Hot-Pluggability

Hot-pluggability allows components to be removed and replaced without
powering down the MSA1000.
The following MSA1000 hardware components are hot-pluggable:
Hard Drives—Failed drives in fault-tolerant configurations can be replaced
without interrupting system operation. Data on the failed drive is restored
automatically to the replacement drive online.
Power Supply/Blower Assembly—Redundant power supplies allow you to
remove one power supply and replace it without interrupting system operation.
The assembly includes one variable speed blower for each power supply. If one of
the blowers in the assembly fails, the other blower automatically operates at a
higher speed. A blower can be removed and replaced without removing the
assembly.
MSA1000 Controller—If your system has two controllers and one controller
fails, you can remove the failed controller. See the HP StorageWorks 1000
Modular Smart Array Maintenance and Service Guide for specific limitations.
Fibre Channel I/O Module—The Fibre Channel I/O Module is a single-port,
hot-pluggable 1-Gb/2-Gb Fibre Channel device that includes a 2-Gb Small Form
Factor Pluggable Transceiver (SFP) port. This module can be removed and
replaced with other interconnect options, such as the MSA SAN Switch 2/8 or the
MSA Hub 2/3.
MSA SAN Switch 2/8—The MSA SAN Switch 2/8 is an optional, hot-pluggable
I/O device designed to replace the single port Fibre Channel I/O Module that
comes standard with the MSA1000. This switch includes 8-ports, featuring 2 Gb/s
full duplex non-blocking performance on all ports. One port is internal to the
switch, leaving 7 available external ports.
MSA Hub 2/3—The MSA Hub 2/3 is an optional, hot-pluggable I/O device
designed to replace the single port Fibre Channel I/O Module that comes standard
with the MSA1000. This hub provides an inexpensive and easy way for a
clustered pair of servers to access the storage controller (using an arbitrated-loop
configuration), without having to buy an external hub or switch. Two SFP ports
are presented to the user, while a third, internal port accesses the controller.
