The SuperTrak EX8650, EX8654, and EX8658 cards are designed to manage up
to 16 enclosures and up to 256 SAS or SATA disk drives (using SAS expanders).
If your system has fewer components, you might be surprised at the way
WebPAM PRO numbers your enclosures and drives. The following scenarios
illustrate some numbering examples.
Scenario 1: Virtual Enclosure – SGPIO
You install the SuperTrak card into an SGPIO enclosure. You attach a SAS data
cable between Port Ch1-4 and the enclosure’s backplane.
In WebPAM PRO, the SGPIO enclosure appears as Enclosure 1. The drives are
numbered 1 to 128.
If you attached a second SGPIO enclosure to Port Ch5-8, it would appear in
WebPAM PRO as Enclosure 10. The drives would be numbered 129 to 256.
Scenario 2: Virtual Enclosure – Host PC
You install the SuperTrak card into a Host PC. You attach SAS breakout cables
to Ports Ch1-4 and Ch5-8 and a SAS or SATA drive at the drive ends of each
cable.
In WebPAM PRO, the Host PC appears as Enclosure 1. The drives on Port
Ch1-4 are numbered 1 to 4. The drives on Port Ch5-8 are numbered 129 to 132.
This scenario also applies if you use Promise SuperSwap enclosures.
Scenario 3: External Enclosures – Daisy Chain
You install the SuperTrak card into a Host PC. You attach a SAS data cable
between Port Ch1-4 and a Promise VTrak J310s 12-drive JBOD enclosure. You
connect a second J310s enclosure to the first in a daisy chain.
In WebPAM PRO, the first JBOD enclosure appears as Enclosure 2. The drives
are numbered 1 to 12. The second JBOD enclosure appears as Enclosure 3. The
drives are numbered 13 to 24.
Scenario 4: External Enclosures – Parallel
You install the SuperTrak card into a Host PC. You attach a SAS data cable
between Port Ch1-4 and a VTrak J310s enclosure. You attach a SAS data cable
between Port Ch5-8 and a second J310s enclosure.
In WebPAM PRO, the first JBOD enclosure appears as Enclosure 2. The drives
are numbered 1 to 12. The second JBOD enclosure appears as Enclosure 10.
The drives are numbered 129 to 140.
Scenario 5: SAS Expanders
You install the SuperTrak card into a Host PC. You attach a SAS data cables
between Ports Ch1-4 and Ch5-8 and two SAS Expanders.
