Chapter 1: Introduction Chapter 1 Introduction 1-1 Overview The A+ Server 2021TM-BTRF/BIBXRF is a high-end server comprised of two main subsystems: the SC827 2U server chassis and the H8DMT-F/H8DMT-IBXF dual processor serverboard. Please refer to our web site for information on operating systems that have been certiﬁ ed for use with the system (www.supermicro.com). In addition to the serverboard and chassis, various hardware components have been included with the 2021TM-BTRF/BIBXRF, as listed below:

Eight passive CPU heatsinks (SNK-P0022+) Four 8-cm chassis fans (FAN-0111L4) Four air shrouds (MCP-310-82703-0B) Four riser cards (RSC-R1U-E16R-O-P) SATA Accessories One SATA backplane (BPN-SAS-827B) Four 16-pin to 16-pin front control cable (CBL-0151L) Four sets of SATA cables (CBL-0317L) Four 4-pin fan cables (CBL-0320L) Four 4-pin to 4-pin I2C cables (CBL-0323L) Twelve 3.5" hot-swappable drive carriers (MCP-220-00024-0B) One rackmount kit (MCP-290-00053-0N) One CD containing manual, drivers and utilities 1-1

A+ SERVER 2021TM-BTRF/BIBXRF User's Manual 1-2 Serverboard Features At the heart of the A+ Server 2021TM-BTRF/BIBXRF lies the H8DMT-F/H8DMT- IBXF, a dual processor serverboard based on the nVidia MCP55 Pro Chipset and designed to provide maximum performance. Up to four of these serverboards can be mounted in the SC827 chassis. The 2021TM-BTRF server contains the H8DMT-F serverboard, while the 2021TM-BIBXRF contains the H8DMT-IBXF serverboard. The difference between the H8DMT-F and H8DMT-IBXF serverboards are the availability of Inﬁ niBand components. Refer to the table below for details.

The sections below cover the main features of the H8DMT-F/H8DMT-IBXF serverboards (see Figure 1-1 for a block diagram of the chipset). Processors The H8DMT-F/H8DMT-IBXF supports single or dual AMD Opteron 2000 series processors (Socket F type). Please refer to the serverboard description pages on our web site for a complete listing of supported processors (www.supermicro.com). Memory The H8DMT-F/H8DMT-IBXF has eight 240-pin DIMM slots that can support up to 64 GB of DDR2-800/667/533 registered ECC SDRAM. The memory operates in an interleaved conﬁ guration and requires modules of the same size and speed to be installed two at a time. See Chapter 5 for details.

Serial ATA A Serial ATA controller is integrated into the nVidia MCP55 Pro Chipset to provide a four-port 3 Gb/s SATA subsystem, which is RAID 0, 1, 5 and JBOD supported. The SATA drives are hot-swappable units. Note: The operating system you use must have RAID support to enable the hot- swap capability and RAID function of the SATA drives. PCI Expansion Slots The H8DMT-F/H8DMT-IBXF has one PCI Express x16 expansion slot. 1-2 Serverboard Full IPMI Capability Infi niBand Components H8DMT-F X H8DMT-IBXF X X

Chapter 1: Introduction One Fast UART 16550 compatible serial port and a Mellanox Connect-X MT25408 20Gb/s Inﬁ niBand controller are located on the serverboard. The color-coded I/O ports include one COM port (an additional COM header is located on the serverboard), a VGA (monitor) port, two USB 2.0 ports (additional 2+2 internal USB headers are included on the serverboard) and two gigabit Ethernet ports. Onboard Controllers/Ports Graphics Controller The H8DMT-F/H8DMT-IBXF features an integrated Windbond WPCM450 BMC graphics controller.

Other Features Other onboard features that promote system health include onboard voltage monitors, a chassis intrusion header, auto-switching voltage regulators, chassis and CPU overheat sensors, virus protection and BIOS rescue. 1-3 Server Chassis Features The following is a general outline of the main features of the SC827 server chassis. System Power Each SC827 chassis model includes a high-efﬁ ciency 80 Plus Gold certiﬁ ed power supply, rated at 1200 Watts plus one redundant backup power supply. In the unlikely event your power supply fails, replacement is simple and can be accomplished without tools.

SATA Subsystem The SC827 supports up to twelve 3.5" hot-swap SATA drives in trays (3 for each node). These drives are hot-swappable units and are connected to a backplane that provides power and control. Note: The operating system you use must have RAID support to enable the hot- swap capability of the drives. 1-3

A+ SERVER 2021TM-BTRF/BIBXRF User's Manual SC827 models include four front panels on the handles of the chassis which control each of the systems. Each control panel on the A+ Server 2021TM-BTRF/BIBXRF provides you with system monitoring and control for one server node. LEDs indicate system power, HDD activity, network activity, system overheat and power supply failure. A main power button and a system reset button are also included. Front Control Panel I/O Backplane The SC827 is an ATX form factor chassis designed to be used in a 2U rackmount conﬁ guration.

The SAS827B I/O backplane provides a low-proﬁ le add-on card slot, a COM port, a VGA port, two USB 2.0 ports and two gigabit Ethernet ports per node. For more information regarding the backplane, view the appendices found at the end of this manual. Cooling System The SC827 chassis accepts four system fans powered from either backpane or the serverboards. If not powered from the backpane, the SC827B model chassis powers two fans from two motherboards, so that when one of the motherboard drawers is removed, the second motherboard will continue running both fans. Air Shrouds The SC827 chassis includes four mylar air shrouds that direct the airﬂ ow where cooling is needed on each serverboard.

Always use the air shroud included with your chassis on each serverboard. Mounting Rails The SC827 includes a set of quick-release rails, and can be placed in a rack for secure storage and use. To setup your rack, follow the step-by-step instructions included in this manual. 1-4
