Overview of Shared PERC 8 Card

Configuration

This document helps you upgrade the Dell PowerEdge VRTX system from a single controller

configuration to a fault tolerant Shared PowerEdge RAID Controller (PERC) 8 configuration. The entire

procedure may take you up to six hours.

The following are the two types of controller configurations:

• Single Shared PERC 8 card configuration — In this configuration, the PowerEdge VRTX system is

installed with a single Shared PERC 8 card.

• Fault tolerant Shared PERC 8 card configuration — In this configuration, the PowerEdge VRTX

system is installed with two Shared PERC 8 cards. Either of the two Shared PERC 8 cards can access

the storage subsystem. If one Shared PERC 8 card fails, the other Shared PERC 8 card takes control in

a seamless transition.

Safety Information

WARNING: Whenever you need to lift the system, get others to assist you. To avoid injury, do not

attempt to lift the system by yourself.

WARNING: Exercise care when removing or installing components when the system is on, to

avoid the risk of electric shock. For electrostatic discharge (ESD) compliance, see dell.com/

regulatory_compliance.

CAUTION: Many repairs may only be done by a certified service technician. You should only

perform troubleshooting and simple repairs as authorized in your product documentation, or as

directed by the online or telephone service and support team. Damage due to servicing that is

not authorized by Dell is not covered by your warranty. Read and follow the safety instructions

that came with the product.

CAUTION: Do not use excessive force in either removing or reinstalling components.

CAUTION: To maintain optimum thermal conditions, ensure that there are no obstructions to

airflow on the front and back of the enclosure. The front and back of the enclosure must have at

least 30 cm (12 inches) and 61 cm (24 inches) of unobstructed space respectively.

NOTE: To ensure proper operation and cooling, all bays in the enclosure must be populated at all

times with either a module or with a blank.
