Chapter 2: Hardware Installation
IMPORTANT!
For systems operating in Windows® 2003 server, and in the event of single-controller
failure, a logical drive is accessed via the host IDs managed by the alternate controller. The host IDs
and port IPs do not failover to the remaining controller. In this case, MPIO driver is necessary for path
redundancy and controller failover.
High Availability IP SAN with Port Trunk (Remote Replication-Enabled)
Component
Description
SAN Storage System
Redundant controllers with eight host ports
HBA
iSCSI initiators, preferably PCIe TOE (TCP/IP offload engine) capable
cards
GbE Cables
GbE network cables; port trunking marked in orange rectangles
GbE Switch
Ports divided into 2 virtual LANs. Both controllers are linked to both
virtual LAN zones.
Software
MPIO to manage the fault-tolerant paths with failover/failback and load
balance capabilities. Use MPIO multipathing software for the operating
system to identify the alternative paths to the same logical drive.
