hail,
I have a problem using a port multiplier on 9.0R:
pci SATA card:
siis0@pci0:5:0:0: class=0x010400 card=0x71241095 chip=0x31241095 rev=0x01 hdr=0x00
vendor = 'Silicon Image, Inc.'
device = 'SiI 3124 PCI-X Serial ATA Controller'
class = mass storage
subclass = RAID
multiplier:
pmp0 at siisch1 bus 0 scbus1 target 15 lun 0
pmp0: <Port Multiplier 37261095 1706> ATA-0 device
pmp0: 300.000MB/s transfers (SATA 2.x, NONE, PIO 8192bytes)
pmp0: 5 fan-out ports
FreeBSD:
FreeBSD lamneth 9.0-RELEASE FreeBSD 9.0-RELEASE #0: Tue Jan 3 07:46:30 UTC 2012
root@farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64
the error is:

using the card without the multiplier, gets me around 7MB/s for ZFS+Geli. Using both, I get a
great speed (almost this) and then I begin to see those messages above, and copy speed drops to
hundreads of KB/s.
I've used this multiplier with this card:
ahci1@pci0:13:0:0: class=0x010601 card=0x10601b21 chip=0x06121b21 rev=0x01 hdr=0x00
vendor = 'ASMedia Technology Inc.'
class = mass storage
subclass = SATA
on another box, no error. but the performance is too low using geli (soekris net6501-70).
any reason for this, is a bug ? I'm looking forward on buying this:
http://www.hwtools.net/Adapter/PM362.html or http://www.hwtools.net/adapter/pm2c.html, if the
first would support multiplier, then all is fine. else, the latter would let me use the eSATA pcie
card I use on soekris, and I think all would be fine also.
if anyone would have any words of advice. My goal is to have a FreeBSD capable of ZFS, geli and
lots of disks. My mainboard is intel d525mw and 4GB ram.
so far, just using 4 disks performance is what I need.
thanks,
matheus
