求助，DE210E卡的问题

hi 我今天在使用卡时发现大量的警告信息，如下：

运行环境，通话并发150路情况下。
配置：zaptel.conf
span=1,1,0,ccs,hdb3
bchan=1-15,17-31
hardhdlc=16

span=2,2,0,ccs,hdb3
bchan=32-46,48-62
hardhdlc=47

span=3,1,0,ccs,hdb3
bchan=63-77,79-93
hardhdlc=78

span=4,2,0,ccs,hdb3
bchan=94-108,110-124
hardhdlc=109

span=5,1,0,ccs,hdb3
bchan=125-139,141-155
hardhdlc=140

span=6,2,0,ccs,hdb3
bchan=156-170,172-186
hardhdlc=171

硬件配置：Intel(R) Xeon(R) CPU E5504 @ 2.00GHz 内存 2G
3张DE210E卡

麻烦告诉我，如果要并发150路，是否还需要提高硬件环境，或者需要怎样做，谢谢！
当时查看top值，负载以及cpu的使用率并不高。该机器只作媒体转换。

如果要并发150路，建议你用2台电脑。主要是I/o的带宽受限。

如果采用MG，即媒体接入用一台机器，然后sip中继指向到PBX，去处理话务是否可行。


或者您的意思是采用两台PBX，但这样不便控制。

可以用MG的方式,前端用2个asterisk做tdm->sip，再用一个asterisk做话务控制。

苗总：感谢您的回复，然后是我的MG跑的是90路，但依然有大量的报错信息如下：

这些错误是否由于I/O带宽受限引起的，还是其它原因，如果是I/O带宽受限了，请教如何可以提高I/O的吞吐率，该机器
目前只做MG使用。
万分感谢！
