RAID Level
|
RAID
0, 1, 1E, 5, 6, 10, 50, 60 Any combination of these RAID levels
can exist at the same time ;
Configurable
RAID stripe size: 64K, 168K, 256K, 512K and 1MB stripe size
per disk
Background
task priority tuning: adjustment of minimum I/O reserved for
server use during all background tasks
|
Hot spares |
Multiple global
or designated dedicated hot-spare drives with revert options
|
Max LUNs per subsystem
|
256 in any
combination of RAID levels and array types
|
Max LUNs per array
|
32 logical
drives (LUNs); Supports LUN Carving
by allowing an array to be divided into multiple logical drives;
RAID level, stripe size, sector size and cache policy can be
configured per LUN. Supports out of order logical drive deletion
and re-creation
|
Max LUNs per Target ID
|
Up to 256,
depending on host side driver and operating system
|
LUN Masking
and Mapping
|
Supports multiple
hosts
|
Disk data
formats
|
Supports Disk
Data Format (DDF) for industry wide standardization and drive
roaming between VTrak systems |
Background
Activities
|
Media Patrol;
Background synchronizing; Foreground initialization; Rebuild;
Redundancy Check; SMART condition pooling;

|
RAID Robustness
|
Physical
Drive Error Recovery: PDM (Predictive Data Migration): Replace
un-healthy disk member in array, and keep array on normal status
during the data transition between healthy drive and replaced
drive, Bad Sector Mapping, Media Patrol, SMART, Hard/Soft Reset
to recover drive from bad status, drive Power-control to recover
a drive from hung status. Array Error Recovery: Data recovery
from bad sector or failed drive for redundant RAID, RAID 5/6
inconsistent data Prevent (Write Hole Table), Data content Error
Prevent (Read/Write Check Table) NVRAM event logging
