6300 Systems

The following topics provide an overview of ftServer systems:

• “System Design” on page 1-1
• “System CRUs” on page 1-10
System Features
Stratus ftServer 2600, 4500, and 6300 systems contain redundant (duplexed)
components that process the same instructions simultaneously (in
lockstep
). If one of
the duplexed components fails, its partner continues operating, eliminating system
downtime and data loss.
Stratus failsafe software adds a layer of security to the lockstep technology, preventing
many software errors from resulting in outages. Software issues are captured,
analyzed, and reported to Stratus, allowing support personnel the ability to address
software problems before they recur. Stratus’ hardened device drivers further enhance
the reliability of the operating system environment on ftServer systems.
Optional support by the
Stratus ActiveService Network
(ASN) provides remote service
and incident management of the system by the Stratus Customer Assistance
Center (CAC) or your authorized Stratus service representative.
Many components of the ftServer systems are
customer-replaceable units
(CRUs),
which allow easy removal and replacement of faulty components by on-site personnel
with minimal training or tools. See “Description of System Components” on page 1-8
for more information.
System Design
Each ftServer 2600, 4500, and 6300 system is rack-mounted and consists of a chassis,
two CPU- I ⁄ O enclosures, a front panel assembly with a DVD drive and USB port, a
backplane assembly with an optional modem for connecting to the ASN network, and
peripheral components.
