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.

Offers cost-effective storage for small companies with budget constraints

IBM FlashSystem 5300 is offered at a very low cost in Israel, which is advantageous for small companies. However, other features like deduplication and compression do not perform effectively. The price sensitivity makes it a viable option for clients with budgetary constraints, as it allows us to secure deals based on the cost rather than advanced performance.

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

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

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

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

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."

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

"The high availability of the product is the most valuable feature."

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

More Pure FlashArray X NVMe pros

"The solution allows for easy migrations from previous products or vendors via its embedded storage virtualization function."

"The performance of IBM FlashSystem is very good. The new technology and high throughput have given us more confidence in the solution. The management of the system has improved and we can control the monitoring system alerts and multiple FlashSystems with the Enterprise Cloud Edition, which is free. The migration of recently stored data to a new flash is much easier. You can move your data because you can utilize it externally."

"One of the valuable features is the performance, it is one of the best in the market."

"It is simple to make an update."

"Data deduplication is one of the most valuable features of this solution."

"The valuable features of IBM FlashSystem include flash copy mapping, which is a procedure to collect instant point-in-time data for testing real data."

"The most crucial feature of IBM FlashSystem is compression."

"The GUI is very easy and performance is also good."

More IBM FlashSystem pros

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

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

Cons

"We need better data deduplication."

"The tool's portfolio is minimal. It is expensive."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"The UI for this solution needs to be improved."

"They could add more support for file storage and different types of storage."

"Maybe the price can be reduced since the solution is very expensive."

"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."

More Pure FlashArray X NVMe cons

"One area for improvement is in the GUI, where host clusters are not properly dealt with. With Hypervisor host clusters, all hosts must see the same volumes in the same order. Using the concept of a “host-group” has been around (even with IBM) for many years, so why not with the V7000?"

"In IBM FlashSystem, data reduction is an area with shortcomings where improvements can be made in the future."

"The deduplication and compression ratio is not very good. It's not reaching a very high ratio."

"The deduplication technology in IBM FlashSystem needs significant improvement."

"The GUI needs some improvement. An additional function that could be helpful is reducing the time it takes to delete volumes, especially if they are compressed or deduplicated."

"The storage capacity of this solution could be improved."

"The solution is not easy to use and could improve."

"Include an option to upload the support package to the IBM ECuRep when opening an IBM PMR."

More IBM FlashSystem 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

"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."

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

"As far as the licensing costs, everything is included in the license."

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

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

"The licensing is on a yearly basis."

"With VMware, we pay $300,000 annually."

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

More Pure FlashArray X NVMe pricing and cost advice

"The cost of the IBM FlashSystem is lower than the HPE solution."

"We have no issues with the price as it is very competitive."

"The tool is cost-efficient."

"I find the pricing of the solution to be very reasonable."

"The solution has good pricing, but it is not cheaper."

"Our customers would like IMB FlashSystem to be less expensive."

"I'd rate the basic licensing and the Virtualize software a ten out of ten, and the extra Spectrum and other an eight out of ten."

"If five is a good price and one is a high price, I would rate the price a two or three out of five."

More IBM FlashSystem pricing and cost advice

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

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

Pure Storage FlashArray//X is the world’s first enterprise-class, all-NVMe flash storage array. It represents a new class of storage – shared accelerated storage, which is a term coined by Gartner – that delivers major breakthroughs in performance, simplicity, and consolidation.

Pure Storage

IBM FlashSystem products are enterprise computer data storage systems that store data on flash memory chips. Unlike storage systems that use standard solid-state drives, IBM FlashSystem products incorporate custom hardware based on technology from the 2012 acquisition of Texas Memory Systems. This hardware provides performance, reliability, and efficiency benefits versus competitive offerings.
