Sales Manager at Multicomputos PR

Helps to save money and resources with the data compression feature

One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Storage Engineer at Movate

Good customer service and support and suitable for large environments

It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

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

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

"On a scale of one to ten, I rate Pure FlashArray as ten."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"The latency is good."

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

"Everything, especially the VMs inside, is pretty fast."

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

"The solution is scalable."

More Pure FlashArray X NVMe pros

"It provides a combination of all the protocols that you need, without losing deduplication and compression."

"It performed great originally, and when it performed great, it was awesome."

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."

"The initial setup is straightforward."

"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."

"We use IntelliFlash products for larger environments, like Qatar Airways."

"Data Compression: Up to 80% space reduction in the database"

"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"

More DDN IntelliFlash 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

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

"In the future, I would like to see integration with enterprise backup systems."

"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."

"It is on the expensive side."

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

"I'd like to see the product implement active replication for vehicles such as VMware."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

More Pure FlashArray X NVMe cons

"It's somewhat scalable, but maybe not so much as some of the competition."

"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."

"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."

"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."

"Snapshots are not as easy to access as on a NetApp device."

"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."

"In future releases, I look forward to more AI features."

"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."

More DDN IntelliFlash 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

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"The licensing is on a yearly basis."

"The product is expensive."

"We pay approximately $50,000 USD per year in licensing fees."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."

"The support cost per array is about $20,000 a year for 24/7 support."

"Our licensing fees are $500,000+ USD."

More Pure FlashArray X NVMe pricing and cost advice

"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."

"I think we pay around 100 grand per year for three arrays or four arrays."

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

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