Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-scsi@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org Hello, I wonder is that possible to configure disks from both channels to work in one array in Adaptec 3210S? Also, how many discs can I put to a channel and avoid decreasing performance? I think, if modern disk is able to transfer 30 Mb/s only 5 disks can be put to one channel, so 10 disks is practical limit for 2-channel Ultra160 controller. But it is only an idea, what does follow from the experience? Also, I guess there are no SCSI 320 RAID controllers?
