SAS Connections and ID Numbers

The table below correlates the ranges of Enclosure IDs and Physical Drive IDs, that appear in the WebPAM PRO interface as a result of the data connections you make.

* A virtual enclosure involves physical drives attached directly to the SuperTrak controller or a connection to an SGPIO backplane.

You can attach up to 128 SAS or SATA drives on each SAS port using SAS expanders.

The SuperTrak EX8650 and EX8650A 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.
