VMware vSphere Scalability

IT Supervisor at WACT
VMware vSphere is a very scalable solution. The only thing is if you are to upgrade, i.e. from ESXi 6.0 to 6.7, you might not be able to use your older servers. I believe VMware will not support these after ESXi 7.0. For newer servers, VMware is scalable. We can always use it at least. The only issue I may have is we may not be able to use our older servers with the newer versions of VMware ESXi. In-house users number about 110 to 115. We have customers that login into our servers. We have web applications that customers log into from outside. Around 2000 to 5000 customers use our vSphere installation per day. We have billing people that are working there with our customers. We have operation people that are in the field that are using various equipment that is connected via wifi to our systems. Then we use the VMware network to carry our own operations and activities. We have customer service people that attend to customer inquiries, to try to resolve customer issues, but are still logged into the same application. There are various roles from read-only customers that want to pick one information or the other about their product on our sites. They don't actually update anything except they want to transact business with us. We use vSphere to help the users as well as to manage users that need information regarding a particular product or report. Users generate various reports from our SaaS/PaaS applications. The staff we currently have are about five in IT. We have the manager, we have infrastructure persons that consist of system and network. We also have a database specialist that manages our applications. Our database specialists also serve as the developers for the application support. We have user support teams. The various support people that we have dedicated for the maintenance of the VMware vSphere deployment is about five in total. We should still be able to support our users, at least, for the next five years. After five years, we may now be thinking of upgrading the infrastructure. This solution is being used every day, i.e. 24/7/365 days a year. We believe that there's been increased usage, but we just implemented it last year. From our plan, we know that at least for the next five years we may not upgrade. View full review »
Senior Systems Analyst at Manufacturing Organization
We're able to scale with density. I think that's the most important part. The clusters are allowed to go to so many nodes. We don't even touch the number of nodes per cluster. We traditionally have multiple fault zones in the data center, really for a comfort level, not because of a technological level. I know we could push the equipment a little bit harder but we generally like to keep things in a comfort zone that is constantly moving northward. So scalability is limitless and we have not really touched the capabilities yet, but we know the capabilities are there when we are ready to use them. View full review »
Brandon Morris
System Administrator at City of Sioux Falls
For our environment, the scalability has been great. I've been with the city for about three-and-a-half years. We had about 100 VMs at that time, and now our account is well over 500 and the solution has simply grown to fit that need. View full review »

David Grimes
VP of Product Engineering at Navisite
Scalability on vSphere has always been important for us, because of the scale at which we operate. We had a client, who maxed out under the VMware 5 limit of 32 hosts per cluster. So, it has been great to see the continued improvements in scalability. At the VM level, the limits are no longer practical impediments. Now, at the VMware cluster level, we're also seeing sizes which can operate pretty much any large client environment. View full review »
Kevin Williams
IT Analyst I at Sacramento City College
So far, we've really enjoyed the scalability of it. The main thing that we have to accommodate for is licensing, making sure that we have enough license to cover our expansion. Otherwise, we just throw a few more hard drives into our server array and make sure that we have enough storage. View full review »
Michael Huset
Senior Systems Administrator at a transportation company with 1,001-5,000 employees
I can always go horizontal, vertical is a little problematic sometimes. Horizontally, being able to add storage on the fly - even hot ad-hoc remove, if we do have some higher workloads or the like - we can always scale that without re-booting, with the newer operating systems. So the scalability portion is always on key. View full review »
Preston Lasebikan
Lead Systems Engineer at a tech services company with 11-50 employees
As far as scalability goes for us, I've run it as far as having up to 100 hosts in the cluster and I haven't noticed any degradation. It's been running well. View full review »
Eric Garrison
Customer Engineer at ATTO Technology
Scalability is awesome because, for us, we do a lot of pods. We create pods and nodes and small clusters to do some of our R&D products. The ability to bring them up very quickly, very easily, without adding lots and lots of additional hardware, and without taking excessive amounts of time, and then tear them down, but just shove them on the back burner in case we ever need to come back to it - that for us is one of the biggest features that we could ever have.

Network Administrator with 5,001-10,000 employees
As long as you got the ESXi hosts with the resources necessary, scalability isn't a big problem. We don't really lock down a lot of our clients which are still within our organization. We don't really limit the resources. If it becomes an issue we'll look at that, but for the most part, it hasn't been a problem. If we look like we're getting a little tight on resources, then we look at getting and setting up a new ESXi host. View full review »
Infrastructure with 5,001-10,000 employees
We have grown our environment, introduced new hosts, taken old hosts out. We have some 1,500 VMs running inside of all of our environments now and that has been a slow growth. I don't know how long it took us to get there, but we've grown to that level and it's never once given us a problem. From the interface, you see how much CPU utilization and RAM utilization that each one of those hosts is giving you. You can tell ahead of time when you need to start expanding the environment. And with VMotion, you expand the environment and then let DRS have at it and walk away. View full review »

Head - Server and Storage at a financial services firm with 1,001-5,000 employees
Its highly scalable, we have never had to make radical changes to the design to make it more, or to put in more capacity. So, as we are growing we have been adding the servers into the existing pool without even worrying about a need for redesign. As we grow, we find that our company is more dependent upon this product.

Raden Evangelista
Systems Engineerineering Manager at a wholesaler/distributor with 51-200 employees
It is very scalable. Soon as I switched to a vSphere environment, ESXi, and vCenter, I was able to buy hardware and add it in. I just had to buy another license, since the infrastructure is there. It takes me a short amount of time to add something that benefits everybody. It scales vertically. In terms of horizonal scaling, it depends on what the requirements are for it. View full review »

Brian Kirsch
Instructor at MATC
I have no issues with scalability. As large as we have wanted to go with as many VMs, we have never had an issue pushing its limits. The majority of the issues are truly integrating it into the Active Directory structures. This doesn't seem to be there yet. View full review »
Christie Brinker
Chief Technology Officer at Keeforce
Scalability is really great. Being able to have a customer who decides, maybe a year after they've purchased their hardware, that they need to add another server because maybe they've decided to purchase a new product - being able to scale that system out really helps a lot. View full review »
Tony Reeves
Network Administrator
Scalability works pretty well. You can start out at a couple of hosts, based on your business needs, your budget. That's probably the base recommendation I would start out at for having some of the DRS and HA failover capabilities. But if your business grows, you can easily add a host and a cluster and expand your capabilities on storage and compute. If you're running vSAN, you can run on the storage side, too.

Rene Van Den Beden
Chief Architect at RoundTower Technologies
It scales very well. Now, with vSphere 6.7, it's 128 hosts. Talk about scale with vSphere is now a non-issue. Typically what we do with our customers is deploy vSan clusters, typically 20 to 30 hosts, because that's a natural failure domain. Going beyond that, it really makes no sense, because you want to have separate failure domains. View full review »

Sajag Chaturvedi
IT Infrastructure Architect at a retailer
We are using it on a big scale. vSphere is one of the biggest product of VMware, and we have around five vCenters with around 80 hosts. Scalability is one of the best things about vSphere. You don't need to change your design if you have a new demand for workloads or if a new product is coming in. Thus, the scalability feature is awesome. View full review »

Sean Crawford
Information Systems Analyst at Sandag
Scalability for vSphere 6.7 has been a major enhancement compared to 6.5. That is because of the technical features they've added that allow you to scale further away from your primary data center, such as vMotion over long distance, etc. It's made things better for us. View full review »
