MikaelHellström

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.

Bill Engelmeyer

Systems Engineer at Unisity LLC

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.

Rifat Rahman

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

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."

"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."

"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."

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

"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."

"The tool's most valuable feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."

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

"Pure Storage FlashBlade's scalability is one of the most valuable features, and importantly, it always works, allowing for seamless upgrades."

More Pure Storage FlashBlade pros

"PowerScale allows us to manage storage without managing RAID groups or migrating volumes between controllers. It has really simplified things. We're not having to worry about the underlying infrastructure. That takes care of itself. We just worry about the data. It's really easy for deploying and managing storage at the petabyte scale."

"Dell PowerScale (Isilon) definitely deserves ten out of ten for scalability."

"It's easy to manage. The web UI is very intuitive, and there's CLI also that you can use to manage it."

"The features of Dell PowerScale (Isilon) that I appreciate the most include the scale of architecture and the way it is designed, which benefit my company by providing less downtime and less overhead."

"The guaranteed performance, combined with the scalability through its scale-out capability, makes it an excellent choice."

"This is the best platform that we could have for storage utilization. It is affordable and scalable. At the end of the day, it's something that we find very easy to use."

"We use the solution internally to support our own managed servers and run our own support center."

"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."

More Dell PowerScale (Isilon) pros

"The high availability of the solution is important to us."

"The community support is very good."

"Without any extra costs, I was able to provide a redundant environment."

"Ceph was chosen to maintain exact performance and capacity characteristics for customer cloud."

"It has helped to save money and scale the storage without limits."

"The solution is pretty stable."

More Red Hat Ceph Storage pros

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."

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

"It would be nice if you could store file-based in the same box with the same technology."

"I would like to see better integration."

"Its configuration should be easier."

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

"Its configuration should be easier."

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

More Pure Storage FlashBlade cons

"The legacy file system for Epsilon didn't scale into the cloud and didn't have a separate OS. It would be key if this was made possible."

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

"The support offered by the product is an area of concern where improvements are required."

"There aren't many templates still coming out for it. They need to provide templates so we can copy and paste what we've done in the past to future, new things."

"Dell PowerScale (Isilon) could improve in terms of having some problems with using IPv6 and IPv4 on the same namespace at the same time, which is one of our biggest problems as you have to do some really bad workarounds to get that working."

"Dell's customer service needs improvement."

"They could improve implementation, as we had to rack and stack it ourselves."

"Because of the magic that it does 'under the hood,' it is very difficult to find out within the system where all your storage is going. That's a little bit of a ding that we have on it. It does so much magic in order to protect itself from drive failures or multiple drive failures, that it automatically handles the provisioning and storage of your data. But by doing that, finding out why a file of a certain size, or a directory of a certain size, is using more storage than is being reported in InsightIQ, is very difficult to discern."

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."

"Some documentation is very hard to find."

"Geo-replication needs improvement. It is a new feature, and not well supported yet."

"Routing around slow hardware."

"While the documentation for Ceph Storage is helpful, it could be improved."

"I would like to see better performance and stability when Ceph is in recovery."

"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."

"The storage capacity of the solution can be improved."

More Red Hat Ceph Storage cons

Pricing and Cost Advice

"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 price is a little high."

"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 could be cheaper."

"I understand that it is competitively priced compared to other brands."

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

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

"The product is very expensive."

More Pure Storage FlashBlade pricing and cost advice

"The pricing is excellent."

"The price of the solution is high."

"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."

"It's a high-cost offering amounting to three or four million Swedish kronor, or about $400,000 or euros, for approximately 480 terabytes of storage."

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

"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."

"Dell PowerScale (Isilon) is an expensive solution."

"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."

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."

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

"We never used the paid support."
