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.

Jeff Manuszak

CTO at EDSI

Cost-efficient, highly scalable, and installable on different types of hardware

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. We are pretty lenient as we do a lot of IT support ourselves. We are not very hard on support organizations, but when a customer has a support issue, it would be easier if the support processes were a little bit more automated. It would be beneficial to have an easier way to upload diagnostic dump files. They can make it easy for the customer to collect the diagnostic data. 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. This is especially critical because it stores customers' backups, and a failure can have significant business impacts. If a customer does not have the backups and has a disaster, they can be out of business, so monitoring is key.

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 FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

"The most valuable feature is Safe Mode."

"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."

"The onboarding and integrated monitoring tools are pretty good."

"We have seen a reduction in the total cost of ownership by around 20%."

"It helps simplify our storage, because the user interface is very simple and the installation is easy."

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

"I would rate Pure Storage FlashBlade a ten out of ten."

More Pure Storage FlashBlade pros

"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."

"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."

"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 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."

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

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

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

"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."

More QoreStor pros

"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."

"VMware Software Defined Storage gives higher availability against data corruption."

"The most valuable features of the solution are that it is easy to deploy and the support is really good."

"The single management panel is the main feature that is wonderful for the customer."

"This is an easy-to-use product for adding flexibility to your storage solution."

"The best part of the solution is that you can actually scale up to a large number of operating systems without additional hardware."

"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."

"The solution is simple to configure and provides good performance and less footprint."

Cons

"The feature that we're waiting on is better integration with the cell services."

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."

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

"The speed could be improved."

"Its configuration should be easier."

"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."

"I would like to see more monitoring capability included in the next release of this solution."

"There could be improvements in public cloud integration."

More Pure Storage FlashBlade cons

"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."

"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."

"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 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."

"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."

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

More QoreStor cons

"VMware Software Defined Storage should include a shared database on a standard version."

"Simplifying the licensing model and making it cheaper would improve the solution."

"It doesn't have the ability to be deployed on any kind of hardware and network connectors."

"The solution has some limitations in terms of replication to remote sites or cloud infrastructure, which need improvement."

"There is room for more integrations and plugins into more storages."

"The performance is not as good as some competing products and reporting can be improved."

"I'd like to see improved hardware compatibility"

"The license model of the product is an area of concern where improvements are required."

Pricing and Cost Advice

"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."

"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."

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

"I rate the tool's pricing a seven to eight out of ten."

"The product is very expensive."

"Licensing fees are paid yearly."

"We used a reseller for the purchase."

"The price could be cheaper."

More Pure Storage FlashBlade pricing and cost advice

"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."

"The product is quite expensive and is among the most expensive for this type of solution."

"A single socket costs you around US $6,000 for three years. At a minimum, you have a three load cluster for a medium or enterprise-scale company. It can get quite expensive because you're likely to need four to six sockets on the other side. It comes to around $30,000."

"I believe there is a yearly licensing fee of around $2000 - $5000. I don't think there are additional costs above that but it depends on the type of infrastructure you're booting."

"VMware Software Defined Storage is a slightly expensive solution."

"The solution is very expensive."
