1.4.1 RAID Configuration
ExpressSAS RAID and ThunderStream SC storage controllers provides the capability to configure disk storage
into RAID groups or Hot Spare drives.
Use the ATTO ConfigTool to set up RAID groups on
your ExpressSAS RAID or ThunderStream SC
storage controller in one of the following RAID levels:
• JBOD
RAID Level 0
RAID Level 1
RAID Level 4
RAID Level 5
RAID Level 6
RAID Level 10
ATTO DVRAID™ (parity redundancy optimized
for digital video environments: refer to Setting up
DVRAID on page 18).
ATTO DVRAID is set up automatically by the
ExpressSAS RAID or ThunderStream SC storage
controller firmware. All other types of RAID require
customized input.See
Exhibit 1.4.1-1
.
Each RAID group may be divided into one or more
partitions; each partition appears to the host operating
system as a virtual disk.
You may use the RAID Command Line Interface page
from the
RAID CLI
tab in the ATTO ConfigTool to set
up or modify various parameters (Refer to
Appendix A
). However, the ATTO ConfigTool
procedures listed in this chapter are the preferred
procedures for setting up RAID configurations for
ExpressSAS RAID and ThunderStream SC storage
controllers.
Note
The ConfigTool screens are similar for all
operating systems.
