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.

Shared storage capabilities provide enterprise value with good reliability

Amazon FSx is more costly compared to other storage solutions like EBS or EFS. The auto-scaling feature should be improved, as it currently includes downtime. I need to manually increase the storage, which is not ideal. Integrating FSx with Windows Server is challenging; it's a long process involving Active Directory (AD) setup and synchronization.

HPC CTO at a manufacturing company with 10,001+ employees

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."

"The most valuable feature is Safe Mode."

"The product is scalable and easy to expand."

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

"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."

"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."

"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."

More Pure Storage FlashBlade pros

"FSx operates as an independent service, not tied to any server, which eliminates dependencies between applications for storage."

"I rate the stability of Amazon FSx ten out of ten."

"The shared storage capability is highly valuable."

"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."

"The solution is useful for machine learning and scientific applications, including computer simulations."

"This has been one of the most reliable storage systems that I have ever used."

Cons

"I would like to see better integration."

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

"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."

"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."

"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."

"I want efficiency. FlashBlade doesn't have efficiency now."

"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."

More Pure Storage FlashBlade cons

"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."

"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."

"A direct FTP feature would be beneficial instead of relying on transmission services."

"The write performance could be improved because it is less than half of the read performance."

"The read/write ratio is an area in the solution with some flaws and needs improvement."

Pricing and Cost Advice

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

"The product is very expensive."

"The price of this solution could be made more affordable."

"The price is a little high."

"The price could be cheaper."

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

"Licensing fees are paid yearly."

More Pure Storage FlashBlade pricing and cost advice

"The lowest price I have paid is $370 or $380 per month, while the highest can exceed $3,000 per month."
