RAID capability, hot-pluggable SCSI hard-disk drives, thermal and power supply monitoring, redundant fans, and ECC memory. The PowerEdge 4100 systems are freestanding or can be rackmounted to integrate your servers. The microprocessor modules are installed in zero insertion force (ZIF) sockets on the system board, which allow you to replace microprocessors faster.
