reviewer1381863
CEO at a tech services company with 201-500 employees
It is quite scalable. We are using it ourselves, and we are providing virtual machines to other customers.
We are using 16 nodes. For creating this storage, we have about 600 terabytes of storage in VMware vSAN in each cluster. If you have to make it several petabytes, then I don't know whether it will work or not, but up to one petabyte, I don't see any challenge in VMware vSAN. I have no idea about the scalability larger than that.
The solution is scalable.

I am not sure about the number of users who use the product since it is mostly used at an application level in our company. I believe that around 10 to 15 applications use VMware vSAN.
The product's deployment was managed by two people in my company.
Scalability is not as simple as expected. While it's okay, there are restrictions and complexities. For instance, you need a minimum number of servers for certain functionalities, making it less flexible to adapt. I don't know the prerequisites listed by VMware that are not allowed.
Initially, you need to have three servers, for example, when deploying the solution. If you want a backup solution, you need to have three servers for that. And if you want to have a mirror of the room, you need to have three more servers. You can't have just two. You need to have three. So, it's not as simple to expand, adapt, or modify due to these strict requirements.
We have around five customers using vSAN.

The solution is scalable.
VMware vSAN offers a robust architecture with various scaling capabilities, enabling organizations to scale up their storage infrastructure efficiently. It provides both capability and performance for different workloads, automatically increasing IOPS based on workload requirements. Scalability is crucial when it comes to allocating resources, and vSAN supports future-proofing up to 64 clusters.
Deploying VMware vSAN is seamless. You simply need to add nodes or increase the capacity of existing ones. Migration processes may vary, but configuring full capacity per node simplifies the addition of nodes, ensuring a seamless experience.
The scalability is excellent because we can expand with more disks if we choose. The expansion is part of the license model which is simple to adjust.
We have approximately 60 people using this solution in my organization. The solution is always running in the background, it is always being used.

For the product cloud, scalability is okay. However, when we try to use a larger cloud, we can add more new nodes into the same vSAN configuration.
Every year, our number of users increases.
View full review »We're actually scaling out right now from several 4-node VSAN clusters to - I think we're going to go to - some 8-, and then eventually 12-, node VSANs. That's one of the really nice parts about it; we'll just be able to scale out. The only downside I think I have with it from a scale perspective is, we've got some hybrid VSAN right now. That's what we all started out with. We really liked the all-flash VSAN arrays that you can get, so we're doing that. However, we can't merge the two, so we have to create whole new clusters for the all-flash VSAN. That makes scaling a little bit rough there, but I don't think that will be much of an issue going forward, because flash is pretty inexpensive now and that's probably going to be the standard from here on out.

VMware vSAN is scalable, if you choose good servers at the beginning with many slots for disks, you can then add disks and extend the storage. You can add memory if you have good servers, and then you can enable your construction. But you have to choose good servers for production from the beginning.

You can say that everything about VMware vSAN is that it is very scalable, making it more than a perfect solution.
Around 500 people in my company use the product. My company manages 90,00,000 endpoints of our clients who use the product.
The product is extensively and regularly used in our company.
The solution’s scalability is good. 200 users are using this solution. We have a private cloud with many intelligent users who can connect to the cloud.
View full review »In terms of scalability, we have to just add the nodes. If you require more computing or storage, you have to add the nodes to the existing cluster. Our clients for VMware vSAN are medium and enterprise businesses.
I rate the solution nine and a half out of ten for scalability.
Scalability for us is an important part of the product because we resize clusters all the time in our environment. We clean them out and actually start from scratch. With vSAN, it's easier for us to add nodes. If in a test scenario that we are building, we currently might have only four or five nodes in the beginning. If we add more, it's an easy add-on for us. It's easier for us to manage it this way than with legacy storage, where we would have to add additional disk shelves.

We're not that large at Boys Town. We probably only have 500 VMs. Realistically we have about 50 VSXi hosts. So for us, it's great because we can just buy servers and expand any cluster we need. We split clusters based on other needs, like licensing or something else. It's not like we get to 64 nodes. So we don't have any issues with scalability. It works great for us.

We'd like to expand in the future. We've tried to utilize it for everything. We can't do that at the moment due to licensing. Not the VMware licensing. It's more due to Oracle.

Barbara MacKenzie
Head, IS Operations & Infrastructure at IM Medical Centre for Health
When talking about scalability, the real value is that, for the first time, I can just build it out one host a time. Over the years, I'm sure everyone has experienced hitting the wall on their array where it's too old or the technology has changed, and they're up for a large sum of money in one hit. The actual, repeatable, non-quantity of the cost to increase the storage, is very valuable.
View full review »It's actually the internal feature that I think gets us the great feature of savings out of it. With VSAN I simply add disk drives and hosts to my infrastructure at any of the facilities I have. The net result is an increase of both storage and processing.
In the older model, if I need to add, let's say a terabyte of space for some particular tier one application, I have to add a terabyte, from let's say EMC, into data center one, a terabyte into data center two, a terabyte into data center three, and if, in my adding of those, I cross one of those magic boundaries where I'm out of cabinet space or whatever, then I have all those expenses. None of that is true with VSAN. In VSAN, I simply add drives into a chassis anywhere in my system. If I need more space, I buy a simple chassis, throw it in there, and continue to add the drives. Much more scalable. There really is no limit to it.

