VMware vSphere Reviews

The best part of ESXi for us is the flexibility it gives us, we can spin up a new server in minutes, we can increase VM drive space live, we can perform maintenance on our infrastructure with minimal down time – we have a blade solution, and have the capacity to move VM’s to allow us to perform updates/upgrades to individual hosts during work hours with zero disruption to the business.

Its allowed us to reduce the time needed to bring onboard new services. For example, we migrated from Exchange 2003 to Exchange 2010, the flexibility of running a virtualised environment allowed us to quickly build new servers to test, this is something that would have taken considerably longer using physical hardware, with VMware, we were able to tailor the system spec without having to scramble around for memory, drives CPU’s etc. This ultimately reduced the time to complete the migration.

I’m keenly awaiting multi core Fault Tolerance, so I can have all our VM’s covered by FT – currently it’s only available for single core VM’s.

Fault Tolerance is now available for multicore VM's, but, you;ll need to factor in how many cores the host has before rolling this out to the more powerfully specced VM's.

None, we found VMware support really good.

None, we had a few teething issues which were mainly due to our lack of knowledge of the product when we first installed it.

None at all, we can add hosts on the fly, we’ve expanded our SAN array from 1 to 3 shelfs without issue.

Customer Service:

We use VM and also a 3rd party for support – no problems have been encountered which were not resolvable.

Technical Support:

1st class – no complaints at all.

We had the implantation done via a reseller, what we did find was that the initial knowledge transfer of skills from the vendor to us was questionable (in that they came in and set it up, then really left us to it. This gave us a very steep learning curve at the outset.) If we did the project again, this is an area that I would focus on as part of the project, so that we were more comfortable with what we put in place. This doesn’t mean we had a negative experience, rather we were a little green to start with.

I’d say, understand what it is you wish to achieve from the outset. Take into account growth, be aware of VM sprawl and the associated license costs – we were all happy to add servers left right and centre, we’ve now been through a server rationalisation process to bring our VM server count down a little. Make sure that your engineers are suitably trained and make sure that you have a good support contract in place – it gives you peace of mind!

From the admin perspective, the centralized management/administration of the environment. Additionally, a much smaller data center footprint, streamlined machine deployments and flexible resource sharing rank right up there.

It is hugely more efficient for daily monitoring, patching and upgrades and deploying new machines. With more than 100 servers we would have a couple of full time folks just for patching! Server reboots during business hours are far less disruptive to the end users. We are also in the midst of a large e-commerce project and vSphere has allowed us a ton of flexibility with development and test environments that we wouldn’t have in a physical environment. A lab environment that very closely mirrors production was far easier to design and build than the physical lab we had been struggling with for years.

We are a small shop but still pay the big bucks for licensing vSphere products in order to gain the features that fit our goals.

I'm looking forward to a review of VMTools updates in vSphere 6, which have hopefully been revamped. We currently have a somewhat dated change process so tools updates are hampered by a process that doesn't quite fit and requires more after hours work that is necessary.

We implemented vSphere 4.1 in October 2010 and upgraded to 5.1 in June 2013, then to 5.5 in June 2014. We are beginning to review vSphere 6. Alongside vSphere, we also use ESXi 5.5.0.2718055, and vCenter 5.5.0.2646482.

No – the original deployment went very smoothly with vendor assistance. Upgrades since have been smooth as well. We did a lot of homework before embarking on any upgrades.

No. The virtual environment has remained incredibly stable over the five years since the original deployment.

No. The original deployment consisted of virtualizing 32 machines. We now have over 100 VM’s.

Customer Service:

We periodically have regional reps reach out but they don’t seem to know much about our environment. When we call in, for whatever reason, the folks answering phones are very polite, respectful and efficient at directing our calls.

Technical Support:

Periodically we have an issue where we have to call in to tech support, but many times are able to Google the issue and find an answer on VMware’s site. When we do have to call though, tech support has been great to us. They definitely stick with an issue until we say it’s resolved.

No, we moved from a completely physical environment.

