2 Site Planning Guide for Sun Blade 6000 and Sun Blade 6048 Modular Systems • October 2007

Customer ObligationsThe customer is obliged to inform Sun Microsystems, Inc. of any and all ordinancesand regulations that affect the installation. The customer is responsible for meetingall local, national, and international government codes and regulations concerningfacilities, such as safety, building, and electrical codes.

System ConfigurationThe modular configuration of the Sun Blade 6000 modular system consists of thefollowing hardware components:

■ 10U chassis (Sun Blade 6000 chassis)

■ Up to 10 Sun Blade server modules

■ 1 chassis monitoring modules (CMM)

■ Up to 2 Network Express Modules (NEMs)

■ Up to 20 PCI ExpressModules (PCI EMs)

■ 2 power supply modules

■ 6 rear fan modules


13/46


Preparing the Site Before the SystemArrivesInstall the Sun Blade 6000 modular system in accordance with the local safety codesand regulations at the facility site. You must be familiar with and adhere to thesafety precautions in the Sun Blade 6000 Modular System Safety and Compliance Manual(820-0052).

Do not make mechanical or electrical modifications to the equipment. SunMicrosystems, Inc. is not responsible for regulatory compliance of a modified Sunproduct.

Load-Bearing and Handling PrecautionsA fully configured Sun Blade 6000 modular system can weigh in excess of 400pounds (182 kg) while in its shipping container, and 350 pounds (160 kg) whenunpacked. Any floor that this system will cross, or surface on which the system isplaced, must be able to support these loads.

The system is shipped on a pallet. You must maintain the system in a vertical,upright position while it is in its shipping container. Be sure you use enoughpersonnel when moving the system, especially on sloping loading docks and ramps,to gain access to a raised computer room floor. Move the system slowly and

deliberately, and ensure that the floor is free of foreign objects, cables, or otherobstructions.

Power and Electrical RequirementsThe Sun Blade 6000 modular system uses two 200-240V, 5600W power supplymodules. The amount of power that the system consumes is dependent on itsconfiguration, that is, the number of active modular components installed. Todetermine the power redundancy requirements, you need to know:

■ Source power available

■ Power consumption (depends on component configuration)

■ Redundancy level required


14/46


The system requires a minimum of four AC inputs. To provide 2N powerredundancy at a 5600W consumption level, and to ensure that the system cantolerate a loss of one power supply, the system should never exceed 6250W of powerconsumption at any given time.

The power requirements for different components in the Sun Blade 6000 System areprovided via the power conversion calculator:

http://www.sun.com/servers/blades/6000chassis/calc/

The AC power requirements for the Sun Blade 6000 modular system are summarizedin TABLE 5.

The data center must meet the following electrical requirements for installation of a

Sun Blade 6000 System:■ Four 200–240 VAC, 16A/20A branch circuits, one for each of the AC inlets on the

system, are required.

■ The connection to the Sun Blade 6000 Chassis AC inlet requires the followingtypes of power cords, dependent on site location. Each AC inlet requires aseparate power cord; therefore, four power cords are required. The power cordmust be rated at 16A or 20A, depending on the site location.

If you are connecting the system directly to an external power source (forexample, power is not obtained through a modular power system), use thesetypes of power cords:

■ Americas Domestic – NEMA L6-20P to IEC320-C19 (4 meter, Sun part numberX5044A-Z)

■ International – IEC309 to IEC320-C19 (4 meter, Sun part number X5045A-Z)

If you are connecting the system to a (rack internal) modular power system, usethis type of power cord:

■ IEC320-C19 to IEC320-C20 (1.5 meter, Sun part number X5046A-Z; 2.0 meter,Sun part number X5047A-Z)

■ If you are using a Sun modular power system (MPS) in the cabinet, refer to thedocumentation supplied with the cabinet for the MPS power requirements.

■ If you are not using an MPS, you must supply a branch circuit with a connectorthat meets the requirements of your system.

You can configure the Sun Blade 6000 modular system for grid redundancy by usingtwo AC line feeds and the appropriate modular power system. Grid redundancyrefers to the performance of the chassis power subsystem in the intended ACconfiguration. For grid redundancy, the AC configuration is supplied by AC powerfrom two independent feeds, which can be called Line A and Line B. By connectingone power supply to the Line A feed and one power supply to the Line B feed, thesystem can tolerate the failure of one power supply or the complete loss of either ACfeed.

