Facilis TX16 EXPANSION CHASSIS
– After connecting and adding a
Facilis
TX16 Expansion Chassis
to the TerraBlock Server, you will see additional groups
(3, 4, etc), depending on the number of TX16 Expansion Chassis you have
added.
Refer to the
Facilis TX16 Expansion Chassis Setup Guide

information on the Facilis TX16 Expansion Chassis
DynaRAID –
The designations of “Mirror”, “RAID5”, “RAID50”, “RAID51”, or “----“
(unprotected) are listed for each volume, according to the state of protection on the
specific volume. This represents the current state of protection selected when first
creating the volume.
Mirrored, RAID5 and unprotected volume protection can be changed at any time
without losing data. RAID50 and RAID51 cannot be changed.
In the case of an
individual physical drive failure, RAID5, RAID50, RAID51 and Mirrored
DynaRAID settings will maintain the data integrity of virtual volumes.
Mirror
indicates that the data on the volume is being mirrored. Every
file written to a disk drive is written again to another drive and in the
case of an individual physical drive failure the necessary mirror data
takes over. A volume may be mirrored when created, and the
protection removed or changed to RAID5 at any time.
RAID5
indicates that the volume is being protected by RAID5 parity
data. Information about the primary data stored on the virtual volume
is calculated, compressed and saved back onto the physical drive set.
If an individual physical drive failure occurs, the necessary RAID5 data
is decompressed and used in place of the missing primary data. A
volume may be protected with RAID5 when created, and have the
protection removed or changed to Mirrored at any time.
----
indicates that the volume is not protected. A volume may be
unprotected when created utilizing a Single group of drives (Group 1).
RAID5 or Mirror protection can be added at any time. If an individual
physical drive failure occurs,
all data
on an unprotected virtual volume
will be lost.
RAID50
indicates that the virtual volume spans multiple Facilis
devices and is being protected with RAID50 parity. The data and
DynaRAID RAID5 parity data is striped across multiple Facilis devices.
The Facilis device can be an additional TerraBlock Server or a Facilis
TX16 Expansion Chassis.
If an individual physical drive failure occurs, the necessary RAID5 data
is decompressed and used in place of the missing primary data. If one
of the individual Facilis devices (TerraBlock Server or TX16 Expansion
Chassis) containing the RAID50 data becomes unavailable, the RAID50
volume will also become unavailable for use on all clients.
RAID50 volumes require a Windows 7 or Windows 10 TerraBlock
Server and must be created on the TerraBlock Server itself. RAID50
DynaRAID protection is set at volume creation time and cannot be
changed.
