Mixing AT-FCX and ESH2 shelves on the FAS3000 Series filerCan DS14mk2-AT and DS14mk2-FC shelves be mixed in the same loop?Can AT-FCX and ESH2 modules exist in the same loop?Can ESH, ESH2, and ESH4 modules exist in the same loop?Can AT, AT-FC2, and AT-FCX modules exist in the same loop?Can IOM3 and IOM6 modules exist in the same storage stack?Can IOM modules be mixed with AT-FCX?What cables do I need to connect my disk shelves?
ATA storage uses the AT-FCX modules. Fibre Channel storage uses the LRC, ESH, ESH2 or ESH4 modules. SAS storage uses IONetApp storage controllers:
Note: Always consult the Systems Configuration Guide to ensure that the shelf module is supported in the storage appliance's v
The Data ONTAP System Configuration Guide (http://now.netapp.com/NOW/knowledge/docs/hardware/NetApp/syscfg/) contains additional information on the maximappliance.
Adding Expansion Shelves to the FAS270The FAS270 Storage Appliance has some specific requirements when mixing Fibre Channel and ATA drives:
If no expansion shelf is attached to port 0b on the FAS270, either a DS14mk2-FC (with ESH2/ESH4 modules) or a DS14mk2If a DS14mk2-FC expansion shelf with ESH2 or ESH4 modules has been attached to 0b on the FAS270, a DS14mk2-AT shelfIf a DS14mk4-FC expansion shelf with ESH4 modules has been attached to 0b on the FAS270, a DS14mk2-AT shelf with AT-If a DS14mk2-AT expansion shelf with AT-FCX modules has been attached to 0b on the FAS270, neither a DS14mk2-FC sheladded.

Mixing LRC with ESH, ESH2, ESH4, or AT-FCX in the same loopThe LRC module is supported in the DS14 and DS14mk2-FC shelf. However, shelves containing LRC modules cannot be in the scontaining LRC modules cannot be in the same FC-AL loop with shelves containing AT-FCX modules.
Mixing ATA and Fiber Channel in the same loopYou cannot mix DS14mk2-AT and DS14mk2-FC disk shelves in the same loop. Therefore, you cannot have LRC/ESH/ESH2/ESH4
Mixing IOM3 and IOM6 in the same storage stackThe IOM3 module is supported in the DS4243 shelf, and the IOM6 is supported in the DS2246 shelf. These two modules are nobe cabled together in the same storage stack, i.e. connected to the same SAS adapter on the storage controller.
Modules Supported in Each type of ShelfThe following chart shows which modules can be used in the various shelf types:
LRC ESH ESH2 ESH4 AT-FC AT-FC2 AT-FCX IOM3 IOM6
DS14 X X
DS14mk2-FC X X X X
DS14mk2-AT X X X
DS14mk4-FC X
DS4243 X
DS2246 X
Note: Use the Systems Configuration Guide to verify the shelf modules are supported in the storage appliance's version of Data
ESH / ESH2 / ESH4 CompatibilityESH, ESH2, and ESH4 modules may all be mixed in the same loop. All three modules may be used in the DS14-mk2 shelf. How
Only one type of I/O module can exist within a single shelf.ESH4 modules cannot be used in the DS14 shelf.ESH and ESH2 modules cannot be used in the DS14mk4-FC shelf.If ESH4 modules are mixed in the same loop as ESH and/or ESH2 modules, the loop cannot operate at 4 Gbps.Note: To achieve the 4Gbps throughput, it is advisable to configure the FC-AL loop to contain only ESH4 modules in DS14mIf ESH2 and/or ESH4 modules are mixed in the same loop as ESH modules, the loop can operate at 2 Gbps if all shelves in thconditions are not met, the loop will operate at 1 Gbps.Note: If the shelf speed needs to be changed from 1 Gbps to 2 Gbps on the DS14mk2-FC or DS14mk4-FC shelf, the shelf musense the loop speed only at power-up.To mix ESH and ESH2 in the same loop, the ESH modules must be running FW94 or later, and the ESH2 modules must be r
If used in thefirst shelf, anX6529-R6 isneeded to makethe IN portoptical (LC). An X6539-R6SFP (4 Gb) mayalso be used,but the SFP willonly operate at2Gbps.
