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.

More Red Hat Ceph Storage pros

Cons

"The documentational aspect of FlashBlade needs improvement."

"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."

"The features provided for SMB customers are limited."

"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."

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

"We have one system at a customer's site that has had a lot of problems over the last year — I think maintenance was required over seven times before everything was corrected."

"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."

"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."

More Everpure FlashBlade cons

"Perhaps if there was a local chatbot built within the system or on the dashboard where we could directly ask for anything on the OneFS, it could help us."

"We used to have a chat feature available on the support site. It's not available to us anymore."

"Dell's customer service needs improvement."

"There is room for improvement in its handling of object storage."

"Dell PowerScale (Isilon) is a little bit pricey, and its pricing could be improved."

"We're struggling with the UID mapping and how to configure mapping-related things."

"Since our Dell PowerScale (Isilon) is our own on-prem in-house built system, we don't have many up-to-date resources, and we're still a few years behind."

"We see room for improvement in Dell PowerScale (Isilon) because we need personnel to effectively utilize all our infrastructure; it's not easy to find skilled people to work on AI and data analysis."

More Dell PowerScale (Isilon) cons

"This product uses a lot of CPU and network bandwidth. It needs some deduplication features and to use delta for rebalancing."

"What could be improved in Red Hat Ceph Storage is its user interface or GUI."

"It takes some time to re-balance the storage in case of server failure."

"When it comes to the capabilities of Red Hat Ceph Storage such as object, block, and file storage, I am not fully satisfied."

"If troubleshooting is needed, the response should be faster."

"It took me a long time to get the storage drivers for the communication with Kubernetes up and running. The documentation could improve, it is lacking information."

"What could be improved in Red Hat Ceph Storage is its user interface or GUI."

"Ceph is not a mature product at this time. Guides are misleading and incomplete."

Pricing and Cost Advice

"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."

"I feel that the price could always be lowered."

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

"The price is a little high."

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

"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."

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

More Everpure FlashBlade pricing and cost advice

"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."

"This solution is priced slightly higher than others on the market but does offer good quality. With this solution's data reduction and compression, we were able to purchase less. Costs have dropped because of the data rate of compression and deduplication."

"The pricing for this solution is reasonable."

"The price of Dell PowerScale (Isilon) is reasonable."

"The price of the solution is high."

"We paid an additional fee to have Dell's ProDeploy Plus team implement it."

"We use the TNA approach which is a great opportunity for us to better manage the licenses based on how much consumption is available for the different customers so we can use that approach and scalability."

More Dell PowerScale (Isilon) pricing and cost advice

"Most of time, you can get Ceph with the OpenStack solution in a subscription as a bundle."

"I rate the product’s pricing an eight out of ten."

"We never used the paid support."

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

"The price of this product isn't high."

"The price of Red Hat Ceph Storage is reasonable."

"The operational overhead is higher compared to Azure because we own the hardware."

"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."
