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 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 solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."

"The product is scalable and easy to expand."

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

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

"The tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."

More Everpure FlashBlade pros

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

"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."

"My experience when deploying Dell PowerScale (Isilon) was very straightforward, as we had Dell come on site to do all the actual setup, which was a big help."

"The most valuable feature of the solution is its performance."

"I rate Dell PowerScale (Isilon) a ten out of ten, and we continue to keep buying it."

"Ability to scale the number of nodes without having to build additional clusters."

"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."

"Isilon is flexible in supporting various data workloads while keeping them protected. Dell continues to release updates and patches which enhance the use of this solution. This includes offering ransomware protection."

More Dell PowerScale (Isilon) pros

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

"The setup is very easy, deserving a ten out of ten."

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

"Ceph Storage allows us to add value related to cost and offers a unique experience compared to traditional storage."

"It has helped to save money and scale the storage without limits."

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

"The most valuable feature is the stability of the product."

"Data redundancy is a key feature, since it can survive failures (disks/servers). We didn’t lose our data or have a service interruption during server/disk failures."

More Red Hat Ceph Storage pros

Cons

"The speed could be improved."

"The documentational aspect of FlashBlade needs improvement."

"Commvault has mainly driven the Analytics, providing data and reports. However, the product has room for improvement, especially regarding storage analytics. Upgrading firmware has caused issues, requiring feature disabling to revert to traditional backups. The firmware upgrades sometimes affect Commvault backups."

"I would also like to see better support for CIFS workloads."

"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."

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

"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

More Everpure FlashBlade cons

"Always, there is room for improvement in terms of cybersecurity, as new challenges are continually emerging in the market."

"Some improvements to the NFS support would be of interest to us."

"PowerScale is not suitable for virtual environments."

"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."

"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."

"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."

"Data storage performance needs to be improved."

"Dell PowerScale's deployment is not easy."

More Dell PowerScale (Isilon) cons

"Some documentation is very hard to find."

"When it comes to the capabilities of Red Hat Ceph Storage such as object, block, and file storage, I am not fully satisfied."

"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."

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

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

"I would like to see better performance and stability when Ceph is in recovery."

"While the documentation for Ceph Storage is helpful, it could be improved."

"It would be nice to have a notification feature whenever an important action is completed."

More Red Hat Ceph Storage cons

Pricing and Cost Advice

"The price could be cheaper."

"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."

"We used a reseller for the purchase."

"Our customers have seen a reduction in TCO."

"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."

"Licensing fees are paid yearly."

"The price is a little high."

More Everpure FlashBlade pricing and cost advice

"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."

"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."

"It is an expensive solution."

"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."

"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."

"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."

"The platform is not cheap. However, on the software side, you can choose what you want license. So, you can start your licensing with the features that you need, then after buying the platform add some other features."

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."

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

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

"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."

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

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

"There is no cost for software."
