shelves, which is good."

"It's extremely reliable, very easy to manage. I've been able to reduce the number of people I have managing the storage systems because of the software."

"We save a lot because of the deduplication and compression."

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."

"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."

"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."

"Quest QoreStor is very stable compared to our previous solution."

"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."

"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."

"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."

More QoreStor pros

Cons

"There is room for improvement in the stability. They have been trying to become simpler, and as a result, there have been road bumps along the way. I have personally experienced this."

"I would like to see more integration of the features with the CIFS and SMB Protocols. We also want integration with iSCSI."

"The vendor diagnostics, which allows for movement from one vendor to another vendor using the application technology that is available. It should be able to talk to any vendor, not just NetApp to NetApp. We should be able to replicate the data, so the next feature should not be vendor specific."

"Some of our DR tests have been not successful, so it's been a little troubling."

"The price could be lower."

"ONTAP's GUI does not encompass all the features available in the CLI."

"Because most of us were new to the product, the initial setup was a bit cumbersome. Once we were trained, it was fine."

"I wish tech support would be better. I wish I could talk to somebody more easily and qualified, because this is the way it is supposed to be."

More NetApp ONTAP cons

"There can be some kind of monitoring solutions to alert users to issues with the appliance or software, making it easy for customers to monitor their systems in the field."

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

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

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

"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 setup of the software is definitely not the easiest thing in the world."

"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."

"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something. So that when we don't do a backup, we want the QoreStor to stay offline. It would be a nice feature to have."

More QoreStor cons

Pricing and Cost Advice

"The product is a bit expensive."

"This solution has helped our organization reduce our overall cost of storage. We're part of the NetApp OnDemand, where we lease it. Also, it doesn't take as many people to administer the solution as some other products."

"They could reduce the price."

"With the duplication and compression, we have been about a one and half to two times savings since we are not running all-flash."

"NetApp ONTAP is a pricey product, but you pay for what you get. I rate NetApp ONTAP a five out of ten for its pricing."

"This solution helped our organization reduce our overall cost of storage. Because idle data which was residing on high cost tiers, once we sifted the ONTAP, we were able to scale and place it where it should be, then offload the data which was unnecessary to different locations."

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

"When you purchase NetApp for the first time they will provide you with the standard license, or a premium license, and even a standard bundle solution license."

More NetApp ONTAP pricing and cost advice

"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."

"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."
