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.

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.

"My experience with Dell as a vendor is pretty good; they are probably one of the best in the industry."

"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."

"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."

"Dell PowerScale's performance is good."

"Dell PowerScale has the SmartConnect and SmartConnect Pro features. That's why I like the product."

"Customer service has been really good."

"With Dell PowerScale (Isilon), it uses not just a terabyte but petabytes of data, storing a large amount of data takes within minutes, and you can bring it down to seconds as well, as it does not take much time to upload or copy the data here and there, and upgrades also do not take much time."

More Dell PowerScale (Isilon) pros

"Most valuable features include replication and compression."

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

"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."

"The community support is very good."

"The solution is pretty stable."

"We have not encountered any stability issues for the product."

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

More Red Hat Ceph Storage pros

Cons

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."

"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."

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."

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

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

"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."

"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."

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 itself is capable of very much, but the initial deployment experience can be lacking possibly because it does not incorporate any design phase."

"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."

"The portal is really complicated to figure out features and functions, and it could be easier to navigate."

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

"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."

"It would be good to have synchronized mirroring between two clusters without using a third-party program."

"The analytics could be improved."

More Dell PowerScale (Isilon) cons

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

"The product lacks RDMA support for inter-OSD communication."

"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."

"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."

"We have encountered slight integration issues."

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

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

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

Pricing and Cost Advice

"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."

"Our licensing is renewed annually."

"The price could be cheaper."

"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."

"The price is a little high."

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

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

"I feel that the price could always be lowered."

More Pure Storage FlashBlade pricing and cost advice

"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."

"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's a high-cost offering amounting to three or four million Swedish kronor, or about $400,000 or euros, for approximately 480 terabytes of storage."

"Dell PowerScale is an expensive solution compared to other products like Qumulo."

"It is an expensive solution."

"Dell PowerScale (Isilon) is an expensive solution."

"The pricing is expensive, but I think it's a fair value because it does manage itself. It definitely is much simpler than any of the other scale-out storage platforms that we've looked at in the past."

"The pricing is excellent."

More Dell PowerScale (Isilon) pricing and cost advice

"There is no cost for software."

"We never used the paid support."

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

"The price of Red Hat Ceph Storage is reasonable."

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

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

"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."
