IBM Flex System V7000 Storage Node Introduction and Implementation Guide
12.1  Host configuration overview
In this section we provide an overview of connectivity between servers (hosts) and storage 
with the primary focus on how to configure the hosts.
A host system, as defined here, is an open-systems computer that is connected to storage 
through LAN or SAN switches, using either Fibre Channel (FC), iSCSI or FCoE protocols. In a 
IBM Flex System a host is also called a compute node.
IBM Flex SystemCompute nodes are available with either Intel Xeon or IBM Power7 
microprocessors. These Compute nodes use integrated network ports or optional network 
adapters to connect to external devices through the switches or pass-thru modules that are 
installed in the chassis. 
The following types of Compute nodes are available for IBM Flex Systems:
��
IBM System x: These Compute nodes come with Intel Xeon microprocessors and provide 
the function, reliability, and performance of the X-Architecture® systems in a 
small-form-factor design. They support a variety of Microsoft Windows, Linux, and 
VMware operating systems.
��
IBM Power Systems: These Compute nodes come with IBM Power7 microprocessors and 
provide the function, reliability, and performance of the Power7 systems in a 
small-form-factor design. They support a variety of AIX, Linux, and IBM System i® 
operating systems.
For more information about nodes, refer to IBM Flex System InfoCenter: 
This chapter covers the following operating systems and protocols:
��
Windows on IBM X-Architecture Compute nodes
– Fibre Channel (FC)
– iSCSI
– FCoE
��
VMware on IBM X-Architecture Compute nodes
– Fibre Channel
– iSCSI
��
AIX on IBM Power Systems Compute nodes
– Fibre Channel (FC)
��
LINUX on IBM X-Architecture Compute nodes
– a short introduction
This chapter focuses on Windows, VMware, AIX and Linux. If you attach any other hosts, for 
example, IBM System i, then you can find the required information in the IBM Flex System 
V7000 Storage Node Information Center at the following address:
