The ability to leverage multi-tenancy along with immutability is a huge benefit for us

The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top. Veeam Backup specifically has started to streamline their API, and they are doing that with SOS API. They have optimized it. Any of the S3 devices out there that support this SOS API can have far more API calls at once. On our side, that translates to better restoration. With SOS API, it can leverage far more restorations at a single given time or read from the device in simple terms. That results in maximizing the output and throughput from the device itself.

Simplified data management, tremendously reducing our users’ cognitive overhead

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. You can either access a file because it can be access by anyone in the organization, or you cannot at all. There is no in-between. HTTP is not considered a first-class data access protocol, so the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply. However, with the recent introduction of S3 starting from OneFS 9, I believe the necessary plumbing is already there for HTTPS to also be elevated to a first-class protocol in the future because both protocols sit behind a web server under the hood. It does not sound like it would be too complicated to implement, but it would be a valuable feature and it is currently missing.

Offers cost-effective scalability through open-source storage integration

Ceph Storage allows us to add value related to cost and offers a unique experience compared to traditional storage. We appreciate the scalability of the open-source solution, allowing us to address our growing data needs without encountering major issues. Having used it as a pilot system in Brazil, we gained significant knowledge and the ability to manage our infrastructure as code.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"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."

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

"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."

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

"The solution provides many controllers."

"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."

"It's very easy-to-use."

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

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."

"The solution has simplified management by consolidating our workloads. Rather than managing all the different workloads on different storage arrays, Windows Servers, etc., we just have one place per data centre where we manage all their unstructured data, saving us time."

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

"The most valuable feature of Dell PowerScale (Isilon) is all the capabilities together."

"Dell PowerScale has the SmartConnect and SmartConnect Pro features. That's why I like the product."

"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."

"The stability of the solution is good."

"The fact that we were able to set it up, use it, and, for the most part, didn't have to worry about it after we had it set up has been valuable."

More Dell PowerScale (Isilon) pros

"What I found most valuable from Red Hat Ceph Storage is integration because if you are talking about a solution that consists purely of Red Hat products, this is where integration benefits come in. In particular, Red Hat Ceph Storage becomes a single solution for managing the entire environment in terms of the container or the infrastructure, or the worker nodes because it all comes from a single plug."

"The solution is pretty stable."

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

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

"We have not encountered any stability issues for the product."

"High reliability with commodity hardware."

"The community support is very good."

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

More Red Hat Ceph Storage pros

Cons

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

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

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."

"I would like to see more deduplication."

"The features provided for SMB customers are limited."

"The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top."

"They need better integration with public clouds along with a better hybrid solution."

"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."

More Pure Storage FlashBlade cons

"The solution's rate structure or rate redundancy needs to be improved."

"Improvements could be made to reduce the costs and the high level of knowledge needed to maintain and use them. We had old hard drives with moving parts in Dell PowerScale, and due to this, we must switch to a more efficient environment with all-flash."

"The solution can be integrated with an automation system. Dell uses another framework developed in-house. They can integrate it with machines."

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

"The UID mapping and how to configure mapping-related things is a struggle."

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

"There is room for improvement with the updates. It can take a significant amount of time to do a major OS update. However, even though it takes multiple reboots, the cluster stays up. If we want to apply a newer version of the OS, we have to roll back some of the patches so that we can upgrade. It requires a few reboots just to do that. The cluster doesn't come down, everything is still running, but it's time-consuming, at times."

"The pricing could be reduced."

More Dell PowerScale (Isilon) cons

"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."

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

"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. I'm not sure if this is a Ceph problem or if Ceph should address this, but it was something I ran into. Additionally, there is a performance issue I am having that I am looking into, but overall I am satisfied with the performance."

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

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

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

"I have not identified any drawbacks, however, the response to public platform inquiries could be faster."

"Routing around slow hardware."

Pricing and Cost Advice

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

"Our customers have seen a reduction in TCO."

"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."

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

"The product is very expensive."

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

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

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

More Pure Storage FlashBlade pricing and cost advice

"It is an expensive product with a high storage capacity suitable for large data requirements."

"It is an expensive solution."

"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."

"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."

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

"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."

"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."

"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."

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."

"We never used the paid support."

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

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

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

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

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

"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."

Reviews from Real Users

Dell EMC PowerScale storage stands out among its competitors for a number of reasons. Two major ones are its scalability capabilities and its user-friendly centralized management system.

Rachel B., a chief operations officer & acting CFO at Like a Photon, writes, "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."

Keith B., the director of IT at NatureFresh Farms, writes, "The single pane of glass for both IT and for the end-user is a valuable feature. On the IT side, I can actually control where things are stored, whether something is stored on solid-state drives or spinning drives... The single pane of glass makes it very easy to use and very easy to understand. We started at 100 terabytes, and we moved to 250 and it still feels like the exact same system and we're able to move data as needed."
