VMware vSAN Room for Improvement
Stability can be improved. Adding all these new features is nice, but we are now at the level that most of the features you need in production are there. The stability, 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 uncoupled even more.
Dashboards are there, and we use vROps as well. So, we have all the beauty of the capacity planning and everything over there. That's not really something where we need a lot of other things.

If one node out of your ten nodes fails, it takes a lot of time to replicate and rebalance VMware vSAN. This time can be reduced. When a node fails and the data is not accessible, vSAN has to be rebalanced to make the redundancy level of two again. However, if it is taking a lot of time and any other hardware fails during that time, then we have a problem. Two disk failures mean that all data will be lost, and we may have to recover it from the backup. So, the number of threads that run to do the rebalancing could be more so that the time taken to make it fully redundant again is not so much.View full review »

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.
Increasing the classifiers to maybe more than 64 could be done in future releases.
The file service is something that can be integrated.
Something more could be done to integrate from a monitoring perspective right in the console itself so that we have deeper monitoring capabilities.View full review »
Head of network and web at a maritime company with 501-1,000 employees
We are looking for more load balancing at an application level.
For the hardware level, we're looking at some other solutions. For example, we're checking out Nutanix and Sangfor.
We've had issues with load balancing. Suppose, for example, if the physical ESXi host is down, the virtual machine you have handle manually. We need to have load balancing and RAM and processor balancing also.
Hardware load balancing is available on the enterprise version of the solution, however, it's extremely expensive and therefore out of our budget.
In general, we're looking for more features. This solution doesn't really offer us that much.View full review »

The solution could maybe improve failure protection. The failure protection for vSAN is very expensive sometimes within the clients. The customers want to be able to tolerate two or three nodes in failure. However, sometimes, the budget is limited. Implementing hyper-converged solutions sometimes are very expensive with the dozens of tolerance of failure.View full review »
The price can be reduced. Small businesses cannot afford this solution.
There are limitations with Kubernetes and vSAN.
In the next release, I would like to have a hybrid flash available with this product.View full review »

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.View full review »

I would like to see the availability of more template based VMware systems. Combined with the ability to check and measure multiple and converging data segments. Another issue I've seen is that the tool seems to be slow when first starting up.View full review »

Disaster recovery needs to be improved, when there is a crisis, there is a problem with what is the quickest way to get out of it. This should be done automatically, not manually.
If we have a power failure then you have to find your way manually. There 's no way to automatically fix it. So there should be an automatic way to repair such crises from disaster recovery.
In the next release, I would like to see more clarity on where the files are. the details of the files, for example, where the owners of the files are, and more audits.View full review »
The solution could be improved by having more filtered and multiple view volumes instead of a single view.
In the next release, I would like to see a more user-friendly dashboard with the potential to display issues. It should be capable of detecting the issues faster. For example, if something is wrong with your LAN, controller, or storage volumes.View full review »
Trainer in information and communication technologies at a educational organization with 51-200 employees
I'd like to see improvement in the troubleshooting tools, specifically the troubleshooting mechanism. We like the product, but once in a while there are problems that require us to reboot the host to fix things, and that creates an impact on production.
For additional features, I'd like to see a better monitoring tool.
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.
The pricing for licensing could be cheaper.View full review »

They should provide Deduplication and Compression over the hybrid drives. The Deduplication and Compression are locally only on all flash drives.
When you compare with Nutanix, you will find the performance in the Deduplication and Compression is over hybrid and on the flash drives. This feature is needed in vSan.View full review »

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.View full review »
Senior Manager IT Services at a financial services firm with 1,001-5,000 employees
Its integration with a hybrid cloud can be improved. Its scalability can also be improved so that it can be integrated with more than 32 nodes. The maximum number of nodes is okay, but our use cases could probably do with more nodes, probably up to 64.
In terms of new features, it should probably have the basic support for high-speed networking spaces.
Integration could be better. It should be easier to integrate vSAN with the dashboard you have, with Google, and the others. Better integration is very important because the customers need to put the solution inside their company. It's the same dashboard for AWS, the same dashboard on GCP. It's good to see this inside a dashboard. It's very important.View full review »
There is always a challenge with their firmware. There is different hardware and they are always looking for different firmware that is compatible with vSAN. It is very difficult to find the compatibility matrix.
They need to do some kind of automation in terms of hardware, firmware, and compatibility with the vSAN. They need to do some sort of upgrade for the customer.
I would like to see the upgraded mechanism, and improvements on the hardware so that we can create a VPN.View full review »