Power BudgetingUse the power calculator for estimating the power consumption of your system:


The intent of the power calculator is to provide guidance for estimating the electricaland heat loads for chassis racking and facilities planning purposes. The "Maxpower" results shown (at 100% workload) represent server module powerconsumption measurements with CPUs at 100% utilization. The "Idle power" resultsshown represent power consumption measurements taken from server moduleswith operating systems booted and stabilized, yet running at minimal utilization.

Results shown by the calculator are representative of measurements taken with roomtemperatures below 25 oC. Actual power consumption will vary with applicationtype, application utilization and ambient temperature. Whenever possible, actualmeasurements are recommended. Use these specifications for planning purposesonly. The system’s actual power requirements are dependent on which componentsare included in your configuration.

Cooling RequirementsEvery watt of power used by the system is dissipated into the air as heat. The upperlimit of thermal power dissipation of the chassis in 6250W 2N configuration is 21,325BTU/hr. This requires that the data center heating, ventilation, and air conditioning(HVAC) system must accommodate the maximum heat release of a fully configuredsystem, as well as any other systems in the data center.

The amount of heat output per Sun Blade 6000 system varies, depending on thesystem configuration. The systems are equipped with fans that route cool airthroughout the chassis from front to rear. The fans are speed-controlled based onsystem temperature sensors. Typical airflow (for room temperatures below 23 oC) isabout 600 CFM. Maximum possible airflow is about 1012 CFM.

As long as the necessary air conditioning is provided in the data center to dissipatethe heat load, and sufficient space and properly vented door openings are provided

at the front and back of rackmounted systems (see TABLE 1), the system fans willenable the system to work within the temperature specifications for systems inoperation (see TABLE 6). Thermal characteristics of the Sun Blade 6000 Chassis systemare provided in TABLE 7.



16/46


Temperature and Humidity RequirementsAvoid temperature and humidity extremes. The operating and nonoperating

temperature specifications listed in TABLE 6 reflect the system’s hardware limits, inorder to meet all functional requirements. Note that the operating temperaturesapply to the air entering the system and not necessarily the temperature of the air inthe aisles.

The optimum operating ambient temperature and humidity ranges are therecommended operating environment. Operating the system within the ambienttemperature range is optimal for system reliability. At 23 oC (73.4 oF) it is easy tomaintain safe relative humidity ranges and to provide a buffer if the environmental

support system fails.

Ambient relative humidity levels between 45% and 50% are the most suitable forsystem operations to:

■ Prevent corrosion.

■ Provide an operating time buffer in the event of an environmental control systemfailure.

■ Help avoid failures due to intermittent interference from static discharges that canoccur when relative humidity is too low. Electrostatic discharge (ESD) is easilygenerated and less easily dissipated in areas where the relative humidity is below35%, and becomes critical when levels drop below 30%.

Conditions should not be allowed to fluctuate by more than 5.5 oC (10 oF) or 10%relative humidity during a 60-minute period.

Airflow RequirementsThe system uses forced air to draw in ambient air for cooling from the front of thechassis, while heated air exits the rear of the chassis. The design of the systemprovides two primary regions of airflow: The lower airstream cools the ServerModules, and the upper airstream cools the power supplies, Chassis MonitoringModules, Sun Blade 6000 Network Express Modules, and PCI Express Modules.

The rear fan cage includes six rear fan modules, each module having two fans, for atotal of 12 fans. The fans draw cool air through the front of the Server Modules andexhaust heated air through the back of the chassis. This results in a typicalmeasurement of approximately 600 CFM (cubic feet per minute) of total airflow.

The upper airstream provides forced air by using a combination of internal fanswithin each power supply.

Follow these airflow guidelines:

■ Do not block the ventilation areas of the chassis.


17/46


■ Ensure that all cabling at the rear of the chassis does not block any exhaust air.

■ Ensure that front and rear cabinet doors are at least 60% perforated to ensureminimal restriction of airflow. Removal of either or both doors will improve the

cooling capability of the system.■ Front and rear clearance between the cabinet doors and the system should allow

a minimum of 0.2 inch (0.5 cm) at the front of the system and 3.1 inches (7.9 cm)at the rear of the system for proper airflow.

Clearance for Service and Aisle RequirementsTo enable installation and servicing of the system, including access to system cables,follow these space restrictions.

Arrange racks in a hot aisle/cold aisle layout. This layout enables cool air to flowthrough the aisles to the system’s front air intake and enables heated air to flow fromthe system’s back exhaust. A hot aisle/cold aisle layout eliminates the direct transfer

of hot exhaust air from one system into the intake air of another system.

