Managing mixed RAID workloads has improved data protection and delivers strong performance
VMware vSAN can be improved in certain areas. In cases involving our large data stores with large VMs, we experience some latency, not during normal operation, but during database backup operations. We observed latency due to buffer issues from the top-of-the-rack switches. These issues are mostly network-related because all storage data traffic travels through the network. I have recently used Nutanix, and I observed that Nutanix provides better performance than VMware vSAN due to its data locality features. VMware vSAN is now providing data locality, but we did not use that option. If VMware vSAN provides additional features in the next release, such as the VM balancing feature called DRS on the cluster that VMware previously had, it would be beneficial. With DRS, VMs can move easily from one node to another within the same cluster. Nutanix does not provide that flexibility. When placing a VM on a cluster in Nutanix, the placement uses a balancing component. After that, the VM remains on the same host. If any contention occurs on the CPU or memory side, the VM stays in place until contention happens. If issues occur, the VM migrates to another host while transferring all objects to the same host. This is how their data locality is maintained. When a VM moves to any host, it moves with all VM objects. VMware vSAN does not currently offer this option. If a VM moves to another host, it accesses the disk object through the network, which increases latency. VMware vSAN now offers an option to select data locality, but it does not function like Nutanix. This is why some latency remains. If VMware vSAN can improve this feature, it would be very helpful and VMware would regain its top position.

Quotes from Members

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

Pros

"The most valuable feature is the customization. With the customization you can really give the customers what they want."
"The initial setup isn't too difficult."
"The documentation was plentiful and very helpful.​"
"Administrators are very comfortable with the functionality and services OpenStack offers."
"Rackspace OpenStack is stable and reliable, often compared favorably against other solutions."
"The open-source nature of OpenStack provides significant value."
"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."
"I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."
"The solution is stable."
"The ability to have an HA cluster in the absence of a shared storage device or SAN."
"Technical support has been fantastic. We always get answers quickly whenever we call."
"vSAN can help customers save on storage system costs, and also save on the human cost."
"The most valuable features for us are the ability to scale out the nodes independently, and the flexibility of the nodes. We can put almost any type of server in there with our connectivity and everything works great."
"There is not a lot of maintenance required."
"VMware vSAN is easy to implement in a VMware environment and it is not expensive."
"vSAN provides default HA configurations, where if any host goes down, the VM moves around within the host. Even though the disks are local, the VMs moves around with the vSAN disk and vSAN provides a high availability on its own."
 

Cons

"The pricing of Rackspace is quite high in the Vietnam market."
"It could use more examples in different languages (API use cases).​"
"The deployment process could be easy."
"The line migration is a problem."
"The pricing of Rackspace is quite high in the Vietnam market."
"OpenStack's UI, while user-friendly, could be improved to offer a more intuitive experience."
"So for the main stability, there have been a couple of issues that I've experienced."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"Ease of administration is one area where vSAN could be improved."
"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."
"The monitoring feature in VMware vSAN could be better."
"This product is very expensive."
"Currently, one of the available features is shareable VMBKs. You can create the VMBK disc and you can make them shareable between the ends. But as soon as you start using this feature, you lose the ability to create snapshots."
"The stability needs to be improved."
"Virtual machines disk size cannot cap more than a single node. For a VDI user, it may not save enough to hold a file server or exchange server on a single node storage space."
"There's a lot that can be done to segregate. That may be available now in vSAN 7, I suppose, however, the deduplication and compression can be segregated."
 

Pricing and Cost Advice

"I use it as an open-source tool."
"The pricing is low."
"With the new pricing model, it's expensive for the customer."
"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."
"VMware vSAN is an expensive platform. We purchase its yearly license."
"I would rate the licensing model a three out of ten, where one is expensive, and ten is cheap."
"The price of vSAN could be lower."
"The price is okay."
"​I would like to see this technology be made available to smaller businesses, who might benefit from high availability but struggle with the entry fee.​"
"The only problem I have with VMware is the price. It is a good product, but it is expensive."
