JBOD/RAID Configuration
The SurfRAID TRITON Mini supports JBOD and RAID configuration.
Maximum SATA Mode Supported:
The 4 SATA drive channel can support up to SATA ll, which runs up to 300MB/s.
NCQ is a command protocol in Serial ATA that can only be implemented on na-
tive Serial ATA hard drives. It allows multiple commands to be outstanding within
a drive at the same time. Drives that support NCQ have an internal queue where
outstanding commands can be dynamically rescheduled or re-ordered, along
with the necessary tracking mechanisms for outstanding and completed por-
tions of the workload. SurfRAID TRITON Mini allows user to choose the SATA
Mode: SATA150, NCQ, SATA300, NCQ.
Disk Capacity Truncation Mode:
This SurfRAID TRITON Mini uses drive truncation so that drives from differing
vendors are more likely to be able to be used as spares for each other. Drive
truncation slightly decreases the usable capacity of a drive that is used in
redundant units.
Multiples Of 10G : If you have 120 GB drives from different vendors;
chances are that the capacity varies slightly. For example, one drive might be
123.5 GB, and the other 120 GB. This drive Truncation mode
Multiples Of
10G uses the same capacity for both of these drives so that one could re-
place the other.
Multiples Of 1G: If you have 123 GB drives from different vendors; chances
are that the capacity varies slightly. For example, one drive might be 123.5
GB, and the other 123.4 GB. This drive Truncation mode
Multiples Of 1G
uses the same capacity for both of these drives so that one could replace
the other.
No Truncation : It does not truncate the capacity.