Rackmounting ConsiderationsThis section describes information that you need to consider when planning to

rackmount the systems.

Compatible CabinetsThe chassis is designed for rackmounting. It can be mounted into 19-inch EIA-310Dcabinets with a depth of 35.4 to 39.4 inches (90.0 to 100.1 cm). The chassis can

accommodate corresponding front-to-back, rail-to-rail spacing of 26.77 inches(68.0 cm) to 34.25 inches (87.0 cm).

Route to the Data CenterIdeally, the data center and loading dock should be located in close proximity to oneanother. The access allowances for the path from the loading dock to the data centermust include:

■ A minimum 56-inch (142-cm) height

■ A minimum 37-inch (94-cm) width (greater is recommended)

The system chassis and factory-installed components ship in a single container on apallet. The system must be kept in a vertical, upright position at all times while in itsshipping container. Ensure that the equipment and personnel unloading the chassisshipping container can accommodate the shipping dimensions and weight of thecontainer. See TABLE 3 for shipping container and weight specifications.

If there is a significant temperature or humidity difference between the system andthe data center environment, keep the system in its shipping container in a locationthat has a similar temperature and humidity environment to the data center. Wait at

least 24 hours before removing the system from its shipping container to preventthermal shock and condensation.

Provide a room that is separate from the data center in which to open equipmentcartons and to repack hardware when you install and remove parts. Avoidunpacking the cartons in the data center. Dirt and dust from the packing materialscan contaminate the data center.

Facility SafetyObserve the following guidelines and precautions when installing the Sun Blade6000 modular system.

Secure Installation RequirementsTo minimize personal injury in the event of a seismic occurrence, you must securelyfasten the cabinet in which the system is rackmounted to a rigid structure extendingfrom the floor to the ceiling, or from the walls, of the room in which the cabinet islocated.


20/46


Install a stand-alone system or a rackmounted system on a level surface. At the baseof the cabinet is an anti-tilt bar. This bar must be extended before you install theSun Blade 6000 modular system to prevent the cabinet from moving.

Placement of a Sun ProductDo not block or cover the openings of the Sun Blade 6000 modular system. Neverplace a Sun product near a radiator or heat register. Failure to follow theseguidelines can cause overheating and affect the reliability of your Sun product. Aircools the Sun Blade 6000 modular system from front to back. The front and rear

cabinet door clearances must provide sufficient space for cooling. See “AirflowRequirements” on page 6 for specific clearance specifications.

Hazardous Conditions PrecautionBecause of the inherent nature of the system’s modular design, care must be taken to

ensure that operators are not exposed to moving parts and sharp edges.

Customer ObligationsThe customer is obliged to inform Sun Microsystems, Inc. of any and all ordinancesand regulations that affect the installation. The customer is responsible for meetingall local, national, and international government codes and regulations concerningfacilities, such as safety, building, and electrical codes.

System ConfigurationThe Sun Blade 6048 modular system consists of four shelves, with the followingmaximum configuration for each shelf:

■ 12 server modules

■ 1 chassis management module (CMM)

■ 24 PCI ExpressModules (PCI EM)■ 2 network express modules (NEMs)

■ 2 power supplies



31/46


Preparing the Site Before the SystemArrivesInstall the Sun Blade 6048 modular system in accordance with the local safety codesand regulations at the facility site. You must be familiar with and adhere to thesafety precautions in the Modular Systems Safety and Compliance Manual for Sun Blade6000 and Sun Blade 6048 (820-0052).

Do not make mechanical or electrical modifications to the equipment. SunMicrosystems, Inc. is not responsible for regulatory compliance of a modified Sunproduct.

Load-Bearing and Handling PrecautionsA fully configured Sun Blade 6048 modular system can weigh in excess of 2500

pounds (1134 kg) while in its shipping container, and 2300 pounds (1044 kg) whenunpacked. Any floor that this system will cross, or surface on which the system isplaced, must be able to support these loads.

The system is shipped on a pallet. You must maintain the system in a vertical,upright position while it is in its shipping container. Be sure you use enoughpersonnel when moving the system, especially on sloping loading docks and ramps,to gain access to a raised computer room floor. Move the system slowly anddeliberately, and ensure that the floor is free of foreign objects, cables, or otherobstructions.

