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

"The most valuable features of this solution are the rewrite speed and the nonstop services."

"The most valuable features are the Metro clustering, and disaster recovery."

"The most valuable feature is Safe Mode."

"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."

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

"The initial setup is pretty easy and simple."

"The initial setup is pretty quick."

"The most valuable feature of this solution is performance."

More Everpure FlashBlade pros

"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."

"Customer service has been really good."

"Our main goal is to do disaster recovery with whatever solution we use and Isilon makes it pretty simple to replicate those workloads over to our secondary data center."

"Dell PowerScale's performance is good."

"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."

"PowerScale helped free up our employees' time to focus on other business priorities. There are now automated jobs such as backing up and replicating data, that reduce the footprint we have. Those types of tasks were previously done manually."

More Dell PowerScale (Isilon) pros

"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. The solution continues working even when there are errors."

"I would definitely recommend Red Hat Ceph Storage. It is a complete solution for cloud-native storage needs."

"We are using Ceph internal inexpensive disk and data redundancy without spending extra money on external storage."

"The ability to provide block storage and object storage from the same storage cluster is very valuable for us."

"It's a very performance-intensive, brilliant storage system, and I always recommend it to customers based on its benefits, performance, and scalability."

"The configuration of the solution and the user interface are both quite good."

"I like the distributed and self-healing nature of the product."

"Most valuable features include replication and compression."

More Red Hat Ceph Storage pros

Cons

"I would like to see the licensing fees improved as well as the price per terabytes."

"There could be improvements in public cloud integration."

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

"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."

"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."

"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."

"It's on the expensive side, as expected for a niche product."

"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."

More Everpure FlashBlade cons

"I have experienced a RAM failure in some of the nodes of Dell PowerScale (Isilon), and that required hardware replacement."

"Its configuration needs to be more straightforward."

"The price always has room for improvement."

"There are some missing features in the product, especially when our company needs to do some tape backup, and we see that the tool doesn't have integration capabilities."

"That said, for the other security features, it would be helpful if Tenable - and I know it's outside the scope of this question itself - had Isilon-specific plugins."

"Isilon has limitations on the number of files that can be generated."

"Backward compatibility is something Dell PowerScale (Isilon) could work on."

"If they integrated some functions, as they have on Data Domain with a cyber recovery vault, it would be ideal."

More Dell PowerScale (Isilon) cons

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

"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."

"If you use for any other solution like other Kubernetes solutions, it's not very suitable."

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

"Some documentation is very hard to find."

"An area for improvement would be that it's pretty difficult to manage synchronous replication over multiple regions."

"Ceph is not a mature product at this time. Guides are misleading and incomplete. You will meet all kind of bugs and errors trying to install the system for the first time. It requires very experienced personnel to support and keep the system in working condition, and install all necessary packets."

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

More Red Hat Ceph Storage cons

Pricing and Cost Advice

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

"Our customers have seen a reduction in TCO."

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

"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."

"The price is a little high."

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

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

"Licensing fees are paid yearly."

More Everpure FlashBlade pricing and cost advice

"Dell PowerScale is an expensive solution compared to other products like Qumulo."

"Our company finds the pricing high, but it decreases over time."

"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."

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

"The pricing is excellent."

"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."

"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."

"It is an expensive solution."

More Dell PowerScale (Isilon) pricing and cost advice

"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."

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

"We never used the paid support."

"There is no cost for software."

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

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

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

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