Accusys ExaSAN SW-08 - Manual (Page 12)

1.3.4 Connecting the Private LAN
In addition to the ExaSAN PCIe network, all computers for the SAN must be connected to a private Ethernet
network (the Private LAN). Xsan MDC servers and clients use this network instead of the ExaSAN network to
exchange file system metadata. Connect each SAN client and MDC servers to two Ethernet networks: one private
subnet for the SAN metadata and a separate connection for directory service, intranet, and Internet traffic (the
Public LAN).
The steps below apply to the Private LAN only. We assume that the Public LAN is already in place.
1. Connect your workgroup host system #1 to the private LAN Ethernet switch with a CAT-5 cable.
2. Repeat Step 1 for host systems #2.
3. Connect the ExaSAN switch to the private LAN Ethernet switch with a CAT-5 cable.
The client and metadata controller computers need static (fixed) IP addresses for both public and private Ethernet
network connections. Don’t use DHCP to assign dynamic IP addresses to Xsan devices. We suggest that you use
the following ranges of IP addresses for Xsan private metadata network:
• IP address range: 10.10.10.1 to 10.10.10.254
• Subnet mask: 255.255.255.0
1.4 Connecting to a Power Source and Powering On
Before powering on, make sure that all cables and cords are properly installed and connected.
1. If not yet plugged into the wall electrical outlet, plug the power cord for the storage unit and the ExaSAN switch
to a power source.
2. Turn power on for the storage unit first by pressing the Power button. Proceed to the next step with switch
power. The Disk Status LEDs, which is the left column of 8 LEDs above the Power button, will not be active until
the switch is powered on.
