iSCSI configuration 1 - Windows
Chapter 16.
2003 with QLogic QMC4052 HBA
This sample configuration shows how to connect logical drives configured on an IBM System
Storage DS3300 to a Windows Server 2003 running on an IBM BladeCenter HS21 with a
QLogic iSCSI Expansion Card for BladeCenter.
To be able to use the QLogic iSCSI Expansion Card for BladeCenter in an IBM BladeCenter
HS21, a BladeCenter Storage IO Expansion 3 (BSE3) was used that allows standard and
small formfactor daughter cards to be installed in addition to hard drives. The iSCSI HBA was
installed in the BSE3 in the slot that connects to module bays 3 and 4 of the BladeCenter
chassis. The decision to use module bays 3 and 4 was made to have dedicated network
equipment for the iSCSI traffic. That increases network stability and provides a safer SCSI
connection later to the host.
Nortel Layer 2/3 Gigabit Ethernet switches are installed in module bays 1, 3 and 4. Bay one,
that connects to the first onboard NIC of the blades, is used for the public network access.
Bay 3 and for that connects to an expansion slot on the blade and the BSE3 is used to
connect to the installed iSCSI HBA as well as in a later sample configuration to a regular
network card to handle iSCSI traffic over an software initiator instead of hardware initiation.
A basic network diagram that provides an overview of the cabling between the components is
shown in 16.1, "Network configuration" on page 342.
