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

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

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

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

"It performs well and it is also very fast."

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

"It is very easy to use, and it is very fast."

"The most valuable feature of this solution is performance."

"Pure Storage FlashBlade's scalability is one of the most valuable features, and importantly, it always works, allowing for seamless upgrades."

More Everpure FlashBlade pros

"Regarding stability, I find no lagging, crashing, or downtime with Dell PowerScale (Isilon), and it is a highly scalable, stable, and reliable solution that I have experienced."

"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."

"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."

"PowerScale helped free up our employees' time to focus on other business priorities. There are now automated jobs such as backing up and replicating data, that reduce the footprint we have. Those types of tasks were previously done manually."

"Dell PowerScale includes a wealth of features that are important from a security and recovery perspective."

"Dell PowerScale (Isilon) has powerful security, which makes it a very reliable storage solution for our content, and also the support and observability of our system; the call home feature is fantastic because when it presents an issue, Dell automatically opens a ticket regarding any warnings or alerts, allowing us to have a complete view of our system's health."

"Eyeglass is used to monitor for malware, which is very useful for us."

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

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

"Red Hat Ceph Storage is a reliable solution, it works well."

"I can compare Red Hat Ceph Storage with products from other vendors; I explored quite a few, but I still find that Red Hat Ceph Storage is making the most disruption."

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

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

"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

"I would like to see more monitoring capability included in the next release of this solution."

"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."

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

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

"The documentational aspect of FlashBlade needs improvement."

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

More Everpure FlashBlade cons

"We see room for improvement in Dell PowerScale (Isilon) because we need personnel to effectively utilize all our infrastructure; it's not easy to find skilled people to work on AI and data analysis."

"There is room for improvement in its handling of object storage."

"Pricing is an issue. It's quite expensive for the amount of storage we have."

"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."

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

"Improvements could be made to reduce the costs and the high level of knowledge needed to maintain and use them."

"I would like to see Dell PowerScale (Isilon) improved by enhancing the user interface, OneFS, to make advanced conversation and troubleshooting more specific, upgrade and batch management, providing deeper built-in analytics for performance and capacity planning."

"Perhaps if there was a local chatbot built within the system or on the dashboard where we could directly ask for anything on the OneFS, it could help us."

More Dell PowerScale (Isilon) cons

"Ceph does not deal very well with, or takes a long time to recover from, certain kinds of network failures and individual storage node failures."

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

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

"This product uses a lot of CPU and network bandwidth. It needs some deduplication features and to use delta for rebalancing."

"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."

"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."

"Routing around slow hardware."

"Some documentation is very hard to find."

More Red Hat Ceph Storage cons

Pricing and Cost Advice

"Our licensing is renewed annually."

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

"The price is a little high."

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

"We used a reseller for the purchase."

"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."

"The price could be cheaper."

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

More Everpure FlashBlade pricing and cost advice

"We paid an additional fee to have Dell's ProDeploy Plus team implement it."

"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."

"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."

"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."

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

"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."

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

More Dell PowerScale (Isilon) pricing and cost advice

"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."

"We never used the paid support."

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

"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."
