We performed a comparison between Dell Unity XT and VMware vSAN 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."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."
"It has benefited my organization because it has reduced time to insights."
"Overall stability is very good. It is a very stable solution."
"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."
"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 initial setup was extremely simple and straightforward."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"What I really like about this program, is that it is easy to use and easy to configurate."
"It is scalable, and we usually recommend Dell Unity XT to small and medium companies."
"We are happy with the way we have Dell EMC Unity XT configured."
"The replication is big for us. We use file services on Unity and it has a really nice file services interface. It's also easy to manage. It's really easy in terms of provisioning, replication. There are no real tricks to it. It's just easy."
"The most valuable feature is the performance. It's still an all-flash array at a good price point."
"Provides good provisioning, allowing us to save space."
"I like its performance and support."
"The Unisphere management interface: We are very familiar with it. It manages all the EMC devices that we have. Management is easy because it is part of Unisphere, which is self-learning."
"We have Dell EMC engineers helping us out and doing some over the shoulder training. They are working with our customer right now doing data migration over to Unities from the legacy Oracle stuff. While they're doing this, they're showing people how the Unities work and the ins and outs of the software interface."
"The most valuable features of vSAN are its simplicity to deploy and that we can use commodity disks in our servers without complexity or need for external storage arrays or storage specialists on our teams."
"The solution fits well with my requirements."
"It completely removes the need for a storage network and for a storage administrator and all of that infrastructure and the costs that are involved with them."
"It's completely hyper-converged, so it's very convenient."
"VMware comes with different stacks like VMware Cloud Foundation, which is integrated with different VMware modules. There's interoperability between VMware products."
"vSAN is scalable for us. If any additional capacity needs to be included, we just add to the host and configure the vSAN cluster."
"It is scalable, overall. If you need to add storage, it makes it easy to scale by adding additional hard drives into the existing servers or you can add storage by just adding more servers."
"Scalability in vSAN has been really good. It's very easy to add nodes in, to automatically generate the drives and the disk groups. It has been a piece of cake, surprisingly so."
"The UI for this solution needs to be improved."
"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 pricing is higher than competitors."
"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."
"In the future, I would like to see integration with enterprise backup systems."
"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."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"We would like an AI feature that would protect the backup and minimize the consumed space so we can maintain the quality of the backup. This would help us minimize our IT cost in terms of the backup procedures."
"There is room for improvement in manufacturing."
"We've got massive issues at the moment with IBM AIX. It's not stable. We have a lot of disk errors, production crashes sometimes."
"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."
"It would be great if the solution could integrate an NVMe disk."
"The only challenge I've ever had was with a Drive firmware upgrade."
"This is a tier-three solution and it gives us what we need for archiving and backups."
"It is expensive, and the pricing could be better."
"It needs to be vanilla. There shouldn't be any custom drivers, any custom anything. It should just be, "Hey, you know what? These drivers are going to work for this version, the next version, and the following version after that." That's the difficulty in this. It takes too much upkeep... The main issue is drivers. Every time we move to a new vSAN version, we're having problems finding the correct drivers for the vendor."
"It doesn't seem like it gives the performance that an actual SAN would give for heavy IOPS, read/writes."
"The platform’s pricing needs improvement. Additionally, there should be an appliance module included in it."
"In a future release, they could add micro-segmentation or security level features integrated into vSAN."
"The biggest room for improvement I see in vSAN is the lack of SAN connectivity. I've kind of joked around that there is no "SAN" in vSAN. And it's something that we've worked to try and introduce some options for, and we're going to continue to work towards that."
"I would like to be able to limit IOPS."
"Disaster recovery needs to be improved, when there is a crisis, there is a problem with what is the quickest way to get out of it."
"When you upgrade the vSAN, there are some issues like lost data and problems with the log. The log disappears. When you upgrade the solution, you must have several logs, so if you have some problems, you can check the log server to find them."
