Eric Burgueño - PeerSpot reviewer
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.
ANDRE VINICIUS HAMERSKI - PeerSpot reviewer
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

"There are also the policies that you set up on replication and purging files, and policies for something called WORM. That's a "write once, read many," where you can't overwrite certain files or certain data. It puts them in a "protected mode" where it becomes very difficult for someone to accidentally delete. We use that for certain files or certain directories, because we're dealing with video and some video has to be protected for chain-of-custody purposes. The WORM feature works great."
"The most valuable feature of Dell PowerScale is its scalability."
"Its scalability has been huge for us."
"It is stable and very user-friendly."
"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."
"The tool's most valuable features are high density and scalability."
"For maximizing storage utilization, PowerScale is great. When you write the data to it, it spreads it out to all the nodes, so you get all the performance from the entire pool."
"The best thing is that it works. We don't have to maintain it too much; we usually upgrade once a year."
"The community support is very good."
"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."
"Ceph Storage allows us to add value related to cost and offers a unique experience compared to traditional storage."
"Most valuable features include replication and compression."
"The ability to provide block storage and object storage from the same storage cluster is very valuable for us."
"I really like that Red Hat Ceph Storage can be used as a total solution without any storage area network components."
"We have not encountered any stability issues for the product."
"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."
 

Cons

"Dell PowerScale (Isilon) is a little bit pricey, and its pricing could be improved."
"Data storage performance needs to be improved."
"The solution's rate structure or rate redundancy needs to be improved."
"The improvement should be in AI. Everything is going towards AI."
"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."
"Always, there is room for improvement in terms of cybersecurity, as new challenges are continually emerging in the market."
"Dell PowerScale needs to reduce its price."
"There is room for improvement in its handling of object storage."
"What could be improved in Red Hat Ceph Storage is its user interface or GUI."
"Geo-replication needs improvement. It is a new feature, and not well supported yet."
"Routing around slow hardware."
"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."
"Some documentation is very hard to find."
"I have not identified any drawbacks, however, the response to public platform inquiries could be faster."
"I've heard the integration with OpenShift is great, however, the licensing cost is excessively high."
"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."
 

Pricing and Cost Advice

"It is an expensive solution."
"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'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."
"Dell PowerScale (Isilon) is an expensive solution."
"The pricing for this solution is reasonable."
"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 solution's licensing cost varies based on capacity and performance requirements."
"The price of the solution is high."
"The other big advantage is that Ceph is free software. Compared to traditional SAN based storage, it is very economical."
"The price of this product isn't high."
"I rate the product’s pricing an eight out of ten."
"The operational overhead is higher compared to Azure because we own the hardware."
"Most of time, you can get Ceph with the OpenStack solution in a subscription​​ as a bundle.​"
"We never used the paid support."
"The price of Red Hat Ceph Storage is reasonable."
"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."
