Maximum capacity size for new Ontap SIM 9.16 & 9.17

Hello Ontap Simulator Community !

I would like to know if someone got to extend the disk size and maximum capacity for the 9.16 or 9.17 SIM Ontap version ? I got extend it up to 1.61TB only (see the screenshot). I'll post here soon the procedure I made.

Thanks!

I've never seen a maximum capacity of 1.61TB. I look forward to your post.

Hi Gino,

I believe you can add at least 2 more disk shelves to a simulator node with 14 disks each

The biggest disk you can add is the type 36 and 37.

Type Vendor ID Product ID Usable Size[B] Actual Size[B] Zero BPS RPM 36 NETAPP__ VD-9000MB-FZ-520 9,437,184,000 9,458,679,808 Yes 520 15000 37 NETAPP__ VD-9000MB-FZ-ATA 9,437,184,000 10,649,346,048 Yes 512 7200

So with a 2 node Cluster maybe you can double the size, you have shown here to 3.2TB.

Cheers,

_Peter

Hi,

You have to enable diag user

::>security login unlock -username diag ::>security login password -username diag ::>set -privilege diagnostic

::*>systemshell local

%> setenv PATH "${PATH}:/usr/sbin" %> cd /sim/dev

Delete shelf 0 and 1 disks

%> cd /sim/dev %> cd ,disks %> sudo rm v0* %> sudo rm v1* %> sudo rm ,reservations

Add 4 disk selves with 14 times 36 or 37 type 9GB disks.

%> sudo vsim_makedisks -n 14 -t 36 -a 0 %> sudo vsim_makedisks -n 14 -t 36 -a 1 %> sudo vsim_makedisks -n 14 -t 36 -a 2 %> sudo vsim_makedisks -n 14 -t 36 -a 3

Reboot node, Ctrl +C, choose option 4.

Create a second node, repeat the process.

You have maxed it out.

Cheers,

_Peter

Thank you for your response.

I believe the calculation should be:
1 node x 4 shelves x 14 disks x 9 GB = 504 GB

But does that actually result in 1.6 TB?

I would say that doing only this you can´t get ~ 1.5 TB space available. Did you try ? 🙂

I didn't try to add 2 more shelves to the SIM yet. I was working only with the standard 4 shelves. As I said I'll make a new post with the detailed procedure I've used. If we can get up to 3.2 TB would be great !
