VMware vSAN Room for Improvement

Yves Sandfort - PeerSpot reviewer
CEO & Majority Shareholder at Comdivision Consulting GmbH

Stability can be improved. Adding all these new features is nice, but we are now at the level where most of the features you need in production are there. The stability is not from a day-to-day operations perspective, but more from a supportability perspective, because currently some of the support scenarios require you to completely evacuate hosts or the complete cluster. That sometimes can be a stretch. This would clearly be an improvement if the support teams were given additional tools to make that easier.

Upgradability could be a bit easier sometimes. We are now where vSAN can be updated without ESXi, but there is still enough dependency. So that would be good if that actually would be uncoupled even more.

Dashboards are there, and we use vROps as well. So, we have all the beauty of capacity planning and everything over there. That's not really something where we need a lot of other things.

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. We are currently researching to figure out if we can achieve that. 

It's possible that we'll need to acquire new infrastructure for the new data center. And for that, we need to consult some architects, whether it's a VMware architect or some AWS and Azure architects. And we could come up with a workable blueprint that to use as a guideline so we can manage our infrastructure.

The updating process could be easier. It's just a bit more complex. I don't update very often. It's something I do infrequently, and therefore, we haven't got that much experience with it. That said, this Lifecycle looks better. There's a new feature called Lifecycle, which is dealing with the issue sI mainly have.

I haven't done an update yet with the new system. My understanding is it's an improvement from what I can see. 

Guests that are pinned to hosts for various reasons, for antivirus or the backups should be able to be reported that they are being pinned, and also reported if things have snapshots. When you're doing certain things, they don't work so well if you've got snapshots on or if you've got things that are pinned. They can't move. When you're doing things, if there was something that was going to stop it from working that's within VMware, these should automatically be checked.

It could have some automation. We haven't involved ourselves in a lot of automation around the vSAN environment capabilities. We're still running it using a very traditional setup. So, there could be some plugins to automate it using third-party environments, such as Jenkins.

We were trying to explore a solution for a hybrid setup, and VMware had proposed something, but we wanted to understand a deeper setup where our existing vSAN and our HCI environment can interact better with our platforms on the cloud in AWS. So, there should be those types of interactions wherein we can better explore cost-saving opportunities from some platforms in the cloud versus the one that we have on-prem.

I would like to see more support for applications. I think currently it only supports applications between two vSAN clusters. I heard that VMware is planning to have applications using vSAN at the hypervisor layer. I'm not sure whether it's available or it's being planned for the next release. I would prefer it to be on the storage layer than on the hypervisor layer.

VMware is currently working on quite a lot of improvements and they're coming out with lots of novel features in their new releases. There's only one improvement area, and that is it needs a little bit more software and hardware to make it similar to Nutanix.

The pricing could be better when it comes to renewing the licenses. 

Technical support could have a faster response time.

It's hard to come up with an exact feature that might be good to include in a future release, as each customer is different and each customer likely has different feature needs.

If we have some complicated issues, you have to use the command lines interface. Not everything is possible to be fixed in the GUI. This is a drawback, that some things have to be fixed via command-line interface and should be able to be done in the GUI.

There is room for improvement in vSAN's ability to debug. When it's not working well, debugging becomes quite challenging. Identifying issues when it's lagging or not functioning properly can be difficult.

In future releases, I would like to see the ability to debug as a solution.

Other areas of improvement include pricing and support.

When designing the implementation for vSAN, I have noticed that it requires a minimum of six nodes, and this creates a problem when it comes to maintenance. If, out of the six nodes, I put one node in maintenance mode, then vSAN does not create other VM components. I think the reason for this is that the minimum configuration is a six node arrangement. If any one of the six nodes is put into maintenance mode, we're simply unable to create a VM, but if there are seven nodes in that cluster, then we are able to put one under maintenance. That's one thing that should be looked at.

More generally, the features of vSAN as we see them are dependent on the quality of the storage, since each different storage technology has its own separate features that go along with it.

The big thing is pricing, and the rest of it is mostly good. From a scalability point of view, scaling the storage from network or compute should be easier. It is again all around the cost, and it would be good if it was easier to scale your storage separately from your compute. One of the things that I have observed is that when you start off, you've got too much storage, and over time, you've got less storage, and you have to build new clusters to scale. So, if you can scale compute and storage, it would be good. I know it is scalable separately, but it is a complex process.

On the troubleshooting front, it was occasionally difficult for me to perform some troubleshooting. We are currently working in a demo environment, so we are not encountering many issues. However, when you reach production with a heavy load, troubleshooting the vSAN may become difficult. 

Troubleshooting with vSAN is an area that needs improvement.

Based on my testing, I would like to expand deduplication to include hybrid deployments and not just for all-flash deployments.

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. 

When you're moving a workload, you don't want to worry about whether the storage will be there or not. Ideally, that should be easily replicated and extended to a cloud environment. We have a lot of vendors trying to extend their on-prem infrastructure seamlessly. That could be workloads. It could be extending the virtual hardware to on-prem storage or the physical storage to virtual storage in the cloud. Everything should be easy for customers to consume and configure, but some of this stuff is still pretty complex because it's so new.

Compatibility with the previous version, stability, performance, and upgradeability of the solution with the previous version all need to be improved. 

In future releases of the solution, I would like to see more HCL compatibility lists, less hardware requirements, better performance, and the ability to upgrade from the previous version.

This solution could be improved by having more than one controller for the environment. VMware depends on one controller for the whole environment, whereas Nutanix has one controller for each node. Because there is only one controller with VMware, if there was any drop, then the whole environment would stop working. In Nutanix, I have five nodes—there is one controller for each node and it depends on a virtual controller—so if the controller of any node is down, the whole environment will still work.

Many VMware products are specialized, where one solution does one thing and another does something else. It would be better if VMware consolidated these products and offered modules or add-ons instead of selling 10 different solutions.

Also, a vSAN cluster must have compression and deduplication to be an all-flash array, but it's not supported with a hybrid array. Deduplication and compression work better with an all-flash array, so I think that VMware should give customers the option to activate and support this feature for hybrid arrays. Other products like Nutanix support this.

I don't recall an area for improvement in VMware vSAN, because it's a concept, a brand, and a product. If the concept doesn't change, we can't improve this software that much, but VMware can probably make the monitoring feature much better.

VMware vSAN could improve by having faster reload time and a single point of failure. Resynchronization of many hardware could be better. If you have an outage of a disc or a full system, the replication time is too slow. This has room for improvement.

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. But this solution has some improvements, like its snapshot feature. When you have to upgrade the version, vSAN makes a snapshot, and if there is a problem, you can revert to the old version.

Lead Engineer at IBS Platformix

The architecture of vSAN is not good. vSAN works with objects, such as disks, and it causes problems with availability. When we send users caches we lose the total cache disk of the group. It's really a red line for using vSAN. We don't lose all the data because it is replicated in other groups, but when the object is lost in one group, we only have one remaining and this creates a higher risk of losing data.

Another is the restrictions of using deduplication and compression, it requires all-flash for it meaning that deduplication is on for all clusters and you can't control it for specific ones. I would like VMware vSAN to give hybrid configurations more caches and to add deduplication and compression for hybrid configurations.

We often run out of space but we have enough capacity for memory and CPU. It's difficult to find the balance between storage and memory CPU.
