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 performance of FlashBlade is excellent. It does not necessarily leverage the SOS API that some of the newer products leverage, but I found its speed pretty much on par and comparable. It is fast, and it does what it is supposed to do."

"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."

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

"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."

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

"The solution provides many controllers."

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

"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."

More Pure Storage FlashBlade pros

"Features like ransomware protection, file lock retention, and third-party integrations (e.g., Superna for ransomware protection) are significant benefits."

"The most valuable feature of the solution is the unlimited scalability. The tool has high availability and high storage capacity."

"Customer service has been really good."

"Based on the flexibility of the system itself, it was easy for us to manage the growth by buying individual nodes as needed."

"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."

"Our users are able to easily roll back snapshots without going through IT."

"Dell PowerScale (Isilon) is brilliant for scalability and really, really good in that regard."

"Dell has the AI to protect the EMA."

More Dell PowerScale (Isilon) pros

"The solution is pretty stable."

"The scalability feature is used by all users and is critical for our operations."

"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."

"Most valuable features include replication and compression."

"The high availability of the solution is important to us."

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

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

"The community support is very good."

More Red Hat Ceph Storage pros

Cons

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

"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 could be improvements in public cloud integration."

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

"Its configuration should be easier."

"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."

"I have not seen ROI."

More Pure Storage FlashBlade cons

"Dell PowerScale (Isilon) is a little bit pricey, and its pricing could be improved."

"The pricing could be reduced."

"Additional metadata reporting would be great. We have to use a separate tool to report on that. We would like to view the age of data and how long it has been since someone has accessed a file."

"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."

"Since our Dell PowerScale (Isilon) is our own on-prem in-house built system, we don't have many up-to-date resources, and we're still a few years behind."

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

"The solution’s interface and pricing could be improved."

"The improvement should be in AI. Everything is going towards AI."

More Dell PowerScale (Isilon) cons

"Rebalancing and recovery are a bit slow."

"If troubleshooting is needed, the response should be faster."

"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."

"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."

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

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

"Routing around slow hardware."

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