So the more nodes we have the more capacity we get the more performance and there's no downtime. So, it's very easy to scale up, scale-scale out with VSAN and all it takes is a few clicks. It's a very efficient way to upgrade your storage without adding more rack space than you actually need because by having converged storage network in the computer capacity, we don't have to waste rack space which is at a premium where we are in the Caribbean.

Scalability is very easy. We've already run into one scenario where we've needed some more storage. We were able to provision the drives, slide them into our current hosts in that cluster, and expand it. It was very easy.

Regarding the scalability of the solution, you've got 64 nodes into a stretched cluster for VMware. Nutanix goes a little bit above. The only problem is that due to licensing things, such as when you have Oracle and other things, what you tend to do is multiple clusters in order to avoid licensing costs.
The biggest network I have implemented was 16 nodes.

It has its quirks but the scalability is good. Given that you have to have the hardware, the right driver, the right framework, and so on, it's not easy to put it together, it's not a plug-and-play solution. But once you get all of that done, it becomes a good product.

I haven't had any issues with scalability, but I think historically it supports only 64 nodes. It's a VMware limitation, but in our deployment in Sri Lanka, hardly any customers use that many nodes. If you consider that aspect, then scalability is okay. The largest customer we have here uses two nodes.
For Nutanix, there is no such limit as far as I know.

Sometimes our clients find the scalability to be lacking and it affects performance. They're not sure, if they scale up, how much performance they will have left afterward.
Our clients are small to medium-sized businesses typically. They aren't to big.
I'm not sure if any of our clients plan to increase usage. It's hard to predict, due to the pandemic situation. The majority of my customers don't have plans to upgrade or acquire some additional equipment.

I would have liked it to have been more scalable. It's scalable but not as much as, for example, the ScaleIO systems were or the Kaminario. We looked at Kaminario but that was a risky technology, so we didn't want to go there. I think vSAN is okay. It could use a bit more work on the scalability. I think that's key.

I've seen it scale up to large databases. I've got some customers who utilize a small vSAN cluster for their Exchange environments because it keeps it encapsulated for them.
View full review »No. It's no problem. To be honest, we have not upgraded any vSAN infrastructure to date.
I just had to increase the capacity of a cluster in production by a simple addition of hosts, from the moment the compatibility with the existing one has been checked, there are no problems.
Adding this very simply by drag and drop from the host to the vSAN cluster, beforehand, the host must be placed in maintenance mode. Then, we have more than to add the HDD and SSD to the cluster vSAN in place -- either they are claimed automatically or manually. It all depends on the cluster configuration.

Data Center Engineer at Strategic Solutions of Virginia
The scalability is much greater than the current SAN that we're on because we're technically locked in to a certain number of discs and a certain number of performance and so the scalability is drastically improved. We currently have a four node cluster and we're going to be just incrementally moving off of our legacy SAN.
UPDATE: We expanded our cluster to five vsan nodes however we are now in process of retrofitting four legacy hosts for a total of nine vsan nodes.
View full review »Considering I've only done one VSAN cluster, I'd say that the scalability is good. We haven't yet tried to add more clusters.
Our company currently has 20,000 users and we expect further growth, so we'll likely have to scale down the road. That said, I don't anticipate really any issues with scalability at that point.

Adding new nodes and expanding vSAN forward is simple and non-disruptive for a lot of our customers. It makes it simpler so we are not doing late night deployments, and we can answer the needs of the business immediately.
View full review »We have not had scalability issues.
View full review »Scalability is not a major issue with vSAN. The latest version can scale up to 64 nodes per vSAN-enabled cluster. The nodes can be configured to be very dense when it comes to CPU, memory and local disk configurations. A majority of the 2U servers out there contain up to 24 slots (SSD or HDD). All-flash configurations provide more disk capacity thus making the solution more dense. Scaling the solution is also very easy. Scale up or scale out; it all depends on how the solution was initially sized during the design phase.
View full review »Scalability on vSAN is extremely easy. If the host is compliant with the prerequisites (one SSD and one spinning disk), it will be accepted by the cluster instantaneously. All raw storage will be committed to the vSAN data store and directly available for usage.
In terms of sizing the cluster, as deduplication and compression are only available on all-flash arrays, this can heavily impact the storage capacity of the vSAN cluster.
Since we chose a hybrid-configuration, the lack of deduplication and compression caused a storage growth that exceeded the limits quite rapidly. We had to scale up and address the issue in other ways.
I have not encountered any scalability issues; very easy to scale.
