Parul-Patel

Senior Network Engineer at Holy Redeemer Health System, Inc.

High performance and throughput enhance IT backup management

The multi-dimensional scale-out design feature of Pure Storage FlashBlade is not in use in our environment. Regarding data reduction technologies, we don't get much deduplication because the data is already deduplicated from our FlashArray before we get to backup, so there is no benefit of deduplication. Regarding the integration with cloud-native ecosystem tools, we are not on cloud; we are strictly an on-premises solution. Pure Storage FlashBlade is not used by any end-user; it's used only for IT backup, with only about four people in our group managing it. I cannot recommend Pure Storage FlashBlade to other users depending upon their financial situation because it's an expensive solution, and the cost is very high, including licensing and renewal every year. I rate Pure Storage FlashBlade an eight out of ten.

Senior Infrastructure Specialist at a healthcare company with 10,001+ employees

Manages large data sets efficiently with hybrid cloud integration

My organization is quite large, with about 30,000 employees. The growth has been substantial in areas such as radiology and genomics. One of the best features we've utilized recently is offload to cloud pools due to capacity constraints on-premise. We didn't want to expand Dell PowerScale (Isilon) straight away, so we utilized cloud pools to offload some data to Azure. That's really saved us in certain areas as we didn't have funding to expand Dell PowerScale (Isilon) until next year, which is why we utilized the cloud pools functionality to offload.

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 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."

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

"The onboarding and integrated monitoring tools are pretty good."

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

"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."

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

"Speed and ease of use are the two most 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."

More Pure Storage FlashBlade pros

"The solution's most valuable features are scalability and flexibility."

"My experience with Dell as a vendor is pretty good; they are probably one of the best in the industry."

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

"Dell PowerScale helps in saving costs related to power and rack space, reducing physical hardware from over one hundred to twenty-nine chassis."

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

"Its scalability has been huge for us."

"Dell PowerScale's performance is good."

"The tool comes with cheap disks and works fast for video content."

More Dell PowerScale (Isilon) pros

"Most valuable features include replication and compression."

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

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

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

"radosgw and librados provide a simple integration with clone, snapshots, and other functions that aid in data integrity."

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

"We have some legacy servers that can be associated with this structure. With Ceph, we can rearrange these machines and reuse our investment."

More Red Hat Ceph Storage pros

Cons

"Pure Storage FlashBlade should improve on more cloud integration."

"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."

"There could be improvements in public cloud integration."

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."

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

"I would like to see more VM-Aware features in the next release of this solution."

"I want efficiency. FlashBlade doesn't have efficiency now."

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

More Pure Storage FlashBlade cons

"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."

"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."

"Dell PowerScale (Isilon) is a bit expensive compared to other products."

"It is a bit higher priced than some of the other systems."

"The only thing that I think PowerScale could do better is improving the HTTP data access protocol. At the present, you cannot protect access to data via HTTP or HTTPS the same way that you can secure data access through other protocols like NFS or SMB[...]the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply."

"We lost our technical sales reps about two years ago. We haven't gotten one assigned to us and we'd love to have one."

"The management and monitoring tools comprise a disparate suite of products and the roadmap is very unclear. We've got four different products that look after the Isilon, management-wise, and it's a bit of a mess."

"The cost of Dell PowerScale is currently high and there is room for improvement."

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."

"The management features are pretty good, but they still have room for improvement."

"In the deployment step, we need to create some config files to add Ceph functions in OpenStack modules (Nova, Cinder, Glance). It would be useful to have a tool that validates the format of the data in those files, before generating a deploy with failures."

"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."

"The licensing cost is excessively high. This is a significant issue from my perspective."

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

"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."

More Red Hat Ceph Storage cons

Pricing and Cost Advice

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

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

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

"We used a reseller for the purchase."

"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 feel that the price could always be lowered."

"Our customers have seen a reduction in TCO."

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

More Pure Storage FlashBlade pricing and cost advice

"The pricing is excellent."

"The pricing for this solution is reasonable."

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

"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."

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

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

"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."

"Pricing for this solution is reasonable."

More Dell PowerScale (Isilon) pricing and cost advice

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

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

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

"There is no cost for software."

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

"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."

"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."
