DS2100 connection

[Lacrosse]

If I have 2 connections running from one dual port SCSI controller to the same DS2100 and the SCSI ID's on each interface on the card are the same, should I be Okay because the internal path is unique on each connection?? i.e. 10/40/7 and 10/41/7 (hypothetically) I know you can change them just wanted to know if that was correct

You should be OK I have seen setups like yours
work fine.

There is nothing wrong with your setup. We have soemthing similar on our rp5450(L2000) servers at work.

Um, guys? This won't work with a DS2100 chassis. This is the little 4-drive unit, with no "split bus" mode. This would work fine with a DS2300 14-drive unit, which offers a split-bus option.

Either go with two DS2100s, on two HBAs (for best HA), and mirror between the chassis, or use the DS2300 in split-bus mode for the HA mirroring function.

I suppose you could change the initiator ID from 7 to 6 on one port of the dual port card, and make this work (presuming that the IDs can be changed, which I believe they can). But you have a "BA" (barely available) solution. Single points of failure would be the card, the SCSI bus, and the chassis/power supplies/etc. Essentially, everything.

For best HA, use seperate SCSI cards, and seperate chassis, and mirror between the seperate SCSI domains.