Power and Electrical RequirementsThe Sun Blade 6048 modular system uses two 200-240V, 8400W power supplymodules per shelf. The amount of power that the system consumes is dependent on

its configuration, that is, the number of active modular components installed. Todetermine the power redundancy requirements, you need to know:

■ Source power available

■ Power consumption (depends on component configuration)

■ Redundancy level required


32/46


The system requires a minimum of two AC inputs per shelf. To provide 2N powerredundancy at a 8400 W consumption level, and to ensure that the system cantolerate a loss of three power supplies, the system should never exceed 9375 W pershelf of power consumption at any given time.

The power requirements for different components in the Sun Blade 6048 System areprovided via the power calculator:


The AC power requirements for the Sun Blade 6048 modular system are summarizedin TABLE 4.

The data center must meet the following electrical requirements for installation of aSun Blade 6048 System:

■ Four 200–240 VAC, 16A/20A branch circuits, one for each of the AC inlets on thesystem, are required.

■ The connection to the Sun Blade 6048 Chassis AC inlet requires the followingtypes of power cords, dependent on site location. Each AC inlet requires aseparate power cord; therefore, four power cords are required. The power cordmust be rated at 16A or 20A, depending on the site location.

If you are connecting the system directly to an external power source (for

example, power is not obtained through a modular power system), use thesetypes of power cords:

■ Americas Domestic – NEMA L6-20P to IEC320-C19 (4 meter, Sun part numberX5044A-Z)

■ International – IEC309 to IEC320-C19 (4 meter, Sun part number X5045A-Z)

If you are connecting the system to a (rack internal) modular power system, usethis type of power cord:

■ IEC320-C19 to IEC320-C20 (1.5 meter, Sun part number X5046A-Z; 2.0 meter,Sun part number X5047A-Z)

■ If you are using a Sun modular power system (MPS) in the cabinet, refer to thedocumentation supplied with the cabinet for the MPS power requirements.

■ If you are not using an MPS, you must supply a branch circuit with a connectorthat meets the requirements of your system.

You can configure the Sun Blade 6048 modular system for grid redundancy by usingtwo AC line feeds and the appropriate modular power system. Grid redundancyrefers to the performance of the chassis power subsystem in the intended ACconfiguration. For grid redundancy, the AC configuration is supplied AC powerfrom two independent feeds, which can be called Line A and Line B. By connectingone power supply to the Line A feed and one power supply to the Line B feed, thesystem can tolerate the failure of one power supply or the complete loss of either ACfeed.



33/46


Power BudgetingUse the power calculator for estimating the power consumption of your system:


The intent of the power calculator is to provide guidance for estimating the electricaland heat loads for chassis racking and facilities planning purposes. The "Maxpower" results shown (at 100% workload) represent server module powerconsumption measurements with CPUs at 100% utilization. The "Idle power" resultsshown represent power consumption measurements taken from server moduleswith operating systems booted and stabilized, yet running at minimal utilization.

Results shown by the calculator are representative of measurements taken with roomtemperatures below 25 oC. Actual power consumption will vary with applicationtype, application utilization and ambient temperature. Whenever possible, actualmeasurements are recommended. Use these specifications for planning purposesonly. The system’s actual power requirements are dependent on which componentsare included in your configuration

Cooling RequirementsEvery watt of power used by the system is dissipated into the air as heat. Thethermal power dissipation of the shelf in a 9375W 2N configuration is 32,000 BTU/h.This requires that the data center heating, ventilation, and air conditioning (HVAC)system must accommodate the maximum heat release of a fully configured system,as well as any other systems in the data center.

The amount of heat output per Sun Blade 6048 System varies, depending on thesystem configuration. The systems are equipped with fans that route cool airthroughout the chassis from front to rear. The fans are speed-controlled based onsystem temperature sensors. Typical airflow (for room temperatures below 23 oC) isabout 844 CFM per shelf. Maximum possible airflow is about 1460 CFM per shelf.

As long as the necessary air conditioning is provided in the data center to dissipatethe heat load, and sufficient space and properly vented door openings are provided

at the front and back of rackmounted systems (see TABLE 1), the system fans willenable the system to work within the temperature specifications for systems inoperation (see TABLE 5). Thermal characteristics of the Sun Blade 6048 Chassis systemare provided in TABLE 6.



34/46


Temperature and Humidity RequirementsAvoid temperature and humidity extremes. The operating and nonoperatingtemperature specifications listed in TABLE 5 reflect the system’s hardware limits, inorder to meet all functional requirements. Note that the operating temperaturesapply to the air entering the system and not necessarily the temperature of the air inthe aisles.

