[Disksim-users] Fwd: simulating RAID-4 with SSD

[Naser Heidari]

*Hi all,*
*
*
*for simulating RAID-4 by using SSD, i have changed ssd-iozone.parv file in
this way:*

instantiate [ ssd0x0 .. ssd0x3 ] as  SSD

# system topology
topology disksim_iodriver driver0 [
     disksim_bus bustop [
         ############## HBA 0 #############################
          disksim_ctlr ctlrHBA0 [
               disksim_bus busHBA0 [
                  ############## Flash-device Raid Controller
###############
                    ssdmodel_ssd ssd0x0 [],
     ssdmodel_ssd ssd0x1 [],
    ssdmodel_ssd ssd0x2 [],
     ssdmodel_ssd ssd0x3 []
               ]     # end of bus0
         ]        # end of HBA0
          ############ INSERT MORE HBA's ##############################
######
     ]           # end of bustop
]              # end of driver0 (and system topology)


*also i have changed logorg block in **ssd-iozone.parv**:*

disksim_logorg org0 {
   Addressing mode = Array,
   Distribution scheme = Striped,
   Redundancy scheme = Parity_disk,

   # vp - added more ssd elements
   devices = [ ssd0x0 .. ssd0x3 ],

   Stripe unit  =  128,
   Synch writes for safety =  0,
   Number of copies =  2,
   Copy choice on read =  6,
   RMW vs. reconstruct =  0.5,
   Parity stripe unit =  128,
   Parity rotation type =  1,
   Time stamp interval =  0.000000,
   Time stamp start time =  60000.000000,
   Time stamp stop time =  10000000000.000000,
   Time stamp file name =  stamps
} # end of logorg org0 spec

*Is there any other changes in .parv file or ssd.c, ssd.h and so on ???*
*or that's enough for simulating RAID-4 ???*
