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.

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.

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.

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

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

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

"The tool's most valuable feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."

"My advice for anybody considering this solution is to go by the business needs, as opposed to just choosing the fastest solution."

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

"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."

"It has good flexibility and stability, it's easy to manage and the response time is good."

"FlashBlade offers low latency, high throughput, and seamless scalability."

More Everpure FlashBlade pros

"The most valuable feature of Dell PowerScale (Isilon) is all the capabilities together."

"Its scalability has been huge for us."

"The solution's flexibility for supporting various data workloads while keeping them protected is great."

"We would highly recommend PowerScale; we've been very happy with our overall experience."

"The tool comes with cheap disks and works fast for video content."

"PowerScale helps our clients consolidate data storage and multiple applications onto a single platform for easier manageability."

"Certainly, we have seen return on investment and peace of mind, especially with our two clusters that are linked together, where one is a disaster recovery solution for the other."

"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."

More Dell PowerScale (Isilon) pros

"The product spawned a new vision of storage deployment, as well as a strong interest in reusing equipment and increasing ROI."

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

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

"I really like that Red Hat Ceph Storage can be used as a total solution without any storage area network components."

"We use the solution for cloud storage."

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

"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."

"Ceph’s ability to adapt to varying types of commodity hardware affords us substantial flexibility and future-proofing."

Cons

"The solution is expensive."

"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."

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

"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."

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

"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 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."

"The integration with S3 needs some improvement."

More Everpure FlashBlade cons

"The initial setup for this solution is complex."

"The solution can be integrated with an automation system. Dell uses another framework developed in-house. They can integrate it with machines."

"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."

"Data storage performance needs to be improved."

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

"From the disadvantages perspective, if I need to replace a drive, I must shut down that node."

"PowerScale is not suitable for virtual environments."

"We had some issues with level 1 support. We had to fight with them on repeated issues. There is room for improvement in level 1 support."

More Dell PowerScale (Isilon) cons

"Ceph Storage lacks RDMA support for inter-OSD communication. That is a huge loss in terms of performance."

"Areas of Red Hat Ceph Storage that have room for improvement include more promotion. Many people do not know about the Stratus case, which is one of the most reliable systems available in the world, but they are not aware that a system can keep working even if there is a hardware failure."

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

"Routing around slow hardware."

"I have encountered issues with stability when replication factor was not 3, which is the default and recommended value."

"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."

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

"Routing around slow hardware."

Pricing and Cost Advice

"Licensing fees are paid yearly."

"I rate the tool's pricing a seven to eight out of ten."

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

"I understand that it is competitively priced compared to other brands."

"The price could be cheaper."
