Installing The Hba Card; Figure 15: Z2M Duo Port Card - Accusys ExaSAN A08S3-PS User Manual

Note
The hard drives in a RAID system should match in size and speed. All
drives in an array should be identical models with the same firmware
version.

3.1.2 Installing the HBA Card

Before the ExaSAN A08S3-PS is ready to be connected and powered on, you must install the
HBA card in the workgroup client system. The HBA card is compatible with PCIe x4, x8, and
x16 slots. If a choice is given, use the fastest PCIe slot available. Although the HBA card is
compatible with both PCIe 2.0 and 3.0 standards, only the latter is recommended for best
performance.
Caution
PCIe slots on some motherboards are for graphics cards only. Check
with the motherboard vendor for compatibility.
Follow these steps to install the card in each host system:
1. Make sure that the client system is turned off.
2. Open the client system's outer casing cover, check with your vendor documentation for
instructions if necessary.
3. The Port closer to PCIe logo is the SAN port, away from PCIe logo is the DAS port.

DAS port: Enable for RAID (Direct-Attached Storage A08S3-PS) mode.

SAN port: Enabled for switch (SAN) mode.
