Before we talk about
Vmware Accelerator Kits, lets try to understand little bit of Virtualization
basics for Datacenter Virtualization. To virtualize your Datacenter or migrate
from physical to Virtual only two Vmware products are sufficient, i.e.,
- Bare-Metal Hypervisor (vSphere ESXi)
- Management Software (vCenter Server)
With vSphere ESXi,
you virtualize and run multiple VMs on it and with vCenter Server you manage
all the ESXi hosts and VMs and with vCenter Server comes all the distributive
services like vMotion, Storage vMotion, HA, DRS etc. This two products are the
base of Vmware virtualization, after this when you add any new Vmware product
like View, SRM, vCloud Director or any other product has to communicate and
rely on these two products (ESXi and vCenter Server).
It is very important
to first identify the functional requirements of virtualization for the
respective environment and then decide on which Vmware products to chose
keeping future growth or implementations in mind. For example, if your
datacenter has 100 physical server (running production and development
applications) then you may virtualize your datacenter and enjoy the benefits of
virtualization. By server consolidation you save on power, cooling, management,
space etc but along with this there are lots of considerations like which minimum
features are required at the hypervisor level to meet your SLAs or application
requirements without compromising on performance.
vSphere ESXi comes
in 3 Editions (Standard, Enterprise and Enterprise Plus), apart from pricing
they basically differ in some advanced features. You need to understand whether those advanced
features are required or not depending on your environment, otherwise the
Standard edition is sufficient for small to medium size environments. vCenter Server comes in 2 editions, Foundation and Standard. Foundation can manage upto 3 ESXi hosts.
Below
table lists the features which comes with Standard Edition of ESXi
In Enterprise
Edition below additional features are added on top of all the Standard features
Enterprise Plus is
the highest edition with all the features
After understanding the importance of these features, you may choose the most suitable
license for your environment. If all the application requirements can be fulfilled
with Enterprise edition then it doesn't
make sense to opt for Standard to save on some licensing cost. The other
consideration for this licensing would also depend on the future growth or if
you are planning to add other Vmware products. As the other Vmware products
uses some advanced features of ESXi for better efficiency. For example, vCloud
Director requires Distributed Switch to utilize all the networking features.
