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.

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.
Rifat Rahman - PeerSpot reviewer
Infrastructure Architect & CEO at Tirzok Private Limited
Offers reliable performance and availability for large deployments
I would like to see improvements in Red Hat Ceph Storage not because I necessarily think it needs improvement, but because I generally prefer to do things manually rather than following the containerization part. Current deployments are based on containers, but I deploy manually with my scripts and controls. If there are no Kubernetes-like requirements, I often prefer to deploy a whole manual process. I don't ask for improvements in the deployment model because Red Hat has its own philosophy about making things, but it's my personal choice that I prefer things manually. Some features are available only in the containerization part, so if those are also available in manual deployment, that will help.

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 would rate Pure Storage FlashBlade a ten out of ten."
"The onboarding and integrated monitoring tools are pretty good."
"The most valuable feature is Safe Mode."
"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."
"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."
"It is very easy to use, and it is very fast."
"The main feature I have found to be product replication."
"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."
"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."
"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."
"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."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"I like the distributed and self-healing nature of the product."
"The solution is pretty stable."
"I really like that Red Hat Ceph Storage can be used as a total solution without any storage area network components."
"The most valuable feature is the stability of the product."
"Ceph Storage allows us to add value related to cost and offers a unique experience compared to traditional storage."
"What I found most valuable from Red Hat Ceph Storage is integration because if you are talking about a solution that consists purely of Red Hat products, this is where integration benefits come in. In particular, Red Hat Ceph Storage becomes a single solution for managing the entire environment in terms of the container or the infrastructure, or the worker nodes because it all comes from a single plug."
"We have not encountered any stability issues for the product."
"Ceph Storage allows us to add value related to cost and offers a unique experience compared to traditional storage."
 

Cons

"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 also like to see better support for CIFS workloads."
"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."
"The documentational aspect of FlashBlade needs improvement."
"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."
"The features provided for SMB customers are limited."
"I would like to see more monitoring capability included in the next release of this solution."
"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."
"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."
"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 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."
"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."
"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."
"Geo-replication needs improvement. It is a new feature, and not well supported yet."
"It needs a better UI for easier installation and management."
"I would like to see better performance and stability when Ceph is in recovery."
"In the deployment step, we need to create some config files to add Ceph functions in OpenStack modules (Nova, Cinder, Glance). It would be useful to have a tool that validates the format of the data in those files, before generating a deploy with failures."
"What could be improved in Red Hat Ceph Storage is its user interface or GUI."
"I have encountered issues with stability when replication factor was not 3, which is the default and recommended value. Go below 3 and problems will arise."
"This product uses a lot of CPU and network bandwidth. It needs some deduplication features and to use delta for rebalancing."
"Rebalancing and recovery are a bit slow."
 

Pricing and Cost Advice

"We used a reseller for the purchase."
"The price could be cheaper."
"Our customers have seen a reduction in TCO."
"The pricing for FlashBlade is between cheap and moderate."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"I understand that it is competitively priced compared to other brands."
"The price of this solution could be made more affordable."
"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."
"I rate the product’s pricing an eight out of ten."
"If you can afford a product like Red Hat Ceph Storage then go for it. If you cannot, then you need to test Ceph and get your hands dirty."
"We never used the paid support."
"Most of time, you can get Ceph with the OpenStack solution in a subscription​​ as a bundle.​"
"The operational overhead is higher compared to Azure because we own the hardware."
"The other big advantage is that Ceph is free software. Compared to traditional SAN based storage, it is very economical."
"There is no cost for software."
"The price of Red Hat Ceph Storage is reasonable."