The optimum operating ambient temperature and humidity ranges are therecommended operating environment. Operating the system within the ambienttemperature range is optimal for system reliability. At 23 oC (73.4 oF) it is easy tomaintain safe relative humidity ranges and to provide a buffer if the environmental

support system fails.Ambient relative humidity levels between 45% and 50% are the most suitable forsystem operations to:

■ Prevent corrosion.

■ Provide an operating time buffer in the event of an environmental control systemfailure.

■ Help avoid failures due to intermittent interference from static discharges that canoccur when relative humidity is too low. Electrostatic discharge (ESD) is easilygenerated and less easily dissipated in areas where the relative humidity is below35%, and becomes critical when levels drop below 30%.

Conditions should not be allowed to fluctuate by more than 5.5 oC (10 oF) or 10%relative humidity during a 60-minute period.

Airflow RequirementsThe system uses forced air to draw in ambient air for cooling from the front of thechassis, while heated air exits the rear of the chassis. The design of the systemprovides two primary regions of airflow: The lower airstream cools the ServerModules, and the upper airstream cools the power supplies, Chassis MonitoringModules, Sun Blade 6048 Network Express Modules, and PCI Express Modules.

The rear fan cage includes eight rear fan modules, each module having two fans, fora total of 16 fans. The fans draw cool air through the front of the Server Modules andexhaust heated air through the back of the chassis. This results in typicalmeasurements of approximately 844 CFM (cubic feet per minute) of total airflowthrough a shelf.

The upper airstream provides forced air by using a combination of internal fanswithin each power supply.

F ll h i fl id li


35/46


Follow these airflow guidelines:

■ Do not block the ventilation areas of the system.

■ Ensure that all cabling at the rear of the system does not block any exhaust air.

Clearance for Service and Aisle RequirementsTo enable installation and servicing of the system, including access to system cables,follow these space restrictions.

Arrange cabinets in a hot aisle/cold aisle layout. This layout enables cool air to flowthrough the aisles to the system’s front air intake and enables heated air to flow fromthe system’s back exhaust. A hot aisle/cold aisle layout eliminates the direct transferof hot exhaust air from one system into the intake air of another system.

Route to the Data CenterIdeally, the data center and loading dock should be located in close proximity to oneanother. The access allowances for the path from the loading dock to the data centermust include:

■ A minimum 87-inch (221-cm) height

■ A minimum 37-inch (94-cm) width (greater is recommended)

The system chassis and factory-installed components ship in a single container on a

pallet. The system must be kept in a vertical, upright position at all times while in itsshipping container. Ensure that the equipment and personnel unloading the chassisshipping container can accommodate the shipping dimensions and weight of thecontainer. See TABLE 2 for shipping container and weight specifications.

If there is a significant temperature or humidity difference between the system andthe data center environment, keep the system in its shipping container in a locationthat has a similar temperature and humidity environment to the data center. Wait atleast 24 hours before removing the system from its shipping container to preventthermal shock and condensation.

36/46


Provide a room that is separate from the data center in which to open equipmentcartons and to repack hardware when you install and remove parts. Avoidunpacking the cartons in the data center. Dirt and dust from the packing materialscan contaminate the data center.

Facility SafetyObserve the following guidelines and precautions when installing the Sun Blade6048 modular system.

Secure Installation RequirementsTo minimize personal injury in the event of a seismic occurrence, you must securelyfasten the cabinet in which the system is installed to a rigid structure extending fromthe floor to the ceiling, or from the walls, of the room in which the cabinet is located.

Install the cabinet on a level surface. At the base of the cabinet is an anti-tilt bar. This bar must be extended before you install the Sun Blade 6048 modular system toprevent the cabinet from moving.

Placement of a Sun Product

Caution – Failure to follow the following guidelines can cause overheating andaffect the reliability of your system.

Do not block or cover the openings of the Sun Blade 6048 modular system. Neverplace a Sun product near a radiator or heat register. Air cools the Sun Blade 6048modular system from front to back. The front and rear cabinet door clearances must

provide sufficient space for cooling. See “Airflow Requirements” on page 24 forspecific clearance specifications.

Hazardous Conditions PrecautionBecause of the inherent nature of the system’s modular design, care must be taken toensure that operators are not exposed to moving parts and sharp edges.
