Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"Overall stability is very good. It is a very stable solution."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"The high availability of the product is the most valuable feature."
"What I really like about this program, is that it is easy to use and easy to configurate."
"IBM FlashSystem has an easy to use GUI, similar to the IBM Storewize family, which make it one of the best flash storage systems in the market."
"User friendly management interface."
"The solution allows for easy migrations from previous products or vendors via its embedded storage virtualization function."
"The all-flash storage has tier replication capabilities."
"The GUI is very easy and performance is also good."
"The speed and the ease of installation are the most valuable features."
"The initial customer technical support was efficient and effective."
"The performance monitoring feature is useful as it can report in 15 minute intervals by hour, day, week, month, or by a custom date range."
"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."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"I'd like to see the product implement active replication for vehicles such as VMware."
"I would like to see replication and DR features in the next release of this solution."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"The tool's portfolio is minimal. It is expensive."
"The Data Reduction Pools (DRP) support could be better."
"The interface of this solution could be improved."
"IBM should improve its data reduction development."
"Sometimes the performance is effective but it gets resolved in the process."
"The only issue my team faced was transferring the data from the old system to IBM FlashSystem, which is an area for improvement in the solution."
"The data reduction pool feature sucks and is not recommended for use with heavy workloads."
"The customer's expectations are what they get on the cloud, they're expecting even in the on-premises deployments, going forward."
"The array level RAID does not seem available."
"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."
