NEW-GENERATION SERVER TECHNOLOGYIf Dell OpenManage software agents are installed on the serverblade OS, the event will also be handed off to OMSA for user notification.OMSA can be configured to send SNMP traps and SMTPe-mail alerts to multiple recipients.The combination of the DRAC/MC, the server blade’s BMC,and Dell OpenManage agents is designed to provide a redundantnotification path and redundant logging. The DRAC/MCcan send an SNMP trap, an SMTP e-mail alert, or both throughits own network connection; at the same time, Dell OpenManageagents can send an SNMP trap and an SMTP e-mail alert throughthe server blade’s network connection. The event is logged in boththe DRAC/MC SEL and the BMC hardware log.In addition, Dell OpenManage agents can provide enhancedlogging capabilities in the OMSA Alert log and Command log—thesame level of logging providedby Dell OpenManage agents onstand-alone Dell servers.The DRAC/MC also monitorsthe presence and health ofthe I/O modules, cooling modules,KVM switch module, andpower supply modules in thechassis. When an event occurson one of these modules, theDRAC/MC handles the eventexactly as it would handle anevent on a server blade. Theevent is written to the DRAC/MC SEL and—if configured—an SNMPtrap, SMTP e-mail alert, or both are sent over the DRAC/MC outof-bandnetwork.The PowerEdge 1855 blade server can also be remotely monitoredand managed with Dell OpenManage IT Assistant (ITA), whichis included in the Dell OpenManage suite. When ITA discovers thePowerEdge 1855 system, it groups PowerEdge server blades, DellPowerConnect switches, and the DRAC/MC into a Chassis group—providing an overall system view that allows administrators to surveythe individual server blades and components.Access to the logs from the DRAC/MC and the server bladesis available from the ITA console. When OMSA is installed on theserver blades, OMSA can be configured to send server blade–relatedSNMP traps to the ITA console. Additionally, the DRAC/MC andPowerConnect switches can be configured to send SNMP traps tothe ITA console. ITA can decode and report the traps and updatethe component and system status accordingly on the Status pageof the system view.When an organization hasmany servers to deploy, orwhen physical access islimited, administrators canopt to configure and deployserver blades remotely.PowerEdge 1855 blade server change managementKeeping server blade drivers, firmware, and BIOS updatedcan be challenging in organizations that have many servers toupdate. Using Dell Update Packages, administrators can updatethese components one at a time, or simultaneously apply theupdates to many servers using management frameworks such asMicrosoft Systems Management Server (SMS) or Altiris DeploymentSolution. Dell Update Packages for the PowerEdge 1855 bladeserver are available for download from the Dell support Web site atsupport.dell.com. For single-server updates, a Dell Update Packagecan be either downloaded and executed or run from the Updatetab of the OMSA GUI.DRAC/MC firmware can be updated using the Trivial FTP(TFTP) protocol over the local area network. To update the firmwarein this manner, administrators must install a TFTP serveron a system that resides on the same network segment as theDRAC/MC. The firmware image can then be updated from theTFTP server using either the DRAC/MC CLI or GUI.I/O module firmware can be updated through the interfacesprovided by the I/O modules themselves. For example, the DellPowerConnect 5316M Gigabit Ethernet switch provides for firmwareupdates from the switch GUI. In addition, firmware can be updatedusing the TFTP protocol in a manner similar to that previouslydescribed for DRAC/MC firmware.A different management paradigm for modular blade serversManaging the modular Dell PowerEdge 1855 blade server requiresa somewhat different management paradigm compared to the traditionalmethod of managing stand-alone servers. While managinga server blade is similar to managing a stand-alone server,management of the overall blade server system—including chassisinfrastructure components and individual server blades—requiresa combination of the DRAC/MC, the server blade BMC, and DellOpenManage software agents. These components work together toprovide a robust, redundant management environment—providinga holistic view of the entire system for optimal monitoring as wellas redundant notification paths to help ensure that administratorsare alerted when events occur.Steven Grigsby is a test engineer in the Dell OpenManage Product Test organization.
