I2C Inter-Integrated Circuit | Dell M610 manual

Dell™ PowerEdge™ M610 Technical Guidebook

The PowerEdge M610 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 2IC-bus compatible devices incorporate an on-chip interface which allows them to communicate directly with each other via the I2C-bus. This design concept solves the many interfacing problems encountered when designing digital control circuits. These I2C devices perform communication functions between intelligent control devices (e.g., microcontrollers), general-purpose circuits (e.g., LCD drivers, remote I/O ports, memories) and application-oriented circuits.

Section 9. Embedded NICs/LOMs

A. Overview/Description

Embedded Gigabit Ethernet Controllers with TCP Offload Engine (TOE) support

One embedded dual-port Broadcom 5709C LAN controller is on the PowerEdge M610 planar as an independent Gigabit Ethernet interface device. The following information details the features of the LAN devices.

•x4 PCI Express Gen2 capable interface

•The M610 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/HBA

SECTION 10. Mezzanine Card Slots

A. Overview/Description

The PowerEdge M610 contains 2 PCIe x8 Gen 2 mezzanine card slots. Each card is a dual port. Every M610 blade can support up to 4 I/O ports (2 from each of the 2 mezzanine cards) plus the two integrated NIC/LOM ports. PLEASE NOTE: For space, the size of new mezzanine cards has been reduced and in the M610 only ONE of some older size cards can fit. Fabric C can fit any card. Fabric B can NOT fit: FC4 HBAs, Infiniband HCAs or Broadcom 5708 1Gb NICs. Mezzanine card options include:

•Emulex and QLogic dual-port 8Gb FC HBA

•Broadcom 5709 dual-port Gb Ethernet w/ TOE and iSCSI offload

•Supports IPv6 offloads, improved virtualization performance, enables

M610 to support 2 Ethernet mezzanine cards, and lowers power consumption

•Mellanox ConnectX dual-port Double Data Rate (DDR – 20Gbps) Infiniband HCA or Quad Data Rate (QDR – 40Gbps) HCA

•Broadcom dual-port 10Gb Ethernet w/ TOE and iSCSI offload
