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.

OpEx storage model has simplified SLAs, capacity planning, and cyber‑resilient recovery

The most valuable features in Pure Storage Evergreen One are the SLAs, which are tied to the kind of services that we are going to run. These SLAs govern the consumption and the reporting as well. I find it more attractive when we are tied to a specific SLA, and the VRA is providing the services within that agreed SLA, then there is no requirement for a complete capacity assessment. The entire capacity review, assessment, and recommendations come as part of Pure Storage Evergreen One solution. Pure Storage Evergreen One has a list of services which will provide the services, including cyber resilience. First, they have complete capacity management which is done by them and which will also provide us a heads up on how we are consuming the services and where these services can be improved. Second, it will also provide us some of the key attributes, such as we can take the snapshots and LUN snapshots, which will provide a cyber-resilient copy where data can be secured in case of a cyber attack. We have an option to basically recover the earliest. Third, because of this feature and because of Pure Storage Evergreen One, I am talking about the Evergreen aspect. Because of Evergreen, we also have an option to upgrade the controllers based on the SLAs. If the agreed SLAs are not meeting the requirement, we have a provision to upgrade the controllers and so on. This is giving a good feature for us to evaluate and provide a valuable proposition to the customer who wants to use Pure Storage as a Pure OpEx model.

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

"It uses the same platform for connectivity so integration is seamless."

"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."

"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."

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

"The performance of FlashBlade is excellent. It does not necessarily leverage the SOS API that some of the newer products leverage, but I found its speed pretty much on par and comparable. It is fast, and it does what it is supposed to do."

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."

"The initial setup is pretty quick."

"The most valuable feature of this solution is performance."

More Pure Storage FlashBlade pros

"Pure Storage has the highest Net Promoter Score in the market."

"The Evergreen program is excellent, and the pricing is quite reasonable. My friends who work there are doing very well and consistently achieving strong results. Like any company, they experience occasional downturns but perform impressively overall."

"The most valuable features in Pure Storage Evergreen One are the SLAs, which are tied to the kind of services that we are going to run, and these SLAs govern the consumption and the reporting as well."

"The speed of the product is quite a bit better in performance than the previous peer environment we were running on, and it seems to have a better feature set."

"The speed of the product is quite a bit better in performance than the previous environment we were running on, and it seems to have a better feature set."

"We have snapshots. We put snapshots on disks, and we can save information. In the case of ransomware, everything is in the snapshot. We have a snapshot lock on it, so it's safe."

"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."

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

"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."

"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."

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

"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."

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

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

More QoreStor pros

Cons

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

"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."

"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."

"Commvault has mainly driven the Analytics, providing data and reports. However, the product has room for improvement, especially regarding storage analytics. Upgrading firmware has caused issues, requiring feature disabling to revert to traditional backups. The firmware upgrades sometimes affect Commvault backups."

"It would be nice if you could store file-based in the same box with the same technology."

"The features provided for SMB customers are limited."

"Its configuration should be easier."

"Pure Storage FlashBlade should improve on more cloud integration."

More Pure Storage FlashBlade cons

"Many customers report that the starting price is quite high. However, the overall total cost of ownership can be reduced over time due to features like the Evergreen architecture, which allows savings through less management and environmental benefits."

"I'm not sure if any improvements are needed."

"To me, I think it's a little expensive. Then again, you get what you pay for."

"It would be nice to have support in Swedish."

"I would love to explore more options on what Pure Storage Evergreen One can offer in general, mostly from the cybersecurity perspective and air gap."

"The only potential drawback is that Pure Storage might be overkill if you don't need microsecond response times."

"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."

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

"The ransomware protection of QoreStor could use improvement."

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

"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."

"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."

"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."

Pricing and Cost Advice

"Our licensing is renewed annually."

"The price could be cheaper."

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

"We used a reseller for the purchase."

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

"The pricing for FlashBlade is between cheap and moderate."

"The price is a little high."

"The product is very expensive."

More Pure Storage FlashBlade pricing and cost advice

"The pricing is very good."

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

"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."

"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."
