No, what you did is perfectly fine.  Each channel natively supports 4 drives, so two channels simply allows you to connect up to 8 drives.  Some people feel setting up separate VD's on separate channels is advantageous (in theory, isolating data traffic between virtual disks), although I do not know what type of real-world advantage this would actually give you.  If it did indeed equate to some small advantage, then there may be some small advantage with a RAID 10 separating disks across the different channels, but this is unlikely to do much for you but make configuration and layout more confusing. My advice would be to simply leave it as is (unless someone else can speak to a real-world advantage of using multiple channels).
Please excuse this very basic questions. We have recently set up our Poweredge 2950 (an older model with 6 slots and Perc5/i). The machine will mostly be a file and SQL database server. We have opted to format the drives such that we have ONE big Raid 10 array over 4 disks with two hot spares. Partitions C and D are supposed to carry 2008 enterprise server and the data respectively. However, only after installing OpenManage, I became aware the machine has two Raid connectors. I am aware that most people would do a raid 1 on the first connector and a raid 5 (maybe 3 disks + 1 hot spare) on the second connector. Would anybody help me out and comment whether what we did was really stupid now and why so ? Or whether this is quite allright to leave one connector unused ? I would think our performance is suboptimal now. Or not ? 1000 thanks for anybodys patience with this real basic stuff. Please, a link to external resources where the two connectors are explained and their use is also quite allright. I just could not find anything ... Ingo
Very basic question about two connectors on Perc5/i
