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.

"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."

"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."

"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."

"The tool's most valuable feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."

More Pure Storage FlashBlade pros

"On a scale of one to ten, I would rate Amazon FSx a ten."

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

"The shared storage capability is highly valuable."

Cons

"The documentational aspect of FlashBlade needs improvement."

If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."

More Pure Storage FlashBlade cons

"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."

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

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

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

"The product is very expensive."

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