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.

Architecture Department at Supermicro Computer

Good performance and reliable but the setup is complex

We would like to see a self-sufficient installation. Nowadays it's open-source, but the installation is still tied to the vendor, which means it is unlikely that it is going to scale. I want them to tap into the broader community. It is really emerging, they have a year over year, 50% annual growth. With a 10-year-old company, it will certainly bring a lot of interest, and will certainly make it more successful, if they tap into that growing customer base. They have to make themselves relevant to the industry. The industry is totally geared to the Cloud, DevOps, and geared for agility. The software with the appliance in my set is already outdated, and it is not that it cannot sell, but it has to be tapping into the emerging and growing sectors to continue with the customers and businesses. This is what the requirement is, to improve their technology. Which means that they have to make themselves relevant to the industry.

Quotes from Members

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

Pros

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

"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."

"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."

"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."

"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."

"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."

More Pure Storage FlashBlade pros

"Dell PowerScale's performance is good."

"Customer service has been really good."

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

"The fact that we were able to set it up, use it, and, for the most part, didn't have to worry about it after we had it set up has been valuable."

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

"The flexibility and the user-friendly interface are the most valuable features."

"I would rate Dell PowerScale (Isilon) as a product a ten out of ten."

"Dell PowerScale overall is easy to use."

More Dell PowerScale (Isilon) pros

"Workflow is easy to manage and maintain."

"The technology is stable which is good."

Cons

"The speed could be improved."

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

"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."

"The documentational aspect of FlashBlade needs improvement."

"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."

"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."

"I would like to see better integration."

"I would like to see more VM-Aware features in the next release of this solution."

More Pure Storage FlashBlade cons

"The price of the solution could be reduced."

"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 support offered by the product is an area of concern where improvements are required."

"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."

"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[...]the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply."

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

"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."

"If I could improve one thing on Dell PowerScale (Isilon), it would be better object storage as it recently breached into S3, and that capability could be broadened."

More Dell PowerScale (Isilon) cons

"Lacks some ability to integrate with different systems."

"We would like to see a self-sufficient installation."

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."

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

"Our licensing is renewed annually."

"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."

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

"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 is a little high."

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

More Pure Storage FlashBlade pricing and cost advice

"The pricing is excellent."

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

"It is a really expensive solution."

"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 an expensive product with a high storage capacity suitable for large data requirements."

"The price of Dell PowerScale (Isilon) is reasonable."

"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."

"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."
