Pardon the IBM-terminology -- I have an N3600 A20 (ONTAP 7.3.1) and have acquired two EXN4000's to expand our storage capacity.
The N3600 A20 is currently configured as Active/Active with the existing set of 20 SAS disks.
I'm reading through the documentation on NOW[1] on hot-adding shelves and am running into a few questions:
- Is the EXN4000 the same as the DiskShelf14mk4? - How do I know if I have ESH2/ESH4 modules or LRC or ESH modules?
Also, the NOW documentation[1] refers to the Data ONTAP 7.3 Active/Active Configuration guide for hot-adding of shelves since we are using an Active/Active setup. I presume these are the insructions I need to use and not the normal hot-add instructions[1].
Anything else of note I should be aware of?
Thanks, Ray

- Is the EXN4000 the same as the DiskShelf14mk4? - How do I know if I have ESH2/ESH4 modules or LRC or ESH modules? Based on your questions, I suspect it is the same. Looking at the back of the disk shelf, there are two modules. One on the top and one on the bottom.
If there is any combination of DB9 and/or SC-fiber connector, then you have a LRC If there is any combination of HSSDC2 and/or LC-fiber based connector, then you have an ESH (it also say ESH in the corner, and you will notice a terminator switch between the input/ouput) If you see two SFP boxes with two LED between them and a 2Gb led, then you have ESH2 (I believe it also say ESH2 in the corner) If you see SFP boxes with no LEDs between them, a 2 & 4 Gb LED and also a 1Gb and ELP LED, then you have a ESH4. It also has a round plug (looks like 1/8 DIN) for a serial connection(IOIOI)

Knowing both N-Series and NetApp original one :-) I think I can answer. The N3600-A20 is a 2050 cluster. EXN4000 is the same as DS14MK4 (the "4" in the EXN4000 name stands for 4 Gbps). You have to find on the shelf two SFP (Gbic) connector plugged on the IN port of the two ESH4 controller. After all in the center of the shelf you have a selector that permit you to switch the backend speed from 1 to 4 Gbps (if limits to 2 you have an EXN2000). For the second EXN4000 depends on what you want. You can add to the first using the short 50 cm infiniband cable (out to in schema) or you can add to the second controller using 0b ports on boths.
You then have to plug an LC/LC fiber patch from the 0a HBA ports on the N3600 on both heads (A20 stands for active/active). And proceed with instructions...
