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.

Managing efficiently with user-friendly interfaces for monitoring and managing resources

We normally recommend Dell ECS to enterprise customers and government customers Dell ECS is very easy to handle, primarily because the web UI dashboard and everything is very easy to manage for every customer. They can monitor the DPS, access failures, bandwidth, failed requests, and latency.…

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.

"It is very easy to use, and it is very fast."

"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."

More Pure Storage FlashBlade pros

"It is a stable platform."

"Dell's technical support team is good."

More Dell ObjectScale pros

"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

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."

"Its configuration should be easier."

"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."

"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."

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

"The features provided for SMB customers are limited."

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

"The documentational aspect of FlashBlade needs improvement."

More Pure Storage FlashBlade cons

"There is room for improvement in the DPI reports, as they could be made more user-friendly."

"Dell ECS needs to improve its performance."

"They need to ensure that the system will work if a site goes down."

"The graphical user interface should offer more options, and the documentation with respect to administration could be improved, as it is quite weak in this product."

"It is a good solution, except for the cost."

"They could provide centralized reports."

"Dell ECS is not fully compatible with S3, as it supports around ninety percent of S3 APIs, which can be improved. Additionally, sometimes there is an issue with memory where it hangs, and they can improve garbage collection, which takes up a lot of space during cleanup."

"There are some limitations with integration with certain cloud providers, particularly with Google Cloud Platform in Saudi Arabia."

More Dell ObjectScale cons

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

"The price is a little high."

"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."

"Our customers have seen a reduction in TCO."

"We used a reseller for the purchase."

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

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

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

More Pure Storage FlashBlade pricing and cost advice

"The price of Dell ECS should be reduced."

"The charges for this solution are made in blocks of models, which are purchased depending on what features an organization requires."

"The solution's cost is quite reasonable."

"The product is quite expensive."

"It is an expensive solution. There is a need to make yearly payments towards the licensing costs attached to the product."

"We are not paying for the license at this stage."

"If I remember correctly, Dell ECS is an appliance, so if you buy Dell ECS, you also have to buy the hardware, while IBM is standalone software, so you can buy IBM as software only without needing to buy the hardware. On a scale of one to five, I'm rating the pricing for Dell ECS a four."

"The solution could be cheaper."

More Dell ObjectScale pricing and cost advice

"Price-wise, VAST Data is not the cheapest, not the most expensive one."

"We acquired VAST Data as a one-time, capital purchase."
