[Bug 337419] Re: HP cciss / SmartArray responding slowly

[MikeM]

Hi,

I agree that it is not file system specific as I was testing against the block device:
dd if=/dev/cciss/c0d1 of=/dev/null bs=1024k count=1024

Furthermore, the cciss driver (which this bug is about) will not be used
by Linux when running on ESX. Changing the Linux kernel version will not
change the cciss driver used by ESX. There are plenty of threads
relating to SmartArray controllers' performance when used without BBWC -
maybe that is the problem you are seeing? Or you are asking for too many
IOPs (especially many small IOs when you application is running) from
your disk subsystem.

Regards,
Mike
