VMware vSAN Scalability

Yves Sandfort
CEO / Cloud Evangelist at Comdivision Consulting GmbH
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 any easy add-on for us. It's easier for us to manage it this way, then with legacy storage, where we would have to add additional disk shelves. View full review »
Paul Letta
Systems Administrator at a K-12 educational company or school with 201-500 employees
We started with a three-node cluster. We are now at a nine-node cluster. We can just add nodes piecemeal as needed to add capacity. It's been very transparent. Users have never noticed when we've had to do that. So, scalability has worked real well for us. View full review »

Jose Fuentes
Infrastructure Architect at a media company with 10,001+ employees
We have 130,000 people connected to the platform and to the servers. Eventually, we want to use the cloud, which will help with the volume. View full review »
Vijayakumar Arumuga Nadar
R&D Architect at a tech services company with 11-50 employees
vSAN is scalable for us. If any additional capacity needs to be included, we just add to the host and configure the vSAN cluster. View full review »
CTO at a healthcare company with 10,001+ employees
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. View full review »
Deron Roberts
Senior Systems Engineer at a manufacturing company with 10,001+ employees
The scalability is very good. If we know that we need more CPU, more memory, we can add more nodes to it. We don't need to do that today but we know, tomorrow, that we have that capability. View full review »
Michael Cayouette
Team Lead System Integration at a tech company with 201-500 employees
We find the scalability very good. We've been able to upgrade very easily as users come on, as we need to create more VDI workstations. Adding the extra drives gives us the capacity we need. View full review »
Joseph Lepek
IT Manager at VelocityEHS
We started with three nodes, added a fourth. It was easy to do, gave us more storage, very scalable. You can just keep on growing and growing. View full review »
Eric Garrison
Customer Engineer at ATTO Technology
Scalability in vSAN has been really good. It's very easy to add nodes in, to automatically generate the drives and the disk groups. It has been a piece of cake, surprisingly so. View full review »
Philip Sellers
Solutions Engineer at a insurance company with 1,001-5,000 employees
I can't really speak to scalability. We have a fairly limited deployment at this point with three nodes, so it's a bare minimum sort of configuration. View full review »
Infrastructure Analyst at a retailer with 1,001-5,000 employees
Scalability: pretty simple. You just add more and away you go. The data sets are constantly growing, so we have internal needs, new VMs are getting spun up all the time. They're gobbling up all kinds of storage space. We try not to over-commit too much, but everybody does, right? But it's constantly growing and we're constantly adding to it. View full review »
Aaron Reiss
Infrastructure Engineer at Boys Town
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. View full review »
Jonathan Bartelson
Systems Administrator at a energy/utilities company with 1,001-5,000 employees
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. View full review »
Barbara MacKenzie
Head, IS Operations & Infrastructure at Sydney Adventist Hospital
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 »
Marcello Collao
Manager Innovation Cross Developer at a comms service provider with 1,001-5,000 employees
We have about 2,000 machines under this solution with about 100 hosts. It can scale beyond what our needs are. We have no problems with scalability. View full review »
Ed Hammond
VP of Systems Operations at Cogolabs Inc.
So far, for scalability, we've just been running it on five nodes at our primary data center, and we're building out a second data center. It's going to be running on five nodes there. We haven't really scaled it up since we built it. View full review »
Kenny Morales
Senior Server Analyst at a healthcare company with 1,001-5,000 employees
We scale it with our test environment. We are looking to do it with Horizon. We are able to scale it to see how many VMs that we can host and how long it will take us to add new hosts, if needed. View full review »
Andrew Harrison
Cloud Engineer at a tech vendor with 1,001-5,000 employees
Scalability is slightly limited in that you're pinned by the physical disks in your hosts, but provided that your solution doesn't require you to have specific disk technology, you can get the size you need and expand it out as much as you need to. View full review »
Matheus Belin
My team is starting to develop and make use of the scalability. The team in Brazil is very big in cloud performance but we are just beginning to move into a cloud program. View full review »

The scalability is very good. You plug it in and it goes. View full review »
System Engineer at a healthcare company with 1,001-5,000 employees
We don't want to enlarge the environment. If we have a new need, we will separate and start a new system. We don't want to have a general-purpose infrastructure. It's not a good idea for our purposes. We value less scalability more accurate assessment as it is not the way in our environment. We don't want to add more nodes to the same cluster, it's not a good idea. We separate it. View full review »
Jason Montogomery
Engineer at a consumer goods company with 10,001+ employees
It scales really well. However, we're going to be in need of some, not external storage, but ways to expand storage without adding additional nodes to the cluster. View full review »
Supervisor at RSM US LLP
We haven't dealt that much with scalability because we're rural. It's a small area with small community-type banks. Being able to convert existing storage into vSan is really a perfect solution for a lot of our customers. View full review »
Server Administrator at a consultancy with 1,001-5,000 employees
We don't scale that much because we have a three-year refresh time. We tend to acquire for how much we predict we will scale up in the next three years. View full review »
Senior Systems Administration at a energy/utilities company with 1,001-5,000 employees
For me, it scales really well. We have multiple product vendors. We're able to leverage all of them using the vSAN capabilities of all of those vendors. View full review »
CTO at a tech services company with 51-200 employees
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. View full review »
Sys Admin II at a retailer
The scalability is fine. Adding new nodes is very simple. View full review »
Solutions Engineer at a tech services company with 51-200 employees
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 »
Damon Howell
Systems Engineer/Partner at a tech services company with 1,001-5,000 employees
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 »
Andrew Watson
Systems Engineer at Colorado college
It scales well. We have plenty of room to grow. It should be a good long term solution for us. View full review »
