Eric Black

Solutions Architect at Recovery Point Systems

The ability to leverage multi-tenancy along with immutability is a huge benefit for us

The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top. Veeam Backup specifically has started to streamline their API, and they are doing that with SOS API. They have optimized it. Any of the S3 devices out there that support this SOS API can have far more API calls at once. On our side, that translates to better restoration. With SOS API, it can leverage far more restorations at a single given time or read from the device in simple terms. That results in maximizing the output and throughput from the device itself.

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

"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 feature of this solution is performance."

"We can capacity plan at a greater level than we used to."

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

"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 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."

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."

"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."

More Pure Storage FlashBlade pros

"PowerScale allows us to manage storage without managing RAID groups or migrating volumes between controllers. It has really simplified things. We're not having to worry about the underlying infrastructure. That takes care of itself. We just worry about the data. It's really easy for deploying and managing storage at the petabyte scale."

"The capacity and scalability are what I appreciate the most about it; that was huge for us. We saw its benefits immediately after we started using it."

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

"The technical support has been excellent. I would give them a ten out of ten for support."

"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 solution has simplified management by consolidating our workloads. Rather than managing all the different workloads on different storage arrays, Windows Servers, etc., we just have one place per data centre where we manage all their unstructured data, saving us time."

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

"On a scale of one to ten, with one being worst and ten being best, I would rate Dell PowerScale (Isilon) a ten."

More Dell PowerScale (Isilon) pros

"We have some legacy servers that can be associated with this structure. With Ceph, we can rearrange these machines and reuse our investment."

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

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

"It has helped to save money and scale the storage without limits."

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

"I can compare Red Hat Ceph Storage with products from other vendors; I explored quite a few, but I still find that Red Hat Ceph Storage is making the most disruption."

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

"The community support is very good."

More Red Hat Ceph Storage pros

Cons

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

"Commvault has mainly driven the Analytics, providing data and reports. However, the product has room for improvement, especially regarding storage analytics. Upgrading firmware has caused issues, requiring feature disabling to revert to traditional backups. The firmware upgrades sometimes affect Commvault backups."

"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."

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

"The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top."

"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."

"It would be nice if you could store file-based in the same box with the same technology."

More Pure Storage FlashBlade cons

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

"Perhaps if there was a local chatbot built within the system or on the dashboard where we could directly ask for anything on the OneFS, it could help us."

"The solution's rate structure or rate redundancy needs to be improved."

"Perhaps if there was a local chatbot built within the system or on the dashboard where we could directly ask for anything on the OneFS, it could help us."

"The tool's support team and the way the cases are handled by the product's technical support team are both areas of concern where improvements are required."

"Always, there is room for improvement in terms of cybersecurity, as new challenges are continually emerging in the market."

"The cost of Dell PowerScale is currently high and there is room for improvement."

"Improvements could be made on the object storage side."

More Dell PowerScale (Isilon) cons

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

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

"Geo-replication needs improvement. It is a new feature, and not well supported yet."

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

"What could be improved in Red Hat Ceph Storage is its user interface or GUI."

"Routing around slow hardware."

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

"The licensing cost is excessively high. This is a significant issue from my perspective."

More Red Hat Ceph Storage cons

Pricing and Cost Advice

"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."

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

"We used a reseller for the purchase."

"The price could be cheaper."

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

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

"The price is a little high."

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

More Pure Storage FlashBlade pricing and cost advice

"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."

"Price was also a significant factor in our decision to go with PowerScale. The team at EMC, now Dell EMC, came through with a highly competitive offer that tipped the scales towards their solution. There was only one other solution around the same price point, but it could not match PowerScale on features. That other solution is no longer on the market."

"The pricing for this solution is reasonable."

"I always want things to be less expensive. However, I would say the pricing is fair. Their costs are in alignment with their competitors. It is a good value for the money."

"It is a really expensive solution."

"The pricing is excellent."

"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."

"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."

More Dell PowerScale (Isilon) pricing and cost advice

"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."

"We never used the paid support."

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

"Most of time, you can get Ceph with the OpenStack solution in a subscription as a bundle."

"There is no cost for software."

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

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

"The operational overhead is higher compared to Azure because we own the hardware."
