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?

Should I expect problems? I'm confused. In the end, overall, which is best for a T100P (or even a TE405P) card? IDE or SCSI? Raid or No Raid? 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? Or even SATA based server? ----- Original Message ----- From: "Dana Nowell" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, July 22, 2004 11:57 AM Subject: Re: [Asterisk-Users] RAID affecting X100P performance... > In an article on IDE vs. SCSI I read that MTBF numbers for IDE were > frequently caculated at 8 hours on 16 hours off per day (assumes desktop > usage) but SCSI drives were calculated at 24hrs on per day.
