Quotes From Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
"The high performance is very valuable, as well as the enterprise reliability features.""There's lots of flexibility in how we use the resources while also maintaining a small footprint.""We have been able to consolidate storage into Pavilion. Pavilions are our only SANs because it is a bring your own disk solution. When new drives come out, we are able to take out half of the drives in the system, put in new drives, move our VMs over to the new drives, take the other drives out, and populate those with new drives. Then, we are suddenly twice as dense as we were before. NVMe flash is only going to get denser and cheaper so we can make use of that every couple of years by just throwing newer disks into it at a fraction of the cost of a new SAN."

"The most valuable feature is the integration with vCenter.""I have had no problem at all. I think this is one of the most important things. It is very good. Maintaining it and deploying updates require very low maintenance. We haven't had problems. We had to replace a couple of disks in all these years, but it was pretty straightforward.""I have found Dell EMC Unity XT to be stable.""Initial setup is a simple process.""The high availability of Dell EMC Unity XT has been the most important feature.""The feature that I have found most valuable is the unified storage. Also, its capabilities for block-access, file access, and the center box.""Integration is easy with this product."

"Technical support is good.""The solution fits well with my requirements.""One of the valuable features of vSAN is it has a universal type of technology that allows you to deploy it on any server or hardware. Competitors, such as Nutanix, provides the AOS and can be deployed only on certified hardware. For vSAN, it does not require any kind of certified hardware.""I have found the solution to be scalable.""The solution is easy to use.""It is easy to work with, easy to handle, and easy to manage.""I like the tolerance of VMware vSAN.""Everyone uses virtualization to more efficiently utilize hardware resources. That's the main point of vSAN and VMware."

Cons
"I would like to see the management layer improved.""In our current configuration, we can only run the line controllers in high availability, active-standby mode, whereas we would like to see active-active implemented.""The rail system that Pavilion uses to mount up into a standard Dell or APC cabinet extends further back than normal rails, and they cover up the zero PDU slot. So, I don't like the rail system that comes with the device. That is my biggest complaint."

"In terms of what could be improved, I would say its capacity and its connection.""Issues with slow responses from the support team.""In terms of what could be improved, I would say the deduplication part, because for large deduplications, you need an extra appliance to do it in order to avoid having problems in performance. I think that could be improved, because everything should be included in the product, not with an appliance from the outside.""Support Responsiveness & time to fix bugs should be improved.""The interface and configuration could improve.""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."

More Dell EMC Unity XT Cons »

"Troubleshooting tools could be improved.""The price can be reduced. Small businesses cannot afford this solution.""We would like to see even more storage capacity.""The interface is a little complicated, it could be simplified with more graphical gadgets. We have many servers, and the built-in functions, such as rate configuration, are a bit complex.""Reporting currently depends on third party applications and that could be improved.""There is always a challenge with their firmware.""Its price could be improved. It is too expensive for our clients.""I am looking for more of a software-defined storage platform that uses different protocols, such as iSCSI, NFS, and CIS, and maybe also has an object as part of that. They should 100% make it more of a storage-based product where it is not linked just to VMware, and it also has NFS and iSCSI built-in at a scalable level. They should turn it more into a dedicated storage-as-a-service platform instead of just being built into the VMware kernel. Their level one and level two support is not at all good, and it should be improved."

Pricing and Cost Advice
"This is hardware. They have a singular array that you can populate with your own disk, or you can buy the disks through them. For controllers, you pay for the components inside of the SAN, but there is only one chassis that they work with.""The licensing fees are very reasonable."

"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive.""Pricing for this product is manageable, though slightly higher than comparable products."

More Dell EMC Unity XT Pricing and Cost Advice »

"For a classical node plus storage solution, the price is higher.""VMware vSAN is a little bit expensive and we pay annually. We have an educational institute where we receive discount prices from VMware. We do receive a reasonable discount but it's still expensive.""ROI from an administrative perspective is clearly much better because I only have to deal with one user interface.""I would like to use more advanced models of the solution but the price needs to be reduced. There are some extra costs for this solution including a license.""This solution requires the purchase of a license.""It is fairly cost-effective for entry to mid-level performance based on the underlying hardware components.""We pay for a license to use the solution through our company CapEx and then we continue to pay annually.""The price of VMware vSAN is expensive and there is an annual license required."
