Chapter 1: Introduction 

   

1.1 About the QOS 8-Bay 

The    QOS    is    a    standalone    storage    array,    part    of    a    file-­‐based    workflow    involving    one    or   

more   users   and   a   single   centralized   storage   system.      The   extraordinary   power   and   versa-­‐
tility   of   the   QOS   is   one   of   the   key   features   of   this   product.      The   QOS   can   be   used   to   inte-­‐

grate   multiple   users   on   shared   storage   volumes   or   function   as   a   direct   attached   drive   ar-­‐
ray.      It   is   powered   by   a   multi-­‐core   processor,   which   is   housed   in   an   ultra-­‐quiet   and   shock-­‐
resistant   chassis.   

   
The   MDC   is   the   embedded   RAID   controller   housed   inside   in   the   QOS.      It   acts   as   a   server   

that   interacts   with   computers   connected   to   it   called   clients   and   grants   them   access   to   the   
RAID   storage   drives.      Read-­‐write   processes   sent   to   the   drives   can   be   shared   between   mul-­‐
tiple   clients   with   the   use   of   Rorke   HyperFS   SAN   management,   allowing   instantaneous   col-­‐

laboration    between    workstations    connected    directly    to    the    back    or    through    a    Fibre   
switch.         
   

1.2 Liability 

In   no   event   will   Ocean   Tides   Production   Ltd.      Be   liable   for   direct,   indirect,   special,   inci-­‐
dental,   speculative   or   consequential   damages   arising   from   the   use   or   inability   to   use   this   
product   or   documentation,   even   if   advised   of   the   possibility   of   such   damages.   In   particu-­‐

lar,   Ocean   Tides   Productions,   ltd.   Shall   not   have   liability   for   any   hardware,   software,   or   
data   stored   or   used   with   the   product,   including   the   costs   of   repairing,   replacing,   integrat-­‐

ing,   installing   or   recovering   such   hardware,   software,   or   data.   
   

1.3 Caution 

 

Do   not   use   any   other   power   cable   than   a   standard   120V   20A,   do   not   modify   any   of   

the   cables   or   connectors.   

 

Do   not   expose   the   QOS   to   water   or   excessive   moisture   and/or   humidity.   

 

Do   not   install   near   heat   sources   such   as   radiators,   heat   registers,   stoves,   and   other   

heat   producing   devices.   

 

Do   not   insert   any   objects   into   the   grates   on   the   front   and   back.      Blocking   any   of   the   

grates   may   cause   damage   to   the   unit.   

 

Do   not   apply   force   directly   to   the   HBA   interface   cards   on   the   back.   

 

Do   not   remove   drives   from   the   unit   while   it   is   running   unless   there   is   a   failed   drive.      
Drives   take   out   of   the   unit   while   powered   off   to   be   put   back   in   (ex   shipping)   must   

go   back   into   the   exact   same   slot   they   were   in   previously   before   it   is   powered   back   
up   –   all   drives   must   be   returned   before   the   RAID   is   powered   on.      

 

Do   not   use   any   other   model   of   hard   drives   than   the   exact   same   that   came   with   your   

QOS   system.      If   in   doubt,   check   with   QOS   Technical   Support.            

 

Be    careful    when    moving    the    QOS    unit    not    to    expose    it    to    excessive    impacts    and   

shocks.
