We performed a comparison between Dell PowerMax NVMe and VAST Data based on real PeerSpot user reviews.
Find out in this report how the two NVMe All-Flash Storage Arrays solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."It has good, reliable, fast storage."
"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."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Technical support has been helpful and responsive."
"Overall stability is very good. It is a very stable solution."
"The latency is good."
"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."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"CloudIQ has become an optimal tool for us to get the full picture of all the different arrays, from mid-tier all the way up. It gives us that single view and the ability to launch the Unisphere. That is really is powerful in being able to manage the array."
"Enterprise Cloud Storage is the most valuable feature, along with the data services which come with it, plus the deduplication and compression."
"The optimization of the cache memory of each engine and the use of persistent memory."
"We are most interested in cloud utilization."
"You can use PowerMax for all workloads and consolidation. We have used it to scale thousands of VMs."
"The response time, compared to XtremIO, is far better."
"PowerMax, with version 9.02, which we installed recently, has some very good features, such as CloudIQ."
"We like the compression, dedupe, and I/O on the PowerMax. They are better than on the XtremIO."
"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."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"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."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"The tool's portfolio is minimal. It is expensive."
"There is room for improvement in the pricing of the product."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"I'd like to see the product implement active replication for vehicles such as VMware."
"It is on the expensive side."
"Although they call it unified storage where you have SAN and NAS, with a NAS implementation on top of a SAN, the NAS implementation is a little complicated and clumsy. As SAN, as block storage, it is very powerful... If they could provide a very good NAS implementation, it would be better, so that customers don't have to look for other simple solutions for NAS."
"We would like more documentation, a guide to the features of the PowerMax."
"It's a relatively new product, but for the next release I would like to see higher bandwidth on the front-end adapters. This would allow even greater scalability for critical workloads and consolidation for non-critical workloads. The hosts may not require that level of I/O performance today. However, it allows us to scale physical non-cloud environments without large investment."
"I would like to see more development in the cloud environment. It would be good if it comes in the cloud kind of setup."
"Dell PowerMax NVMe is costly compared to other solutions."
"The technical support is lacking. We are working with Dell EMC to get some better understanding of this."
"Since the merging of EMC and Dell into Dell Technologies, there has been a hurdle that they've had to overcome, and they're not over it yet. It takes two to three times longer for things to get fixed than it did when they were separate companies. That is something that has to be fixed."
"Firmware updates are a bit painful because you have to involve their support, as opposed to having the ability to do it yourself."
"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."
