802.1x network OOB to enable OOB SW updates, inventories, remote
diagnostics, etc.
A standards initiative for representing out-of-band management capability for computer
systems. It is a secure, web-services based successor to ASF.
Industry-standard specification for network alerting in operating system-absent
environments
TXT allows for secure management (via TPM) and measured launch of VMM, as
well as teardown of secrets in unexpected reset case. TXT support provided in
select Intel processors.
VT-d is a chipset technology that virtualizes directed I/O
Together, TXT and VT-d may be used to support verified launch of a known trusted VMM
that also may protect VMs from accessing each other's memory.
Computrace agent support standard
Product can be oriented as a tower (in addition to desktop orientation)
Implementation of the industry standard ATA Security feature set. When enabled, it
prevents software access to user data on the drive until one or two user-defined
passwords are provided.
Drive Protection System
A diagnostic hard drive self test. It scans critical physical components and every
sector of the hard drive for physical faults and then reports any faults to the user.
Running independently of the operating system, it can be accessed through a
Windows-based diagnostics utility or through the computer's setup procedure. It
produces an evaluation on whether the hard drive is the source of the problem and
needs to be replaced.
The system expands on the Self-Monitoring, Analysis, and Reporting Technology
(SMART), a continuously running systems diagnostic that alerts the user to certain
types of failures.
Allows hard drives to monitor their own health and to raise flags if imminent failures were
predicted
Predicts failures before they occur. Tracks fault prediction and failure indication
parameters such as re-allocated sector count, spin retry count, calibration retry
count
By avoiding actual hard drive failures, SMART hard drives act as "insurance"
against unplanned user downtime and potential data loss from hard drive failure
IOEDC: I/O Error Detection Circuitry
Detects errors in Read/Write buffers on HDD cache RAM
Interface in F10 setup for all dc7900 platforms provides confirmation of SMART IV
support.
