More, smaller hardware systems
|
-
Smaller hardware systems generally cost less.
-
More, smaller hardware systems can be deployed across many locations
to support a distributed business environment.
-
More, smaller hardware systems can mean less down time for system
maintenance, upgrade, and migration because traffic can be routed to other servers
that are still online while others are being maintained.
|
-
Smaller hardware systems have a more limited capacity, so more of
them are needed. Management, administration, and maintenance costs go up as the number
of hardware systems goes up.
-
More, smaller hardware systems require more system maintenance because
there are more of them to maintain.
|
Fewer, larger hardware systems
|
-
Fewer hardware systems means fewer fixed management costs per server.
If your management costs are a recurring monthly bill, whether internal or from an
ISP, costs will be lower, because you have fewer hardware systems to manage.
-
Fewer hardware systems can also mean easier system maintenance, upgrade,
and migration because there are fewer systems to maintain.
|
-
Larger hardware systems generally cost more initially.
-
Fewer hardware systems can also mean a greater system down-time for
maintenance, upgrade and migration.
