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

"With other vendors, we need to buy a separate license for a third-party storage, but with NetApp, you don't need to buy a license, as it will come up with the storage."
"The scalability is very good. It enables us to use different product lines within the same operating system."
"The product is good at deduplication. Also, the new automation feature is good, as it saves us a lot of time."
"We do not face any glitches or downtime."
"The initial setup was straightforward. It came in a box ready to go."
"We bought it for a couple reasons. One, it took advantage of our existing storage because we could front-end that storage. It also allowed us, through native replication, to set up a DR site, which we're working towards. And three, that DR site, in 2020, is going to the cloud. NetApp has a nice solution for that. And our production in 2022 may actually go to the cloud. So all that is already in place, no additional tools. You can use the same SnapMirror and SnapVault technology to get there."
"We have been using it for our entire environment, so we use it in file shares and in our VDI environment, at least for user data, and that has reduced our user login times by about 50 percent."
"We can do upgrades without taking it down. We have had nodes fail and people just kept working."
"Quest QoreStor is very stable compared to our previous solution."
"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."
"This software solution can be installed on many different types of hardware, which makes it very flexible. We can run it on virtual machines or virtual servers, providing convenience for solutions of varying sizes, from small to large."
"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."
"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."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
 

Cons

"They could focus on making it more user-friendly. Currently, many users need a certain level of NetApp knowledge to operate it effectively, often relying on command-line interfaces that demand IT or technology skills. While there is a GUI available through Systems Manager, a lot of management still occurs at the command line, so enhancing the GUI for better usability could be a key focus area."
"The only thing that they have to improve in NetApp is that they're still relying on padding each node in active/active in CDOT. That has to go away. They should look at the scalability on a platform level. The computer will have that one file system with multiple nodes on it. If even one node fails, any node in that cluster could take over the functionalities. But today, it absolutely relies on that active-active uncoupling it. That needs to be improved in such a way that it would be one namespace. If this node goes down, any node in the cluster should take over and run that environment."
"If the customer wants to integrate with another product they need deployment guides."
"They could maybe offer even better documentation."
"Technical support is not in person nowadays. We have to wait a long time to get an engineer."
"The initial setup is too complex. It should be one click."
"They could also improve on their ability to back up storage."
"The aggregates, in our case, are capped at about 800 terabytes. A way to alleviate that is by using a FlexGroup volume, which can exceed 800 terabytes, but that opens up a whole new set of issues for the future."
"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."
"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 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."
"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."
"The ransomware protection of QoreStor could use improvement."
"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."
 

Pricing and Cost Advice

"There are specific workloads where some vendors provide better value, but in general, NetApp has done a far better on price than other vendors."
"In the past, you didn't have to buy separate products. They were mostly included with the purchase. In the end, it's more expensive to buy it separate than together. If you are going to need it, one package at the beginning is cheaper."
"If you start narrowing down NetApp versus price point, then comparing it to the feature set and take away all the bloat that other companies will try to add on, there is no other option. It comes down to just NetApp."
"Our cost per IOP is three to four dollars, but we have a hybrid solution. Therefore, we have SSD and spinning disk running together."
"NetApp provided the features required within our cost limit."
"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."
"I rate NetApp ONTAP's pricing a seven out of ten."
"We have seen ROI as we can fit a lot more storage in one rack."
"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."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
