We performed a comparison between Dell Unity XT and Dell XtremIO 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."Technical support has been helpful and responsive."
"It has benefited my organization because it has reduced time to insights."
"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."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"The initial setup was extremely simple and straightforward."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"The NAS is also extremely easy to set up."
"We just recently started using the Dynamic Pools, so while it's scalable, we actually find it valuable that we can just pop in one or two drives when we need to, instead of having to add a whole RAID set. That has actually been very handy for us."
"It is easy to manage. A lot of the system manages itself."
"The solution allows for easy, useful replication with good features for VPLEX and VIVO."
"The scalability is really good now that they have the Dynamic Pools. We don't always have the money to buy complete write sets when we have to expand the storage, so now with the Dynamic Pools we can add disks on the go."
"It is very stable."
"The most valuable feature is the performance. It's still an all-flash array at a good price point."
"It's easy to manage. We access it and manage it through Unisphere and have had no issues. We're able to provision storage, create consistency groups, create RDMs for our virtual machines. Creating it through Unisphere, it automatically adds the data store on the VMware side and rescans the LUNS. We just have to add and configure the storage in one place and it takes care of everything, which is very handy."
"Very good IOPS performance"
"The solution's most valuable features are the inline data reduction and deduplication."
"Ease of management, aside from the serious performance, is the best feature."
"The guaranteed sub-millisecond response time for a 4K block."
"The feature I like most about Dell Xtremio is its hardware quality compared to other vendors. It's clear they're continuously improving their research and development."
"The most valuable features are that it is fast and reliable."
"Initially, we faced numerous issues with our analytical systems. However, we saw performance improvement after the implementation of the solution."
"The speed is extremely valuable."
"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."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"I'd like to see the product implement active replication for vehicles such as VMware."
"They could add more support for file storage and different types of storage."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"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."
"The tool's portfolio is minimal. It is expensive."
"The UI for this solution needs to be improved."
"Firmware Upgrades in EMC Unity require you to manually download OS and Drive firmware, this should be integrated (Nimble does this). When you order an EMC Unity, you have to specify the block size. This is weird for me and even weirder that you cannot change this afterwards, you should be able to specify per LUN/datastore (Nimble does this as well)."
"Dell EMC Unity XT should present a path or a roadmap on how they could put their products on the cloud. This would have some value for their current customers."
"VNX used to have some features that Unity still doesn't have. From that perspective, the progress is not that advanced."
"We are running VMware, and with the VNXe it was possible to restore. We're using Veeam for VMware backups and with the predecessor, it was possible to mount a backup or restore a backup from a storage snapshot. With the Unity 300, this is not possible."
"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."
"We've also encountered an issue when it comes to migrating to compressed LANs on the Unity, and during the Storage vMotion. It appears that the compression algorithm is overwhelmed, and when it becomes overwhelmed it just stops compressing and writes the raw data to the destination. We later copied internally another Storage vMotion to another compressed LAN and achieved much higher compressions on that internal copy. It would be really nice if there was a way to automatically throttle, as a part of a Storage vMotion, to say, "I want to gain the maximum benefits from the compression algorithm, so throttle back the Storage vMotion to implement 100 percent compression.""
"Recently, they released products, sometimes without proper testing, it seems."
"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."
"I would like hardware capacity additions to be a little more flexible. The upgrade path for the existing XTremIO units requires you to purchase 2 XBricks at a time and they need to be the same capacity as the existing XBricks."
"The solution needs to be simplified. When you integrate your storage with other systems, could use a little bit of automation."
"I believe having more replication options comparatively to VMAX (other than RecoverPoint) would be great."
"We've encountered challenges in integrating other products with Dell Xtremio, as it tends to be more vendor-locked. This means we can't easily explore other solutions that might work alongside Dell."
"They can improve the product by providing an HTML5-based interface instead of the Java GUI based application."
"If you are looking at flash storage solutions, XtremIO doesn't offer any unique features. Most of my customers are migrating their workload from XtremIO to other formats because of this."
"Sometimes we don't get an immediate response from the support team. The initial POC also took a lot of resources."
"The physical architecture could use some higher levels of redundancy."
