When an I/Port or a Blade is selected, its information is shown at the bottom of the
screen, as shown in Figure 30.
When to Switch and When to Spare
When an administrator needs to move a user from one Blade to another, the decision
should be made with both the administrator’s and the user’s needs in mind.
First, why is the user being switched? If the switch is being made to perform a brief
maintenance task such as exchanging a Blade, the administrator typically has ample
time to select a Blade to which the user can be switched. On the other hand, if the user’s
Blade has failed, sparing them over gets them back online in the shortest possible time.
Next, what are the user’s computing demands? If the user is a “power user” who
needs a lot of power and is in a Dedicated allocation, moving the user to a spare
Blade may be the best choice. Since spare Blades typically are unused, this would
provide the largest amount of available computing power for the user. Switching a
“power user” to a shared Blade already occupied by three other users would probably
result in noticeably degraded performance for all four users.
On the other hand, if the user has only modest needs and is in a Shared group,
switching them to another Blade within the same group is the best option, and is
likeliest to be the least visible to the user. If the user ends their RDP session, on
re-establishing a connection they will rejoin their assigned group according to the
least-used selection method. But if network security policies are in place, switching
them to a different Shared Blade group may leave them without access to their
networked files or applications.
