Hello,
I am using in a dual Xeon Server a SRCU42X SCSI RAID controller by
Intel. Fully equipped with 12 SCSI drives. (two different RAID5
drives). But I am fighting with a very poor performance. When
copying large files (2GB) from one directory to another I am
getting 13MB/seconds.
master ~ # uname -a
Linux master 2.6.22-gentoo-r9 #7 SMP Sun Nov 25 16:35:34 CET 2007
i686 Intel(R) Xeon(TM) CPU 3.06GHz GenuineIntel GNU/Linux
I am using the Megaraid kernel drivers.
master ~ # grep -i mega /usr/src/linux/.config
CONFIG_MEGARAID_NEWGEN=y
CONFIG_MEGARAID_MM=y
CONFIG_MEGARAID_MAILBOX=y
master ~ # lspci -v

02)
Subsystem: Intel Corporation MegaRAID Intel RAID Controller

Capabilities: [c0] Power Management version 2
Capabilities: [d0] Message Signalled Interrupts: Mask-
64bit+ Queue=0/1 Enable-
Capabilities: [e0] PCI-X non-bridge device
Also I can't use the webconsole of Intel. Not sure, if it's
expecting the kernel driver as a module. When starting the
webconsole and accessing it via http://IP:3570/ I am getting:
"No Raid Servers available"
Any ideas ?
Thanks
Stonki
