Featured Reviews

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.

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 - 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.

"It performs well and it is also very fast."
"From the customer's perspective, this is the easiest product that I've tested, it's seamless."
"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 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."
"Of all the components in our IT system, it's probably the least troublesome."
"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."
"Dell PowerScale (Isilon) is a platform that is very easy for teams to work with."
"It is stable and very user-friendly."
"This has been a valuable solution for our business overall. It offers business continuity and replication features."
"On a scale of one to ten, with one being worst and ten being best, I would rate Dell PowerScale (Isilon) a ten."
"The solution is extremely easy to manage. This is its most valuable feature."
"Ceph Storage allows us to add value related to cost and offers a unique experience compared to traditional storage."
"Ceph’s ability to adapt to varying types of commodity hardware affords us substantial flexibility and future-proofing."
"Companies that can afford completely flash-based pipe servers should go for Ceph because it's a very performance-intensive, brilliant storage system, and I always recommend it to customers based on its benefits, performance, and scalability."
"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."
"Stratus allows more reliability than all the other types of computers available."
"Ceph was chosen to maintain exact performance and capacity characteristics for customer cloud."
"The most valuable feature is the stability of the product."

Cons

"I would like to see more deduplication."
"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."
"I would like to see more monitoring capability included in the next release of this solution."
"I would like to see better integration."
"The speed could be improved."
"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 technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."
"I want efficiency. FlashBlade doesn't have efficiency now."
"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."
"I would want to see more AI features with Dell PowerScale (Isilon)."
"Dell PowerScale (Isilon) is a little bit pricey, and its pricing could be improved."
"My experience with customer service and technical support has been challenging. The reason is that it is difficult to find subject matter experts around the solution."
"The biggest weakness is small file handling. Small file compression options are not enabled out of the box. It would be good to have this enabled by default."
"Backward compatibility is something Dell PowerScale (Isilon) could work on."
"I have experienced a RAM failure in some of the nodes of Dell PowerScale (Isilon), and that required hardware replacement."
"The initial setup for this solution is complex."
"We have encountered slight integration issues."
"I have not identified any drawbacks, however, the response to public platform inquiries could be faster."
"The product lacks RDMA support for inter-OSD communication."
"The storage capacity of the solution can be improved."
"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."
"When it comes to the capabilities of Red Hat Ceph Storage such as object, block, and file storage, I am not fully satisfied."
"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."
 

Pricing and Cost Advice

"The price could be cheaper."
"I rate the tool's pricing a seven to eight out of ten."
"The price is a little high."
"I feel that the price could always be lowered."
"Our licensing is renewed annually."
"The product is very expensive."
"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."
"The pricing for FlashBlade is between cheap and moderate."
"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."
"It is a really expensive solution."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"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."
"Our company finds the pricing high, but it decreases over time."
"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."
"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 is expensive on the start-up side but we can recoup those costs quickly by not having to reapply the savings to other equipment."
"I rate the product’s pricing an eight out of ten."
"We never used the paid support."
"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 other big advantage is that Ceph is free software. Compared to traditional SAN based storage, it is very economical."
"The price of Red Hat Ceph Storage is reasonable."
"Most of time, you can get Ceph with the OpenStack solution in a subscription​​ as a bundle.​"
"The price of this product isn't high."
