We performed a comparison between Dell Unity XT and HPE Alletra based on real PeerSpot user reviews.
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."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The most valuable feature of this solution is reliability."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"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."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"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."
"VMware integration makes the life of our engineers easier, as we are almost 100% virtualized and this feature is used on a daily basis."
"Using this solution has meant that I do not need to look for different partners to provide me with solutions like a backup service. Dell provides end to end solutions."
"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."
"It's an all-flash Unity, With that compression feature, it's comparable to a hybrid. That is one thing that we definitely like."
"The ease of management and “user-friendly” management environment (GUI)."
"It gives me the flexibility with its ability to replicate to itself and the ability to use the Dell EMC Cloud as an option. That's always sitting there and waiting if we need it."
"VMware integration: Grants both the Storage and Virtual Administrator the ability to create and mount datastores, or even to check how much space each VM is consuming."
"This product is perfect for small, and mid-range customers who need to pay less, but still, get enterprise-level capabilities."
"It offers rich features and high speed for transferring data."
"The tool's notable feature is that we don't need to log a case directly with the vendor. The tool has access to all the logs on-premises. This is an on-premises solution. Additionally, we can provision data as thick or thin provisioned. Moreover, it includes data grid duplication and compression features."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"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."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"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 would like to see VNC integration or be able to use Pure Storage with VNC."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"We need better data deduplication."
"This solution would be improved with the addition of flexible raid volumes."
"In terms of what could be improved, I would say its capacity and its connection."
"This product has some scalability issues. Before you can get support, you have to look for the service tag number on your product which could make it difficult to access support."
"Currently, the protocol SNMP is not implemented. That's a problem, as we follow this protocol and I can't check the integrity of this equipment."
"The pricing is a bit high. We'd like it to come down."
"Replication with VMware - it's called the vSphere Metro Storage Cluster - is lacking in the Unity and is present in Compellent."
"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."
"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)."
"It would be better if there were an option to incorporate the NVMe feature alongside other storage tiers. Currently, the system operates on Autotier but can manually peer and mix different types of drives, such as SAS and SATA drives."
"We had some issues while installing it on our servers. It required more resources while cross-checking. So, the initial setup process could be better."
