5 iSCSI or iSCSI/FCoE configuration rules and guidelines
This chapter describes the iSCSI configuration rules and guidelines for the HP P6000 iSCSI and
iSCSI/FCoE modules.
iSCSI or iSCSI/FCoE module rules and supported maximums
The iSCSI or iSCSI/FCoE modules are configured in a dual-controller configuration in the HP
P6000. Dual-controller configurations provide for high availability with failover between iSCSI or
iSCSI/FCoE modules. All configurations are supported as redundant pairs only. iSCSI connected
servers can be configured for access to one or both controllers.
HP P6000 Command View and iSCSI or iSCSI/FCoE module management
rules and guidelines
The HP P6000 Command View implementation provides the equivalent functionality for both iSCSI,
iSCSI/FCoE, and Fibre Channel connected servers. Management functions are integrated in HP
P6000 Command View.
The following are the HP P6000 Command View rules and guidelines for the iSCSI or iSCSI/FCoE
modules:
•
Requires HP P6000 Command View for array-based and server-based management
•
HP P6000 Command View manages the iSCSI or iSCSI/FCoE modules out of band (IP) through
the iSCSI or iSCSI/FCoE controller management IP ports. The HP P6000 Command View
application server must be on the same IP network and in the same subnet with the iSCSI or
iSCSI/FCoE module's management IP port.
•
The iSCSI or iSCSI/FCoE module iSCSI and FCoE Initiators or iSCSI LUN masking information
does not reside in the HP P6000 Command View database. All iSCSI Initiator and LUN
presentation information resides in the iSCSI and iSCSI/FCoE modules.
•
The default iSCSI Initiator EVA host mode setting is Microsoft Windows. The iSCSI initiator
for Apple Mac OS X, Linux, Oracle Solaris, VMware, and Windows 2008 host mode setting
is configured with HP P6000 Command View.
NOTE: Communication between HP P6000 Command View and the iSCSI modules is not secured
by the communication protocol. If this unsecured communication is a concern, HP recommends a
confined or secured IP network within a data center for this purpose.
HP P6300/P6500 EVA storage system software
The iSCSI and iSCSI/FCoE modules are not supported with HP P6000 Continuous Access.
Fibre Channel over Ethernet switch and fabric support
The iSCSI/FCoE modules provide FCoE target functionality. This enables server side FCoE
connectivity from Converged Network Adapters (CNAs) over 10 GbE lossless links and converged
network switches to the HP P6000 to realize end-to-end FCoE configurations. A simplified example
is illustrated in
Figure 22 (page 79) . HP P6000 Command View supports the iSCSI/FCoE module’s
FCoE LUN presentations while simultaneously servicing Fibre Channel and iSCSI hosts. The
iSCSI/FCoE modules support simultaneous operation of iSCSI and FCoE on each port.
The iSCSI/FCoE modules are supported with HP B-series and C-series product line converged
network switch models.
