RAIDWatch User’s Manual
SASL
SASL is the Simple Authentication and Security Layer, a
mechanism for identifying and authenticating a user login to a
server and for providing negotiating protection with protocol
interactions.
SCSI
Small Computer Systems Interface (pronounced “scuzzy”) – a
high-speed interface for mass storage that can connect computer
devices such as hard drives, CD-ROM drives, floppy drives, and
tape drives. SCSI can connect up to sixteen devices.
S.E.S.
SCSI Enclosure Services is a protocol used to manage and sense
the state of the power supplies, cooling devices, temperature
sensors, individual drives, and other non-SCSI elements installed in
a Fibre Channel JBOD enclosure.
S.M.A.R.T.
Self-Monitoring, Analysis and Reporting Technology – an open
standard for developing disk drives and software systems that
automatically monitor a disk drive’s health and report potential
problems. Ideally, this should allow users to take proactive actions
to prevent impending disk crashes.
SMS
The Short Message Service (SMS) is the ability to send and receive
text messages to and from mobile telephones. SMS was created and
incorporated into the Global System for Mobiles (GSM) digital
standard.
Spare
Spares are defined as dedicated (Local) or Global. A drive
designation used in RAID systems for drives that are not used but
are instead “hot-ready” and used to automatically replace a failed
drive. RAIDs generally support two types of spare, Local and
Global. Local Spares only replace drives that fail in the same
logical drive. Global Spares replace any drive in the RAID that
fails.
Stripe
A contiguous region of disk space. Stripes may be as small as one
sector or may be composed of many contiguous sectors.
