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.

Eric Burgueño

High-Performance Computing Services Manager at The New Zealand Institute for Plant and Food Research Limited

Simplified data management, tremendously reducing our users’ cognitive overhead

The only thing that I think PowerScale could do better is improving the HTTP data access protocol. At the present, you cannot protect access to data via HTTP or HTTPS the same way that you can secure data access through other protocols like NFS or SMB. You can either access a file because it can be access by anyone in the organization, or you cannot at all. There is no in-between. HTTP is not considered a first-class data access protocol, so the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply. However, with the recent introduction of S3 starting from OneFS 9, I believe the necessary plumbing is already there for HTTPS to also be elevated to a first-class protocol in the future because both protocols sit behind a web server under the hood. It does not sound like it would be too complicated to implement, but it would be a valuable feature and it is currently missing.

Quotes from Members

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

Pros

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

"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."

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

"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

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

"I would rate Pure Storage FlashBlade a ten out of ten."

"The onboarding and integrated monitoring tools are pretty good."

"The initial setup is pretty easy and simple."

More Pure Storage FlashBlade pros

"Its scalability has been huge for us."

"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."

"I don't have to rebuild the cluster to add a node."

"The solution is stable."

"This has been a valuable solution for our business overall. It offers business continuity and replication features."

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

"The tool's most valuable features are scalability and stability."

More Dell PowerScale (Isilon) pros

"Without any extra costs, I was able to provide a redundant environment."

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

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

"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."

"The ability to provide block storage and object storage from the same storage cluster is very valuable for us."

"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."

"Most valuable features include replication and compression."

More Red Hat Ceph Storage pros

Cons

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

"The speed could be improved."

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

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

"Its configuration should be easier."

"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."

"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."

More Pure Storage FlashBlade cons

"Because of the magic that it does 'under the hood,' it is very difficult to find out within the system where all your storage is going. That's a little bit of a ding that we have on it. It does so much magic in order to protect itself from drive failures or multiple drive failures, that it automatically handles the provisioning and storage of your data. But by doing that, finding out why a file of a certain size, or a directory of a certain size, is using more storage than is being reported in InsightIQ, is very difficult to discern."

"If they integrated some functions, as they have on Data Domain with a cyber recovery vault, it would be ideal."

"Dell PowerScale needs to reduce its price."

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

"Improvements could be made to reduce the costs and the high level of knowledge needed to maintain and use them. We had old hard drives with moving parts in Dell PowerScale, and due to this, we must switch to a more efficient environment with all-flash."

"Its configuration needs to be more straightforward."

"Dell's customer service needs improvement."

"The solution’s interface and pricing could be improved."

More Dell PowerScale (Isilon) cons

"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."

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

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

"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."

"This product uses a lot of CPU and network bandwidth. It needs some deduplication features and to use delta for rebalancing."

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

"It takes some time to re-balance the storage in case of server failure."

Pricing and Cost Advice

"Our customers have seen a reduction in TCO."

"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 price could be cheaper."

"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."

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

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

"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 is a little high."

More Pure Storage FlashBlade pricing and cost advice

"The platform is not cheap. However, on the software side, you can choose what you want license. So, you can start your licensing with the features that you need, then after buying the platform add some other features."

"Pricing for this solution is reasonable."

"The pricing for this solution is reasonable."

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

"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."

"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."

"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."

"Our company finds the pricing high, but it decreases over time."

More Dell PowerScale (Isilon) pricing and cost advice

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

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

"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."

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

"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."

"There is no cost for software."

Reviews from Real Users

Dell EMC PowerScale storage stands out among its competitors for a number of reasons. Two major ones are its scalability capabilities and its user-friendly centralized management system.

Rachel B., a chief operations officer & acting CFO at Like a Photon, writes, "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."

Keith B., the director of IT at NatureFresh Farms, writes, "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."
