Chassis

The PowerEdge 1550 is a 1U system. The term "U" is a unit of measure
in rack mountable components. A U is 1.75". This unit of measure
describes the height of a product and therefore the Dell PowerEdge 1550
is 1.75 inches high.
At 1U the PowerEdge 1550 is half the height of a PowerEdge 2450. More
PowerEdge 1550 systems can fit into a rack than PowerEdge 2450
systems.

Dell Open Manage Array Manager

Dell OpenManage Array Manager is a user interface for installing and
managing RAID storage environments that are independent of an
underlying hardware RAID controller.
This gives users a consistent look and feel regardless of the actual RAID
controller being used.
Over time, Array Manager will be integrated with all of Dell storage products:
The earliest releases focused on host-based RAID controllers only.
Subsequent releases have added external RAID systems and validation
with Dell SAN configurations.
Future releases will include interoperability with an integrated product
strategy for Dell SAN Management.
Array Manager hides the differences between these tools by unifying them
through a consistent look and feel. This is accomplished by providing
users with a single GUI, built on a common API through which each
vendor's RAID or host bus adapter is accessed.
