MikaelHellström

IT Manager at Regin Dalarna

Has handled backup storage needs reliably and supports seamless upgrades

In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

N Bravi

Sales Manager at MSDSYSTEMS S.R.L.

Has simplified data protection across two locations and reduced time spent on recovery efforts

The best features DataCore Swarm offers are its scalability and the ability to truly solve many problems related to data loss and recovery. It is important because if we want to add a new code, it sets itself up from scratch, and if we want to add, for example, a 72 terabytes or petabytes node, we just drop it in, which is very easy. DataCore Swarm has positively impacted my organization through the support for my dedicated salespersons.

Calvin Hilgenstock

System Administrator at a wholesaler/distributor with 10,001+ employees

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

"The most valuable features of this solution are the rewrite speed and the nonstop services."

"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."

"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."

"We can capacity plan at a greater level than we used to."

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

"It is very easy to use, and it is very fast."

"Using this solution has made our backups more reliable."

More Pure Storage FlashBlade pros

"I find its flexibility valuable."

"With DataCore Swarm, we have transitioned from tape-based backups, which were long, to Swarm, making the process more rapid and efficient."

"The first feature is compatibility with the S3 protocol. DataCore SWARM allows you to quickly have an on-premise, robust and scalable environment that is natively compatible with the S3 protocol. The functionalities used are therefore derived from the S3 protocol, notably versioning and therefore the possibility of configuring immutability in governance or compliance mode. The object metada can be enriched with the addition of tags to subsequently enable filtering and searching. Configuring and using DataCore SWARM is simple and flexible. It is very easy to create domains, tenants and buckets for different use cases with various authentications. The cluster architecture also allows replication between different clusters at different configured levels (Cluster / Domains / ...) A web interface for browsing the content of existing buckets allows simple and rapid manipulation of certain objects such as sharing via a link or cropping a video. Finally, the physical architecture of the solution is based on an x86 server and its scale-up or scale-out evolution is very simple by adding disks or servers."

"The ability for the solution to use any new hardware quickly and without administration is a great thing in the context of hosting."

"DataCore Swarm is highly available."

"The best features DataCore Swarm offers are its scalability and the ability to truly solve many problems related to data loss and recovery."

"The dedupe and compression are pretty extreme. On disk, we're getting dedupe rates of up to 65 percent of data and compression of 34 percent. When you go to the cloud, it's more like 76 percent for dedupe and almost 50 percent for compression."

"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."

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

"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."

"I would rate QoreStor a ten out of ten for what it offers for the price."

"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."

"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."

More QoreStor pros

Cons

"They need better integration with public clouds along with a better hybrid solution."

"I want efficiency. FlashBlade doesn't have efficiency now."

"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."

"I would like to see more deduplication."

"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."

"The features provided for SMB customers are limited."

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

"I would like to see better integration."

More Pure Storage FlashBlade cons

"The main issue currently is the hard installation process."

"The solution needs simpler architecture."

"The pricing can definitely be better."

"The product currently requires a significant number of servers to start. There are also network prerequisites to be met in order to guarantee good security of the architecture, which means that the product is only available to large customers. Besides, the license starts at 100TB. An Appliance version is being developed with an architecture based on containers which will make it possible to offer DataCore SWARM to everyone. The product has been evolving since the acquisition by DataCore, but maintaining and updating the product is not always easy and needs to be improved. For now, we only use DataCore SWARM for a few use cases and therefore a small part of the existing functionalities. With use we will perhaps have more criticism of the product but not for the moment!"

"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 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."

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

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

"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."

"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

"Our customers have seen a reduction in TCO."

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

"The price could be cheaper."

"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."

"The product is very expensive."

"I understand that it is competitively priced compared to other brands."

"We used a reseller for the purchase."

"The price of this solution could be made more affordable."

More Pure Storage FlashBlade pricing and cost advice

"You pay for what you use. For example, if you use one terabyte, you just pay for that one terabyte. But the pricing could always be better"

"The first installation brick is expensive but the upgrades are extremely simple and granular by adding disks or nodes."

"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."
