Question

OS: CentOS 7.6 (3.10.0-957)
    Server: PowerEdge R640
    RAID Controller: PERC H740P Mini
    Firmware Version = 5.050.00-1705
    Driver Version = 07.706.03.00-rc1

我注意到，顺序写入的最佳性能受到最初的〜1.8Gb（1GB / s）的限制，然后尽管有8GB的控制器缓存，吞吐量也越来越接近本机磁盘的吞吐量（RAID1，〜210MB / s）。写入模式为“写回，预读”。

perccli实用程序显示以下内容：

    HwCfg :
=====
ChipRevision =  B0
BatteryFRU = N/A
Front End Port Count = 0
Backend Port Count = 8
BBU = Present
Alarm = Missing
Serial Debugger = Present
NVRAM Size = 128KB
Flash Size = 16MB
On Board Memory Size = 8192MB
CacheVault Flash Size = 8.187 GB
TPM = Absent
Upgrade Key = Absent
On Board Expander = Absent
Temperature Sensor for ROC = Present
Temperature Sensor for Controller = Present
Upgradable CPLD = Absent
Current Size of CacheCade (GB) = 0
Current Size of FW Cache (MB) = 6360
ROC temperature(Degree Celsius) = 41
Ctrl temperature(Degree Celsius) = 41

任何人都可以建议什么是“ FW缓存的当前大小（MB）”吗？实际上，我有可用于写操作的缓存（“板载内存大小”-“ FW缓存的当前大小”）看起来非常可疑。还是其他原因导致此问题？

当前的FW缓存大小
