NICs and a separate network infrastructure (cables, switches, and MPX200 blades). HP recommends
using separate target ports.
Microsoft MPIO allows the initiator to log in to multiple sessions to the same target and aggregate
the duplicate devices into a single device exposed to Windows. Each session to the target can be
established using different NICs, network infrastructure, and target ports. If one session fails, another
session can continue processing I/O without interrupting the application. The iSCSI target must
support multiple sessions to the same target. The Microsoft iSCSI MPIO DSM supports a set of
load-balance policies that determine how I/O is allocated among sessions. With Microsoft MPIO,
the load-balance policies apply to each LUN individually.
The Microsoft iSCSI DSM 2.x assumes that all targets are active/active and can handle I/O on
any path at any time. There is no mechanism in the iSCSI protocol to determine whether a target
is active/active or active/passive; therefore, the MPX200 supports only multipath configurations
with the P6000 EVA with active/active support. For more information, see the following:
details the differences between Windows Server 2008 and Windows Server
2003.
