>>Q: 為啥SATA SSD/HDD在Green Activity LED沒有恆亮?
>>A: LSI=> The expected behavior is a continuously lit green LED when a drive is online, optimal, and not running I/O. I expect that there may be some difference in the way the backplane is addressing the SATA drives.
>>>> Supermicro=> HDD activity LED is controlled by HDD, and its behavior is determined by its microcode.
SAS and SATA HDD will have different behavior, it is normal.
In normal state:
SAS HDD – activity LED on( green )
SATA HDD – activity LED off
>>Q: 增強型的Dimmer Switch在SATA和SAS間有沒有差異?
>>A: 有. SAS和SATA有不同的電源管理規格. SAS的優勢性更高. T10 Power State....

>>Q: 6Gb/s HDD/SSD為什麼安裝在3Gb/s MegaRAID SAS Controller, 發現Negoiation Link Speed會強制在1.5Gb/s的速率呢?
>>A: LSI=> 3Gb/s MegaRAID controllers were designed before the 6Gb/s standard was developed. The card may not automatically set the correct link rate for 6Gb/s products. We cannot guarantee that the 3Gb/s speed will automatically be negotiated to with 6Gb/s drives connected to the 3Gb/s controller.

>>Q: MegaCLI中的LDBBM是指甚麼呢? 他有甚麼用處? 如何作用?
>>A: 他指的是Logical Drive Battery Back-up Module, 指的就是BBU部分.作用方式, 根據LSI的說法如下:
If your controller supports BBUs, you are using a BBU, and you are write caching, the flag should change.
>>Q: PFK是指甚麼? 作甚麼用?
>>A: PFK就是Premium Features Key. 透過PFK可以用來啟動LSI的高階軟體服務來加值. 根據LSI的說法:
There are two types of advanced software keys: hardware and license. If you purchase a hardware key, seating the key on the board will flip a switch in the NVRAM. Removing the hardware key will change that switch back to its original state. In essence, the key is not a permanent change. In other words, you cannot purchase a hardware key, seat it on several boards, and permanently enable the feature.
License keys are permanent switches, but they are single-use. Enabling the license will make a change in the NVRAM which is permanent, but the license is automatically disabled after first use.
>>Q: MegaCLI的PFK in NVRAM是指甚麼呢?
>>A: 就是在NVSRAM存放PFK. 根據LSI的說法如下:
License keys are permanent switches, but they are single-use. Enabling the license will make a change in the NVRAM which is permanent, but the license is automatically disabled after first use.
>>Q: 這樣做有何目的?
>>A: LSI=> The goal is to prevent duplication of single licenses.
其他等我想到在補...

關於2TB以上硬盤的支持:
>2TB drives will be supported for all our 6Gb/s products and is planned for integration with our 3Gb/s MegaRAID line, though there are no current plans for future releases for the 3Gb/s HBA line. Please be sure to check our compatibility lists prior to the purchase of new drives at the interoperability tab at the link below.
expander不會對這造成影響..
你要注意的是expander對HDD的兼容性... 作者: per1-q1222 时间: 2011-1-13 02:28
