Terminology Used In This Document
The following terminology is used in this document.
chassis |
The Sun Blade 6000 Modular
System chassis. |
CMM |
Chassis Monitoring Module. An Integrated Lights Out Manager component of the Sun
Blade 6000 Modular System used to access and manage servers, NEMs and storage
modules in the chassis. |
multipath |
This is a dual path connection from a host
to the storage module. Provides two paths to the storage components in the
storage module for failover. Path failover is managed through REM firmware when you
create logical drives using the REM firmware utilities. |
NEM |
Network Express Module. A networking I/O
component that plugs into a Sun Blade Modular System chassis. The chassis contains
two NEM slots: NEM 0 and NEM 1. |
REM |
A RAID Expansion Module. Also referred
to as a Host Bus Adapter (HBA), or an initiator. Is installed in
a server module and acts as an interface between the host and connected
storage. Supports the creation of RAID volumes on connected storage. Provides disk management
and monitoring of connected storage. |
SAS–2 |
Serial Attached SCSI version 2. Supports up to 6
Gb/s data transfer rate. The combination of SAS-2 devices, such as REMs, NEMs
and storage modules inside the chassis creates a SAS–2 domain connecting shared storage to
servers. Access to the chassis SAS-2 domain is managed by the CMM. |
SAS-2 NEM |
Any
Network Express Module that supports SAS–2 connectivity. Only NEMs that support SAS-2 can
be used with the Sun Blade Storage Module M2. For example, the Sun
Blade 6000 Virtualized Multi-Fabric 10GE NEM M2. |
SAS target |
A device containing logical units and
target ports that receives requests from, and responds to, an initiator. An example
of a target device is a hard disk. Other terms used to describe
a SAS target are “device” and “end device.” |
SATA |
Serial ATA (or Serial Advanced Technology
Attachment). Supports up to 1.5Gb/s data transfer rate for SATA and 3Gb/s for
SATA-II. SATA devices are single port/single path. |
server module |
A Sun Blade server module that fits
in the Sun Blade 6000 Module System. Server modules use storage in the
storage module. Might also be known as a “blade” or a “server blade”. |
single path |
This
is a single path connection from a host to the storage module
(for example, if there is only one NEM in the chassis, or the
target device is SATA). No path failover is available. |
storage module |
The Sun Blade Storage Module
M2. Might also be known as a “disk module” or a “disk blade”. |
zoning |
Zoning
in SAS-2 is a mechanism to manage large SAS topologies. The CMM Sun
Blade Zone Manager is used to assign storage resources on a per-server basis
in the chassis SAS-2 domain. Refer to the SAS-2 specification for more details. |
