VMware vSphere Review

vSphere Review

Valuable Features:

- Enterprise class solution - Live Migration (both server and storage) - High Availability and Load Balancing - Disaster Recovery - Lots of 3rd party vendor support - Excellent technical support

Room for Improvement:

- Cost - Lack of support for virtualization (all hypervisors) - Licensing- Started with VMware ESX ver 2.1 in 2004. Currently using vSphere 4.1i and working on upgrade to 5.1 - Chose VMware for several reasons (1) Had experience with Desktop and GSX products (2) Ran on bare metal (3) No other real competitors at the time

Other Advice:

Advice: - VMware is not the only game in town anymore - Look at your requirements: - If you are a small to medium shop other server virtualization products may provide what you need - If you are a large shop I would recommendVMware

Disclosure: I am a real user, and this review is based on my own experience and opinions.

Nice write up on Pros and Cons. Did you face any challenges in upgrading to vSphere 5.1?

When you say a con is lack of virtualization (all hypervisors), can you elaborate?
I have multiple hypervisors running nested on my VMware vSphere environment (works better with 5.5).
Otoh, if you are referring to being able to manage other hypervisors with native vSphere (e.g. client), then fair point as you would have to add the multi hypervisor manager download part of vCenter to be able to do that.
However as you say, many options, Hyper-V is often overlooked or perceived to be expensive as from Microsoft which is not always the case. Likewise there is Xen and KVM among others. From a management perspective you can also do things such as layer OpenStack compute over different hypervisors (e.g. Hyper-V, vSphere/ESXi, KVM, etc). Hence explore your options.
