asterisk users - May 2006 - DELL PowerEdge 2850 and TE4110P and TE110P

Hi All
     Before I go out and buy a DELL PowerEdge 2850 has anyone had
problems (or any other useful experience) getting a TE411P to work with
it. I also have a legacy TE110P. Has anyone had problems with this combo.

I can not talk about Digium, but 2850 with Sangoma A102 works fine here 
(standard Debian 2.4.27 kernel)

Hello Julian!

As we are using the same HW (2850 and Sangoma cards) but have some problems with
AMI (* manager interface) I wonder which OS (version of Linux, kernel version)
are you using?

Thanks!

We have a 2850 running with a Sangoma A102 , 50 agents using 
Agentcallbacklogin and around 4000 calls per day. No problems at all.

With a te410 / 405 (we've got both, can't remember which one was in the 
dell) we had lockups almost every day.

We have problems with 'loosing' parts of messages sent from Asterisk
Manager to our CTI Server (we also tested it with another test program, but the
problem persisted). Sometimes (once per 4000 lines or so - depending on speed of
network) manager improperly returns events. For example, one QueueMember will
get overwritten by (or as part of) another, like this (see third line):

Event: QueueMember
Queue: 09
LocatiEvent: QueueMember
Queue: 09
Location: Agent/09003
Membership: static
Penalty: 1
CallsTaken: 0
LastCall: 0
Status: 5
Paused: 0

We are using Red Hat ES Linux 4 (the same 2.6.9-22 kernel) but
SVN-branch-1.2-r27093M. We also noticed that problem seems to be fixed in trunk,
but we are not 'brave' enough to use trunk in production environment.

But obviously your experiences with using trunk in production are quite good.
Hmm....

What problems are you having ?

We are using CentOS 4.2 Linux 2.6.9-22.0.1.ELsmp

Asterisk SVN-trunk-r7353M

I know, time to update, but I am not in the office currently and do 
*not* want to do it remotely ;)

I tried using a TE110P and a TE210P. The irq hit percentage on the Dell 
with zttest is quite disappointing, even after tweaking. It's just above 
the minimum requirement

Also the 2850 is *always* sharing IRQ's on every PCI slot, you need to buy 
a dual port ethernet adapter which will use only one irq to free up an IRQ 
on another slot. This just totally sucks and irq sharing in a box with 
only 3 pci slots is totally unnecessary

I'm now using the 2850 with one TE210P, system is in production use since 
the 1st of May and no lockups or apparent problems so far.

I would have expected better from the 2850 however and would not buy one 
again

Sangoma cards are said to be better but I preferred to support Digium and 
I don't want to mess around with additional drivers

Just my $0.02

Sorry I'm late, just joined the list.

We have 400 seats spread across 8 Dell 2805's, and were running TE410P's
in
all of them.  After six months of troubleshooting call drops, static, and
random server lockups, we moved 4 of the servers to Sangoma A104d's last
week.  The problems we were having have basically disappeared.

Keep in mind, this is after trying PCI based NIC's and ensuring there were
NO IRQ's being shared, messing with APIC, ACPI, irq latency, and a host of
other settings - NOTHING seemed to help, until we dropped the Sangoma in and
installed the drivers.  It's been smooth sailing since.

HTH,

Wes

currently running asterisk 1.2.4, zaptel 1.2.5, and no libpri (we're running
robbed-bit T1's, E&M Wink signalling.  a migration to PRI is scheduled,
and
we'll be running the current version at that time).  i also plan on
upgrading to the new asterisk and zaptel versions as soon as i've had a
chance to test...

What were the kernel parameters that you changed? (what OS, by the
way?)

we're running fedora core 4 with the stock kernel, but a move to either
CentOS, Debian, or just running Pound Key might be in the works.
i currently have the following options added:  vga=normal nmi_watchdog=0
acpi=off
i had also tried noapic and leaving the nmi_watchdog flag off entirely,
didn't seem to make much difference.

sorry this isn't in the thread - i'm still getting used to using a
mailing
list, it's a first for me.
