Improvements to My Organization:
Thanks to vSphere we have improved our availability and scalability, and we are now able to dynamically move to a cloud paradigm. vSphere for us, is not a simple computer virtualization; it provides a complete infrastructure which combines computer storage, and networking elements in a single software layer, that we are calling SDDC.
Previously, we thought it was a simple server consolidation, where bulk and power consumption were drastically reduced. Now we are moving to a software-defined storage and software-defined networking to keep control of all IT environment, from service to a single infrastructure components.
We hope to keep all the physical datacenter elements under the same software layer, and we are hoping that that dream will comes true in the next years.
Room for Improvement:
The introduction of a web console could be a great improvement for sysadmin, but the poor responsive interface has been solved in v6.0. The previous sysadmin/design experience with vSphere client could become a dangerous loop for its development.
At the moment, VMware admins say that the vSphere client will never die!
The vSphere installation, and operations are fully documented. I think that VMWare spent a lot of time writing documents which could be useful during the platforms lifecycle.
Before installing this product, try to design all the components, and
don't be shy asking for comparisons or sharing your experience. Often
design guidelines are the result of customer implementations, and
different points of view. Before bringing it into production in your
environment, execute hardening procedures.
If you are working for an ISP, where network admin rules an IT
organization, try to get control of all networking devices connected to
all services provided by your platform. Often, ISP network
administrators are specialized in internet networking, and often they
don't know data center networking issues and design impacts.
One of the
worst savings to do when trying to consolidate, is to use less
networking devices; for this reason I suggest you never play around with
them when you need to use eight interfaces per host. If you need them there is no reason to have less than you have asked.
Which version of this solution are you currently using?
