similar to the same specifications of FIO; now it seems that the cost is relatively low;A lot of people are saying that SSD does not go through the RAID card performance better; I totally disagree;First, SSDs do not have a raid at all to produce use;second, the performance of the raid card degrade, even if there is not within the scope of measure; many people comment, but no one can give performance degrade percentage; personal believe less than 10%;third, the raid card may become a performance

Yesterday morning when viewing the Zabbix monitoring interface, the number of processes found on one of the servers and the 1-minute load had reached a very alarming number, the Zabbix default alarm value was the number of processes in the 5-minute average of more than 1000, and the 1-minute system load of 5 minutes with an average value greater than 5.First, the hardware and software information of the server is listed:Server hardware: Dell PowerEdge R720, 2 x Intel (R) Xeon (r) CPU e5-2640 v2

"random Read and write" performance. Mid-to high-end RAID cards are cached (at a high price). So how does the cache for the RAID card and the disk's own cache be set?The Dell server's PERC H710 RAID card has 512M cache and is battery-powered. When setting up the array (RAID5), the default option for the RAID card cache is: Read policy: Adaptive write Policy: write-back disk cache policy: Disable attribute interpretation: Read policy: General to enabl
