MikaelHellström - PeerSpot reviewer
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.

Backup storage has shrunk dramatically with deduplication but still needs stronger security options
The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.
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 number one aspect of FlashBlade is performance; the ability to move large amounts of data through a training array is pretty much unparalleled, and the scalability has been great."
"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."
"If you need high throughput the FlashBlade is the best solution for you."
"The tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."
"The most valuable features of this solution are the rewrite speed and the nonstop services."
"Its SSD to storage is its most valuable feature. It helps simplify our storage, because the user interface is very simple and the installation is easy."
"This solution has improved how our organization functions in the way that it has essentially made us not have to think about storage."
"The fact that the solution is extremely stable and it works really great each dollar spent on this solution is worth it."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"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."
"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."
"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."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"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."
"The setup is very easy, deserving a ten out of ten."
"Ceph’s ability to adapt to varying types of commodity hardware affords us substantial flexibility and future-proofing."
"Ceph was chosen to maintain exact performance and capacity characteristics for customer cloud."
"Replicated and erasure coded pools have allowed for multiple copies to be kept, easy scale-out of additional nodes, and easy replacement of failed hard drives, and the solution continues working even when there are errors."
"The ability to provide block storage and object storage from the same storage cluster is very valuable for us."
"Most of the features are beneficial and one does not stand out above the rest."
"I like the distributed and self-healing nature of the product."
"Stratus allows more reliability than all the other types of computers available."
 

Cons

"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 want efficiency. FlashBlade doesn't have efficiency now."
"I would like to see the licensing fees improved as well as the price per terabytes."
"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."
"In my opinion, one way Pure Storage FlashBlade can be improved is by having more compatibility between the FlashArray and FlashBlade, allowing for synchronized data between both platforms."
"I would like to see better integration."
"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."
"They need better integration with public clouds along with a better hybrid solution."
"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."
"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."
"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 air gap feature is something I'd really like to see in QoreStor."
"The setup of the software is definitely not the easiest thing in the world."
"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."
"Areas of Red Hat Ceph Storage that have room for improvement include more promotion. Many people do not know about the Stratus case, which is one of the most reliable systems available in the world, but they are not aware that a system can keep working even if there is a hardware failure."
"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."
"We have encountered slight integration issues."
"I would like to see better performance and stability when Ceph is in recovery."
"Routing around slow hardware."
"While the documentation for Ceph Storage is helpful, it could be improved."
"Geo-replication needs improvement. It is a new feature, and not well supported yet."
 

Pricing and Cost Advice

"The price is a little high."
"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."
"We used a reseller for the purchase."
"Our licensing is renewed annually."
"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."
"I feel that the price could always be lowered."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"Licensing fees are paid yearly."
"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."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"The operational overhead is higher compared to Azure because we own the hardware."
"We never used the paid support."
"Most of time, you can get Ceph with the OpenStack solution in a subscription​​ as a bundle.​"
"There is no cost for software."
"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."
"The price of Red Hat Ceph Storage is reasonable."
"The price of this product isn't high."
"I rate the product’s pricing an eight out of ten."
