MikaelHellström - PeerSpot reviewer
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.

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 - PeerSpot reviewer
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 solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."
"We have seen a reduction in the total cost of ownership by around 20%."
"The onboarding and integrated monitoring tools are pretty good."
"As a Pure Storage platform, the cost-benefit is hugely based on the deduplication and capacity."
"I would recommend this solution to other interested companies because it's extremely fast."
"It uses the same platform for connectivity so integration is seamless."
"The most valuable feature of this solution is performance."
"It is very easy to use, and it is very fast."
"What I appreciate about Dell PowerScale (Isilon) are its best features: it supports both file and object storage, and it is very easy to manage."
"PowerScale helps our clients consolidate data storage and multiple applications onto a single platform for easier manageability."
"My experience when deploying Dell PowerScale (Isilon) was very straightforward, as we had Dell come on site to do all the actual setup, which was a big help."
"My advice to other companies considering Dell PowerScale (Isilon) is that it takes a little time to understand the product, but once you have it set up and running, it will run stable for all its lifetime."
"The flexibility and the user-friendly interface are the most valuable features."
"The technical support has been excellent. I would give them a ten out of ten for support."
"The solution allows me to use SSMDS to store data for end users and share it within different locations."
"Our main goal is to do disaster recovery with whatever solution we use and Isilon makes it pretty simple to replicate those workloads over to our secondary data center."
"It opens doors for completely open-source cloud."
"Replicated and erasure coded pools have allowed for multiple copies to be kept, easy scale-out of additional nodes, and easy replacement of failed hard drives, and the solution continues working even when there are errors."
"We have not encountered any stability issues for the product."
"Companies that can afford completely flash-based pipe servers should go for Ceph because it's a very performance-intensive, brilliant storage system, and I always recommend it to customers based on its benefits, performance, and scalability."
"The ability to provide block storage and object storage from the same storage cluster is very valuable for us."
"Ceph has simplified my storage integration, as I no longer need two or three storage systems since Ceph can support all my storage needs, replacing OpenStack Swift for REST object storage access, NFS or GlusterFS for filesystem sharing, and LVM or DRBD for virtual machines in OpenStack."
"Without any extra costs, I was able to provide a redundant environment."
"The setup is very easy, deserving a ten out of ten."
 

Cons

"The features provided for SMB customers are limited."
"It would be nice if you could store file-based in the same box with the same technology."
"Compared to, for example, Hitachi NAS, the solution is not mature at all; it's just in its infancy as far as technology goes."
"I would like to see the licensing fees improved as well as the price per terabytes."
"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."
"I would like to see more monitoring capability included 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."
"There could be improvements in public cloud integration."
"There are some missing features in the product, especially when our company needs to do some tape backup, and we see that the tool doesn't have integration capabilities."
"We used to have a chat feature available on the support site. It's not available to us anymore."
"The solution isn't suitable for small environments or small customers."
"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."
"Technical support could be improved. Whenever we have a hiccup, we'd like to get it fixed maybe quicker."
"Dell PowerScale needs to reduce its price."
"The product’s expansion capacity, pricing clarity, and ease of use need improvement."
"The cost of Dell PowerScale is currently high and there is room for improvement."
"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."
"In the deployment step, we need to create some config files to add Ceph functions in OpenStack modules (Nova, Cinder, Glance). It would be useful to have a tool that validates the format of the data in those files, before generating a deploy with failures."
"Rebalancing and recovery are a bit slow."
"In the deployment step, we need to create some config files to add Ceph functions in OpenStack modules (Nova, Cinder, Glance). It would be useful to have a tool that validates the format of the data in those files, before generating a deploy with failures."
"I would like to see better performance and stability when Ceph is in recovery."
"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."
"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."
 

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."
"The price could be cheaper."
"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."
"Our licensing is renewed annually."
"The pricing for FlashBlade is between cheap and moderate."
"The price of this solution could be made more affordable."
"Our customers have seen a reduction in TCO."
"We used a reseller for the purchase."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"This solution is priced slightly higher than others on the market but does offer good quality. With this solution's data reduction and compression, we were able to purchase less. Costs have dropped because of the data rate of compression and deduplication."
"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."
"The pricing is excellent."
"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"The price of Dell PowerScale (Isilon) is reasonable."
"The solution is expensive; it is not the cheapest solution out there. If you look at it from a total cost of ownership perspective, then it is a very compelling solution. However, if you're looking at just dollar per terabyte and not looking at the big picture, then you could be distracted by the price. It is not an amazing price, but it's pretty good. It is also very good when you consider the total cost of ownership and ease of management."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"Most of time, you can get Ceph with the OpenStack solution in a subscription​​ as a bundle.​"
"The price of Red Hat Ceph Storage is reasonable."
"I rate the product’s pricing an eight out of ten."
"The price of this product isn't high."
"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."
"The other big advantage is that Ceph is free software. Compared to traditional SAN based storage, it is very economical."
"The operational overhead is higher compared to Azure because we own the hardware."
"We never used the paid support."
