[Asterisk-Users] RAID/SCSI/IDE/SATA and a TE405P (or T100P) c ard. Should I expect problems?
Hello, We use all SCSI PCI card hardware RAIDs on all 4 of our production Asterisk servers. They all have Digium quad T1 cards and they all have from 2 to 4 T1s hooked up to them. We have had no noticable problems with dropped calls/poor quality. What are you looking to do with this system? what kind of traffic will be going through these 4 T1s?

I was anticpating putting a single Quad-Port TE405P inside a Dell PowerEdge, Dual 1.3ghz Processors, SCSI Hard Drive (No Raid). Was going to run 4 Full T1 PRI's into it, either all from 1 carrier, or 4 different carriers. Can/Should I expect problems (echo, dropped calls, poor quality, etc.)? Should I hunt down a high end IDE based Server?

[Asterisk-Users] RAID/SCSI/IDE/SATA and a TE405P (or T100P) card. Should I expect problems?
Not sure on load as of yet. We have a bout 80 customers right now, most with only 1 phone. 3-5 of them are small offices with 5-10 phones. Right now we have 3 PRI's and 1 Older Voice T1 (non PRI, 24 channels) going into a Cisco router, which then sends it via SIP to Asterisk. I'm wanting to phase out the Cisco as the TE405P cards are cheaper than the Dual Port VWIC cards for the Cisco. However, reading all these posts about hardware incompatibiliites and little issues with different hardware has gotten me a little concerned about this migration/changeover. IRQ's, poor quality controllers, dual processor's, raid vs ide, etc. etc. can all affect a call. If the server isn't just right, I could encounter issues. ----- Original Message ----- From: "mattf" <mattf@vicimarketing.com> To: <asterisk-users@lists.digium.com> Sent: Thursday, July 22, 2004 1:05 PM Subject: RE: [Asterisk-Users] RAID/SCSI/IDE/SATA and a TE405P (or T100P) card.
