Service Processor (SP):
The SP on the Power blade is similar to the SP (sometimes called
“FSP”) on other POWER6-based systems. It contains firmware to manage the hardware on the
blade; the Power Hypervisor; and Partition Firmware (PFW).
System firmware:
As with other POWER6-based systems, this is the firmware on the SP (see
above).
I/O expansion card:
Sometimes called “daughter card.” An I/O adapter that fits into a PCIe or
PCI-X slot on the blade and allows connectivity to external I/O devices through the BladeCenter
midplane and I/O modules.
Combination Form Factor – Horizontal (CFFh) I/O expansion adapter:
A PCIe I/O adapter
that allows access to external resources through I/O bays 7 – 10 in BladeCenter H, and bay 2 in
BladeCenter S.
Combination I/O Form Factor – Vertical (CIOv) I/O expansion adapter:
A PCIe I/O adapter
that allows access to external resources through I/O bays 3 and 4 in both BladeCenter H and
BladeCenter S.
Combination Form Factor – Vertical (CFFv) I/O expansion adapter:
A PCI-X I/O adapter that
allows access to external resources through I/O bays 3 and 4 in both BladeCenter H and
BladeCenter S.
Adapter firmware:
The firmware on the I/O expansion cards on the blade.
Integrated Virtual Ethernet (IVE) ports:
Like other POWER6-based systems, the POWER6
blade includes 2 embedded Gigabit Ethernet ports on the system I/O bridge chip.
Host Ethernet Adapter (HEA)
ports: Another name for the IVE ports, more commonly used in
technical documentation.
Virtual I/O Server (VIOS):
The Virtual I/O Server is software that is located in a logical partition.
This software facilitates the sharing of physical I/O resources between client logical partitions
within the system.
Integrated Virtualization Manager (IVM):
A browser interface installed with VIOS. It provides
LPAR and virtualization management functions.
Virtual Ethernet adapter:
A virtual network adapter created in the Power Hypervisor that is part
of an LPAR’s hardware resources. On Power blade, IBM i cannot be assigned physical network
adapters.
Virtual SCSI adapter:
A virtual storage adapter created in the Power Hypervisor that is part of
an LPAR’s hardware resources. On Power blade, a Virtual SCSI (VSCSI) client adapter is
created in IBM i and a VSCSI server adapter in VIOS for storage virtualization.
Virtual Ethernet bridge:
A VIOS function that allows Layer-2 bridging of a Virtual LAN to an
outside physical LAN. It is a required on Power blade in order to provide both LAN console and
standard networking to IBM i.
Logical Unit (LUN):
A volume created on a SAN system that appears as a single disk device to
a server.
Disk Drive Module (DDM):
A physical disk unit in a SAN system.
SDDPCM (Subsystem Device Driver – Path Control Module):
A Multi-path I/O (MPIO) driver
for certain storage subsystems installed on top of VIOS.
RDAC (Redundant Disk Array Controller):
A Multi-path I/O (MPIO) driver for DS4000 or
DS5000, which is included with VIOS.
SAS (Serial-attached SCSI):
A storage access protocol, which is the next generation of the
[parallel] SCSI protocol.
DSM (Disk Storage Module):
A disk bay in the BladeCenter S, currently capable of supporting
six SAS or SATA drives. Two DSMs are supported in the BladeCenter S.

environment, see http://www.ibm.com/systems/i/advantages/v6r1/blades/index.html.
