Note: For all VMware VI3 Infrastructure editions (Enterprise, Standard, and
Foundation), two Socket licenses must be purchased with a corresponding
subscription and support for the VI3 Edition purchased. The licenses are also
valid for use with ESXi Installable Edition. VMware ESXi is now available free
of cost, with no subscription required, however additional VI3 features are
licensed separately.
VMware Infrastructure ESXi Edition
This edition has no restrictions on shared storage connectivity, memory
utilization, or number of CPUs of the physical server. However, if you
purchase IBM x3850 M2 with VMware ESXi integrated hypervisor and
subsequently require additional functionality, you can upgrade ESXi to the VI
Enterprise, Standard, or Foundation Editions. See "License upgrades from
ESXi to VI3 Editions" on page 25 for details about upgrade options.
The System x3850 M2 and x3950 M2 servers are designed for balanced system
performance, and are therefore uniquely positioned to take advantage of the
larger workloads now available to be virtualized.
Table 1-7 shows the limitations of each VMware distribution that is supported on
the x3850 M2 and x3950 M2 (single node).
