Installing  a  hard  disk  drive 
Locate  the  documentation  that  comes  with  the  hard  disk  drive  and  follow  those 
instructions  in  addition  to  the  instructions  in  this  chapter. 
Important:  Do  not  install  a  SCSI  hard  disk  drive  in  this  server;  install  only  SAS  hard 
disk  drives. 
The  following  notes  describe  the  type  of  hard  disk  drive  that  the  server  supports 
and  other  information  that  you  must  consider  when  installing  a  hard  disk  drive: 
v  The  server  3.5-inch  models  support  six  slim  3.5-inch  hard  disk  drives  installed  on 
Ultra-Slim  hard  disk  drive  trays  for  3.5-inch  drives.  For  a  list  of  supported  3.5-inch 
hard  disk  drives,  see  http://www.ibm.com/servers/eserver/serverproven/compat/
us/. 
v  The  server  2.5-inch  models  support  eight  2.5-inch  hot-swap  hard  disk  drives 
installed  on  Ultra-Slim  hard  disk  drive  trays  for  2.5-inch  drives.  For  a  list  of 
supported  2.5-inch  hard  disk  drives,  see  http://www.ibm.com/servers/eserver/
serverproven/compat/us/.
 
v  All  hot-swap  drives  in  the  server  should  have  the  same  throughput  speed  rating. 
Mixing  hard  disk  drives  with  different  speed  ratings  will  cause  all  drives  to 
operate  at  the  lower  throughput  speed. 
v  The  ID  that  is  assigned  to  each  bay  is  printed  on  the  front  of  the  server. 
The  following  illustrations  show  how  to  install  a  hot-swap  hard  disk  drive.
