SCSI Channel

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.
