I have a MySQL 5.5 runs a VMware VM with SAN storage,64GB memory ,Redhat 6.6 OS, 16 CPU cores.,The data are being inserted into DB around 200-300MB/s, total DB size is near 5TB.
Some inserts SQL with bulk data take over 60 seconds . I set innodb_file_per_table=1 , and some tables .ibd files size is over 300GB. IOSTAT often shows near 100% %util.
Are there any method can improve the IO performance by tune the Mysql or Linux parameters? and do the huge .idb file impact the I/O performance ?
