VMware vSphere Stability

IT Supervisor at WACT
The stability is good. Previously, our whole infrastructure couldn't support our operations. We are always having downtime, we are always having system instabilities. Since we implemented a new solution with vSphere, we have a greater capacity of infrastructure relative to our virtualization that almost doubled what we used to have before the implementation. It makes our services more reliable. We have also had more uptime of our operational applications. View full review »

Stability is great. We keep all of our stuff up to patch and keep up on drivers. I actually couldn't tell you the last time I've had one of them crash on me. It's been a while. View full review »

VP of Product Engineering at Navisite
vSphere has been very stable. It would be where it is in the market overall if there were any sense of instability. No software nor hardware is perfect, so really it comes down to the failure rate that we see running workloads on vSphere. Is it significantly, materially, measurably different than running those workloads on bare metal? I would say absolutely not. Equally important is the stability better because, when things happen, hardware is lost. In response, VMware HA automatically restarts those workloads and the effective downtime is radically minimized. This is compared to what it would be for a human response. View full review »

Kevin Williams
IT Analyst I at Sacramento City College
The downtime that we have experienced has not been that much, and normally it's the result of a mistake on our part, not necessarily the software. We've misconfigured something or we haven't thought about a configuration setting that we should have put in place or we didn't do our research. It's not normally the software that has a problem. When we do have a software glitch, it is normally a reboot and it's back up and running, so we have not had much downtime. View full review »

Senior Systems Administrator at a transportation company with 1,001-5,000 employees
Stability has always been really well done with VMware. I have always been very happy with the stability of the system. You can set it up, you can check your optimizations there. But as far as weird issues with being able to convert things from physical to virtual, I've really had no big problems in switching that over. It's been really seamless to the end-user as well, just doing standardized conversions. It's been very stable and easy to manage. I haven't had any loss of data in quite some time. Data is the key to everything. Downtime and loss of data are almost unacceptable in my current position. View full review »

Eric Garrison
Customer Engineer at ATTO Technology
It's very, very stable. The amount of times that we have to reboot vCenter or any of the VMs is very rare. It's only gotten better over the last couple of years. You expect a certain number of reboots and it just seems that the number needed is going down every single year. View full review »
Network Administrator with 5,001-10,000 employees
The stability is pretty good. If there is a stability issue it's probably something else, for instance, the power for the building or something like that. It's usually not an issue with VMware. View full review »
Infrastructure with 5,001-10,000 employees
The EXSi hosts are rock solid. We've had a couple problems once or twice with a driver update or bad firmware on one of the devices, but I haven't actually had a problem with those in years now. They pretty much run rock solid, 24 hours a day. vSphere itself is great when you don't need to make updates, but any time you have to touch it, unfortunately there is always a little bit of a fight to get it to do what you want. But then, once you get it there, it's great. View full review »

I haven't had any real issues. In the very beginning, there were some issues when upgrading or migrating from versions. However, our last upgrade was 5.5 to 6.5 where went from Windows to the Linux OVF version, and we did not have any issues with it. View full review »
Raden Evangelista
Systems Engineerineering Manager at a wholesaler/distributor with 51-200 employees
We take whatever the customer has and make sure we use our application to upgrade them. If there is anything unexpected, we already know internally instead of doing it during production or go live. It is bad for business to extend planned downtime more than expected. View full review »

It's very stable. We had one "pink screen," which is basically equivalent to the "blue screen" in Windows, and that was hardware-related. View full review »
Brian Kirsch
Instructor at MATC
Stability has been good since the 6.0 days. The biggest issue with stability is the SSO. That is still an issue as far as integrating it with Active Directory, and any large scale of it. That is still a work in progress. However, the core stability aspect of it has been there and hasn't changed. This has just gotten better. View full review »
Ayodeji Ariyo
Senior Network Engineer with 1,001-5,000 employees
The stability is okay. For the most part, when we have issues it's because the self-connections or the VPN connections between the cloud space and our internal network go down. It doesn't necessarily mean that access to those applications is cut off from the outside, because the applications are up. It's just the connectivity on the inside. Depending on the use case, if the application is hosted on the outside and it's being used by people on the inside - which in most cases is not the case - it's usually people who manage it who can't get to it. For the most part, we're okay with it. View full review »

Tony Reeves
Network Administrator
The stability in our vSphere environment has gone very well. We have never actually had an outage. Due to the HA failover capabilities of the cluster, the High Availability of vSAN, Distributed Resource Scheduler allowing you to basically vMotion VMs and balance your loads across all your clusters, it's been very highly available. We've never had an outage or an issue; never any kind of a data loss incident, even when we were running external storage as well. View full review »

IT Analyst at a manufacturing company with 10,001+ employees
Maybe 80 percent of the time, our issues were hardware problems caused by HPE. Crappy driver issues leading to a blue screen of death. If you have a corrupt driver, is it the fault of the VMware or is it the fault of the vendor who should support it? These were mostly our outages. This was due to the product cycles being too quick. Neither VMware nor HPE could test the stuff properly. The cycles were too quick and they had to push out the software, then errors happened. Both software companies needed to fix or address issues in their old versions, but then they also implemented new bugs in their newer versions. Software will never be error-free, because the product cycle frequency is too high. We are version 6.0, but these issues happened on 5.0, 5.1, and 5.5. We haven't seen them on the current version. It is annoying because we work with clusters, and we can't really have one node fail. View full review »

Sean Crawford
Information Systems Analyst at Sandag
Stability for vSphere 6.7 has been a little rocky at times compared to 6.5, but I believe that's because it's a very new product. With updates later, I think it will stabilize out. We have especially had an issue with our backup software communicating with vSphere 6.7, but that's been remediated so that has kind of gone away. Initially, it was a little rough, but now it's smoothing out. View full review »

Stephen Krujelskis
Senior System Administrator at a university with 501-1,000 employees
I find the stability of vSphere to be pretty great. We've had some issues, like everybody. Most of them were around hardware, so we thought it was really important to check the compatibility lists and make sure that you're running the right driver versions. But once you've got that running, it's solid. We don't have any stability problems. View full review »

The stability of vSphere has reached a good point. Especially without the Flash and the so-called FLEX Client, with HTML 5 it is much more stable than it was before. Previously we used vCenter on Windows. We're adopting the vCSA now, it's much faster and more stable. View full review »

Tom Pine

We don't have any downtime, because I built it right. I work a lot with VMware's engineers. Though, it is not stable. The product was pushed out too quick, and now, there are a lot of bugs. We have seen bugs in vSphere, NSX, and ADDVOLUME, which we haven't even been able to have installed yet because of bugs. Also, with Horizon, we are constantly running into problems. We are a bleeding edge company. We push it. Yet, we're not even touching 6.7 because it's too buggy. View full review »
