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

"Rackspace OpenStack is stable and reliable, often compared favorably against other solutions."
"Administrators are very comfortable with the functionality and services OpenStack offers."
"The documentation was plentiful and very helpful.​"
"It created a reusable library with OpenStack features."
"I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."
"The solution is stable."
"There are many services that can be directly used which are not available in VMware."
"The open-source nature of OpenStack provides significant value."
"Good performance, reliable and agile."
"It scales well. We have plenty of room to grow."
"When we do to do more scaled load testing, we can run more dense workloads and still have the same results across all specific nodes"
"The solution is quite stable."
"All the features are working great."
"To me, VMware is a leader of the visualizations. I think everyone just follow VMware."
"The most important thing is the simplicity of the product. It is a well-established product with good stability."
"Technical support has been fantastic. We always get answers quickly whenever we call."
 

Cons

"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."
"It could use more examples in different languages (API use cases).​"
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
"OpenStack's UI, while user-friendly, could be improved to offer a more intuitive experience."
"The line migration is a problem."
"The pricing of Rackspace is quite high in the Vietnam market."
"VMware has a side-to-side replication feature, which is still more mature than Rackspace OpenStack's which can't be used in a production environment."
"The updating process could be easier."
"I would like to see better integration between the cloud and our VMware virtual environment. We only have one virtual environment, which is VMware vSAN. Right now, there is little interoperability with the cloud solution at the moment."
"Because of virtual storage, the system reaches reserve storage for its functions. It also consumes a certain amount of storage, which then results in the creation of a fault tolerance for the system. All of this adds to a lot of capacity being consumed in terms of storage for each drive for vSan. I find this to be one drawback of using vSan."
"Lacks an integrated backup solution."
"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."
"The technical support, it's not satisfactory. Whenever we raise a ticket it takes a lot of time to have an engineer get involved sometimes, or we receive a less experienced engineer. We then have to repeat the situation to the next engineer which all takes time."
"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."
"It would be much improved if we could somehow integrate a better backup with it. Right now, we're using Veeam and it's okay, but I would like more of a VDP vSAN solution. That would be excellent. The VDP, at least the last time we looked at, it was just not quite there."
 

Pricing and Cost Advice

"I use it as an open-source tool."
"The pricing is low."
"Its price could be improved."
"ROI from an administrative perspective is clearly much better because I only have to deal with one user interface."
"We pay for a license to use the solution through our company CapEx and then we continue to pay annually."
"Basically, vSAN is a license in addition to that of the classic VMware Vsphere, which is also mandatory."
"It is not a subscription model. It is a purchase model, but it is very important that you also buy technical support from VMware. This is probably the only disadvantage of vSAN. It depends on the use case, but it can be very expensive."
"This solution is expensive. Nutanix provides us with Acropolis Operating System (AOS) along with its hardware, while VMware provides vSAN, vCenter, and vSphere which all have separate licenses and costs."
"The cost is expensive. I purchased two servers. The hardware cost was $19,000. The software cost for these two servers, including the vSAN, was $30,000, which is $11,000 more than the hardware. Then I had to pay another $5,000 for installation and implementation for professional services. In total, it was $54,000 for two vSAN Servers."
"The licenses are very expensive. The renewal of licenses has extra costs attached to it."
