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 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.

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.

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.

More focus has to be put on deduplication and compression with a hybrid architecture. The reason is that some customers need to have a more cost-effective solution so they don't want to implement all-flash. As such, they need to use a hybrid environment.

The solution could use more integration with respect to the DR solution. If there was more integration with respect to the backup solutions, that will definitely help us. On the DevOps side, if there could be more automation it would be more helpful. Specifically, we would like to know how to integrate and extend it towards the cloud. Either it is JCP or GCP or AWS.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

The biggest room for improvement I see in vSAN is the lack of SAN connectivity. I've kind of joked around that there is no "SAN" in vSAN. And it's something that we've worked to try and introduce some options for, and we're going to continue to work towards that.

We are finding vSAN is going down the right path, but vSAN has specific profiles which supports vSAN disk. However, our company has our own storage. So, we have different profiles of configuration. Some of those profiles and motherboards, vSAN doesn't support. We have challenges and work with VMware to work with other providers to get into the VMware list and drivers. Since it's customizable, we are looking for drivers from other vendors as well from VMware for compatibility. There is a room for improvement on the latest version of compatibility with the VMware product, especially for vSAN and with other vendors, like Intel and AMD, on their motherboards and driver configurations.

I see room for improvement with vSAN in particularly in the reporting realm. Now, with vSAN 6.7, they're starting to include vRealize Operations components in the vSphere Client, even if you're not a vRealize Operations customer. So, that's really good. It exposes some really low-level reporting. I would like to see more of that. However, you have to be a vRealize Operations customer to obtain that. I would like to see more include of this included in the vSAN licensing. The vSAN licensing is not an inexpensive product. It does cost more than hypervisor. I would like to see more basic reporting, or even expert reporting. I think with our licensing that we've paid our dues, and we should get the information.

Room for improvement could be in the planning stage of going to hyperconverged. And this is a big ask: some modeling tools or guidance on how to work out the optimal TCO. For example, core size - the amount of RAM that you're running - versus the licensing cost you're up for with, say, Mircrosoft data center, versus the number of hosts you're going to run and have to license for the vSAN. It's quite a complex equation and it's really difficult to work out, in advance of implementing the solution, that you've got it right. That creates some uncertainty around the total cost of ownership.

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.

I know they're working on this: better support for an all-NVME array. Better metrics. vSAN itself is a great storage platform, but one of the issues with it is that you have to be fully locked into the VMware package to use it. We're going to be deploying 72 Kubernetes nodes, and we're not going to buy VMware licenses for 72 of them, just so they can access vSAN. That's what we're using the Pure for. Opening it up so you could have vSAN as a data store, use it as a data lake, hit it with an NFS, S3 from outside the VMware ecosystem, would be great.

You need to evacuate all the data and make sure you have enough space on the host, then add more hosts or take out hosts. That process is a little bit complex. You cannot scale as needed or shrink as needed.

There are features that we could use that are coming out: File Services, data backup, and a better way to do Maintenance Mode with vSAN, which takes a while.

The Snapshots feature looks pretty cool, so that will be nice to have. External storage would be a good thing to have in the next release, something other than iSCZI, something a little more, not HA, a little more production-oriented, than iSCZI.

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.

Perhaps they could provide encryption without having to use an encryption manager.

If you want to get down to the nuts and bolts of room for improvement, we would really like them to look at what Nutanix did for day-one/day-two operations deployment: Bringing in the equipment, getting it deployed, getting it setup, and ease of use of one-click for deploying our 30-node solution. With vSAN we had to go into each one individually and set it up.

The only thing I care about is that the solution is stable, reliable. They need to improve on those factors. I don't want to have to wake up at night to deal with problems.

We want see a better monitoring tool in vSAN. Monitoring is not that great as of now because it shows us false alarms in the Health status. We would like that to be improved.

I would like to see more comprehensive lifecycle management. The current path and process for upgrading or updating the firmware, as well as the storage controller software to interact with that firmware, is fairly manual and not very well documented. A little more time and effort spent on the documentation of the lifecycle management for vSan would be really great.

I would love to see vSAN integrate Persistent Memory and NVDIMMs. I know they're supposed to be working on an elastic tier so that we don't have the issues with destaging from the cache to the capacity. Those are the things that I'm interested in. I'm not an end-user, I'm a partner, we put together proofs of concept for end-users. So my biggest desire is for the VMware/vSAN team to perfect the single tier or what they're calling the elastic tier so that you can pool SSDs as well as NVDIMMs.

I would like to see replication as part of it. I would also like to see direct file access, being able to run SIF shares and NFS and the like. I think that would be critical to continuing the use of it, going forward. One of the things that we've had challenges with is when we place hosts into maintenance mode. Sometimes doing so triggers large re-sync processes which can be time-consuming and which have, at times, pushed the capacity to the threshold. I definitely think making some changes in that area would provide some big improvements.

I would like to see a little bit more documentation on the initial setup, and a little bit more explanation on the expandability: How to extend out your vSAN much more simply through the console because, a lot of the time, you have to do it through the command line.

The usability is pretty good but it could use a little tweaking on the UI, with a clearer definition of exactly what some of the things do. For example, sometimes when sticking hosts into maintenance mode, you have to re-read the definition a couple of times. I have to say to myself, "Okay. I actually want to evacuate the data off of this host. Or no, I actually don't. I want to keep it there but I still put the host into maintenance mode." So a little bit more clear and concise definition of what some of the options do would help.

* I would like more integration with the hardware when it comes to disc types and supporting the newer types of storage. * I would like compression and deduplication to be offered for offloading hardware, instead of doing it with software. That would be nice.

I would like a better Hardware Certification List (HCL). The HCL should a little easier to deal with. Making the hardware compatibility not as much of an issue would be a good thing.

We have been talking to VMware about things we'd like to see and I think they have done them in their 6.6 release. I don't think we need any more enhancements at this time.

I need some additional features, and to learn more, to develop best practices for the Brazilian federal government. I would like to see machine-learning. This is the biggest problem because, in Brazil, our federal government doesn't know about moving to the cloud. We have city, state, and federal governments to move to the cloud. Dataprev is beginning the work towards a private cloud and machine-learning would be an important feature, one I really need.

* Online dedupe * VM disk size limitations vSAN does not have online dedup. When opening the inline dedupe, the performance will be lower than off inline. 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.

Some storage tiering options can be included, like other mature storage systems. Some intelligence can be added to the newest version to provide more flexibility between storage tiers, like Nutanix, to make this product a true software defined storage product.

When it was implemented, we were one of the first to jump into using vSAN for production use. The main problem we had was hardware compatibility, finding the right hardware that was certified. This caused further problems because the hardware reseller had little knowledge of the requirements and we even had issues with firmware from the hardware vendor. This delayed the implementation time by a few months. This should not be a issue today, but still be cautious when choosing the hardware.
