IBM System Storage DS3500: Introduction and Implementation Guide
4.1 DS3500 controller connectors
In this section we describe the various connectors that are located on the rear panel of each
of the four DS3500 controller models and the EXP3500 enclosure.
4.1.1 DS3500 controller with standard port configuration
Figure 4-1below shows the rear panel of a DS3500 controller with the standard port layout.
Figure 4-1 The rear panel of a DS3500 controller
From the left, the ports are:
A serial port - This port is reserved for use by IBM Service personnel only.
Two Ethernet management ports labelled 1 and 2 for Out-Of-Band (OOB) management.
SAS Host Ports labelled 1 and 2: these are two SAS 2.0 ports for host-side connections.
The DS3500 host ports are each a x4 multilane, 6 Gbps universal mini-SAS port.
The blank space on the rear panel is where the additional host ports on one of the optional
host adapter cards would be located. You can install one of three different types of optional
host adapter cards if you need additional SAS host port support or concurrent host
connectivity with either SAS and FC, or SAS and iSCSI.
The port on the extreme right is a x4 multilane mini-SAS port for connecting to EXP3500
drive expansion enclosures.
Below SAS ports 1 and 2 there is a 7-segment numeric LED display that provides information
about enclosure identification and diagnostics. The functions of this and the other status
LEDs located on the rear panel will be described in more detail in the Chapter 14,
“Administration - Support” on page 337.
4.1.2 DS3500 controller with optional SAS host port adapter
Figure 4-2 shows the rear panel of a DS3500 controller with the optional SAS host port
adapter installed. In addition to the standard ports described in section 4.1.1, “DS3500
controller with standard port configuration” on page 90, the optional SAS host port adapter
adds an additional two SAS 2.0 host ports for a total of four per controller.
