Introduction to the Sun Blade X6275 Server Module
This chapter provides an overview of the features of the Oracle Sun Blade X6275 server module. This chapter also includes Sun Blade X6275 server module specifications.
The following information is included:
The following topics are covered:
The Sun Blade X6275 server module is a dual-node high-performance computing (HPC) blade. The server blade’s two compute nodes (Node 0 and Node 1) are housed on a single motherboard in a single blade enclosure. The two compute nodes within a Sun Blade X6275 server module blade are identical and symmetric, but are fully independent of each other.
Each of the two nodes in the blade are based on a two-socket Intel Xeon ® platform, which consists of the IOH24, the I/O Controller Hub 10 (ICH10R), and the I/O subsystem. Both compute nodes in the Sun Blade X6275 server module have their own ILOM service processor based on the AST2100 chip.
Each node includes a Sun Flash Module, which provides a reliable and secure boot source for the node
There are two versions of the Sun Blade X6275 server module:
Each compute node on Sun Blade X6275 IB Server Module has one 4x QDR (Quad Data Rate) InfiniBand (IB) port that interfaces to the Network Express Module (NEM) 1 slot on the Sun Blade modular system chassis midplane, for a total of two IB ports per server module.
The Sun Blade X6275 server module product features are listed in TABLE 1-1.
Two independent compute nodes, 0 and 1. The Sun Blade X6275 server module has two symmetric compute nodes, with each independent compute node containing two Intel Xeon Processor 5500 Series processors.
Up to 24 DDR3 DIMMs per blade (12 per node).
See DDR3 DIMM Guidelines.
Server modules include a service processor (SP) for each compute node. The SP provides IPMI 2.0 compliant remote management capabilities across a broad range of Sun server models. Each server module node’s SP features:
See About ILOM for more ILOM information.
Note - The chassis, the CMM ILOM and the SP ILOM must be compatible. See TABLE 1-2 for details.
Sun's Integrated Lights Out Manager (ILOM) resides on an integrated system service processor (SP) in the Sun Blade server modules. Each node contains its own SP ILOM with its own unique IP address.
The chassis also has an ILOM, called the Chassis Management Module (CMM) ILOM, which is used to manage chassis functions.
The SP ILOM can be accessed through its IP address, or through the Chassis Management Module CMM ILOM.
SP ILOM provides full remote KVMS (Keyboard, Video, Mouse, Storage) support. For remote media capabilities, SP ILOM provides remote administration through a browser-based interface, command-line interface (CLI), remote console, SNMP v1, v2c, v3, or IPMI v2.0 protocols.
A system administrator can use the out-of-band management Ethernet, or in-band communication through the server's operating system. A system administrator using out-of-band management can remotely control system power, monitor system FRU status, and load system firmware. Using in-band management, the system administrator can monitor system status and control system power-down.
Refer to the Sun Blade X6275 server module ILOM Supplement for detailed information. For general information, refer to the Integrated Lights Out Manager documentation collection.
The Sun Blade X6275 can be equipped with ILOM 2.0 or ILOM 3.0. The SP ILOM must be matched to the CMM ILOM and the chassis as follows:
In some instances, ILOM 2.0 and ILOM 3.0 work differently. The differences are noted where they occur. If no difference is noted, they work identically.
A single Sun Blade X6275 server module contains two complete systems, each referred to as a node. Each node has its own SP running its own ILOM.
ILOM 2.0 and ILOM 3.0 number the nodes differently.
The 2.0 CMM ILOM displays slot addresses as if there are two separate server modules.
- slot 18 (the actual slot number plus 12) in a Sun Blade 6048 chassis
- slot 16 (the actual slot number plus 10) in a Sun Blade 6000 chassis
This convention is reflected in the following CMM ILOM features:
For more information, see the Sun Integrated Lights Out Manager 2.0 Supplement for the Sun Blade X6275 Server Module.
ILOM 3.0 uses the actual slot number plus the node ID to identify modes.
For example in slot 6, the nodes are:
The CMM targets for the nodes in slot 6 are:
For more information, see the Sun Integrated Lights Out Manager 3.0 Supplement for the Sun Blade X6275 Server Module.
Sun Blade X6275 server modules must reside within a Sun Blade 6048 or Sun Blade 6000 modular system chassis.
The Sun Blade 6048 modular system chassis consists of four separate shelves contained within the unibody designed chassis. Up to 12 Sun Blade X6275 server modules can be installed within a single Sun Blade 6048 shelf, up to 48 server modules per Sun Blade 6048 chassis, for a maximum of 96 compute nodes per Sun Blade 6048 modular system chassis.
For more information, refer to the Sun Blade 6048 Modular System Chassis documentation.
|Note - For CMM ILOM 220.127.116.11 systems, a Sun Blade X6275 server module must be inserted into the chassis before you power on. If the blade is not inside the chassis before you power on, ILOM does not recognize node 1. For ILOM 3.0 systems, this requirement does not apply.|
The Sun Blade 6000 modular system chassis holds up to 10 Sun Blade X6275 server modules for a maximum of 20 compute nodes per Sun Blade 6000 modular system chassis.
For more information, refer to the Sun Blade 6000 Modular System Chassis documentation.
The Chassis Monitoring Module (CMM) provides a common management interface for each server module and compute node. The CMM is the primary point of management interaction for all shared chassis, components, and functions.
Through their associated ILOM service processors, all individual compute node’s IPMI, HTTPs, CLI (SSH), SNMP, and file transfer interfaces are directly accessible from the Chassis Monitoring Module (CMM) Ethernet management port. Each compute node is assigned an IP address that is used for CMM management. IP addresses for compute nodes are assigned by static or DHCP methods.
|Note - The CMM ILOM firmware must be compatible with the SP ILOM firmware. See TABLE 1-2 for compatability levels.|
This section contains Sun Blade X6275 server module specifications.
The following topics are covered:
The Sun Blade X6275 server module has the following boards installed in the blade. The boards are listed in TABLE 1-3.
The service processor board subsystem includes independent integrated lights out management (ILOM) for compute nodes 0 and 1. This SP board is attached to the motherboard and is not separately replaceable.
The service processor (ILOM) subsystem controls the host power and monitors host system events (power and environmental). The service processor (ILOM) subsystem in each compute node is powered up whenever the blade is installed in a chassis that receives AC input power, even when the main power to each compute node is off.
The Sun Blade X6275 server module form factor dimensions are listed in TABLE 1-4.
|Note - System cooling might be affected by dust and contaminant buildup. It is recommended that systems be opened and checked approximately every six months, or more often in dirty operating environments. Check system heat sinks, fans, and air openings. If necessary, clean systems by brushing or blowing contaminants or carefully vacuuming contaminants from the system.|
This section lists the CRUs and FRUs. Customer Replaceable Units (CRUs) are designed to be replaced by customers. Field Replaceable Units (FRUs) must be replaced by Sun service personnel.
|Caution - Changing FRUs can damage your equipment and void your warranty.|