A little of both. It was complex because we didn’t know a lot about it but being involved in the setup with a vendor proved itself to be pretty straightforward.

We implemented with a CDW team since we hadn’t done any virtualization. They were extremely knowledgeable regarding not only VMware but Cisco, Microsoft and Linux which helped us design an infrastructure that suited our needs well at the time.

We had one Citrix server at the time and I believe we did a very high level evaluation of Xenserver, but VMware was more in line with our virtualization goals.

Do your homework so you learn as much as you can about virtualization concepts as there are many nuances that are quite different from the physical counterparts. It’s easy to get an ESXi host stood up and install a vCenter management server – then you decide to stand up a “few” VM’s and when you figure out how easy that is, you are off and running. But what about your network configuration and HA or DRS to name a few. It’s way easier to learn the concepts ahead of time than to have to research a bunch of little issues after the fact. Google VMware and/or vSphere and have at it!

• vMotion
• High Availability
• Storage vMotion
• DRS

We have v5.5 in production, and v6 in test.

As we are resellers of VMware, we will be migrating customers to v6 in the future. This is to keep in line with new features and better performance in new versions

I would like to have the old vSphere client back as it is a great client to use. Sometimes the web GUI can be a bit clunky along with the newer client.

I used it for two months in a test scenario.

It was fine.

No issues encountered.

No issues encountered.

Technical support with VMware is very good. Once they have the logs from your system they will come back with a solution fast.

We used a previous version of VMware.

We've only deployed v6 in a lab environment, but it was easy to deploy, and there was no major differences to v5.5

We did it in-house.

None as of yet but hopefully we will see one.

No other products were evaluated.

I would advise you to implement it as I believe it's still the best in virtualization for expandability and usability.

We have the ability to run within our block environment with a private cloud capability, enabling us to realize our automation roadmap.

We’ve consolidated over $10 million for licenses, $12.2 million in maintenance, and $10.3 million in labor costs – it's a tremendous cost-saving.

I would like to see non-cloud native apps to be able to run on infrastructure and not be dependent on the underlying VMs for stability.

It improves our stability.

We can dynamically scale within hours to meet our business demand, which use to take months.

We include a mission-critical support model, which gives us a very rapid response. So the response time is very good.

Very complex, as there are a lot of moving parts to get into service. We simplify it for the end users but it is complex.

I would say that the total cost of benefits are not just across virtualization but across general business categories. Don’t cut yourself short from using the solution to drive cost-benefits in multiple financial categories.

• vCenter
• ESXi Host
• Configuring
• Management
• Patch
• Maintenance

It has reduced the space, and power utilization, as well as allowing a much more efficient way to increase/decrease the server inventory.

I think VMware should make it easier to manage different components (ESXi Hosts, vCenter, etc.) through firewalls. Some organizations have to separate the components with firewalls for security purposes, and VMware does not act well when hosts are separated from vCenter by firewalls.

I've used it for two years.

Absolutely, numerous issues in particular HP ESXi VMware images that we utilized created a number of deployment issues. ESXi Hosts would lock up, network configs would malfunction and plenty more. We had issues deploying vCenter on windows 2012, and Windows 2012 r2, such as being unable to successfully integrate vCenter with Active Directory and plenty more.

Technical support was difficult to obtain at time because of the limited number of resources allocated to our program.

The previous solution were individual physical servers, which we replaced by utilizing VMware.

It was straightforward, and physical servers used to host web applications.

We implemented it in-house.

No other options were looked at.

Pros on the VMware Server are- 1) Centralized management and configuration 2) Remote management and headless operation available 3) VMotion feature helps in real time movement of virtual machines from one server to the other 4) Automated scanning and patching of hosts 5) VSphere DRS for continuous monitoring resource pool utilization 6) Can be integrated with Windows Server Active Directory 7) Easy to use high availability and fail over clustering

Few cons of VMware Server are 1) It is available for free so bug resolution and patch management takes time 2) Poor memory management 3) Requirement for supported SCSI and SATA controllers

One of the cutting edge virtualization technologies offered by VMware works on platforms like Windows, Linux, and Solaris. It facilitates an application developer to test applications on virtual machines with ease of configuration and management. It provides visibility at each and every level of virtual infrastructure.

