In an attempt to moderate Linux VM I/O throughput in a host with both Linux and Windows VMs, I am interested in reducing the Linux disk Queue depth.
In looking at the /proc information for the LSI Logic SCSI module, see below, it looks like MaxQ is something that might be relevant.
#cat /proc/scsi/mptspi/0
ioc0: LSI53C1030 B0, FwRev=01032920h, Ports=1, MaxQ=128
However, when I examine the module parameter for mptspi, MaxQ is not listed as a parameter.
#modinfo -p mptspi
mpt_saf_te: Force enabling SEP Processor: enable=1 (default=MPTSCSIH_SAF_TE=0)
So, my question is whether or not MaxQ number is adjustable for the LSI Logic driver on Linux VM? If so, how can it it done?
Thanks for any help in advance !
