You can map sram0 and Rom to this address, that is, use the control register to select ROM and sram0 to map to the boot memory location. If you access the boot memory address, that is, the ROM or sram0 address mapped to this location. For example, if the boot memory is mapped to sram0, the access loca

In the past few days, the write policy of the RAID card is switched back to WT from WB. If "Learn cycle" occurs during business peaks, it will seriously affect the performance of the database. After the problem is solved, sort out your understanding of these problems. I will not describe the megacli command set I have used. There are a lot of information about it on the Internet.

1 IntroductionThe RAID card battery on the server, referred to as the BBU, is a very important component, it has a large impact on the I/O performance of the disk, but the general Bbu power can only be used for 90 days, the system will automatically charge it after the power is exhausted, but it usually takes a few hours to charge, during charging, The cache status of the RAID card is in write through, i.e. without the caching feature. So in order to ensure that the server is in normal operation
