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 mean a greater system down-time
for maintenance, upgrade and migration.
