Network Engineer at a retailer with 51-200 employees
VMware contributes a lot to virtualization with its better security and load management techniques.
What is most valuable?
• VMware Server is problem solving and cost saving.
• No need to buy hardware for every server required, just purchase one server and run multiple virtual machines on that single hardware.
• Offers testing solutions, provisioning solutions, and makes testing and rolling out installation easier.
• Easy to use technology and industry leader in virtualization technology.
What needs improvement?
• The new Graphic User Interface is not of high quality.
• Web based User Interface means breaching compatibility with any principle of rich client applications, and means lots of bugs particular to every different browser
What other advice do I have?
A major issue with this server is that there are several free solutions offered. These are very appealing because of the virtualization rollout that cuts costs. If your intention is to decrease costs by using the VMware Server instead of several machines for several servers, the horsepower of the VMware hardware should be very powerful or every virtual machine will experience a mess.

Free Hypervisor from VMWare
Valuable Features:
ESXi has one major benefit that outweighs the others; IT'S FREE!Yes, it has plenty of other benefits, like running a wide variety of different virtual operating systems in virtual machines (it supports every platform but OS X, and that can technically still be "hacked" onto it).It's incredibly robust, has excellent resource management, and is easy to set up. It allows for importing of virtual appliances, or pre-made VM's, or a creation of your own VM's.
Room for Improvement:
The only issue I have with ESXi is that it is console (CLI) based. While I personally have no operational issue with this, as most of my training began with CLI based systems, some people might not want to configure a high availability virtual machine server via the Command Line.They're now marketing ESXi as VMware vSphere Hypervisor, which makes sense because that's essentially what it is. There used to be another product called ESX, which was a step between ESXi and vSphere, but they did away with that and rolled some of the features into ESXi.
Other Advice:
All in all, it is an excellent solution that I have deployed in multiple locations and organizations.

Excellent tool for its time, but there are better solutions now.
Valuable Features:
VMWare server is an excellent virtualzation tool for the workstation. It could be used as a limited functionality version of VMWare Workstation or as a host for your virtual machines, with all of the bells and whistles that came with Workstation, such as:- Centralized Management of Virtual Machines.
- Remote management of VM's and configurations.
- Integration with VMware Player and Workstation, to view the machines hosted by Server.
Room for Improvement:
Unfortunately, this software has reached its End-Of-Life, and has held that status for almost two years. Meaning, there are no new software updates or available downloads for it. This product has basically been replaced by ESX, ESXi and vSphere, which are functionally less resource intensive because of their design. We used this tool during my Linux classes when I was attending College for my B.A.
Other Advice:
As of now, OracleVM (formerly known as VirtualBox), is an excellent solution that is open-source and freely available for download.

Vmware ESXi - innovation, changing the old traditional ways
Valuable Features:
1) Easier way of segmenting the resources.
2) Host profiles - Template to build hosts in minutes.
3) Performance and Graphs - Easy to monitor the hosts
4) Vmotion - In essence, this technique helps you to move a live server between hosts without any downtime.
5) Robust Management Tools
6) Cost saving
7) Advanced memory management - The memory unused in the hosts can be reclaimed and used effectively.
8) High availability
Room for Improvement:
The major disadvantage that i can think off is that we have to pay for all the features to be available. Virtualization has made datacentre operations easier. As a sysadmin, managing multiple hosts is more simpler and flexible with the vmware ESXi. Running multiple hosts, operating systems on a single host makes it more efficient and saves costs. ESXi also allows you to pool the resources of several machines effectively, thereby helping to run the application smoothly without hassles.
Other Advice:
This gives the technology lovers an opportunity to do all the things they want or need to do at the same time.

VMware ESXi allows for excellent management of host resources such as memory and CPU processing time.
Senior Manager of Data Center at a integrator with 51-200 employees
VMware Server is the best available virtualization solution with live migration, high availability, and dynamic resources
Valuable Features:
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
Room for Improvement:
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
Other Advice:
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.

@kapilmalik1983, have you done some storage performance profiling to see what sort of load those 10 VMs require or currently use today? vCenter or the ESXi client can help you get the numbers as a group, but get them from within the VMs too. Perfmon would be the easiest way to do this. Set up disk statistic collection for each of those VMs on a one minute rotating period, cycle the log file nightly, and get a week's worth of collection stats. Analyze the output and see en mass what sort of performance levels you need (via MB/s and IOPs requirements). From there, we can help select a disk vendor that could fit the requirements. Other things apply, such as if you have a solid storage IP-based or fiber based network already in the environment, etc.

Easy to install and configure, but lacks central management
Valuable Features:
- Free
- Easy to install and configure
- Very low overhead
- Great management features
- Enterprise Ready
Room for Improvement:
- Free version limits server memory to 32GB
- No central management of other ESXi servers, each one needs to be logged-in individually if you have multiple servers.My experience with VMware EXSi is that it's the fastest Virtualization platform out there. This is basically because of the very good architectural design of the underlying hypervisor, which consumes a very small amount of resource overhead and provides a rich set of features that are enterprise grade. The free version really has a great feature set plus a management software that you can use to manage individual server instances.
Other Advice:
The downside to the free version is that you can only use it on a server with a maximum of 32GB memory. Also, you cannot manage multiple ESXi instances with the management client. You have to log-in individually to each server running the free version of EXSi. These limitations are surely a setback considering other competing products do not have these limitations and even offer features which are only available in paid versions of VMware.
