Configure Networking
Each Cisco UCS C220 M4 server has one onboard Intel I350 1-Gbps network controller, which has two 1-Gbps network ports
and one Cisco UCS VIC 1227 10-Gbps dual-port CNA SFP+ adapter. Both the 1-Gbps network ports are configured for ESXi,
SvSAN VSA, and virtual machine management. The servers are connected back to back using the Cisco UCS VIC 1227 for
SvSAN iSCSI, mirroring, and vMotion traffic. Configure each 10-Gbps port with a maximum transmission unit (MTU) of 9000
through the Cisco Integrated Management Controller (IMC): choose

Configure Storage
Each Cisco UCS C220 M4 server has two 32-GB FlexFlash SD cards and eight 1.2-TB SAS hard drives. In this configuration,
ESXi is booted from the on-board mirrored (RAID 1) FlexFlash SD cards. For more information, see Cisco FlexFlash: Use
and Manage Cisco Flexible Flash Internal SD Card for Cisco UCS C-Series Standalone Rack Servers. The FlexFlash SD card
mirrored (RAID 1) configuration is performed through the Integrated Management Controller, as shown in the FlexFlash sample
