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.

Offers good features like Fusion and stable product with better customer service

Fusion is the only best feature, but it's a very good feature. Nexenta is a very old product. Nexenta is a well-established product used in the UK, US, India, Dubai, Qatar, and other countries. It is very good. The interface is up to date. Everything is up to date. The OS version was recently upgraded to 5.5 FP3. AI features: DataDirect Networks owns Nexenta and has won awards for AI. They continuously work on AI features. DDN also has a product called Tintri Infinia with AI features. And NVIDIA product also has AI features. I look forward to working on those products.

Cons

"I would also like to see better support for CIFS workloads."

"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."

"Its configuration should be easier."

"The features provided for SMB customers are limited."

"Pure Storage FlashBlade should improve on more cloud integration."

More Pure Storage FlashBlade cons

"It is scalable, but only beyond two nodes. If I go for two nodes it's not scalable. I need to build a complete cluster from the beginning if I'm going for two nodes."

"Documentation management could be improved"

"The management tool within this solution could be improved. We would also like to be able to access services like Azure when using this solution."

"Microsoft closed the shared cluster support, which is important for the solution."

"I think the online documentation needs a lot of work and so do the sizing tools."

More Microsoft Storage Spaces Direct cons

"There were some SMB issues, but they were resolved."

Pricing and Cost Advice

"Our licensing is renewed annually."

"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 solution is expensive."

"With the data center licensing and everything that is connected to that, this solution is relatively costly."
