Hardware Specifications and Features
3.6
Hot-Plug Disk Drive Support
This feature allows for the ability to remove and replace drives while I/O activity is taking
place, provided that both the hard disk drive and backplane fully support hot-swap,
without interruption of operations on any other drives. It supports the hot plug of new
drives in non-intelligent enclosures as detailed in
3.7
Auto-detection of Hot-Plug Disk Drives in a Non-
Intelligent Drive Enclosure
This feature allows the use of non-intelligent disk enclosures (requires truly hot-pluggable
disk drives and backplane connectors) as though they were intelligent enclosures. This
feature is configurable and allows the user to set up non-intelligent enclosures to detect
the insertion or removal of hot plug disk drives and report the event to the RAID
firmware. The RAID configuration is automatically updated to the new configuration.
Access this feature through the
Advanced Setup
menu of Storage Console.
3.8
RAID Controller Drive Limitations (Host, Array,
Logical, and Physical)
The following are limitations assuming the following:
•
Four SATA ports
•
Cabling that meets SATA specifications 1.0
Physical drives
are limited by the number of ports (four) on the RAID controller. Each
physical drive must be connected to one of the SATA ports. The maximum number of
array drives
is two. A RAID array drive requires a minimum of two hard disk drives (or
logical drives). Therefore the maximum RAID array drive limitation for the SRCS14L
controller is the physical drive limit divided by two.
Each RAID array drive (up to two) can contain up to a maximum of two
host drives
. This
means that the SRCS14L controller has a maximum limitation of four host drives. Also,
each array drive must have at least one host drive. A host drive can only be associated
with (or reside on) a single array drive.
