IBM System x3650 M5, Инструкция по установке и обслуживанию, Страница: 31 / 1010

The server has two PCI interface risers. See “Replacing an adapter” on page 190
for detailed information.
v
SD adapter
A raid controller for Secure Digital (SD) media. It has two upstream connections,
a USB connection to the server chipset, and an MMC connection to the
integrated management module 2.1 (IMM2.1).
v
Redundant connection
The addition of the optional Ethernet adapter provides failover capability to a
redundant Ethernet connection with the applicable application installed. If a
problem occurs with the primary Ethernet connection and the optional Ethernet
adapter is installed on the server, all Ethernet traffic that is associated with the
primary connection is automatically switched to the optional redundant Ethernet
adapter connection. If the applicable device drivers are installed, this switching
occurs without data loss and without user intervention.
v
Redundant cooling and optional power capabilities
The server supports a maximum of two 550-watt, 750-watt, or 900-watt hot-swap
power supplies and six dual-motor hot-swap fans, which provide redundancy
and hot-swap capability for a typical configuration. The redundant cooling by
the fans in the server enables continued operation if one of the fans fails. The
server comes with the minimum of one 550-watt, 750-watt, or 900-watt hot-swap
power supply and four fans.
You must install the fifth and sixth fans when you install the second
microprocessor in the server. You can order the second optional power supply
for power redundancy.
Note:
You cannot mix different wattages and different 80 plus efficiency level of
power supplies in the server.
v
ServeRAID support
The ServeRAID adapter provides hardware redundant array of independent
disks (RAID) support to create configurations. The standard RAID adapter
provides RAID levels 0, 1, and 10. An optional RAID adapter is available for
purchase.
v
Systems-management capabilities
The server comes with an IMM2.1. When the IMM is used with the
systems-management software that comes with the server, you can manage the
functions of the server locally and remotely. The IMM also provides system
monitoring, event recording, and network alert capability. The
systems-management connector on the rear of the server is dedicated to the
IMM. The dedicated systems-management connector provides additional
security by physically separating the management network traffic from the
production network. You can use the Setup utility to configure the server to use
a dedicated systems-management network or a shared network.
v
UEFI-compliant server firmware
IBM System x Server Firmware (server firmware) offers several features,
including Unified Extensible Firmware Interface (UEFI) 2.1 compliance; Active
Energy Manager technology; enhanced reliability, availability, and serviceability
(RAS) capabilities; and basic input/output system (BIOS) compatibility support.
UEFI replaces the BIOS and defines a standard interface between the operating
system, platform firmware, and external devices. UEFI-compliant System x
servers are capable of booting UEFI-compliant operating systems, BIOS-based
operating systems, and BIOS-based adapters as well as UEFI-compliant adapters.
Note: The server does not support DOS (Disk Operating System).
