Glossary
SCSI Channel
A bus that uses SCSI protocol to move data to and from disks.
Selectable RAID Rebuild Rate
A selectable parameter that specifies how much time the controller devotes to rebuilding a failed
drive. A higher rebuild rate will speed the rebuilding of the array but may slow the performance of
the host operating system during the rebuild.
SMART Support (Self Monitoring Analysis and Reporting Technology)
A drive technology that reports its own degradation, enabling the operating system to warn the user
of potential failure.
SNMP
Simple Network Management Protocol, a standard for management network devices.Since
management framework requirements can use DMI and SNMP, both are provided with SRCU31.
SNMP Protocol
SNMP stands for Simple Network Management Protocol. The SNMP protocol describes the rules
by which a SNMP-managed device communicates with an SNMP management application.
Storage Console
The application used to configure RAID volumes via an html browser. This tool is used to set up
the RAID Levels, cache policies, rebuild rate and global hot spares of the controller.
Stripe
A stripe is interleaved data across multiple drives in an array. Data is sequentially stored in
allocated sizes across disks, based on the RAID level. Stripe size is the number of drives x the strip
size.
Variable Strip Size
Stripe size is the size of the logically contiguous data block recorded on all drives connected to the
controller. A variable strip size allows for the configuration of the stripe size. The strip size for a
volume can be configured to one of several sizes (4k - 128k depending on the RAID level). Note: a
two disk RAID level 1 volume will always have a 64k strip size.
