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.

Senior Infrastructure Specialist at a healthcare company with 10,001+ employees

Manages large data sets efficiently with hybrid cloud integration

My organization is quite large, with about 30,000 employees. The growth has been substantial in areas such as radiology and genomics. One of the best features we've utilized recently is offload to cloud pools due to capacity constraints on-premise. We didn't want to expand Dell PowerScale (Isilon) straight away, so we utilized cloud pools to offload some data to Azure. That's really saved us in certain areas as we didn't have funding to expand Dell PowerScale (Isilon) until next year, which is why we utilized the cloud pools functionality to offload.

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

"It uses the same platform for connectivity so integration is seamless."

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

"Using this solution has made our backups more reliable."

"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."

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

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

"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."

"The most valuable features of this solution are the rewrite speed and the nonstop services."

More Pure Storage FlashBlade pros

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

"The stability of the solution is good."

"I assess the stability and reliability of Dell PowerScale (Isilon) as perfect, as we haven't had any hiccups with it so far."

"The solution provides massive performance, scalability, efficiency, and ease of management."

"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 most valuable feature of Dell PowerScale is its scalability."

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

More Dell PowerScale (Isilon) pros

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

"We use the solution for cloud storage."

"Stratus allows more reliability than all the other types of computers available."

"Most of the features are beneficial and one does not stand out above the rest."

"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 has simplified my storage integration. I no longer need two or three storage systems, as Ceph can support all my storage needs. I no longer need OpenStack Swift for REST object storage access, I no longer need NFS or GlusterFS for filesystem sharing, and most importantly, I no longer need LVM or DRBD for my virtual machines in OpenStack."

"radosgw and librados provide a simple integration with clone, snapshots, and other functions that aid in data integrity."

More Red Hat Ceph Storage pros

Cons

"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."

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

"Pure Storage FlashBlade should improve on more cloud integration."

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

"It's on the expensive side, as expected for a niche product."

"I would like to see more deduplication."

"In my opinion, one way Pure Storage FlashBlade can be improved is by having more compatibility between the FlashArray and FlashBlade, allowing for synchronized data between both platforms."

"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."

More Pure Storage FlashBlade cons

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

"The product needs to improve CLI since commands are complex. The search option is also difficult since you must give the full path."

"Dell PowerScale's deployment is not easy."

"There aren't many templates still coming out for it. They need to provide templates so we can copy and paste what we've done in the past to future, new things."

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

"They should add some new services that should be for on-premises, and more analytics should be there for the data, allowing for a deep dive from that analytics, which is currently missing."

"PowerScale is not suitable for virtual environments."

"I would want to see more AI features with Dell PowerScale (Isilon)."

More Dell PowerScale (Isilon) cons

"Please create a failback solution for OpenStack replication and maybe QoS to allow guaranteed IOPS."

"The management features are pretty good, but they still have room for improvement."

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

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

"The storage capacity of the solution can be improved."

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

"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."

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

More Red Hat Ceph Storage cons