Virtualization, VDI and application publishing are the most valuable features of VMware vSphere.

The solution’s pricing is too high and could be improved.

I have been working with VMware vSphere for more than five years.

VMware vSphere is a very stable solution.

VMware vSphere is a scalable solution.

The solution's technical support team is good because if we open a priority ticket, they call within 30 minutes.

Positive

The solution’s initial setup is easy.

VMware vSphere can be installed in just two days for a normal project. However, it would take at least three months to implement everything, depending on the scope of the customer's requirements.

The solution’s licensing terms keep changing, which is too complex for our customers. If a user purchases a new license, it cannot be mixed with the existing perpetual license.

Overall, I rate VMware vSphere an eight out of ten.

We are using VMware vSphere to manage the virtual environment. We use it for visibility and for managing the host.

What I want to see, I can get easily from VMware vSphere, because I know how to navigate it, as I've been using it for years. I also don't have issues with its operation, stability, and security. I also find the VMware support team diligent when they assisted me with the issues I raised.

Before the latest versions of this software, we used to work with versions 5.5 and below. We used VMware vSphere as a client, as an application, e.g. it was not web-based. Now that has changed, because they've moved it from the application to the web-based version. It's the only change I've seen which I found very difficult because it was challenging to connect to the web, particularly because it can be very slow. It freezes, unlike the app version which was absolutely perfect.

The performance was better with VMware vSphere as an app, but not with the web-based client. The web-based client could be improved, in terms of its speed. It could be faster, but I also just learned that since everything is moving to cloud, there's a reason why there's a web-based client now.

I have been using VMware vSphere for almost 10 years.

I don't have any problems with the stability and security of VMware vSphere.

I had to engage with the VMware technical support team once or twice last year because we had a disaster, and they were able to assist me diligently.

The installation for VMware vSphere was a one-time installation. You do it once,  and that's it.

I had a consultant do the VMware vSphere installation for me.

We pay for the license of VMware vSphere yearly.

We are using VMware solutions. We are running the VMware standard edition. We also have VMware vSphere and VMware ESXi.

We are running the latest version of VMware vSphere: 7.0. We started with version four of this software.

I wouldn't say that there are features that I like the most about VMware vSphere, because it's just a normal management console. It's a default client management software for the virtual environment. It's just a console that we use.

We have been using the software since we enrolled into the virtual CRR, so we are used to it. I can't say whether it's easy to use or not, because I've been using it forever. I can't do any comparison. To say it's easy to use or it's not easy to use would not suffice, because I've been using it for years, so I know how to navigate the platform. What I want to see, I can get easily from VMware vSphere.

I don't recall the last time we installed the software, and even if it was a difficult process, I wouldn't know, because that would best be answered by the technical team, who keeps installing it for different lines. For me it was something that was done once.

We only have one engineer who takes care of the deployment and maintenance of VMware vSphere. The software is only used by fewer than five people, e.g. just the administrators. We're not increasing the number of users, because there are only just a few people needed to man the environment.

I would recommend VMware vSphere to others, particularly because when I contacted them about some issues, they assisted me diligently.

From one to ten, I'm rating VMware vSphere an eight.

When you talk about performance improvement of VMware vSphere, you have to look at other factors. You look at the whole infrastructure. You can't look at the software alone, because when it comes to performance, you also have to look at your hardware. You have to look at your storage. It isn't just the software, e.g. VMware vSphere, that you are using. For example, the last time we had an issue, it wasn't only because of the VMware side. It was also because of our storage, e.g. Our storage capacity was full, so we had to engage VMware. To improve performance, the VMware infrastructure as a whole should be improved, which means changing the storage, storage accessories, etc. VMware vSphere is only connected, and it's only a software that is running on the hardware, so to improve performance, we also need to talk about and look into the hardware aspects of the solution.
