Heat = #1 cause of disk failure. If they are roasting to the touch they will
fail in 2-3 months.

Subject: [asterisk-users] Asterisk Server : IDE HDD frequent crash
Hey guys,
Iam having a peculiar problem with my asterisk installation. The specs
are..
[EMAIL PROTECTED] ~]# asterisk -V
Asterisk 1.2.7.1
Wildcard: Digium Wildcard TE110P T1/E1
Wildcard TDM: Wildcard TDM400P REV I (4 modules) ( 2 FXO, 2 FXS)
Wildcard TDM: Wildcard TDM400P REV I (4 modules) ( 1 FXO, 3 FXS)
Wildcard TDM: Wildcard TDM2400P Prototype (24 modules) (12 FXO's - rest
empty)
Total 15 FX0's, 5 FXS out of which 5 to 6 FXO/FXS are being used. We have
about 300 active SIP accounts.
Queues, SIP extensions, Agents are in MySQL database using asterisk
realtime static.
CPU : Intel(R) Xeon(TM) CPU 3.06GHz with Hyper threading
RAM : 1G
Mobo : Intel SE7501HG2
The system is stable, however, the IDE disk crashes every 3/4 months.
There
are DMA timeout errors for the IDE disk before it fails completely. The
same issue occured for the past three disks and I was doubting the
recommended hdparm setting
'hdparm -d 1 -X udma2 -c 3 /dev/IDE Device'
So, I removed this setting after the last crash and the system workd fine
for another 3 months. Yes'day, the disk failed again with same symptoms.
All the disks were seagate baraccuda IDE drives.
zttool doesnt show any IRQ misses even without the above hdparm setting
and
there is no noticeable problem in asterisk with the PRI line etc. Below is
my /proc/interrupts as well as /dev/hda settings.

I looked at the mailing lists and couldnt any such issues reported.
Please advice. Should i be using SCSI disks on RAID 1 or something ? Will
that help ?
Also, should i be looking at any other mobo then Intel SE7501HG2 ? Iam
planning to put in a another asterisk server as a failover and would
appreciate inputs abt the kind of hardware i should be using for the
system
with the specs i mentioned.
Thanks
Dushyanth
