BLADEOS 6.5.2 Application Guide
166 Chapter 13: VMready BMD00220, October 2010
VE Capacity
When VMready is enabled, the switch will automatically discover VEs that reside in hypervisors
directly connected on the switch ports. BLADEOS 6.5 supports up to 2048 VEs. Once this limit is
reached, the switch will reject additional VEs.
Note – In rare situations, the switch may reject new VEs prior to reaching the supported limit. This
can occur when the internal hash corresponding to the new VE is already in use. If this occurs,
change the MAC address of the VE and retry the operation. The MAC address can usually be
changed from the virtualization management server console (such as the VMware Virtual Center).
Defining Server Ports
Before you configure VMready features, you must first define whether ports are connected to
servers or are used as uplink ports. Use the following ISCLI configuration command to define a port
as a server port:
Ports that are not defined as server ports are automatically considered uplink ports.
VM Group Types
VEs, as well as switch server ports, switch uplink ports, static trunks and LACP trunks, can be
placed into VM groups on the switch to define virtual communication boundaries. Elements in a
given VM group are permitted to communicate with each other, while those in different groups are
not. The elements within a VM group automatically share certain group-level settings.
BLADEOS 6.5 supports up to 32 VM groups. There are two different types:
Local VM groups are maintained locally on the switch. Their configuration is not synchronized
with hypervisors. Of the 2048 VEs supported on the switch, up to 500 VEs may be used in local
groups.
Distributed VM groups are automatically synchronized with a virtualization management server
(see “Assigning a vCenter” on page 172).
Each VM group type is covered in detail in the following sections.
Note – VM groups are not supported simultaneously on the same ports as vNICs (see “Virtual
NICs” on page 153).
