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.
