We performed a comparison between Dell SC Series and Dell Unity XT based on real PeerSpot user reviews.
Find out in this report how the two All-Flash Storage solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"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."
"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."
"The latency is good."
"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."
"Technical support has been helpful and responsive."
"The solution is very straightforward to set up."
"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."
"They have a feature called Live Migrate; it's been very, very useful."
"Easy management of volumes: You can create volumes and easily assign them to VMware clusters, increasing their size."
"We see very low latency with very high IOPS for mixed workloads."
"The interface is easy to use which makes the product user-friendly."
"A valuable feature is the performance of the auto-tiering. It will move hot data up to your fastest Tier 1 or move your slow data down. Data progression is what it's called. With the auto-tiering you can have multiple tiers, you can have your Tier 1 be either spinning or flash, all the way down to 7.2K. It will change the RAID on the fly so your writes come in at RAID 10. After they sit for a while, they get converted to RAID 5, then they'll cool off and move down the tiers. Your performance is kept going, while the cold data is moved to your slow, non-performance tiers."
"With auto-tiering, it's easier to understand than most arrays, knowing that all of your writes go to the tier that you specify, with easy-to-create storage profiles."
"Connecting it up, you can run it within a few hours."
"I find this version to be more budget-friendly compared to products from other vendors. This aspect greatly benefits my customers. It's highly advantageous due to its affordability. The operational aspect is also noteworthy. Additionally, its availability and performance are commendable. The speaker are also equally powerful."
"It has improved the utilization of our own internal resources and performance across our managed service platform, meeting our customers SLAs."
"The most valuable aspects of this solution are its stability, performance, and ease of updating."
"I like how it separates the iSCSI drives from the standard shares. It has two different routes to it. I know most of the other solutions do this, but I just like the way that Dell EMC does it."
"The most valuable feature of Dell Unity XT is data duplication. Additionally, the management interface is simple, and is not a hassle using it. You don't need too much to learn or to be familiarized with it."
"Unified block and file storage without the need of control stations and data movers. This simplifies administration and deployment and requires less rack space."
"For sites that we use it on, it gives us more flexibility and high availability solutions. It is easier to expand the site, if needed."
"The most valuable feature of Dell Unity XT is its support of protocols for both block, and file levels. It has the features a store solution should have."
"User friendly interface"
"We need better data deduplication."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"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."
"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."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"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 next release, I would like to see real-time analytics for further insight into consumption models."
"The initial setup is somewhat complex and should be made simpler to do."
"From a performance point of view, it's getting a bit old."
"The connection should be better integrated with the network to offer a better view of the system."
"An issue we had was that the controller went down during an upgrade because of their upgrading the code. One side of the switch was down."
"We had times that we needed a file service solution. We've used FluidFS, but it's a solution that is being transitioned out."
"I would like to see higher compression, dedupe, faster I/O, and bigger drives."
"One option I would like to see is, when you're up on the view-screen, to be able to incorporate getting to what HPE call the iLO, the Integrated Lights-Out. To be able to get that instead of having to go back and trying to find IP addresses and re-institute those would be good. It would be good to be able to that put on the initial splash screen."
"The ease of use could be improved. It took me a while to learn it."
"Improve the interface and provide more management capability."
"Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."
"It's not as reliable as it should be, I think it was probably released a little early. We've had production problems with customers, and there are still some challenges at scale as well. Compression is a problem for the system. Once you enable dedupe and compression, the performance of the system, the capability, halves... It has to be right-sized and sized for compression, but even with that, because there are only two storage processors, you're ending up at almost 40 percent usage."
"The one thing that we would look at would be if they were to expand the file level features, just to give us a balance or a tier between it and Isilon options out there, for unstructured data."
"Improve the administrative user interface so it is easier to work with. Currently, a simple task, such as removing a host from 100 LUNS, takes a lot of time. If they could improve LUN to host model to be more like the EMC VPLEX, for example, it would be great."
"It is expensive, and the pricing could be better."
"Issues with slow responses from the support team."
"My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint. We were trying to run some commands just to see how the storage snaps were interacting with the storage array, and it was a little difficult to look up exactly what commands should be run. The Help files detailing what exactly the commands did wasn't as detailed as we would have wanted them to be."
