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.

Cost savings and efficient data management improve operations but support quality varies

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. I always had to get it escalated or ask for someone specifically because those other people would just read knowledge-based articles that I had already done myself. Quest QoreStor does not work with any backup software, server, or storage hardware. It has the hardware compatibility list, and you need a specific number of IOPS, so it needs to run on decent hardware at least to have enough input-output operations. Otherwise, the setup result will be canceled. I'm not too sure if there are still physical appliances, but when I first started, we had some customers with a physical Quest QoreStor appliance, and it would only run on certain hardware. It doesn't work with every backup program. For example, Veritas Backup Exec is incompatible, but Veeam is compatible, and V Ranger is compatible as well. I didn't even know that Quest QoreStor has any static AI and behavioral AI technologies.

Quotes from Members

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

Pros

"ONTAP has improved my organization by lowering budget costs. Deduplication, compression, compaction, SnapMirror, SnapWall, the transaction happens from one to the other. It's serving our needs just as expected."

"This solution saved approximately 50% to 60% of time."

"Queries are being completed in less time, and we have seen a three times improvement when it comes to running a query; if a query used to take an hour, now it takes 10 to 20 minutes."

"The single management plane in NetApp ONTAP, with BlueXP and Cloud Insights, is valuable. It allows us to see globally all physical and cloud-hosted systems within one management plane, which is a big plus."

"I choose NetApp ONTAP over their competition because NetApp ONTAP and its devices are very powerful, with excellent scalability and efficiency in input/output operations per second."

"NetApp ONTAP enables us to deliver services to customers predictably, which is crucial in our line of business."

"The ability to do online upgrades in a clustered setup is absolutely crucial, and I extensively use new features such as replication and backups for certain cloud features in the enterprise."

"NetApp ONTAP has significantly improved our customer satisfaction and enabled faster service delivery at my organization."

More NetApp ONTAP pros

"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."

"The extreme compression of data is a big thing for us. We were looking for an online backup solution, and QoreStor is very good in terms of data compression. It helps us minimize the required storage in the Blob Storage environment."

"QoreStor has helped us to reduce our backup storage requirements on-premises, and we've been using the same devices for quite a while, so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution."

"Quest QoreStor definitely saved us money."

"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."

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

"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."

"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."

More QoreStor pros

Cons

"The way you attach, move, migrate, and access LUNs is complicated, and if you do not know how to do it, it can be a great problem for your IT environment."

"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."

"I could see the GUI being a little bit more refined, the presentation layer being a little stronger, a little less sluggish."

"I would like it to be more user-friendly. When you open the main dashboard, anyone should be able to know exactly what is going on, even without a tech background. Minimal training should be required."

"It should have the ability to be very agile and release more cloud-centric products as compared to some of its competitors."

"The first year was not a great time, between a lot of email exchanges, a lot of escalations, etc."

"I need to be able to validate how the host is performing from the storage, as I am concerned about the host performance and storage connectivity to the host."

"The price could be lower."

More NetApp ONTAP cons

"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."

"They need to increase their maximum capacity."

"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable. You have to have a connection to support to install."

"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable."

"The ransomware protection of QoreStor could use improvement."

"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."

"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something."

More QoreStor cons

Pricing and Cost Advice

"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."

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

"It is cost-effective for the benefits you get."

"Because of the dedupe technologies and Data ONTAP servers, we have saved 20% on hardware. This is a lot of money for us."

"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."

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

"The data compression and deduplication have kept us from buying more disks these past three years."

"It has been cost-efficient. Compared to our legacy Dell infrastructure, we have realized cost savings. It is good."

More NetApp ONTAP pricing and cost advice

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

"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."

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