Hello
I am have connected a 5 disk box ultracheap Lian Li EX-503B to a
server running XenServer 5.5.
The box is configured as raid0 with two disks and the server has a
PCIe Sil 3132.
In this circumstances the server is unable to use NCQ.
This is the card as seen with lspci -v
06:00.0 RAID bus controller: Silicon Image, Inc. SiI 3132 Serial ATA
Raid II Controller (rev 01)
Subsystem: Silicon Image, Inc. Unknown device 7132

This is the device on it

[/sys/devices/pci0000:00/0000:00:01.0/0000:06:00.0/host7/target7:0:0/7:0:0:0]
Is this expected, like a known issue between JMB393 against sil3132 ?
I was hoping to put 5 x 2Tbytes disks on this box, configure raid5 and
be happy for once.
Thanks in advance,
Sebastian Muñiz
