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.

Helps reduce data silos, improves performance, and flexibility

Our customers have seen improvement in performance, space, and flexibility for growth and management of data protection through snapshots and other systems. The AI models are something we are looking forward to trying but are not there yet. The algorithms are specific to each company and their industry. One of the most important things is the data localization. Many scenarios require the project data traffic to be close to where it is generated and read. A lot of interaction is between users and systems. So data localization is one of the most important things in terms of using the data algorithm. We don't need to manage our PowerScale and run its storage from any location yet but it is something that is coming for sure because several customers have centralized data in main data centers. But in different locations across the globe. So this is going to be a topic. I think that through the different functionalities that the Dell platform can grant, it will be a great player. When it comes to the flexibility for supporting various data workloads while protecting them, the combination of PowerScale and PPDM and all the other components of the data protection solution right now is key. So the automatic integration between the products is one of the killer features of the solution itself. PowerScale helped us to reduce data silos. This has simplified the management of large data environments in terms of scalability and management instead of having a different solution for the right reports to see how the data evolves and how to better manage them. PowerScale can do that in combination with the other components of the ecosystem. In terms of risk reduction, We need to mention the data management and the recovery part, So of course, the integration with the data domain is key. The fact that we can rely on these functions, and the fact that we also manage different customers, and possess the recovery plans and tests that can prove the solution is working.

Assistant Manager at Genpact - Headstrong

It's a reliable-high performing solution that lets you customize file security

The file system arrays have multiple nodes, so one node automatically comes up if another goes down. The system should allow the primary node to remain the master node and the secondary node to function as a non-master node. HP has already deployed AI in GreenLake's cloud features, but they should also integrate them into the flash array. None of the HP arrays has a single console. They use two or more controllers, making it challenging to manage them all in a single array. If the controller or the console goes back into an embedded state, it's difficult to track or recover the system that failed.

Quotes from Members

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

Pros

"It's very easy-to-use."

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

"The most valuable feature of this solution is performance."

"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."

"Speed and ease of use are the two most valuable features."

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

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

"The main feature I have found to be product replication."

More Pure Storage FlashBlade pros

"You plug in a new node and data starts migrating over to it, and IT spreads out the load. We've added multiple nodes to the system since deploying it. The process is pretty seamless, and we are able to do it with no downtime. It's a very easy process to do."

"The most valuable features of the solution are flexibility and ease of implementation."

"There are also the policies that you set up on replication and purging files, and policies for something called WORM. That's a "write once, read many," where you can't overwrite certain files or certain data. It puts them in a "protected mode" where it becomes very difficult for someone to accidentally delete. We use that for certain files or certain directories, because we're dealing with video and some video has to be protected for chain-of-custody purposes. The WORM feature works great."

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

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

"I assess the stability and reliability of Dell PowerScale (Isilon) as perfect, as we haven't had any hiccups with it so far."

"Dell has the AI to protect the EMA."

"Dell PowerScale includes a wealth of features that are important from a security and recovery perspective."

More Dell PowerScale (Isilon) pros

"GreenLake for File Storage provides more security, allowing customized security for different file types."

"What I really appreciate about HPE GreenLake for File Storage is its well-organized, packaged platform for running enterprise workloads on the cloud."

"For us, the utilization of cache when the data is traveling between media, from any location to any location or within that cluster, was seamless."

"GreenLake for File Storage provides more security, allowing customized security for different file types. Block Storage can't do that. That's the most intriguing feature I have always looked for in a FlashArray or file system."

Cons

"The solution is expensive."

"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."

"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 would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."

"I would like to see more deduplication."

"It's on the expensive side, as expected for a niche product."

"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."

More Pure Storage FlashBlade cons

"Pricing is an issue. It's quite expensive for the amount of storage we have."

"PowerScale is not suitable for virtual environments."

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

"The legacy file system for Epsilon didn't scale into the cloud and didn't have a separate OS. It would be key if this was made possible."

"The replication could lend itself to some improvement around encryption in transit and managing the racing of large volumes of data. The process of file over and file back can be tedious. Hopefully, you never end up going into a DR. If you do go into a DR, you know the data is there on the remote site. However, in terms of the process of setting up the replicates and filing them back, that is just very tedious and could definitely do with some improvement."

"Dell PowerScale's deployment is not easy."

"There aren't many templates still coming out for it. They need to provide templates so we can copy and paste what we've done in the past to future, new things."

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

More Dell PowerScale (Isilon) cons

"From my standpoint, the single user interface could definitely be improved. It provides a fast head start, but when dealing with complex situations, it doesn't lead you effectively or offer direction on managing these complex workflows."

"There were instances where the system went down due to heavy IO or intense data flow."

"The file system arrays have multiple nodes, so one node automatically comes up if another goes down. The system should allow the primary node to remain the master node and the secondary node to function as a non-master node. HP has already deployed AI in GreenLake's cloud features, but they should also integrate them into the flash array."

"Some challenges with a multi-cloud environment due to some compatibility issues."

Pricing and Cost Advice

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

"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."

"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 of this solution could be made more affordable."

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

"The product is very expensive."

"The price is a little high."

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

More Pure Storage FlashBlade pricing and cost advice

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

"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."

"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."

"It is a really expensive solution."

"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 pricing for this solution is reasonable."

"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."

"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."

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."
