Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."The deduplication and compression rates are beyond impressive."
"I like its speed. It has all the features that I need."
"Scalability is one of the best features. You can quickly add more. You can swap out the drives with larger sizes, you can add more shelves. All of that is perfect - the whole concept of keeping it modular..."
"We've had to use tech support on a number of occasions. They did everything remotely and talked us all the way through. They fixed the issue within 30 minutes. Every single time we contact them, they're perfect. I would give their technical support a ten out of ten."
"The most valuable feature is replication."
"The most valuable feature is its upgradeability."
"Data deduplication features make it easier to manage storage and forecast growth."
"The speed is one of the most valuable features of Pure Storage FlashArray."
"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."
"VIOLIN QV2020 is the latest in terms of performance. It has high-speed data access and processing capabilities, distinguishing it as a leader in its storage solutions category."
"It’s simple to use hardware to fix performance issues. Our issue is poor coding/queries. This greatly speeded things up. It’s too costly to track down poor programming in applications. The price of a developer’s time to scan through all the coding is high compared to buying Violin."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"They could improve the price."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."
"A three wave application or multi wave application synchronization would be an improvement."
"Pure Storage FlashArray could improve in the area of cryptographic information in the consoles. The user-friendliness could improve. The Pure Storage FlashArray team should come and log into the system with their maintenance credentials and then pull out the information as evidence of cryptography."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"There are many features which need to be added, particularly on the replication side."
"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."
"I set up Wi-Fi for storage, and since then, we haven't experienced any interruptions in service."
"VIMM replacement is poorly designed. You have to slide out an entire drawer, remove the cover and then pop out the failed VIMM. I would like to see a front replacement just like with hard disks. This leaves room for error; for example, when you slide it out from the rack, you are moving cables along the cable management arm. This leaves the possibility of accidentally unplugging a cable from the array if it is not seated properly. Also, you might pinch the cables when sliding it back into the server rack."
