"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 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."
"Xtrem10's features are more simple to implement. The integration and interface are also good."
"The Metro clustering and solid-state performance, are the most valuable features of this solution."
"The performance is good, which is important."
"The most valuable feature of Dell EMC XtremIO is the data protection (DP) group, it is one of the most advanced features in these types of arrays. The dedupe and compression that this array provides both do a superb job."
"A valuable feature of XtremIO is that, in terms of administration, it's simple and manageable."
"Provides good performance as well as integration with deployment tools."
"The most valuable feature for our customers is vMotion. It allows them to shut down virtual machines and migrate them to others servers."
"We can also create test cases. We can even throttle down performance or release more performance. So, we can run more precise test scenarios."
"The solution is stable."
"The most valuable features of VMware vSAN are that it receives updates frequently, has good compression, optimized storage, and they provide webinars on what is new. Additionally, the integration with third-party products is good and it is easy to manage."
"The technical support is good. We are always thankful for the technical support from VMware. They are very supportive when we have a technical problem."
"This product has very good performance when it comes to virtualization storage and works well with solutions such as SAP HANA, Exadata, Hadoop, and Big Data Analytics."
"Good performance, reliable and agile."
"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."
"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."
"I would like to see the ease of deployment and built-in Metro clustering."
"XtremIO needs to be lower priced. It also needs better endpoints and scalability."
"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."
"In the next release, the solution could have better integration and if we can host assets on the cloud, such as NetApp has the NetApp volumes, which we can host on the cloud directly called NetApp CVO (cloud volume ONTAP). Dell EMC should come up with something purely on the cloud rather than manage services."
"Scalability is something that can be improved because there is an issue when it comes to mixing versions."
"VMware vSAN needs to improve its features because other solutions have more advanced features."
"I have used the VMware Replication but I can't get it to work properly. The process should be simplified."
"They can package it in a way that is specific to the hardware infrastructure and the hardware platform. It should stay fairly up to date with the drivers and the manufacturer issues. The problem with uncoupling the proprietary technology and component capabilities is that by uncoupling them, you run into some concerns or challenges over the poor performance model. These concerns really come when you start talking about high performance, high bandwidth, and high availability types of environments. While vSAN is a leader, in a critical view, it is not about being cost-effective. It is more about the immediate impact of money loss to the business in critical applications where we want to maintain a continuous operational 59 model. It is, however, good for QA/QC tasks. I don't necessarily know how it works in regards to VDI or virtual desktop infrastructure."
"They should provide Deduplication and Compression over the hybrid drives."
"There is a lot that VMware could improve from a marketing perspective. The cloud is still new for many people, so extending storage should be effortless. It shouldn't be so complicated to extend the storage so workloads can access it no matter where they go."
"The stability needs to be improved."
"I would like to see more support for applications. I think currently it only supports applications between two vSAN clusters."
"Integration could be better."
