No.
we use one for the hp (nee compaq) array controllers, called cpqarrayd

Hi all,
I've just had a new server built and installed in a remote datacenter.
It's a Xeon (L5410) running AMD64, with an Adaptec 5805 8-port RAID
card, running 8 SATA 2.5 drives in RAID10. I believe the driver is aacraid.
Now all of this is very nice, but there's something that has been
Hi,
My server is a dual Opteron 265, 4GB RAM, 4x10k SCSI drives in RAID0 on
an Adaptec zero channel SmartRaid V card (the drive appears as
/dev/i2o/hda1, so it's using the i2o_block driver).
I am running fully up-to-date Debian Lenny, using the AMD64 port.
I cannot boot with the latest kernel

I'm curious as to whether anyone has experience of software RAID in
Linux giving better overall performance on RAID10 than a RAID card such
as the Adaptec 2015S.

Hi,
I am wondering if anyone has any real-world advice on the best

systems have their pros and cons, but a lot of the comparisons out there
seem to be rather old. So I'll describe below exactly what it is I'm doing.
