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.

Flexibility and reliability have supported seamless data growth

I cannot think of anything to improve about Dell PowerScale (Isilon). The hardest challenge we have is due to how we've bought things over time. The way that we moved to the PowerEdge platform for the newer systems creates a scale problem as I still buy the older style systems, which are more dense storage. They're different chassis, so the problem we run into in the data center is the depth of the actual equipment. The newer equipment, if we buy an FX910 or a 900, it's a lot shorter in scale than if I buy an 83,000, which is much bigger. This makes it more complicated for deployment.

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.

"The most valuable feature for me is SyncIQ."

"The solution is stable."

More Dell PowerScale (Isilon) pros

"Ceph has simplified my storage integration, as I no longer need two or three storage systems since Ceph can support all my storage needs, replacing OpenStack Swift for REST object storage access, NFS or GlusterFS for filesystem sharing, and LVM or DRBD for virtual machines in OpenStack."

Cons

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

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

"The speed could be improved."

"The integration with S3 needs some improvement."

"The Pure Storage Orchestrator is our biggest pain point at the moment."

"Its configuration should be easier."

More Everpure FlashBlade cons

"The legacy file system for Epsilon didn't scale into the cloud and didn't have a separate OS."

"Some improvements to the NFS support would be of interest to us."

"Technical support could be improved. Whenever we have a hiccup, we'd like to get it fixed maybe quicker."

"Pricing is an issue. It's quite expensive for the amount of storage we have."

"I would like to see increased reporting and statistics functionalities."

"We had some issues with level 1 support. We had to fight with them on repeated issues. There is room for improvement in level 1 support."

"The hardest challenge we have is due to how we've bought things over time. The way that we moved to the PowerEdge platform for the newer systems creates a scale problem as I still buy the older style systems, which are more dense storage."

"It needs a better UI for easier installation and management."

"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."

"Please create a failback solution for OpenStack replication and maybe QoS to allow guaranteed IOPS."

"We have encountered slight integration issues."

"Ceph does not deal very well with, or takes a long time to recover from, certain kinds of network failures and individual storage node failures."

Pricing and Cost Advice

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

"We used a reseller for the purchase."

"Our licensing is renewed annually."

"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."

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

"Licensing fees are paid yearly."

"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."

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

More Everpure FlashBlade pricing and cost advice

"Price was also a significant factor in our decision to go with PowerScale. The team at EMC, now Dell EMC, came through with a highly competitive offer that tipped the scales towards their solution. There was only one other solution around the same price point, but it could not match PowerScale on features. That other solution is no longer on the market."

"The pricing is expensive, but I think it's a fair value because it does manage itself. It definitely is much simpler than any of the other scale-out storage platforms that we've looked at in the past."

"I always want things to be less expensive. However, I would say the pricing is fair. Their costs are in alignment with their competitors. It is a good value for the money."

"The platform is not cheap. However, on the software side, you can choose what you want license. So, you can start your licensing with the features that you need, then after buying the platform add some other features."

"The solution's licensing cost varies based on capacity and performance requirements."

"Pricing for this solution is reasonable."

"The general cost for a system like this is expensive. The total cost depends on your use case. You need to pay for every additional feature that you use."

"The solution is expensive; it is not the cheapest solution out there. If you look at it from a total cost of ownership perspective, then it is a very compelling solution. However, if you're looking at just dollar per terabyte and not looking at the big picture, then you could be distracted by the price. It is not an amazing price, but it's pretty good. It is also very good when you consider the total cost of ownership and ease of management."

More Dell PowerScale (Isilon) pricing and cost advice

"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."

"The other big advantage is that Ceph is free software. Compared to traditional SAN based storage, it is very economical."

"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 price of Red Hat Ceph Storage is reasonable."

"There is no cost for software."

"We never used the paid support."
