Multi-Tiered Storage

Titan SiliconServer
AT-14 and AT-42 Storage Subsystem
The AT-14 storage subsystem can support
Tier 3
(7,200 RPM) and
Tier 4
(5,400 RPM) PATA
disks, where each storage enclosure can house up to 14 PATA disks per enclosure.
The AT-42 storage subsystem supports
Tier 4
storage (5,400 RPM PATA disks). Each storage
enclosure can house up to 42 PATA disks per enclosure.
Neither the AT-14 nor the AT-42 storage enclosure support cascading, so each enclosure houses
it is own RAID controller. Each enclosure supports a single RAID controller, and each RAID
controller supports dual FC host ports.
Note:
This section describes how to configure the AT-14 and AT-42 storage
systems. For instructions on how to define IP parameters, refer to the
AT-14
User Manual
or the
AT-42 User Manual
.
Storage Characteristics
The AT-14 and AT-42 storage enclosures use PATA disk technology and hardware RAID
controllers, which provide complete RAID 5 functionality and tolerance of single disk failures.
System Drives
System Drives are the basic storage element used by the Titan SiliconServer. A System Drive
comprises a number of physical disks. The size of the System Drive depends on the number of
disks and their capacity. The AT-14 and AT-42 RAID controllers support RAID 5. Each System
Drive has an identifying number (ID), which is unique to the Titan SiliconServer.
The
AT-14 User Manual
and
AT-42 User Manual
refer to System Drives as “volumes” (or “logical
volumes”). These should not be confused with the file system volumes used by the Titan
SiliconServer.
Note:
Throughout this section, a “Volume” is equivalent to a “System Drive”.
