Dell™ PowerEdge™ M710 Technical Guidebook22• Unified Server Configurator (UEFI 2.1) support• Power management support including DBS, Power Inventory and multiple Power ProfilesThe PowerEdge M710 BIOS does not support the following:• Embedded Diagnostics (embedded in MASER)• BIOS language localization• BIOS recovery after bad flash (but can be recovered from iDRAC6 Express)b. i2c (inter-integrated circuit)What is I2C? A simple bi-directional 2-wire bus for efficient inter-integrated circuit control. All I2C-buscompatible devices incorporate an on-chip interface which allows them to communicate directly witheach other via the I2C-bus. This design concept solves the many interfacing problems encountered whendesigning digital control circuits. These I2 C devices perform communication functions betweenintelligent control devices (e.g., microcontrollers), general-purpose circuits (e.g., LCD drivers, remote I/Oports, memories), and application-oriented circuits.sectiOn 9. eMbeDDeD nics/lOMsa. Overview/DescriptionEmbedded Gigabit Ethernet Controllers with TCP Offload Engine (TOE) support. Four embeddedBroadcom 5709C dual-port LAN controllers are on the M710 planar as independent Gigabit Ethernetinterface devices. The following information details the features of the LAN devices.• x4 PCI Express Gen2-capable interface• The M710 operates this controller at Gen1 speed• Integrated MAC and PHY 3072x18 Byte context memory• 64KB receive buffer• TOE (TCP Offload Engine)• iSCSI controller (enabled through an optional hardware key)• RDMA controller (RNIC) (enabled post-RTS through an optional hardware key)• NC-SI (Network Controller-Sideband Interface) connection for manageability• Wake-On-LAN (WOL)• PXE 2.0 remote boot• iSCSI boot• IPv4 and IPv6 support• Bare metal deployment support• ISCSI offload - Used for offloading ISCI traffic as an ISCSI accelerator/HBAsectiOn 10. Mezzanine caRD slOtsa. Overview / DescriptionThe PowerEdge M710 contains 4 PCIe x8 Gen 2 mezzanine card slots. Each card is a dual port. EveryPowerEdge M710 blade can support up to 8 I/O ports (2 from each of the 4 mezzanine cards) plus thetwo integrated NIC/LOM ports. Mezzanine card options include:• Emulex and QLogic dual-port 4Gb or 8Gb FC HBA• Broadcom 5709 dual-port Gb Ethernet w/ TOE and iSCSI offload• Supports IPv6 offloads, improved virtualization performance, enables M710 to support 2Ethernet mezzanine cards, and lowers power consumption• Mellanox ConnectX dual-port Double Data Rate (DDR – 20Gbps) Infiniband HCA or Quad DataRate (QDR – 40Gbps) HCA• Broadcom dual-port 10Gb Ethernet w/ TOE and iSCSI offload
