Figure 3 VCEM architecture overview
Using VCEM, system administrators can quickly deploy, replace and recover servers and their
associated workloads by assigning or reassigning the VC server connection profile to an enclosure
bay. The example in
illustrates a server profile movement operation from “Server
A” to “Server C” using VCEM.
NOTE:
The LANs associated with each uplink port and the attributes of the VC server profile
remain exactly the same; only the location of the server profile has changed.
When a VC server connection profile is moved, the associated MAC, WWN, boot from SAN
parameters, and related workload always move with the server profile.
From the VCEM GUI, server profiles can be moved to a user-defined spare server. A server profile
can be moved manually from one VC Domain to any other VC Domain in the same VC Domain
Group, or to a different VC Domain Group, whether it is in the same rack, across the datacenter,
or at another location. A server profile move can be scripted within the same VC Domain only,
using the profile failover capability. The profile movement and failover functionality provided by
VCEM can be used to provide cost-effective server blade recovery, perform proactive hardware
maintenance with reduced downtimes, and control rapid server repurposing to meet changing
workload and application priorities. When moving VC server profiles, the fastest completion times
are achieved when the corresponding source and target servers are configured to boot-from-SAN.
The automated profile failover functionality delivered in VCEM requires a boot-from-SAN
environment.
