Sun Blade 8000 Series Site Planning Guide • February 2008
With the Sun Blade 8000 system, to provide a full N+N (3+3 ) power redundancy at
a 9000W consumption level, and to ensure that the system can tolerate a loss of three
power supplies, the system should never exceed 9000W of power consumption at
any given time. If you need only N+1 redundancy (loss of up to one power supply
without suffering any outage), the system should contain four active power supplies.
For N+2 redundancy (loss of up to two power supplies without suffering any
outage) the system should contain five active power supplies.
You can configure the Sun Blade 8000 Modular System for grid redundancy by using
two AC line feeds and the appropriate modular power system.
Grid redundancy
refers to the performance of the chassis power subsystem in the intended AC
configuration. For grid redundancy, the AC configuration is supplied AC power
from two independent feeds, which can be called Line A and Line B. By connecting
three power supplies to the Line A feed and three power supplies to the Line B feed,
the system can tolerate the failure of up to three power supplies or the complete loss
of either AC feed.
The Sun Blade 8000 P Modular System supports N+1 power supply redundancy. A
minimum of three operating power supplies are required to support a fully
configured system without N+1 power supply redundancy.
Power Cord Requirements
The connection to the Sun Blade 8000 Series chassis AC inlets requires the following
types of power cords, which are dependent on site location. Each AC inlet requires a
separate power cord; therefore, six power cords are required for the Sun Blade 8000
Chassis and four power cords are required for the Sun Blade 8000 P Chassis. The
power cord must be rated at 16A or 20A, depending on the site location.
If you are connecting the system directly to an external power source or to a
modular power system, use these types of power cords:
■
Sun Blade 8000 Chassis:
■
Americas Domestic - NEMA L6-20P to IEC320-C19 (13 feet/4 meter; Sun part
number X5044A-Z)
■
International - IEC309 to IEC320-C19 (13 feet/4 meter; Sun part number
X5045A-Z)
■
Optional power cord for connecting a rackmounted chassis to a modular
power system - IEC320-C19 to IEC320-C20 (5 feet/1.5 meter; Sun part number
X5046A-Z); (6 feet/2 meter; Sun part number X5047A-Z)
■
Sun Blade 8000 P Chassis:
■
Americas Domestic - NEMA L6-20P to IEC320-C19 (13 feet/4 meter; Sun part
number X5074A-Z)
■
International - IEC309 to IEC320-C19 (13 feet/4 meter; Sun part number
X5075A-Z)
