It is amazing to me at this point that there is not an official Digium list of supported servers (including 1u models!). Clearly the number 1 issue with the Digium PRI cards is the server that they are used in. The new cards even go as far as listing server that DO NOT work on the Digium site! The wiki references are old and do not have any testing parameters. C'mon guys! Certify a few current model servers and be done with it. Without that information I must again ask the question; What 1u server combos work with the new quad pri cards UNDER LOAD (more than 75% channel use). Every user that buys a Digium PRI card should not have to play hit or miss with 2 or 3 servers that cost more than the card to get it to work. Please Please Please publish something useful to support the sale of PRI cards. Damon -------------- next part -------------- An HTML attachment was scrubbed...

Damon, Here is our offering which we have extensively tested. It is VERY capable handling all 96/120 channels at once, and there are no issues between the quad card and the motherboard. We have a great number of customers running this configuration. http://www.govarion.com/product_info.php?products_id=11 Best Regards, Ben Bawkon --------- Original Message --------- From: Andrew Latham To: "Asterisk Users Mailing List - Non-Commercial Discussion" <asterisk-users@lists.digium.com> Subject: Re: [Asterisk-Users] quad t1 / 1U rack server combos Sent: 8/16/2005 1:36:45 PM My personal fav..... http://www.provantage.com/buy-7ASUN00P-asus-networking-1u-p4-bbns-e7210-52x-cd-2x64-2sata-h-2geth-300w-ap140r-e1-aa2-shopping.htm On 8/16/05, William Lloyd <wlloyd@slap.net> wrote:> I use this box with no problems at all. > > http://www.tyan.com/products/html/gx28b2881.html > > -bill > > On 16-Aug-05, at 12:32 PM, Damon Estep wrote: > > > It is amazing to me at this point that there is not an official > > Digium list of supported servers (including 1u models!).

>From what I understand (From Sangoma's tech support) and having a IBMx306 SCSI system with an A102u I believe that the system will scale up to 4xT1's easily. With a full T1 of traffic coming in and playing music on hold, the CPU was at 7% with no transcoding. Sangoma cards are supposed to place less draw on the interrupts and offer some new direct writing to DMA in their A104 cards. You may want to give them a call (Scott or Nenad are the two best people to speak with).>From Sangoma README.asterisk:Voice data is channelized and grouped into 8 byte chunks in HARDWARE. Each voice channel is then DMAed directly into the ZAPTEL buffers. Thus there is ZERO copy from HARDWARE to ZAPTEL, resulting in better performance and scalability. It sounds to me like that would be once advantage over Digiums cards. They also have Hardware PRI functions that are passed directly to libpri. http://sangoma.com/linux/README.asterisk Hope that helps.

> C'mon guys! Certify a few current model servers and be done with it.Problem is, certification is a moving target and can become invalid with something as simple as a BIOS change by the manufacturer. Now that the barrier to entry to changing a design is almost nil, manufacturers love to screw around with designs to save a few bucks. I have seen two identical boxes, labelled as such by the manufacturer, bought in the same time period, but with different guts. Digium would wind up with egg on their faces by certifying a system, then 90 days later after everyone buys it, finds out that some subtle change by the manufacturer has destabilized the config. I agree it is frustrating as hell, but this is the price we pay. Would you rather buy a Mitel for 10X the $$$? Maybe in some circumstances, it is worth it. -------------- next part -------------- An HTML attachment was scrubbed...
