Hi,
I've just purchased a pile of Areca 1210 controllers, having seen that
they should perform well with FreeBSD. Now having hooked up a pair of
them to 4 WD 250gb SATA drives and configured them to RAID1+0, I see
them perform very, very badly.
Below is a typical test I run on newly created arrays, to see the
sustained write speeds they can handle. It's nowhere near a real-world
test, but I've found it to often reveal issues early on.
As you can see, the Areca seems to accept a lump of data (filling its
write cache) early on, then practically slows to a crawl, and for long
stretches of time no data is written at all, before another burst is
written followed by trickling, repeat ad infinitum.
I've repeated this with HDD cache on and off, controller cache on and
off, NCQ on and off and at both SATA150 and SATA300 speeds. When
disabling the controller cache (setting it to write-through), I don't
get the initial burst, but a slow trickle of data ~5-15 mbytes/sec.
While this is going on, the system is basically unresponsive. There is
nothing else going on, only sshd running.
I've just updated the firmware to the latest as of today, however that
didn't change anything.
I'm on FreeBSD 7.1-RELEASE. Dmesg output below.
Can anyone point me in the right direction here?
Thanks,
/Eirik
