有没有介绍T5xx0主机的2个电源是如何工作的文档

Question

比如是active-standy, 还是dual active，如果是active/standby模式，那么当active power电源失效，standy如何判断该马上接管过来，此外判断电源好坏的关键部件是power distribution board吗？

Answer 1

谢谢4楼的解释

Answer 2

学习了

Answer 3

终于等到高人出现了

Answer 4

2个都是active的，只是在工作的那个功率大点。另外一个始终在监视另外一个。所以功率不是很大的。

Answer 5

可以参考一些专业的HA软件。。。

Answer 6

学习。

Answer 7

虽然很多服务器在参数里面说 dual active ，但实际测下来，用专用测电流仪器或者查看UPS的功率，发现一路总是比另一路功率高，而且不是一点点。

一般在服务器安装时，要注意电源线布线分摊到两个UPS问题

像T5系列的机器，可以通过ILOM知道电源已经坏了，列子如下：

如下式JTF关于电源部分的说明：

Main Power Supplies
The Sun SPARC Enterprise T5x40 main system power supply modules provide the chassis with 12
Volts DC at current levels ranging from 50 to 80 Amperes and a modest amount of 3.3 Volt standby
power. Both 1U and 2U systems feature two hot swappable AC to DC power supply bays permitting
N+1 redundancy, such that a fully configured system can operate indefinitely using a single power
supply. A second bay is provided for an additional, identical power supply to be installed for
redundancy. The second bay should not be left completely open; in the case of only one supply
being used, a filler panel must be inserted due to air flow considerations. There is no inherent
preference as to which bay to use when the Sun SPARC Enterprise 5x40 is powered by only one
supply.
When both power supply bays are populated, the output current will be shared. Thus, some amount
of system power will be delivered by each supply. The combined utilization level will be at an
equivalent level of 50% or less of their combined maximum capacity.

Answer 8

小弟 先说  ：  还第一次听说这事 ，应该都是ACTIVE的 不是机柜里那种STANDBY的分电模块

应该是PDB
高人说。。。。。。。

Answer 9

关注一下，应该是power distribution board，等待高人出现
